This is amazing and simple. Is it free energy? Can it be set up to gain energy?
@wobblyboost you're not understanding the laws of thermo-dynamics, even if it's "free as in free beers", it takes energy to generate beer, and that energy can't generate "more energy", you can only lose energy in the process even if it's only a tiny amount. But it's youtube and clickbait is what makes more clicks/$$$ so it's a bit disapointing to see Integza follow that "unmentioned rule of youtube" as his content was already interesting enough to generate clicks.

Integza: I can explain it better than you
Veritasium: * 4 hours later * here's another video explaining it better
Bwahaahahahahahah
Funnily enough, this video is still better. How pitch and a propeller works are both better explained.
@@Klarinet2011 Certainly useful explanation. That said, better engineering by Xyla Foxlin, and with some last minute adjustments, they made it work.
Yeah I still don’t get it even after watching Derek, Xyla, and Integza. I liked this video a lot but it never demonstrated the car moving faster than the wind and what the upper limit would be. However it also taught me not to buy a 3D printer lest I become an addict, so thanks for that ;) Clearly it involves sails so I need a pirate hat and rum and paper and pencil!
@@Archpimp because there is a difference in speed between the air and the ground, there is potential energy.
That energy can be captured and used if you are standing still, that energy can be used if you are moving. That energy differential has nothing to do with your speed relative to the air or the ground.
If you make a small enough, efficient eniugh system, and you capture enough of the energy, you can divert enough power from the differential in the wind and ground to move a craft.
Speed doesn't matter. And thus, if your system is efficient enough and your collection large enough, you can move through the air at a higher speed
The reason your car got a 1:1 rotation between the propeller and the wheels is because your gears at the front were a different ratio. This is also why you had some issues with the first propeller not moving very much. If you do a 3:1 ratio or something it might move easier with the first propeller
I understood the explanation about halfway through because i knew dereks explanation, and thenwhen you finished the whole wind exanation i finally realised that the wind can push the vehicle up to windspeed and then the ground is moving backwards at windspeed relative to the car, allowing you to exploit thatby using gear ratios for minimal drag. Dereks old explanation, new explanation, and integza's explanation all came together for an intuitive explanation in my mind.

Here after Derek's video about the bet. Maybe you can add some thoughts on this debate, especially considering he also made a 3D model available from his testing.
same
I got the notifications for both videos. Unfortunately, Derek's was first. Haha! Integza missed a 10k bet...
I think so far Derek's simple cart with big wheel on top and smaller ones at the bottom best illustrated how a vehicle can go faster than the medium pushing it. The wind adds extra complexity in that the coupling with that medium using the propeller is not as simple as in the cart example, but the basic concept is the same.
@@MisterkeTube yeah, I agree. The three-wheeled cart illustration is what allowed me to finally comprehend what was going on
@@MisterkeTube The funny thing is we all probably would have played with or built a similar setup , especially if a person was into LEGO. Just how that principle is applied for the wind car is extremely clever.

I’m sure you tried your best, but by adding the fan you broke the experiment. The whole point of using a treadmill is to move the ground instead of the air, so if the car moves in the opposite direction of the treadmill it moves faster than the wind, since the air is stationary. By adding the fan, you had to make sure that the car moved faster than the wind of the fan. Unfortunately it clearly didn’t move faster than the wind of the fan. You can see this because the string attached to the frame went forward instead of backwards. So unfortunately the was too much friction in the gears or the propellor wasn’t optimal.
I agree, it's all in looking at the tail-tell on the car
“As long as there is no ridiculous amount of friction”.
His words as he is showing the car with the fan… He is speaking to his more enlightened viewers. The ones who understand what he is getting at. For some reason you didn’t catch the not at all subtle explanation that his design OBVIOUSLY has a TON of friction because DUB just look at it! I don’t even think he uses metal on metal bushings let alone bearings, getting the gear ratios correct, getting the blade profile perfect…
He doesn’t have to do those things because 2 people have already done it and as a pre-requisite for you commenting on this video you had to have watched the other video that try’s to explain how this car works that DOES have a working scale model on a treadmill.
So he isn’t responsible for making a working scale model…
He said he is just trying to explain it differently.
Because even though for me the first time I watched the first guy explain it I was like oh shit duh… why don’t people understand that theoretically this makes perfect sense and someone has already shown it working at scale and in reality.
This guy doesn’t need to show it working again…
I love it when the RUclipsrs I watch watch the RUclipsrs I watch, hearing about it always just gives me a little spark of joy.

If done right, you can accelerate the car on a treadmill with no fan or wind at all. Just the wind produced by the propeller can be enough to make the car go faster than the treadmill is spinning
video idea: design and print vehicle (thats fly or just drives on the ground) which will be powered by one of yours jet engines, i'll be pleased to see that.

0:53 "Sounds like Mikey takin a leak."
The way i understand it is that you have 3 points of reference: Wind, ground, vehicle. Drag (wind-vehicle) will accelerate the vehicle against the ground. In turning the wheels and turning the propeller you put additional air in between the vehicle and the wind, adding more momentum. So it's basically like an afterburner. Like an additional cushion you propel yourself against from. It's not a vacuum after all.

W==> P
Max speed is reached when W => P,V

@@GhostRyderFPV ok
How about if the gear ratio of the prop to the wheels were higher? Wouldn't that allow it move with less wind?
If you have rc transmitter and receiver which you don't need anymore I will be more than happy to receive them
How can you be so creative and at the same time have respect for a televangelist like Peterson.
Because he is smart, and Peterson is smart. And smart people like to listen to other smart people.
and for the people wondering how it can accelerate more and more on the treadmill, yes its possible but the energy comes from the treadmill motor itself. the propeller connected to the wheels causes the wheels to require a higher force to spin which slows the treadmill down but the treadmill motor counteracts this slowdown. so the energy in that case comes from the treadmill motor! cool right?
the timing of this video is like u have insider info
Video Idea:Please make a linear airflow chamber and test an airfoil for maximum optimisation. I think till now nobody has created a small airflow chamber, Petersripol tried but failed at last. I am a mechanical engineering student and a 3d printer will be very helpful to me.
When one of these vehicles is working right, it will actually travel straight into the wind, as seen in several other videos. That would be a much more impressive thing to show.
By adding the fan you've increased the relative speed of the "wind" to threadmill + fan, so the car has to go forward faster than the fans wind, on a threadmill. That's the whole point of the threadmill. With your setup even a wheel will go faster than the threadmill with sufficiently fast fan. Boo.
The design is still very much possible, but yeah you need to measure the air speed and add it all up to prove integza's model works.
You are mistaken. The whole point of threadmills is to mill threads.

I watched both of Veritasium's videos on this, as well as Steve Mould's, and I still couldn't wrap my brain around the effect. In this video though, YOU finally broke it down in a way that something clicked and I now can understand what's going on.
The propeller is BACKWARDS; the wind would normally spin it in it's natural direction, but the prop is mechanically geared/attached to the wheels in this backward orientation. When the wind blows, rather than working to spin the prop, it instead just PUSHES the whole vehicle contraption forward (just like any object in the wind would move forward, as long as friction is forgiving enough).
As the wind pushes, the car is rolling forward and the wheels are turning, which then spins the prop in the BACKWARDS orientation. Because the prop is spinning backwards, it continues to act as an efficient sail, and the wind keeps pushing the car forward until vehicle speed matches air speed (minus friction?).
However, because of the special propeller shape, with enough speed, the prop eventually ALSO starts doing ITS job, of making a high and low pressure pocket. Because it's now spinning, while the whole car is also still being pushed forward by the wind, we now have two methods of thrust rather than one, overcoming the speed of just the wind sail on it's own.
As long as the vehicle is designed in such a way that friction is low and propeller thrust is high, the outcome is an acceleration vector in the direction of the wind, larger than that of the wind itself. I think I get it!! 😊 In my opinion, Integza, you've won this one!
The only thing I will say that Veritasium did do better was the model car. He continued to work on the design (with the help of a friend) to eventually get the car to a point where it CAN drive faster than the treadmill, without the need for a fan as additional force. Because you used a fan AND a powered treadmill, that's definitely cheating and does not actually demonstrate or prove the point you're trying to make, so the example is a little lost/nullified... That's okay though! Your easy-to-understand explaination made up for it 😊😊 Thanks for your fantastic and educational videos, Integza! ♥
it seems to me that it would make more sense and perhaps be safer to put the prop on the front side of the vehicle. And instead of one large prop. put one on each side of the front of the vehicle. and put a pivot on them that would allow the prop to rotate to be perpendicular to the wind from whatever direction it is coming from. I would also try with a 3 or even 4 blade prop.. or perhaps even use a prop that spins perpendicular to the ground.. which has the ability to catch wind from any direction (360 degrees). When i get my 3d printer i might make one and put video of my design on youtube.
@@manp1039 That would be awesome! I would love to see it.
3D modelling isn't boring, that's the craziest thing I've heard today and I just got off the phone to my brother.
Hey Integza, I bet you £10k that you're wro... nah actually, you're good.
Lol, that video was good. Kudos to the prof for admitting defeat though
@@halsoy he admitted defeat, but he still claims he was mostly right and we are mostly wrong. Which is, as we scientists say, bullshit.
This did help me understand it better than Veritasium! Thanks!
You're mixing two frames of reference here.
To use the threadmill example, where the car is moving forward in the air with the ground moving backwards underneath it:
- The wheels drive the propeller
- The propeller accelerates the air backwards, creating thrust.
Now let's move our perspective to the ground being stationary and the air and car moving in the same direction:
- The wheels drive the propeller (same same)
- The propeller slows down the wind behind it, creating a low-speed area behind it. This is where the energy comes from to go faster than the wind.
Say the airspeed is 20 kph and the propeller accelerates it with 15 kph in the opposite direction. The resulting airspeed is still forward, but at 20-15=5 kph.
It's a wonderful almost counter-intuitive system, but once you grasp it it's simple and elegant.
"The Dark Arts of Trigonometry!"
Me: "Dark Arts is putting it kindly."
Also I want to add my thoughts. Even a Sail boat that is Tacking in the wind at the optimal angle has an absolute limit beyond the speed of the wind. For the very same conclusion you came to. The low pressure in front of the sail pulling it faster than the wind behind the same sail eventually equalizes because of the on coming air pressure.
You could do this same experiment on water by replacing the Sail with a big wind blade that's tied to a Prop under water(if you didn't couple it to an under water prop the Wind blade would just pin wheel).
But at the optimal angle it won’t be going directly down wind it’s going partly sideways. so it can be going much faster then the wind would be able to still propel the boat even when it’s going faster then the wind
Veritasium just did a $10K bet on this exact subject, you guys need to see it
I'm sorry, but Derek uploaded around the same time and he explained it better. ;D
For the video idea: You've already built a Stirling engine and we know that it turns a difference in heat into rotational energy. From what I heard, this process is reversible. So add a motor to the Stirling engine and see if you can improve the design to create a heat pump and generate a noticeable heat difference. Bonus points if it can actually be used to cool something.
The finger on the glass was actually a darn good analogy.
The ads tricked me for a second. Right after you said "3D print a car" an image of a Pizza appeared and it took me a little while that it was an ad and not your brilliant car design :)
Treadmill + fan is invalid configuration for testing this - it makes the wind speed be relative to the vehicle, not the ground it is supposed to. It effectively adds speed of the treadmill to the speed of wind
It's force x distance of the rotor vs. force x distance of the wheels minus various efficiency losses. The issue is the conversion of a rotational distance to a linear one and any mechanical advantage that could be used to convert applied force into additional distance on the output end. It should go faster until the force needed to have the cart move forward via the wheels is less than the force available to the turning rotor. Add in the time factor and it's power-in minus losses equals power-out.
Theres one experiment I've wanted to do for years. Pneumatically spinning a low temp liquid metal, and then running current through it. Inside of a glass container would be ideal, and my thought is using gallium or mercury. I just want to see what a magnetic field vortex might look like. Please, not even for the printer I really just want someone to do this.
I'm fairly certain I seen someone make mercury spin with magnetically induced current on youtube.
Cody's lab makes mercury motors all the time.
mercury is harmful and gallium is furiously expensive (and these are the only options of fluid metals in low temperatures)
@@wojciechsosna9230 Mercury is practically harmless unless it makes contact with an open wound. If you wear gloves it's safer than many chemicals that are used in chemistry. It can't even get into our bloodstream through mucous membranes like other chemicals because the surface tension is so high.
Here's an idea, because low temp is fairly relative, research some other metals that have lower temperatures. 2 other points of relevant data would be their conductivity and magnetism. Some other things to check out, glass temperature and what kind of motion will elevate the viscosity, if magnetism can influence viscosity, or electricity. Glass temperature is the point where a material becomes a gel like consistency. Actual glass can take some fairly high heat before deforming.
I think the clearest explanation of how the car works is Veritasium's animation of the sailboat traveling on the cylindrical world, but I enjoyed your video for the slow motion run into the tomato.
The air pocket is like a cvt transmission because as speed increases there’s more and more of an air pocket for the wind to push on

Video Idea : trust vectoring jet engine
Basically, the car's blades act as a sail surface. When said sail surface is also moving, the speeds are compounded. This, the speed of said object becomes faster than the air pushing it. If you check the windspeed of the fan at it's output, it should be greater than the speed of the air pushing it.

But take a few days to make a video like this.... its more just bad luck and coincidence that Veritasium posted a lot better video 1 day after this one.
@@brianfhunter I’m not sure we understand each other.
i think a sail boat goes faster than the wind into the wind, because the sailor adjusts the sail to be in the shape of an aerofoil and the created lift pulls the boat forward
You should watch Xyla Foxlin's video on her channel! She was the builder for the model in Veritasium's video.
What you missed is the diameter of the wheel! The ratio needs to be about 4.5-5:1 propeller diameter to wheel diameter.
So basically, just put bigger wheels on it and it won't need the fan to help it!
Bottom line - the point is the fact that the propellor connected to the wheels. The wind will take the car close to wind speed - then the prop basically do the addition - you can say trigo or you can say branuli.
Now Im curious to make mathematical expression to calculate the equalibriume of the system and to extract the max velocity... If you have this I will agree that you got it.

In the case of thin airfoils (sailboat, hang glider), the air flows the same distance over and under the airfoil. The flow under an air foil is essentially pushed down, and the air flow over an airfoil tends to follow a convex shape (up to a point, if the speed and/or curvature of flow is too much, vortices form, reducing lift and increasing drag), due to viscosity and to avoid creating what would otherwise be a void, reducing pressure. Faster air flow coexists with the lower pressure just above the upper surface of a wing, and slower air flow with the higher pressure just below a wind.
As for DDWFTTW carts, a propeller is used because it is efficient, not because of its resemblance to a tacking sail. For example, consider a model river boat driven by a paddle wheel. The paddle wheel is driven by two spools being turned by wires being unwound from the spools by being pulled backwards, geared so that the wires move much faster than the paddle wheel. If the wires were attached to two posts in a stream, the boat would move downstream faster than the stream, with nothing resembling the tacking aspect of a sail. The key factor for the boat and DDWFTTW carts is an effective reduction in gearing, so that a higher speed, lower force is geared down to result in a lower speed, higher force. For example, assume there is a 10 mph wind, and a DDWFTTW cart moving downwind at 15 mph. From the cart's frame of reference, the ground is moving at -15 mph, and the air is moving at -5 mph, 3 times as slow as the ground. This would allow the speed from the ground to be divided by 3 and the force from the ground multiplied by 3 before losses are taken into account. Perhaps after losses, the force is multiplied by 1.5, which is still enough to cause the cart to accelerate faster. For your model, its most likely that the pitch of the propeller is too large. With a smaller pitch and larger diameter propeller, the speed of the thrust is reduced, but the force of the thrust is increased. That was the issue with Xyla Foxlin's model (too much pitch, reducing pitch and increasing propeller diameter solved the problem).
You have the best mix of comedy and science that is only rivaled by Electroboom.
Have you ever experimented with the Magnus effect?
For those that are unsure of what this is, here is a simple demonstration:
1: Take the insides out of a Bic ball point pen (the kind that is just a straight, un-tapered cylinder works best)
2: Place the cylinder on the edge of a surface that is off the ground.
3: Place 3 fingers from each hand on the cylinder slightly closer to you than the center of the cylinder.
4: Push down with your fingers evenly until the cylinder "pops" free from your fingers.
This should create backspin on the cylinder and forward momentum which, if done right, will cause the cylinder to lift or float as it moves forward.

8:43 He asks hurricane Katrina to go faster? Bold move! But I did expect nothing less of Integza, of course.
The way that the fan moves the car is the same way that the fan wants to stop the blades
Add one more thing: fixed propeller has drag almost equal to drag of propeller's projection, but spinning propeller has drag equal to 8/10 of a circle it spins in. That is how autogyros works - those flying machines has angled propeller that acts like a huge round perforated wing when spinning. And it also has airfoil in addition to that.
Create a rocket powered autogyro with 10 small rockets lighted one after another.
video idea: make a CVT transmission and test with your engines and use to make vehicles or maybe throw a tomato on it while running >:)
Oh gosh I would love to see homemade CVTs so much!!
I think you need to use the prop backwards, as a tractor, you rely too much on the fan blowing on it, it should have enough momentum with the treadmill and the wheels to gears, it should work.
Look at it as a matter of energy,
Putting aside wind speed, it's pushing with a force, with bigger propellers, car gathers more force, and with propellers configuration set to resist the wind, the extra power translates to more speed
Like a pulley transferring power to speed.
The propeler on the sail car is not connected to the wheels, the belts coming down from the propeler are for pitch control alone.
It's definitely connected, if it was freely spinning, the wind would turn it the other way.
It is connected, watch veritasiums video
@@pocarski isn't the rotation determined by which side they the thicker part of the wing is? As in...blow in a computer fan and see which way it spins...
@@iulianlazar8893 It's mostly determined by blade pitch. The sail car's propeller is rotating in a way that would push air backwards, which doesn't make sense if it's being spun by air coming from behind.
Video idea: put rocket engines on the “laws of physics breaking car” and see how fast it goes or Mach a new care with the same concept as this one but with rockets instead of wind
big fan of rockets eh?
@@CTMKD ...or a big fan of Integza...which makes one big a fan of rocket engines.
@@klausstock8020 yeah that checks out too
For you next rocket engine, try the ARC heater. Heat up compressed gas using an electric arc and then expanding it through a nozzle.
We built a propeller to power a small pump in class because we were being taught about wind energy and windmills. My friends and I decided to 3d print a propeller with a semi-optimized profile. On our first test the propeller worked too well. It was so fast it moved the gears in the gearbox which disconnected it from the pump and made it spin freely. One of out propeller blades got launched into the ceiling and another almost hit one of out classmate. To be fair, it was initially designed to power a two chamber pump which we had to switch to a one chamber pump because of issues with connecting two pistons to one windmill and a lack of time to fix said issues. In the end, we swapped out the gears, better secured the windmill in place and it worked perfectly. Lucky for us the two blades weren't damaged too badly and we were able to reattach them with a bit of glue.
Once again asking Joel to make a propane-powered sonic cannon to explode tomatoes
Still waiting for "DIY nuclear reactor" or "fusion reactor"
Oh man you'll destroy this world.
(3D Printed)
Me too
@@shahzadmughal7666 fusion reactors do not explode they will shut down
If anything breaks the laws of physics, the laws were already broken.
the force of the impact remains the same regardless if you run at the thrown tomato or stand still. mythbusts did an episode on this after they rammed two trucks at 50mph into eachother and stating that it would equal a 100mph crash how badly each truck was damage was indicative of each truck experiencing a 50mph crash
VIDEO IDEA: build an electric brushless motor and use it to SMASH TOMATOES! Just a lot of coils you can wind with a 3D printer!
What about building a "Compressed air cannon" which can be used to kill "Tomato Lord jr" by using his fellow tomato army or other materials .
Ye
integza, i will not let you run into a thrown tomato for nothing. have my subscription!
With Portugal leading the charge with Deltavariant corona, I suggest you make a Delta-wing jetpack. 3D printed, self-propelled flight... That's the future!
3D print a rigid Zeppelin style air ship. I don’t think it’s been done before.
INTERESTING!!!!
Very interesting. Plus, if he uses hydrogen for the lift gas there's chance for an explosion! 😁
Video Idea: Build a liquid salt nuclear reactor!
you kind of can't do that
@@yes1603 we'll see
@@blanana_m can you tell me how the 3d printed plastic won't melt?
That seems both highly expensive, rather dangerous, and potentially illegal without a permit and a degree
Nuclear energy is not something you can or should ever mess with if you don't know exactly what you are doing
nuclear physics are not something you should ever try just figuring out by messing with it, you need to be formally educated on exactly what to do and how to do it safely before you should ever touch anything to do with nuclear physics
@@yes1603 It was just a joke
Seems to me the best way to demonstrate the idea would be to make a model train that works this way. Just build the track around a turntable. When the track turns one way, the train will go together.
Using the fan worked against the intent of experiment. With the right pitch and size propeller, you may have succeeded with just the treadmill.
video idea: use large bottles and fill them with air, make a variable nozzle, attach it to the rotary engine car, and yeah my idea is to build a long lasting rc car
Tom Stanton made some videos doing this, even attempted to make a plane.
@@rdizzy1 he wrote long lasting, tom stanton made rc planes that would only last only a few seconds, his idea is to make it last longer
Just drop some dry ice in Tom's design?
@@Specter0420 lmao that works too
@@bon2183 There is a video floating around on youtube of some students that made a small human sized car that ran on tanks of pressurized air.
For the video you should make a vehicle that holds your jet engines
Also because the propeller of yours is inclined, it pushes much to the ground and increases the push downwards. Maybe if we attach the prop with the rear wheel perpendicularly and trying to make the body from light material like like carbon fibre or something else. I might be wrong but it might work.
"My propeller kicked in"
alternate title:
17 minutes and 6 seconds of Integza explaining that he is better than Veritasium
-and then failing to build his model because he still added wind onto his threadmill
Video idea: make a turbo pump for a liquid fuel rocket... and use it to smash tomatoes xD
Good idea! :D
15:50
Someone's been watching electroboom 👀
You should make bigger and stronger TurboJet Engine and strap it to an RC car
The line I most like in this channel: Tomatoes are disgusting 🍅 😂
Video idea: you’ve got that poster of Nikola Tesla… so how about you 3D print an ac generator and a mini Tesla coil to go with it?
I like this
The best way to demonstrate the concept of this car is take a spool that can roll up a string. Bend a coat hanger into an axle for the spool and a guide for string. Run the string through the guide and start it on the spool. Go to the other end and pull the string. The spool will roll up the string as it travels along the floor. Since the spool will roll up the string and catch up to you. It will obviously have traveled faster than you pulled the string.
In a sailboat you extract the energy contained in the differential between your speed and the wind speed. In a correctly tuned propeller car, you are extracting the difference between the wind speed and the ground speed no matter what the cars speed is.
