Put an alternator with a trailer tire on it. Mount alternator under chassis. Make a cable that you can lower the tire to the ground for regenerative braking. There you go. You’re welcome.
@@fastinradfordable You can get regenerative braking without any of this. In fact most if not all electric cars already have regenerative braking! That is explained in the video.
Jeremy, I WAS one of those who thought about alternator on electric car. I’m so glad I watched this. You taught a 64 years old man something today. Love your channel
Steve, you are displaying integridty here. People will almost always avoid saying that they are wrong, not that you were saying you absolutely thought it an altenator would work, but I digress. Good on you!
I thought of Gasoline Engine and Transmission in the back and a Electric motor in the back The Gasoline Engine will charge the electric Batteries giving it a Thousand miles to the Gallon
@@RaggaRanksHipHop this is how big truck and railroad engines work - gasoline engine attached to a generator and electricity is used to propel electric motors. Though this solution is efficient on big machines, on regular cars you will loose more than what you get.
@@benjaminjwilson6694that's his kids, he was trying to prove a point while teaching them using real life theory rather than give them a book and let them guess, while teaching us in the process, he is making them experience it, they aren't doing this 8h a day 7 days a week(5days)... why are you getting mad?
@@dystopiancreator2618 not mad, I just frown upon kids in the work place. kids are only kids once and should be playing with their friends. this builds their social skills. if you bring them to work, you isolate them and cause them to adapt to a hermit way of life.
@Richard Autenzio If you look at the Dyno charts of an electric motor, you’ll find that voltage will always be about level (give or take about 10% between 0RPM and the max RPM), but the drawn amperage will climb from a low baseline linearly up until it reaches between 3500 - 4000RPM, then it’ll begin coming back down at a decelerating pace, but the RPM will keep increasing. Basically, to get an electric motor to accelerate from 0 to around 4000 RPM takes a lot of power, but getting it from there to 8000 - 10,000 RPM takes less and less power. In much the same way it takes much more effort to pull a heavy cart from a dead stop to keeping it rolling once it has some inertia, an electric motor takes less energy to maintain or even reach higher speeds than it does to get it up to a lower critical speed. This is why cruising in an electric car at 40 - 50+ mph is much more efficient than trying to drive in the city, even with a similar amount of slowing down and accelerating (say +/- 10mph every few minutes).
You are a great teacher Jeremy. You use facts and proof through logic and science. I'm happy your children are lucky enough to have you as a teacher. Great job teaching your own children and making it fun.
I know, right? It's really a giant hamster running in a running wheel hidden behind a curtain. That way they can say there's no battery or plugged-in power source.
I obtained my BSME in 1962 (Mechanical Engineering degree) and I only wish I had had ONE instructor in college, ONE mentor-leader in my industry/job, more than a couple of employees under me later, - that were as adapt in ability and articulate to communicate these basic concepts as you! God has blessed you and your family. Keep it up!
be a better idea to just use solar panels to charge the battery's cause the solar panels at least make direct current which will recharge a battery verse using an alternator which will burn more energy then make to recharge the battery
I've seen so much, experienced so much, in my career. Now I'm seeing a bright young engineer get passed an aging power plant to manage. I see him working so hard and getting burned out. The outgoing manager is about to retire and works from home. This guy doesn't have a mentor to help him transition. I feel really bad because this is not supposed to be how learning a new job should go. There's nothing worse than having to learn as you go with no one to teach and train you. It's like reinventing the wheel for no reason.
@@raven4k998 You can order such a car with Solar panels already: Search for Sion from Sono Motors. They have some more concepts, but they are further away from production. They already have the manufacturing place sorted out and also have some real cars on the road already. While it sounds Chinese, they will actually be built (I think, from my memory) in Munich area, Germany. P.S.: Just saw, despite 45000 Pre-orders! (!), they cancelled the programme... what a shame. But the Company survives and offers the technology to other manufacturers (They have onboard already Scania Trucks and others) But I really wonder what has happened in the background to make them back down. After all, 45000 Reservation, with pre-payment!, is quite something...
This is by far one of the best educational videos i have ever seen 1. He didn’t require let a lone ask you to watch his previous videos to follow along with this 2. Doesn’t make you feel bad for not knowing 3. Explains things simply enough to understand but at the same time does not talk to you like you are a child Thank you for the video 😁
Everything about this video is fantastic, and I only had one question when I got into this after I learned he was debunking myths about energy... and he answered it in his pinned post about regenerative braking. :D
Thermodynamics tell us that energy cannot be created out of nothing. Energy changes state but each transformation creates heat losses. Bottom line: perpetual motion machines do not work.
Tbf the teachers are constrained by time they have to teach the students the basics. Different students have different level of passion for knowledge based on their upbringing. Therefore the depth of the topic needs to be explored by the students themselves in their own time. Their interest for the knowledge can be increased more if their surrounding is constructed to be towards practical use of knowledge which made them see its usefulness in daily life.
even with this video people believe on perpetua motion or getting energy from nothing, i read a old book in the '90 about energy, "energy only can be changed, can't create energy from nothing" also is one of the rules of physics
This is the first time I have come across this channel. I am 57 and always like to learn. Although most of this I knew from school and work that I have done in my life. I enjoyed the simple way of explaining to us mere mortals. Great to also see you having fun with the kids as they learn. Enjoyable
@@brandogeberbin7563 why do you say that? I imagine he'd run so many mental circles around you that you'd get dizzy. I suspect you do your "research" on Fox News and PragerU? Lol
@@bigplanett Fox news? Has nothing to do with my snow plow business for 20 years. Or Ford upgrading the alternators to 390 amps that they put on the 6.7 diesel trucks. or the second mount for the alternator for 2 390amp. Oh wait i was having my alternator rebuilt to that amps before ford made them Adam cole just as stupid as the teacher!
You sir, are an awesome teacher. I'm 60 years old now but when I was back in school you would have had my full attention because you make it fun simply by enjoying what you're doing. I enjoy listening to you.
You can tell he's a teacher, I felt like I was in class watching this. You are very intelligent and your kids are going to be extremely smart with you as their father. Keep up the good work, and keep up the teaching...we all need to learn what we can to keep up with this world, and nobody knows everything. Knowledge is priceless :)
Knowledgeable individual but needs to open up to the possibilities. And sometimes, it might take a lifetime, an example Albert Einstein and many others
@@cruzfernandez4554 the man is sharing his grasp of how all these things work, and that is worth a lot. He is simply describing the practicalities of a system. None of the suggestions he got and dealt with in the video are new, or outside the box, or hold any possibility outside of the knowledge he already has. He doesn't seem closed to "the possibilities" at all.
if it wouldnt extend the range then why are hybrids a proven point that this works? bro said thats why they dont put alternators in them already, but they do, all the brands. it also puts a load on the engine but somehow it extends the range. you dont need all that torque just cuz u wanna go go 0-60 in 2 seconds. accelerating that fast is inefficient in itself. he thinks the electric motor is gonna use more power because of a load, but thats not how it works, the alternator steals energy from the already overpowered motor, extending its range by making it not as powerful. he literally explained it in the gears comparison. half the weight capacity for double the speed, or double the weight and half the speed. its the same concept why electric trucks r gonna require bigger/more motors to haul alot of weight. same concept why a v8 gets less mileage than a 4 cylinder. if you were to limit the v8 to only use 4 cylinders, it would also extend the mileage. thats exactly how regen braking works
@@og4372 i feel like it still would be beneficial even thru software, or a load, since the motor is already an alternator, all engines have an efficiency curve look at the tesla graphs, if you hit the juice pedal its less efficient. so there is a way of adding another 10% in miles. also ill never understand y people r so excited about efficiency, its not like the company selling you the product is gonna pass down those savings onto the customer, lol like so what that gas is inefficient, when itll cost less than electric that is 100% efficiency, whats to gain other than ego points. and so what that gas doubled in price, electricity went up 4x in price, lmfao, and theres no more to gain from it other than price slowly getting recked by the demand we cant provide
Ya this felt like 8th grade I'm not sure I knew all this then but I mean I'm 34 and learned nothing and how he was talking at first about the comments about what about this or that really made me lose faith in our society
This was easily the clearest demonstration I’ve ever seen of why perpetual motion does not work, presented with the same patience and humor as the very best of teachers. I can’t wait to show this to my kids.
As a teenager some 60 years ago I had a bicycle with a wheel-driven dynamo that powered the lights. It was noticeable just how much harder it was to cycle the bike when the lights were switched on.
i had something like that too. the problem is. those arent made efficient. we are wasting alot of energy to drag. there has to be nrwer version that converts energy better. and led lights use less energy. im sure it can be alot lighter to peddle
I was talking to an engineering student doing a year in industry with us. He did not realise how much harder it was to turn a loaded alternator than an unloaded one when I was talking about the work input during load shedding (power trips off type of change). It was only when it started to get dark at work leaving time in late October that he found his own proof. He rode a motor bike to and from work and when he was leaving he started the bike and let it tick over as he put his helmet on. He then put the lights on and heard the engine slow down, switched them off and the revs picked up again. The next day he came in and told us he had never even thought about the lights using fuel as being significant.
I know someone who decided to add an old dynamo to an ELECTRIC bike. Somehow thought that turning electric energy to kinetic then back to electric was more efficient than simply driving the lights off a battery....
I also had one . Although not 60 years ago. It was a small motor that when touching the tire would produce power for lights .. and yes it did create drag ..
So basically, this has already been completed with regenerative braking... That is the only 'lost/wasted power'... When you are stopping. Absolutely amazing video. Thank you!
When I was 5 I had a light on my bike powered by a generator. It was like riding with the brakes on. When I was 5 I knew you were right. Great explanation TY.
In essence you were using the same principle ev's use to brake the car. good old days. was fun to flip the bike over and spin it so fast it burned out the bulb.
I too was a smart kid, and built myself a battery powered one, and It was much brighter too!🤓 Like have you ever heard of a deer caught in a bike light? Well I did! I wanted to add a recovery generator and a quick set/release lever for recharging down hill, but the tech was not quite there yet in the 70's in any practical sense, nor could be had for cheap.☹
You have a talent to teach. I'm an old man having served on Nuclear Submarines as a reactor operator 1962-1966. I am very qualified to make this statement Sir. You have a talent to teach. Please keep it up. BWV
@@spideybuildscars I do, here is one. I have written 150 of them: Bad behavior I have an interesting story I needed to write and wanted to share. I served on US Navy Submarines in the early 60’s both diesel and Nuclear boats. I was a Navy trained reactor operator when on Nuclear boats. In the fall of 1963, moored in New London CT there were a lot of anti-nuclear folks that on week ends and holidays would harass us by water skiing as close to our boats as possible yelling obscenities. It’s just like today but 60 years ago and it wasn’t just a few, there were many. Often I was standing topside watch with another mate, both of us armed with Remington 1911 .45’s. We tired of it over time and concocted a plan. Back then our boats had four sanitary tanks each capable of holding 1,500 gallons of human waste and they were blown with compressed air into the Thames River by the below decks watch during their 4-8 AM watch. Can’t do this today but it was different back then. I told the below decks watch to not blow these tanks to the river until I told them. When these guys on water skis came by we blew them into the Thames river right into their skiing path and they were skiing in our excrement. It personally made me feel better. I won’t tolerate bad behavior in a man. We are still seeing it today though.
@Bruce Vetter After USS Cole this wouldn't be tolerated today. Each command has some newer forms of deterrents against this kind of "going up to the boat as close as possible" behavior up to and including warning shots. Justified to keep the crew safe. RIP those lost in USS Cole terrorist bombing. -Also sub vet
@@brucevetter8511 , I can not with certain honesty say I haven’t performed actions I am not proud of on individuals who were demeaning for the path I had chosen. But over the years I have come to learn, and teach, to teach these people differently. When I can, I will walk up to these individuals and offer my hand. And whether they take it or not, I thank them for paying their taxes for I could have a career. And I thank them for exercising their 1st amendment rights that so many good soldiers fought and died for. That usually makes them think about what they are doing.
I didn't know that I was stumbling into a physics, electrical, and mechanical engineering course, but I'm glad that I did. You did a phenomenal job of breaking this down.
Yes, great explanations but that still doesn't answer the BIG question I have in mind. That question is: "Then how do you explain why they even put/use alternators in gas powered cars!? They find it worth it. Why? And why, at least for electric accessories like a car AM/FM radio, wouldn't it be worth it for electric cars as well (with only the way the same basic type of vehicle is powered being different)?"
electric motors use next to no power to turn motors, ever see how small the battery is to turn the motor on a hybrid? not much bigger than a battery for a Power Wheels kids car and the crank amps arent as high. With traditional motors they need spark, unless it's a diesel, to ignite the fuel which can't happen without a big amp battery. If you make a lot of stops and have to start and stop the motor it puts a strain on the battery and it eventually dies. That's where alternators come in, while it may not be effective with multiple motor stop/start cycles-nor will the starter motor last as long- it prolongs the life of the battery until it's internal design is wore out. Most V8s need 750-1000 crank amps or CA. CCA is cold crank amps which comes in play for regions where it gets close to freezing obviously and that's why it's also listed on the battery. When the starter motor is powered by the battery using 12v it uses a small motor and gear assembly with a Bendix actuator and wound magnet to push that little gear to mesh with the HUGE flywheel...little gear moving a huge gear that mechanically turns the vehicle motor until fuel takes over. The time before fuel takes over, which also type of fuel, age of motor, efficiency, etc come into play before it takes over uses a lot of power and this being amps. the alternator is designed to take some of the motor power to replenish the battery close to capacity as long as the system is complete and the battery can accept it. Corrosion will inhibit and make that system work very hard and destroy it over time. Bigger motors need bigger alternators and higher CA capacity batteries because of the little gear to big flywheel ratio like he used in the video, it's a trade off. But in the end it's only as good as the parts and how well they're maintained, much like our bodies 👍
@@krystoffersprague6100 this doesn't tell me anything I don't already know. My point is, even with friction of the alternator belt, they find it worth using an alternator on a gas powered car to charge the battery. An alternator is a belt driven generator.
@@kevine9376 true but it's taking too much power that the electric vehicle can better use to go further, based upon the video presentation. Now maybe if different ratio gears were used to the alternator and is took less revs to generate more current but with a bigger amp system it could compensate but again most electric batteries are massive. Even if it was a tickle, it'd still take more energy to attempt that tickle than to go further...unless breakthroughs in tech allow it to happen. It could be hidden purposely though.....
not going to lie, I clicked this video hoping to see this work, but I'm surprised how informative and educational this was! Thank you so much for sharing!
I tried to explain this to my kids but they never believed me. I was a mechanic and I’m also a Ham Operator, both these fields use everything that you are teaching. I also tried to tell them that math drives almost everything. Now that they are in there mid to late 30’s they think they have stumbled on a fact that has been a mathematical reality forever. Thank you Jeremy for this video. We need more people like you in the world!
So true, and it's the lack of education and critical thinking skills that fuels the growing communities that hold conspiracy theories to be true (science, political, medical...etc.).
@@goodcat1982 yes, but then a lack of education and critical thinking perpetuates the lie. Most flat earthers don't post fake videos, they just believe them.
Jeremy as a 65 year old retired Powerplant engineer I get a real kick out of your enthusiasm to spread knowledge to the interested, confused, frustrated, and indignant. Those with an open mind will understand and grow in knowledge. Keep it up!!!
If I had had the benefit of this degree of clarity of explanation in my teens, I might've considered going into physics or engineering, instead of linguistics and human physiology. Hats off to Jeremy Fielding!
I have no doubt you *might have considered* it. 😉 But I think it's at least as likely that your lived experience heretofore is inextricably linked to your appreciation for this now.
Jeremy, I’m a retired sixty year old defense engineer/ 5th Gen warfare tactician…. I wanted to tell you that it was so refreshing to to watch your video . God gifted you with the gift to teach and communicate …. Your are a great engineer and teacher. Keep up the good work pal. I look forward to to seeing more of your videos …
God didn't gift him. he just has rare Sense,. Because sense is not common anymore. There's no such thing as God. You list your background Like it's Proof that you're so smart. Then you turn around and talk about God, haha. God was only invented to Control other people. In a world without religion, good people will be good and bad people will be bad. The world with religion bad people will be bad and good. People will do bad things in the name of Their religions or for their Religion.
You have a very special talent for explaining a complex subject that anyone with a bit of common sense can understand while keeping one's attention. I sure wish there were more folks like you among us.
I agree that he has a talent for explaining the subject, but I disagree that this is a complex subject. It's a lot like buying something with sales tax. Sales tax representing the waste energy. You have $10, you want to buy a $1, and there's 10% sales tax, so it's going to cost you a total of $1.10. Now you have $8.90, not $10. Then for plugging the alternator into the battery to charge it, you haven't opened the soda and want to return it. Well there's a 10% restocking fee. So you're only going to get back $1.10 minus the 10% restocking fee, which ends up being $0.11. So now you've spent $1.10 and gotten back $0.99. So instead of starting with $10 and having $10 despite returning the soda, now you're 11 cents short, so you have $9.89. You've lost money just by trying to get your money back for an unused product. Keep doing that, keep buying and returning the soda because we're talking about an engine running an alternator, every moment of time it loses energy, so to extend the analogy to this, you have to be constantly buying and returning the soda every nanosecond. Before you know it, you're out of money. So the motor is going to grind to a halt.
Finally lol as someone that went to school for electronics, I understood right away why an alternator on an electric car was a pointless idea lol. NOW I have a video I can link to the people I argue with that will actually TEACH them once and for all lol.
This guy should be waaaay bigger. So much information straight out of the gate, no warm up whatsoever. But it's digestible to even someone like me who has no initial interest in the subject. 👍🏻 Great Job Teach! ✊🏻♥️🌟
WOW !!! if Jeremy had been my teacher in school i could have become anything. i was never able to stay interested for long periods in these subjects you have a talent to make things interesting. gifted to teach.
Serious question. I get what you’re saying, but isn’t the variable gravity and drag? And therefore magnetic fields are the solution in some way, shape or form? Our planet oscillates in a cycle… what put that in motion, what keeps that in motion? Perpetual motion is real, we just haven’t figured it out. Great video though!!!
I was fortunate enough to have had not one, but two wonderful electronics teachers in high school (Thank you ever so much Mr. Wright - RIP, and Mr. Conway of Westside Skills Center in Balto. MD.), but wish more teachers, like Jeremy were out there helping these kids THINK, as well as learn. Your children are truly blessed to have you for a father.
Bravo! Guys like you deserve a reward for putting content like this out there making science easier for people to understand. If think Force is quantitative then you've saved this world a tremendous amount by producing this video and many of us thank you for that
Jeremy, it is refreshing to see someone on RUclips who has such a clear understanding of physics and can explain the concepts so well. I liked the illustration of work and power using your kids to carry bricks. I especially liked it when you suddenly appeared on screen trying to "motivate" them to increase their power output. Your transfer of "power" from one plastic cup to another was an excellent way to illustrate losses of energy when going from one device to another. You are an excellent teacher. Thanks for this great video.
When I was at school, I learned 'energy cannot be gained nor lost, only converted' and 'nothing is 100% efficient'. Knowing these two facts debunks most of these perpetual/free energy type things within moments. I discovered your channel by chance, and really enjoyed the video. Subscribed :)
@Land and Lore Photograph Off Road Adventures e does equal m times c squared our boy Einstein proved that neither can be created or destroyed only converted.
@@bullbutter2931 provided the turbines spinning the generator output more power than the increased power requirements that the reduced aerodynamics of the vehicle I don’t see why that couldn’t be a range extender. I’m betting that it wouldn’t work or else the car companies would be doing it.
I really enjoyed this video. I’m one of those people who thinks ‘just add a bigger alternator’ but know deep down it isn’t that simple. The demonstrations shown here show in a visual way what scientists and mathematicians see through equations on paper, and it’s really helped me to understand exactly why ‘just adding bigger things’ will never work. I’m really grateful for this work, it’s simple, bite sized, honest and relatable, and I’m subscribing. Thanks you 😊
A science teacher interested in real science? Is this real? I Would really like to know how to calculate how much is lost in each conversion of chemically generated (or would that be converted from what its stored in? Like gas, coal, nuclear?) required to get the energy generated/converted so much more efficiently than could ever be done in the engins under the hood of my car before its finally the electrical energy stored in batteries in an electric car being generated/converted into the mechanical energy required to turn the wheels of that car. So many steps must result in massive loss. From stepping (transforming?) It to high voltage, or even dc to transmit it from the power plant miles away where it is somehow magically created with ZERO emissions, Then converted to lower voltage & back from DC to ac at my city's substation so it can fit in my citys lines to be carried close to my home where it must be transformed to yet lower voltage before into my smart meter, then into the car charger Newsome was just a couple of weeks ago was telling everyone not to use because we had a couple of warm afternoons , & pg&e shuts off the power every time the wind blows & the grid can't provide what's needed now , Because those who have now made gasoline illegal in a couple years (Right about the time Claus has declared we will own nothing. But none of all this is related, of course) they had a duty(an important word to define) to qt least maintain the grid, & If they are going to make laws requiring 5 TIMES the current load (pun not intended) on the grid they had a DUTY to ensure they improve the grid accordingly. & the people have a duty to hold them accountable for being derilect! But I digress. So 240vac entered into the home & must be converted to 12 vdc (=LOSS yet again. Is that the 13th loss now? Ive loss track.) to go into the batteries, to be converted into chemical energy to be stored in those batteries where it must be converted back from chemical to electric energy before it can be converted to mechanical energy to turn the wheels. If only ten conversions/transformations (& rhere are far more) & you "only" lose 10% each time.... when fact is more like 30% loss...must be converted be used
im not book smart i stoped careing in the 4th grade and even i learned about friction do they not teach these things ?my son grade a student dosent understand fluid dynamics this is concerning to be honest
" Would really like to know how to calculate how much is lost in each conversion of chemically generated (or would that be converted from what its stored in? Like gas, coal, nuclear?) required to get the energy generated/converted so much more efficiently than could ever be done in the engins under the hood of my car before its finally the electrical energy stored in batteries in an electric car being generated/converted into the mechanical energy required to turn the wheels of that car." The fuel you burn in your car has also gone through a series of conversions and transportation in order to become gasoline in your tank. It has to be extracted, transported to a refinery, refined, transported to storage, put in a delivery truck, added to a storage tank at your local gas station, and then dispensed into your tank. Each of those also takes energy (particularly the refinery bit, but the transport bits can also be pretty costly). Then your gasoline engine is about 20-35% efficient at turning the energy stored in the gasoline into motion. In order to compare that with electricity, you have to really look at the exact source of electricity. Taking natural gas, the extraction process is about as energy intensive as oil extraction, but it doesn't need refining, and converting it to electricity is about 45-57% efficient. From there transporting electricity happens over wires and while it is not lossless, it involves far less loss than trucking liquids. Once it is in your car (charging is another loss, but in the 5% range or less), the car itself is pretty close to 100% efficient at turning the electricity into motion. Of course, there are some losses for heating when it's very cold out, but the gasoline car is better at that only because there is so much waste heat it can be "thrown away" into the cabin - an electric car only has a fraction of those losses when it needs to produce heat. Electricity can also come from many sources, as electric cars don't care how their power was created - it's all electricity. So you can burn coal, burn natural gas, generate it with solar, tidal, nuclear, wind, or any one of a number of sources. So you can use the source that makes sense locally to generate electricity. "& pg&e shuts off the power every time the wind blows & the grid can't provide what's needed now ," Electric vehicles can (in large part) be charged at times when the demand is lowest and the supply is highest. Other electric uses have a more difficult time moving. So EVs can provide demand when the grid has excess supply (in most places this is at night when businesses are shut down, but in areas with a lot of solar power this can actually be during the day when solar plants are cranking out power). Most if not all EVs can easily be programmed to only charge when demand is low - and if you set electric prices appropriately (Time of Use plans) your EV drivers are going to be the portion of your demand that is the most easily-moved.

I love that you used kids to illustrate work. That’s an amazing feat in itself. This video is getting shared with the grandkids because you’re a great teacher and so they can learn about work (the science and the labor).
I, as well, was one of those people that never understood why they didn’t just use the tire/axle rotation to recharge the batteries on electric cars. And I may have argued that my point was valid had I not watched this video. I’m old and set in my ways so it takes good logic to sway my thinking. Thank you for this informative video…it shows you’re never too old to learn something new.
I wish that I had had teachers like you when I was a young man. You are very clear, concise and your examples are extremely creative and illuminating. Congratulations!
You explained this in such a simple and effective manner that anyone can understand. I love that you're teaching your kiddos all of this and involving them. It's a breath of fresh air to see a parent actually teach their kids something these days!
I must be stupid. Feels like school again. Once you don't know what he's talking about, you start to zone out. What is the output of kids? I couldn't figure the answer out.
I learned all about this when I mounted a headlight on my bicycle as a kid. It came with a little friction generator that would run against the side of the wheel to power the headlight. The amount of drag that tiny little generator caused was absolutely amazing. I could feel it *immediately* in how much more work I had to do to get the bike going or getting any speed with that tiny little generator spinning against the wheel.
What would be more scientific would be to add a switch to the light's circuit to see how much energy is lost to just the internal friction of the dynamo with the light off versus how much more energy is is needed to when the light is switched on.
@@h8GW Yeah, the bearings on the bit that went against the bike tire and the dynamo were usually hot trash, but you could still feel the drag drop off just a bit when the bulb burned out. Adding a switch would still have been a useful exercise in terms of being able to repeat the drag changes many times, to be sure.
I absolutely love how well you conveyed the transfer of energy between such seemingly alien systems. I have a BS in engineering, however, while I was in high school I could not wrap my head around gears, teeth, size ratios, and efficency transfers. Watching this, I truly wish I could have had these kinds of videos available. I have such appreciation for people who take the time to explain, in such a concise manner, things like equivalent exchange. Hope to see more videos like this as opposed to others trying to disprove the earth is round.

Jeremy….you are so 1000% correct! People have been trying to create perpetual power systems for many years. But until you somehow reduce your system resistive losses to zero….you’ll never get there. The conservation of mass and energy is absolute!
I'm a process/ manufacturing engineer with a degree in mechanical engineering so this is basic for me but I still enjoy watching these video teaching the fundamental of physics in an engaging way to future generations. Teachers like this are one of the big reason why I was so interested in engineering when I was young. Good job sir!
I’m not an engineer so I’ll ask my dumb question. Say you build a light weight alternator that didn’t take a lot of torque to turn. Could you turn it sideways and add a pinwheel on the end of the shaft, then have a wind funnel on the car so it charges when you drive 35 MPH or faster? Obviously this isn’t going to do away with the need to charge but if you build one into each side of the car with intakes and one on the roof it might in theory be able to drastically extend the time needed between charges right? I work in green energy so I was just trying to think outside the box and can’t find an obvious downside to this. What do you think?
@Dustin Bridges The main issue, if you were to do this, would be the added drag from the wind generator/ wind turbine. Especially, for an EV, drag has a huge effect on their efficiency. I haven't done the math on this but I am willing to bet that the increase in air resistance, turning the fan, would out way the energy generated. The only time it would generate more energy than the car is using is when it's going downhill but by that point, you should just use the motors driving the wheels as generators which all EVs do use (regen braking). Hope this answers your question :)
May I ask if that is the engineering job you wanted? Or did you have other fields of engineering you were interested in? I always wonder what people want to do with mechanical engineering and have a hard time myself figuring out what I'd want.
Dude, you have such a great video presence. I like the casual feel, it doesn't feel too scripted and it feels like you really are just teaching. Thanks
Such a fantastic video! Thank you so much for sharing. I sympathize with you about how people persistently seek a perpetual motion machine, continually asking questions as if there might be a magical way for one to work. As a Mechanical Engineer, I remember my professors discussing many of the topics you covered. You simplified some of these concepts in marvelous ways that I've never seen before. It was a very enjoyable video. I've been trying to explain torque, power, and work to a close friend in relation to a bicycle and a manual transmission, and I think this video will be very helpful.
Love the way that you break down your explanation of things, and offer a few different ways to explain your point. Informative, not condescending, thorough and easy to follow. Thanks for creating videos that are actually enjoyable to watch.
This reminds me of working on stuff with my dad teaching me stuff while doing yard work. I grew up to be an engineer. What a great video, and I know your kids will look back at how great it was to have a parent teach them all this stuff.
When it comes to engineering, math, physics, and related subjects I end up with a glazed look and understand nothing. I admire people who can understand and use them to solve practical problems or explain why it can't be done. You explain the basics clearly, instead of trying to make yourself sound brilliant. I envy your children and students for their wonderful opportunity to learn from a true teacher. Thank you.
I have a small crank-powered light. I discovered years ago that it is much easier to crank with the lamp turned off than with it on. The misconception about alternators seems to be "it's already spinning" without taking resistance/load into account. I found my light was the perfect demonstration of this fact.
Thank you Jeremy for taking the time to make this extremely helpful video. As a father of 5 (all boys except for the first 4), I understand that in order for you to make this happen requires a family effort. Again, thank you and your family.
Great video. I already knew the idea was bogus, and using regen braking is basically the same as adding an alternator. Mostly I clicked and watched because I was curious as to how someone else would explain this. You made it so easy and simple, anyone could understand. Great work.
Thank you for your video. I'm over 70 and when I was a freshman, I came up with the idea of hooking a generator to a motor so that the motor would run forever. My science teacher walked me through the reasons it wouldn't work. I finally believed him when we set up a test in the lab and the motor stopped turning almost immediately. We spent a week of lunchtime breaks investigating why until I finally got the fact that energy is a constant and can not be created or destroyed. I fell in love with math after that experiment and went on to spend my working life as an engineer. My only regret today is that I have forgotten his name but not the time and the love for science he gave me..
you honor what he taught you, which is better then remembering his name, imo i would rather people remember the contribution and effort i put in, then my name or the color of my hair/eyes, so i wouldn't feel bad at all, the man loved what he did and passed that on to you, and hopefully other students :)
I first read of regenerative braking in a very early copy of Mother Earth. It was a hydraulic based system. At the time I thought that the author had not allowed the added weight of needed pumps and such. A few years ago driving a nephews Tesla S for the first time, I was shocked at coming up 20 feet short at my first stop sign due to for the regenerative braking.
I thought this stuff was possible when I was younger. Eventually I understood that with the very basic laws of physics, none of this is possible, especially perpetual motion. But I really love the way you have explained things, and I will use some of your analogies, when trying to explain to mates why these amazing things they have seen on RUclips just aren't possible😂
My first time seeing your videos. Absolutely wonderful! I'm a fan now. In a world of "alternative facts" nonsense, your low-key, rational, logical videos serve a much broader purpose. Thanks!
Using the cups with water was a great visual, really helps visualize and explain the process in simple terms that pretty much anyone can understand. Really wish I had teachers like this when I was in school. Then I might have actually paid attention. Thanks for sharing. Edit: One thing people should take away from this, is that if it were this simple. It would be common place on every EV. I had a coworker say they should put turbines on EVs to help recharge the battery while driving.
@@frotobaggins7169 Noise and windage (moving air) as well. Where I worked we built high power equipment with shaft drives. The shafts were enclosed for safety reasons and we had to arrange cooling through the casings due to windage heat cooking everything if we did not remove it.
The real power here is knowledge, this gentleman has brought the fact into to picture in an informative and interesting way. We need more teachers with his uplifting approach to learning. A pleasure to watch !
You are spot on. I am an Auto Electrician. Based in the UK. and when a customer would come in. Because their belt a squealing. I try to tell them that they. Probably have just started the engine. And the battery has used some of its power. And it’s asking the alternator to put mor power output. Basically the alternator pulley is resisting the rotation, it wants to stop or turn in the opposite direction of the engine. Which is why the belt is squealing. Because under total load. A large output alternator would take up to roughly 5 HP to drive it. The same if your engine is idling. And you turn on the AC. You will see your rev-counter will lower. Momentarily. Because of the load it takes to run your Air Conditioner. On an older car the revs will slow down and stay there. Modern cars. The ECU will command the engine to raise the revs back to the original idle speed. Apologies for making a simple explanation. Be this long, but it is the same principle as you explained. Everything takes powers to turn the pulleys. I hope that all makes sense.
Very impressive explanations. This grandma, with no college, did not get lost. You had me at "you cannot create or destroy energy, you can only change form." You've taken Einstein and given us a hands on demonstration that brings that reality home. Thank you Jeremy!
The laws of thermodynamics stops this from happening. Also the laws of conservation of energy. It can be done in an environment free from these laws. Some kind of vacuum or something.
I came back to watch this again because I appreciate your understanding of electrical systems which has been my line of work for 40 years. Electricity is fascinating and very complex which is why most people don't understand it. Unfortunately not fully understanding something doesn't stop some folks from giving you their baseless opinions. It's refreshing to listen to someone that actually knows what he's talking about. I wish we could sit on the front porch together and have a beer or ten 🤣and talk shop!
Agreed. I can't count how many times over the years that I dearly wanted to reach across the conference room table and whack someone up the side of their head. I think the most idiotic case was when I needed to add a 200A panelboard and the owner wanted to know why I couldn't just tap into an existing 30A branch circuit instead of adding a feeder from the distribution panel in the electrical room.
You are an amazing teacher! I'm in my 50's and I only marginally understood pulleys and gears before today. Now, I fully understand them, plus so much more. Subscribed!
Where were you when I was in school?? I always learned better with visual explanations then numbers on a chalkboard. All thought I already knew this, the way you show and explain things I would have done far better in school in the 80's. Iv have learned a lot more in my late 40's then i ever did when I was in school. Thank you for being such a good teacher and God Bless!
Watched the whole video even though I already knew all of this. Always good to brush up on the fundamentals and see new demonstrations. There are so many ways to teach the same principles. Thanks!
@@tpike32 Common sense and a bit of knowledge will get you far. Experimentation is always fun too though! Proving something for yourself can be powerful.
What I love about this man and his channel is how good he is at explaining things to a level that anyone can understand any given subject. He is very smart but even better explaining things.
You're an amazing teacher. I wish all teachers were as patient and demonstrative as you were in this video. I've had many teachers who only delve into theory and formulae rather than providing demonstrations for students to learn from. It's the teachers that take the time to design such demonstrations and to explain exactly what's going on that I've learned the most from.
You just earned my subscription. Thanks for breaking it down to very basic analogy. I have been a HVAC technician for almost 20 years and have always loved taking PSE motors apart and now that most newer higher efficient ac units are now using Modulating variable speed Or ESM motors I’m starting to take those apart to see how they work.
You are an AMAZING teacher! I literally burst out laughing when you added "motivation" to increase the "power = force x distance / time" equation! You seem like a super fun father and your kids look like they had fun too.
I smile every time I watch you break down things that I understand but, can't put into words. You're a genius and greatly appreciated. Keep up the good work! And thanks for sharing. Long Live the Fieldings!!
Bro, if I had someone like you teaching me in school 40 years ago, I most likely would have grasped all of this knowledge far better than I did. I was in a private church school k-12 and never had teachers. The help were parents who donated time to monitor the students, but anytime I needed help, I was told to figure it out. Well, if I could figure it out on my own, I wouldn’t be asking for help. I have zero regrets in how my life has turned out, but I watch videos like this in hopes to gain more applicable knowledge of how things work. I appreciate you breaking this down as much as you have.
I have no idea how I ended up on this video, but I am so glad I did! You have a fantastic way of explaining things and I enjoy your method of teaching! Cheers!
Excellent program Jeremy. I taught Basic Electronics in my days in the Navy at Great Lakes. I was watching and remembering students asking these same questions. I am glad your channel makes it clear and concise.

FYI I do in fact talk about regenerative braking in the video! LOL There is a whole segment on it. Thank you for watching!
Put an alternator with a trailer tire on it.
Mount alternator under chassis.
Make a cable that you can lower the tire to the ground for regenerative braking.
There you go. You’re welcome.
It will waste zero energy.
And will create energy.
AND- you can easily add/remove it to ANY vehicle.
@@fastinradfordable You can get regenerative braking without any of this. In fact most if not all electric cars already have regenerative braking! That is explained in the video.
Have a look at heat pumps & see their COP. They still waste energy but they collect more than they waste.
Still hella funny that in today's day and age, its a controversial statement to say: There is no such thing as free energy. Lmao
Jeremy, I WAS one of those who thought about alternator on electric car. I’m so glad I watched this. You taught a 64 years old man something today. Love your channel
Steve, you are displaying integridty here. People will almost always avoid saying that they are wrong, not that you were saying you absolutely thought it an altenator would work, but I digress. Good on you!
I'm 60 and had the same thoughts. Willing to learn and he explained it easily to follow.
I thought of Gasoline Engine and Transmission in the back and a Electric motor in the back The Gasoline Engine will charge the electric Batteries giving it a Thousand miles to the Gallon
@@RaggaRanksHipHop this is how big truck and railroad engines work - gasoline engine attached to a generator and electricity is used to propel electric motors. Though this solution is efficient on big machines, on regular cars you will loose more than what you get.

As a father, I lost it and approve😂
So Jeremy how does an electric over drive work on a car?
@Richard Autenzio If you look at the Dyno charts of an electric motor, you’ll find that voltage will always be about level (give or take about 10% between 0RPM and the max RPM), but the drawn amperage will climb from a low baseline linearly up until it reaches between 3500 - 4000RPM, then it’ll begin coming back down at a decelerating pace, but the RPM will keep increasing. Basically, to get an electric motor to accelerate from 0 to around 4000 RPM takes a lot of power, but getting it from there to 8000 - 10,000 RPM takes less and less power. In much the same way it takes much more effort to pull a heavy cart from a dead stop to keeping it rolling once it has some inertia, an electric motor takes less energy to maintain or even reach higher speeds than it does to get it up to a lower critical speed. This is why cruising in an electric car at 40 - 50+ mph is much more efficient than trying to drive in the city, even with a similar amount of slowing down and accelerating (say +/- 10mph every few minutes).
could just say hes hitting the accelerator
You are a great teacher Jeremy. You use facts and proof through logic and science. I'm happy your children are lucky enough to have you as a teacher. Great job teaching your own children and making it fun.
The hardest part of building a perpetual motion machine is figuring out where to hide the batteries.
😂😂😂😂
or the power cord. 🤣🤣
I know, right? It's really a giant hamster running in a running wheel hidden behind a curtain. That way they can say there's no battery or plugged-in power source.
i just say induction charger
hahahaha ..10000000% agree
I obtained my BSME in 1962 (Mechanical Engineering degree) and I only wish I had had ONE instructor in college, ONE mentor-leader in my industry/job, more than a couple of employees under me later, - that were as adapt in ability and articulate to communicate these basic concepts as you! God has blessed you and your family. Keep it up!
be a better idea to just use solar panels to charge the battery's cause the solar panels at least make direct current which will recharge a battery verse using an alternator which will burn more energy then make to recharge the battery
I've seen so much, experienced so much, in my career. Now I'm seeing a bright young engineer get passed an aging power plant to manage. I see him working so hard and getting burned out. The outgoing manager is about to retire and works from home. This guy doesn't have a mentor to help him transition. I feel really bad because this is not supposed to be how learning a new job should go. There's nothing worse than having to learn as you go with no one to teach and train you. It's like reinventing the wheel for no reason.
@@raven4k998 You can order such a car with Solar panels already: Search for Sion from Sono Motors. They have some more concepts, but they are further away from production.
They already have the manufacturing place sorted out and also have some real cars on the road already.
While it sounds Chinese, they will actually be built (I think, from my memory) in Munich area, Germany.
P.S.: Just saw, despite 45000 Pre-orders! (!), they cancelled the programme... what a shame. But the Company survives and offers the technology to other manufacturers (They have onboard already Scania Trucks and others)
But I really wonder what has happened in the background to make them back down. After all, 45000 Reservation, with pre-payment!, is quite something...
This is by far one of the best educational videos i have ever seen
1. He didn’t require let a lone ask you to watch his previous videos to follow along with this
2. Doesn’t make you feel bad for not knowing
3. Explains things simply enough to understand but at the same time does not talk to you like you are a child
Thank you for the video 😁
100% agree, this is a great comment, you’ve said it better than I ever could, nice one 👍🏻
Everything about this video is fantastic, and I only had one question when I got into this after I learned he was debunking myths about energy... and he answered it in his pinned post about regenerative braking. :D
@@UnTamedMustang Not following-- superchargers and alternators do completely different things.
In his Video Description section, he did say "A followup to my Nikola Tesla Video"
Wow, I'm in my mid 40s and I think this is the best lesson I've ever experienced. Kudos to you, your students have struck gold
Man the education system could use more people like you. None of my teachers ever explained things with even half the passion and enthusiasm you do.
Thermodynamics tell us that energy cannot be created out of nothing. Energy changes state but each transformation creates heat losses. Bottom line: perpetual motion machines do not work.
We have to overcome our culture of feeding egos to produce more good teachers. We have a culture that values hurt feelings over facts.
When you realize that youtube can replace public school . . .
Needs more King James Bible in schools.
Tbf the teachers are constrained by time they have to teach the students the basics. Different students have different level of passion for knowledge based on their upbringing. Therefore the depth of the topic needs to be explored by the students themselves in their own time. Their interest for the knowledge can be increased more if their surrounding is constructed to be towards practical use of knowledge which made them see its usefulness in daily life.
Retired Electrical Engineer here. You are an awesome teacher.
I have been working in industrial electronics for 30 years and it is energizing to see great teachers like you. Good job!
Me too and it had the same effect on me. 😎
"energizing" nice pun
I once tried to wire a stand alone alternator to a table saw as a battery charger. LoL it didn’t work. Although I still believe it could.🎉
even with this video people believe on perpetua motion or getting energy from nothing, i read a old book in the '90 about energy, "energy only can be changed, can't create energy from nothing" also is one of the rules of physics
This is the first time I have come across this channel. I am 57 and always like to learn. Although most of this I knew from school and work that I have done in my life. I enjoyed the simple way of explaining to us mere mortals. Great to also see you having fun with the kids as they learn. Enjoyable

Keep up the good work, and keep up the teaching...we all need to learn what we can to keep up with this world, and nobody knows everything. Knowledge is priceless :)
Knowledgeable individual but needs to open up to the possibilities. And sometimes, it might take a lifetime, an example Albert Einstein and many others
@@cruzfernandez4554 the man is sharing his grasp of how all these things work, and that is worth a lot. He is simply describing the practicalities of a system. None of the suggestions he got and dealt with in the video are new, or outside the box, or hold any possibility outside of the knowledge he already has. He doesn't seem closed to "the possibilities" at all.
if it wouldnt extend the range then why are hybrids a proven point that this works? bro said thats why they dont put alternators in them already, but they do, all the brands. it also puts a load on the engine but somehow it extends the range. you dont need all that torque just cuz u wanna go go 0-60 in 2 seconds. accelerating that fast is inefficient in itself. he thinks the electric motor is gonna use more power because of a load, but thats not how it works, the alternator steals energy from the already overpowered motor, extending its range by making it not as powerful. he literally explained it in the gears comparison. half the weight capacity for double the speed, or double the weight and half the speed. its the same concept why electric trucks r gonna require bigger/more motors to haul alot of weight. same concept why a v8 gets less mileage than a 4 cylinder. if you were to limit the v8 to only use 4 cylinders, it would also extend the mileage. thats exactly how regen braking works
@@og4372 i feel like it still would be beneficial even thru software, or a load, since the motor is already an alternator, all engines have an efficiency curve look at the tesla graphs, if you hit the juice pedal its less efficient. so there is a way of adding another 10% in miles. also ill never understand y people r so excited about efficiency, its not like the company selling you the product is gonna pass down those savings onto the customer, lol like so what that gas is inefficient, when itll cost less than electric that is 100% efficiency, whats to gain other than ego points. and so what that gas doubled in price, electricity went up 4x in price, lmfao, and theres no more to gain from it other than price slowly getting recked by the demand we cant provide
Ya this felt like 8th grade I'm not sure I knew all this then but I mean I'm 34 and learned nothing and how he was talking at first about the comments about what about this or that really made me lose faith in our society
I am far from a science expert, but even I understood everything in this video loud and clear. I learned something today.
I just watched a documentary on perpetual energy. It went on forever.
LOL that got me
That's awesome! Best to you, Esra!

I think they missed your pun.
Then you woke up in the morning.
This was easily the clearest demonstration I’ve ever seen of why perpetual motion does not work, presented with the same patience and humor as the very best of teachers. I can’t wait to show this to my kids.
As a teenager some 60 years ago I had a bicycle with a wheel-driven dynamo that powered the lights. It was noticeable just how much harder it was to cycle the bike when the lights were switched on.
i had something like that too. the problem is. those arent made efficient. we are wasting alot of energy to drag. there has to be nrwer version that converts energy better. and led lights use less energy. im sure it can be alot lighter to peddle
I was talking to an engineering student doing a year in industry with us. He did not realise how much harder it was to turn a loaded alternator than an unloaded one when I was talking about the work input during load shedding (power trips off type of change). It was only when it started to get dark at work leaving time in late October that he found his own proof. He rode a motor bike to and from work and when he was leaving he started the bike and let it tick over as he put his helmet on. He then put the lights on and heard the engine slow down, switched them off and the revs picked up again. The next day he came in and told us he had never even thought about the lights using fuel as being significant.
I know someone who decided to add an old dynamo to an ELECTRIC bike. Somehow thought that turning electric energy to kinetic then back to electric was more efficient than simply driving the lights off a battery....
I also had one . Although not 60 years ago. It was a small motor that when touching the tire would produce power for lights .. and yes it did create drag ..
Oh yeah. And that was probably right around an amp. Maybe two amps. EV’s charge around 100 amps.
So basically, this has already been completed with regenerative braking... That is the only 'lost/wasted power'... When you are stopping.
Absolutely amazing video. Thank you!
When I was 5 I had a light on my bike powered by a generator. It was like riding with the brakes on. When I was 5 I knew you were right. Great explanation TY.

You must have neat stories to tell!
@@spideybuildscars I do, here is one. I have written 150 of them:
Bad behavior
I have an interesting story I needed to write and wanted to share. I served on US Navy Submarines in the early 60’s both diesel and Nuclear boats. I was a Navy trained reactor operator when on Nuclear boats. In the fall of 1963, moored in New London CT there were a lot of anti-nuclear folks that on week ends and holidays would harass us by water skiing as close to our boats as possible yelling obscenities. It’s just like today but 60 years ago and it wasn’t just a few, there were many. Often I was standing topside watch with another mate, both of us armed with Remington 1911 .45’s. We tired of it over time and concocted a plan.
Back then our boats had four sanitary tanks each capable of holding 1,500 gallons of human waste and they were blown with compressed air into the Thames River by the below decks watch during their 4-8 AM watch. Can’t do this today but it was different back then. I told the below decks watch to not blow these tanks to the river until I told them. When these guys on water skis came by we blew them into the Thames river right into their skiing path and they were skiing in our excrement. It personally made me feel better. I won’t
tolerate bad behavior in a man. We are still seeing it today though.
@Bruce Vetter After USS Cole this wouldn't be tolerated today. Each command has some newer forms of deterrents against this kind of "going up to the boat as close as possible" behavior up to and including warning shots. Justified to keep the crew safe. RIP those lost in USS Cole terrorist bombing.

@Bruce Vetter Thank you for your service! I agree with your assessment. "I concur. The message is authentic." 🤗😎
I didn't know that I was stumbling into a physics, electrical, and mechanical engineering course, but I'm glad that I did. You did a phenomenal job of breaking this down.
Yes, great explanations but that still doesn't answer the BIG question I have in mind. That question is: "Then how do you explain why they even put/use alternators in gas powered cars!? They find it worth it. Why? And why, at least for electric accessories like a car AM/FM radio, wouldn't it be worth it for electric cars as well (with only the way the same basic type of vehicle is powered being different)?"
electric motors use next to no power to turn motors, ever see how small the battery is to turn the motor on a hybrid? not much bigger than a battery for a Power Wheels kids car and the crank amps arent as high. With traditional motors they need spark, unless it's a diesel, to ignite the fuel which can't happen without a big amp battery. If you make a lot of stops and have to start and stop the motor it puts a strain on the battery and it eventually dies. That's where alternators come in, while it may not be effective with multiple motor stop/start cycles-nor will the starter motor last as long- it prolongs the life of the battery until it's internal design is wore out. Most V8s need 750-1000 crank amps or CA. CCA is cold crank amps which comes in play for regions where it gets close to freezing obviously and that's why it's also listed on the battery. When the starter motor is powered by the battery using 12v it uses a small motor and gear assembly with a Bendix actuator and wound magnet to push that little gear to mesh with the HUGE flywheel...little gear moving a huge gear that mechanically turns the vehicle motor until fuel takes over. The time before fuel takes over, which also type of fuel, age of motor, efficiency, etc come into play before it takes over uses a lot of power and this being amps. the alternator is designed to take some of the motor power to replenish the battery close to capacity as long as the system is complete and the battery can accept it. Corrosion will inhibit and make that system work very hard and destroy it over time. Bigger motors need bigger alternators and higher CA capacity batteries because of the little gear to big flywheel ratio like he used in the video, it's a trade off.

@@krystoffersprague6100 this doesn't tell me anything I don't already know. My point is, even with friction of the alternator belt, they find it worth using an alternator on a gas powered car to charge the battery. An alternator is a belt driven generator.
@@kevine9376 true but it's taking too much power that the electric vehicle can better use to go further, based upon the video presentation. Now maybe if different ratio gears were used to the alternator and is took less revs to generate more current but with a bigger amp system it could compensate but again most electric batteries are massive. Even if it was a tickle, it'd still take more energy to attempt that tickle than to go further...unless breakthroughs in tech allow it to happen. It could be hidden purposely though.....
not going to lie, I clicked this video hoping to see this work, but I'm surprised how informative and educational this was! Thank you so much for sharing!
I tried to explain this to my kids but they never believed me.
I was a mechanic and I’m also a Ham Operator, both these fields use everything that you are teaching. I also tried to tell them that math drives almost everything. Now that they are in there mid to late 30’s they think they have stumbled on a fact that has been a mathematical reality forever.
Thank you Jeremy for this video. We need more people like you in the world!
so, if you whip your kids, you get more kid power interesting🤣
A shame we have so few teachers like you. You have simplified a complicated concept to the point a non engineer could understand what you are saying
speak for yourself...I may need to watch this a few times....lol
Great perspective on how you approach the challenges you recieved. The greatest tool against misinformation is education and critical thinking.
And kindness too!
Testing this so openly also displayed a willingness to be "wrong" (in the case of engineering, "wrong" just points to a need to change plans.
So true, and it's the lack of education and critical thinking skills that fuels the growing communities that hold conspiracy theories to be true (science, political, medical...etc.).
@@goodcat1982 That's true. People make outrageous claims, people click to what some nut is talking about and the nut gets paid.

😂😂😂😂😂
You have a very special talent for explaining a complex subject that anyone with a bit of common sense can understand while keeping one's attention. I sure wish there were more folks like you among us.
This shouldn't be complex to anybody lmao.
I agree that he has a talent for explaining the subject, but I disagree that this is a complex subject. It's a lot like buying something with sales tax. Sales tax representing the waste energy. You have $10, you want to buy a $1, and there's 10% sales tax, so it's going to cost you a total of $1.10. Now you have $8.90, not $10.
Then for plugging the alternator into the battery to charge it, you haven't opened the soda and want to return it. Well there's a 10% restocking fee. So you're only going to get back $1.10 minus the 10% restocking fee, which ends up being $0.11. So now you've spent $1.10 and gotten back $0.99. So instead of starting with $10 and having $10 despite returning the soda, now you're 11 cents short, so you have $9.89. You've lost money just by trying to get your money back for an unused product.
Keep doing that, keep buying and returning the soda because we're talking about an engine running an alternator, every moment of time it loses energy, so to extend the analogy to this, you have to be constantly buying and returning the soda every nanosecond. Before you know it, you're out of money. So the motor is going to grind to a halt.
Finally lol as someone that went to school for electronics, I understood right away why an alternator on an electric car was a pointless idea lol. NOW I have a video I can link to the people I argue with that will actually TEACH them once and for all lol.
As a person who LOVES a honest, educated, truly knowledgeable Teacher--- LOVE YOU Jeremy... Excellent video!!!

WOW !!! if Jeremy had been my teacher in school i could have become anything. i was never able to stay interested for long periods in these subjects you have a talent to make things interesting. gifted to teach.
Hell yeah. I reckon he could delve into & explain the chemistry/physics in EVERY episode of MacGyver...
I had the same thought when I started watching him.
Serious question. I get what you’re saying, but isn’t the variable gravity and drag? And therefore magnetic fields are the solution in some way, shape or form? Our planet oscillates in a cycle… what put that in motion, what keeps that in motion? Perpetual motion is real, we just haven’t figured it out.
Great video though!!!

I was fortunate enough to have had not one, but two wonderful electronics teachers in high school (Thank you ever so much Mr. Wright - RIP, and Mr. Conway of Westside Skills Center in Balto.

Bravo! Guys like you deserve a reward for putting content like this out there making science easier for people to understand. If think Force is quantitative then you've saved this world a tremendous amount by producing this video and many of us thank you for that
Jeremy, it is refreshing to see someone on RUclips who has such a clear understanding of physics and can explain the concepts so well. I liked the illustration of work and power using your kids to carry bricks. I especially liked it when you suddenly appeared on screen trying to "motivate" them to increase their power output. Your transfer of "power" from one plastic cup to another was an excellent way to illustrate losses of energy when going from one device to another. You are an excellent teacher. Thanks for this great video.
When I was at school, I learned 'energy cannot be gained nor lost, only converted' and 'nothing is 100% efficient'. Knowing these two facts debunks most of these perpetual/free energy type things within moments.

I really enjoyed this video. I’m one of those people who thinks ‘just add a bigger alternator’ but know deep down it isn’t that simple. The demonstrations shown here show in a visual way what scientists and mathematicians see through equations on paper, and it’s really helped me to understand exactly why ‘just adding bigger things’ will never work.

Everything Paul just said..... +1
As a science teacher at a local high school, I’m thrilled that you’re showing the answer with real science!!!!! You rock!!! 😊😊😊😊
real science is about experimentation not just talking
A science teacher interested in real science?
Is this real?
I Would really like to know how to calculate how much is lost in each conversion of chemically generated (or would that be converted from what its stored in? Like gas, coal, nuclear?) required to get the energy generated/converted so much more efficiently than could ever be done in the engins under the hood of my car before its finally the electrical energy stored in batteries in an electric car being generated/converted into the mechanical energy required to turn the wheels of that car.
So many steps must result in massive loss. From stepping (transforming?) It to high voltage, or even dc to transmit it from the power plant miles away where it is somehow magically created with ZERO emissions,
Then converted to lower voltage & back from DC to ac at my city's substation so it can fit in my citys lines to be carried close to my home where it must be transformed to yet lower voltage before into my smart meter, then into the car charger Newsome was just a couple of weeks ago was telling everyone not to use because we had a couple of warm afternoons ,
& pg&e shuts off the power every time the wind blows & the grid can't provide what's needed now ,
Because those who have now made gasoline illegal in a couple years (Right about the time Claus has declared we will own nothing. But none of all this is related, of course) they had a duty(an important word to define) to qt least maintain the grid, & If they are going to make laws requiring 5 TIMES the current load (pun not intended) on the grid they had a DUTY to ensure they improve the grid accordingly. & the people have a duty to hold them accountable for being derilect!
But I digress.
So 240vac entered into the home & must be converted to 12 vdc (=LOSS yet again. Is that the 13th loss now? Ive loss track.) to go into the batteries, to be converted into chemical energy to be stored in those batteries where it must be converted back from chemical to electric energy before it can be converted to mechanical energy to turn the wheels.
If only ten conversions/transformations (& rhere are far more) & you "only" lose 10% each time.... when fact is more like 30% loss...must be converted be used
im not book smart i stoped careing in the 4th grade and even i learned about friction do they not teach these things ?my son grade a student dosent understand fluid dynamics this is concerning to be honest
" Would really like to know how to calculate how much is lost in each conversion of chemically generated (or would that be converted from what its stored in? Like gas, coal, nuclear?) required to get the energy generated/converted so much more efficiently than could ever be done in the engins under the hood of my car before its finally the electrical energy stored in batteries in an electric car being generated/converted into the mechanical energy required to turn the wheels of that car."
The fuel you burn in your car has also gone through a series of conversions and transportation in order to become gasoline in your tank. It has to be extracted, transported to a refinery, refined, transported to storage, put in a delivery truck, added to a storage tank at your local gas station, and then dispensed into your tank. Each of those also takes energy (particularly the refinery bit, but the transport bits can also be pretty costly). Then your gasoline engine is about 20-35% efficient at turning the energy stored in the gasoline into motion.
In order to compare that with electricity, you have to really look at the exact source of electricity. Taking natural gas, the extraction process is about as energy intensive as oil extraction, but it doesn't need refining, and converting it to electricity is about 45-57% efficient. From there transporting electricity happens over wires and while it is not lossless, it involves far less loss than trucking liquids. Once it is in your car (charging is another loss, but in the 5% range or less), the car itself is pretty close to 100% efficient at turning the electricity into motion. Of course, there are some losses for heating when it's very cold out, but the gasoline car is better at that only because there is so much waste heat it can be "thrown away" into the cabin - an electric car only has a fraction of those losses when it needs to produce heat.
Electricity can also come from many sources, as electric cars don't care how their power was created - it's all electricity. So you can burn coal, burn natural gas, generate it with solar, tidal, nuclear, wind, or any one of a number of sources. So you can use the source that makes sense locally to generate electricity.
"& pg&e shuts off the power every time the wind blows & the grid can't provide what's needed now ,"
Electric vehicles can (in large part) be charged at times when the demand is lowest and the supply is highest. Other electric uses have a more difficult time moving. So EVs can provide demand when the grid has excess supply (in most places this is at night when businesses are shut down, but in areas with a lot of solar power this can actually be during the day when solar plants are cranking out power). Most if not all EVs can easily be programmed to only charge when demand is low - and if you set electric prices appropriately (Time of Use plans) your EV drivers are going to be the portion of your demand that is the most easily-moved.

THE WRITTEN, OFFICIAL PURPOSE OF SCHOOL IS INDOCTRONATION!
It is NOT Education.
If you have a child in school, you got huge reasons to be concerned. Huge reasons.
Find out what they are teaching (& not teaching) your child. Ask for a written copy of the curriculum. If they try to tell you no, think about why they wouldn't want you to know that. Could it be that you might not like the idea of adults talking to children privately about sexual preference in kindergarden &
1st grade?
That you might not agree with elementary school children being subjected to Drag queen story hour at the school's Library?.

&these are the most formative years of your childs life. The people doing this are not stupid! They are DIABOLICAL!
For the sake of your child, & the future of our world,
PLEASE look into this.

I love that you used kids to illustrate work. That’s an amazing feat in itself.
This video is getting shared with the grandkids because you’re a great teacher and so they can learn about work (the science and the labor).
Thats what I was impressed with the most, kids working and not whining, What.
I, as well, was one of those people that never understood why they didn’t just use the tire/axle rotation to recharge the batteries on electric cars. And I may have argued that my point was valid had I not watched this video. I’m old and set in my ways so it takes good logic to sway my thinking. Thank you for this informative video…it shows you’re never too old to learn something new.

@@bryankirk3567 You we’re indeed a very lucky apprentice!
You explained this in such a simple and effective manner that anyone can understand. I love that you're teaching your kiddos all of this and involving them. It's a breath of fresh air to see a parent actually teach their kids something these days!
I get it! If you attach an alternator to a Tesla's drive train, you can drive forever as long as it's downhill.
I must be stupid.
Feels like school again.
Once you don't know what he's talking about, you start to zone out.
What is the output of kids? I couldn't figure the answer out.
@@Mr_Dopey No Dopey, that ain't it.
You would go slower, even downhill . I think?.
I learned all about this when I mounted a headlight on my bicycle as a kid. It came with a little friction generator that would run against the side of the wheel to power the headlight.
The amount of drag that tiny little generator caused was absolutely amazing. I could feel it *immediately* in how much more work I had to do to get the bike going or getting any speed with that tiny little generator spinning against the wheel.
You would quickly prefer cycling in the dark 😂
What would be more scientific would be to add a switch to the light's circuit to see how much energy is lost to just the internal friction of the dynamo with the light off versus how much more energy is is needed to when the light is switched on.
@@h8GW Exactly. The mechanical friction does not prove anything. It is all about the Lorentz force.
@@h8GW Yeah, the bearings on the bit that went against the bike tire and the dynamo were usually hot trash, but you could still feel the drag drop off just a bit when the bulb burned out. Adding a switch would still have been a useful exercise in terms of being able to repeat the drag changes many times, to be sure.
I absolutely love how well you conveyed the transfer of energy between such seemingly alien systems. I have a BS in engineering, however, while I was in high school I could not wrap my head around gears, teeth, size ratios, and efficency transfers. Watching this, I truly wish I could have had these kinds of videos available. I have such appreciation for people who take the time to explain, in such a concise manner, things like equivalent exchange. Hope to see more videos like this as opposed to others trying to disprove the earth is round.
This video is underrated. The way everything is explained is simple and straightforward.
I wish I had math and science teachers like you back when I was in school. You have amazingly explained this concept.

Great video. I love how patiently and respectfully you answered the question.
Jeremy….you are so 1000% correct! People have been trying to create perpetual power systems for many years. But until you somehow reduce your system resistive losses to zero….you’ll never get there. The conservation of mass and energy is absolute!
I'm a process/ manufacturing engineer with a degree in mechanical engineering so this is basic for me but I still enjoy watching these video teaching the fundamental of physics in an engaging way to future generations. Teachers like this are one of the big reason why I was so interested in engineering when I was young. Good job sir!
I’m not an engineer so I’ll ask my dumb question. Say you build a light weight alternator that didn’t take a lot of torque to turn. Could you turn it sideways and add a pinwheel on the end of the shaft, then have a wind funnel on the car so it charges when you drive 35 MPH or faster? Obviously this isn’t going to do away with the need to charge but if you build one into each side of the car with intakes and one on the roof it might in theory be able to drastically extend the time needed between charges right? I work in green energy so I was just trying to think outside the box and can’t find an obvious downside to this. What do you think?
@Dustin Bridges The main issue, if you were to do this, would be the added drag from the wind generator/ wind turbine. Especially, for an EV, drag has a huge effect on their efficiency. I haven't done the math on this but I am willing to bet that the increase in air resistance, turning the fan, would out way the energy generated. The only time it would generate more energy than the car is using is when it's going downhill but by that point, you should just use the motors driving the wheels as generators which all EVs do use (regen braking). Hope this answers your question :)
@@ValidAsian thanks

May I ask if that is the engineering job you wanted? Or did you have other fields of engineering you were interested in? I always wonder what people want to do with mechanical engineering and have a hard time myself figuring out what I'd want.

As an older and now-retired mechanical engineer, I must say that your explanations and demonstrations were spot on and excellent. Great job!
Such a fantastic video! Thank you so much for sharing. I sympathize with you about how people persistently seek a perpetual motion machine, continually asking questions as if there might be a magical way for one to work. As a Mechanical Engineer, I remember my professors discussing many of the topics you covered. You simplified some of these concepts in marvelous ways that I've never seen before. It was a very enjoyable video. I've been trying to explain torque, power, and work to a close friend in relation to a bicycle and a manual transmission, and I think this video will be very helpful.
Love the way that you break down your explanation of things, and offer a few different ways to explain your point. Informative, not condescending, thorough and easy to follow. Thanks for creating videos that are actually enjoyable to watch.
This reminds me of working on stuff with my dad teaching me stuff while doing yard work. I grew up to be an engineer. What a great video, and I know your kids will look back at how great it was to have a parent teach them all this stuff.
I love content like this. Science based, friendly and forced child labor. =)
So true. You can't move bricks faster by having more kids, because making more kids requires more energy, time and money
If you are a teacher your student are soooo lucky. You are an outstanding communicator. 🙏
When it comes to engineering, math, physics, and related subjects I end up with a glazed look and understand nothing. I admire people who can understand and use them to solve practical problems or explain why it can't be done. You explain the basics clearly, instead of trying to make yourself sound brilliant. I envy your children and students for their wonderful opportunity to learn from a true teacher. Thank you.
I have a small crank-powered light. I discovered years ago that it is much easier to crank with the lamp turned off than with it on. The misconception about alternators seems to be "it's already spinning" without taking resistance/load into account. I found my light was the perfect demonstration of this fact.
Thank you Jeremy for taking the time to make this extremely helpful video. As a father of 5 (all boys except for the first 4), I understand that in order for you to make this happen requires a family effort. Again, thank you and your family.
lmao
Great video. I already knew the idea was bogus, and using regen braking is basically the same as adding an alternator. Mostly I clicked and watched because I was curious as to how someone else would explain this. You made it so easy and simple, anyone could understand. Great work.
Thank you for your video. I'm over 70 and when I was a freshman, I came up with the idea of hooking a generator to a motor so that the motor would run forever. My science teacher walked me through the reasons it wouldn't work. I finally believed him when we set up a test in the lab and the motor stopped turning almost immediately. We spent a week of lunchtime breaks investigating why until I finally got the fact that energy is a constant and can not be created or destroyed. I fell in love with math after that experiment and went on to spend my working life as an engineer. My only regret today is that I have forgotten his name but not the time and the love for science he gave me..
Great story
Thank you
you honor what he taught you, which is better then remembering his name, imo
i would rather people remember the contribution and effort i put in, then my name or the color of my hair/eyes, so i wouldn't feel bad at all, the man loved what he did and passed that on to you, and hopefully other students :)
Your kids are blessed to have you as a father and teacher sir.
Agree, Those are some lucky kids, their Dad is wicked cool.
Unexpected analogy, but I loved hearing the splash every time the power shifted. Bonus points for addressing regenerative braking. Great video!
I first read of regenerative braking in a very early copy of Mother Earth. It was a hydraulic based system. At the time I thought that the author had not allowed the added weight of needed pumps and such. A few years ago driving a nephews Tesla S for the first time, I was shocked at coming up 20 feet short at my first stop sign due to for the regenerative braking.
You are a very generous man Jeremy. Thanks for taking the time and having the patience to help us.
I thought this stuff was possible when I was younger. Eventually I understood that with the very basic laws of physics, none of this is possible, especially perpetual motion.
But I really love the way you have explained things, and I will use some of your analogies, when trying to explain to mates why these amazing things they have seen on RUclips just aren't possible😂
My first time seeing your videos. Absolutely wonderful! I'm a fan now. In a world of "alternative facts" nonsense, your low-key, rational, logical videos serve a much broader purpose. Thanks!
Using the cups with water was a great visual, really helps visualize and explain the process in simple terms that pretty much anyone can understand. Really wish I had teachers like this when I was in school. Then I might have actually paid attention. Thanks for sharing.
Edit: One thing people should take away from this, is that if it were this simple. It would be common place on every EV. I had a coworker say they should put turbines on EVs to help recharge the battery while driving.
Reminds me of a lady who doesn't quite understand why they can't put a wind turbine on a car for the same reason.
Most EV's do have this... its called REGEN ....its used to slow your car and put power back in the batteries...
Yes, it would have been nice if he could have caught that "spilled" water and funneled it in to cups labeled heat, friction, light, resistance...

You are spot on. I am an Auto Electrician. Based in the UK. and when a customer would come in. Because their belt a squealing. I try to tell them that they. Probably have just started the engine. And the battery has used some of its power. And it’s asking the alternator to put mor power output. Basically the alternator pulley is resisting the rotation, it wants to stop or turn in the opposite direction of the engine. Which is why the belt is squealing. Because under total load. A large output alternator would take up to roughly 5 HP to drive it. The same if your engine is idling. And you turn on the AC. You will see your rev-counter will lower. Momentarily. Because of the load it takes to run your Air Conditioner. On an older car the revs will slow down and stay there. Modern cars. The ECU will command the engine to raise the revs back to the original idle speed. Apologies for making a simple explanation. Be this long, but it is the same principle as you explained. Everything takes powers to turn the pulleys. I hope that all makes sense.
Very impressive explanations. This grandma, with no college, did not get lost. You had me at "you cannot create or destroy energy, you can only change form." You've taken Einstein and given us a hands on demonstration that brings that reality home. Thank you Jeremy!
Best explanation of why an alternator isn't a free energy machine. I've tried to tell someone this but i am not a good talker like this guy.
The laws of thermodynamics stops this from happening. Also the laws of conservation of energy. It can be done in an environment free from these laws. Some kind of vacuum or something.

I smile every time I watch you break down things that I understand but, can't put into words. You're a genius and greatly appreciated. Keep up the good work! And thanks for sharing.
Long Live the Fieldings!!
Bro, if I had someone like you teaching me in school 40 years ago, I most likely would have grasped all of this knowledge far better than I did. I was in a private church school k-12 and never had teachers. The help were parents who donated time to monitor the students, but anytime I needed help, I was told to figure it out. Well, if I could figure it out on my own, I wouldn’t be asking for help.
I have zero regrets in how my life has turned out, but I watch videos like this in hopes to gain more applicable knowledge of how things work. I appreciate you breaking this down as much as you have.
Amen great job
Hey Jeremy, 1st time viewing your video. Thumbs up bro! exposing the fake and shares real knowledge with your viewers. Keep up the good work.
"More power to you brother. I'm gonna teach my kids about the laws of physics" :-) Thanks Jeremy. You fixed thousands of minds.
Seven minutes in and I think i see where this is going. You are a very good teacher! Thank you for sharing your knowledge!
I have no idea how I ended up on this video, but I am so glad I did! You have a fantastic way of explaining things and I enjoy your method of teaching! Cheers!
I can tell your parenting skills are impeccable...😎 It don't get much better than this....
Excellent program Jeremy. I taught Basic Electronics in my days in the Navy at Great Lakes. I was watching and remembering students asking these same questions. I am glad your channel makes it clear and concise.
