I think you over estimated the amount of steps Tesla would have taken to developing this. It is trivial to realize that forcing fluid back on itself will cause a high reduction in flow. To me it seems the first step would be to start with a series of the lobes that we see, then adjust the angles between them to be optimal, rather than what was displayed in the video. Granted, your intent may have been to demonstrate the way a modern engineer would approach the problem, which would have been fine had you not portrayed it as Tesla's design process.
I'm actually considering to use it in a work application. Could someone help? The thing is, we have a centrifugal pump with DN70 inlet, sucking fuel from a tank. But we also need to create pressure in front of it, using a specific gear pump. We tried using conventional one way valves to keep gear pump from just sending fuel through a loop, but it ends up just closing them and suffocating the centrifugal pump. Will Tesla valve work in this scenario, when you have a flow going one direction, but pressure is coming from the other one. Seems kinda impossible when put into words, but I hoope there's someone here, who can help
What happens with superfluid if you use and expansion chamber between two of those valvular conduits ? Would superfluidity prevent the turbulence or not? Some one need to test this, cause we will soon realise Space might actually be superfluid ocean in wich planet floats. An article published on September 21st 2020 from Lancaster teach us object in superfluid helium act as thought they are in a vacuum.
It is kinda common for genius scientist to work in various areas, it's just usually they impact certain field of study so much, that it overshadows their achievements in other fields, which are remarkable by themselves
@@snowblazed3442 i'm pretty sure you can't create a tesla valve equivalent with wires =v however i'm a software engineer so my knowledge in the matter might be limited
@@dtom2126 hmm so every secondary flow could be wires from a higher resistance than the ones used for the primary flow ? =o Now it actually seems plausible
The interesting thing about this apparatus is that the reduced flow from the output side is fairly consistent no matter how much pressure is on the input side. It's not adjustable but this would have applications where someone would need a relatively stable volume of liquid flow regardless of the changing input pressure. I think that is the real purpose of this valve, not so much being a one way valve.
I wonder if there’s a lower threshold whereby if the input is slow enough, the various divergences and vortices are minimised, therefore the the output would be increased compared to if you had a higher input (which would seem to create more restrictive flow?)
I think you are right. It’s a simple and robust way to meter something using higher pressures elsewhere. It really can’t stop flow because it relies on the dynamics of flow to even work.
Can you show the difference of water speed in a valve? It's an animation based on laws that are accepted. Like animating an object falling because we know gravity exists. Jesus
@@lick28 His point was that you can animate anything. You can animate the valve breaking from excess pressure. You can animate an anvil falling on it. You can animate glitter coming out of the other end. You can also animate generally accepted "laws" in the logic of children's cartoons but that does not make them real nor evidence of any kind of "laws". And yes, you can show the difference of water speed in a valve. Today we have plastics and glass to make small scale low pressure valves. We also 3D printers and pressure gauges. I am surprised that a reasonable person would suggest that the only way to demonstrate how a valve works would be through computer animations. Because we all know the significance of computer animations when Nikola Tesla made the valve in question...
@@guywiththebottle and my point is that there's no reason to make up anything false. It's also much easier to just animate something we know to be the effect of a certain action than to go out of our way to waste physical resources like water and money. It's also easier to articulate how the inner workings of something goes in an animation as you can highlight the important things to be noted. Complaining about the fact that it's animated in this context seems very nitpicky
@@lick28 There is reason to make up something false if you can get away with it or do not know better. People care about 'fake news' more than ever and everybody is the publisher on youtube. The guy asked for another reason to believe the premise of the video. If people know the effect of "a certain action", there wouldn't be a point to making the video. Is it a waste of physical resources to teach people about valves? You can highlight whatever you want in an animation, that was the point of the critique. Not sure why it would be nitpicky that the guy expresses that he would be more convinced by a recording of a stream of water rather than a simulation of a stream of water.
@@lick28 We live in 2022 and you really wanna say theres no reason to make up anything false? The dudes right, I wanted to see it for real. I dont want what he thinks will happen in an animation, I wanna see what does happen in reality.
Fluid dynamics is a very interesting and very complex field and has an impact on so many day to day things that we take for granted. Tesla was a true engineering genius.
@@laernulienlaernulienlaernu8953 That's a stupid comment. Tesla is a cult in the US and much of what's attributed to him is mythical. Whether or not I'm smarter than he was is irrelevant. The fact is that Tesla was a talented engineer but was not a physicist of any great ability. His achievements are greatly overstated and the hyperbole in this video is both incorrect and pathetic.
As a 20 year master plumber I love the design due to it not having any mechanical parts that could fail for a pressure reducing valve this would be great
Also the primary flow in tesla valve isn’t a straight line. For every section of the “bucket” structure the primary path is tilted so that it matches the entrance of the next bucket structure, so making is very effective at dividing the primary flow into a secondary flow that opposes itself
Something not mentioned in this video is that alongside the mentioned flow restrictions of the Tesla valve, after the first switchback the "main" flow will be directed towards the next switchback each time. It doesn't appear to be an even split into primary and secondary.
Actual conversation with my wife: What are you watching? Something about valves Why? I don’t really know but I want to know how it works What it’s for? I don’t even know. But I feel like I’ll know everything about valves soon.
Claiming to be a “total physics” video without demonstrating a real world model of such a simple device is a fail. The simulation software is fine but not a complete picture. Also this valve is crap under any appreciable pressure. You’d get backflow in no time. It demonstrates that it is not possible to make a true check valve without moving parts. A small ball check valve easily handles the job.
@@sircrapalot9954 Application of newer technology is much needed. A train 🚂🚋🚃🚋🚃🚋🚃in a tunnel with walls that reflect the divergent air on to the rear of the train would have twice the efficiency of trains today. Using turbo jets to clear air from the front would prevent wind resistance in the tunnel while additional forward thrust is developed. Directing this displaced jet of air on to a modified Tesla mechanism on the tunnel walls to redirect the air jet on to the rear of the train would again add forward thrust. This is significant since wind resistance at 100 mph is equal to the weight force of the average vehicle. Also, the hyperloop intended to remove air resistance by creating partial vacuum in a tube is more dangerous than the Titanic. Lastly, Tesla has been successfully tested in jet and rocket propulsion. It's a topic to be studied by all engineers in this field. 🚴三 happy traveling.
Tesla might be the most underappreciated engineer of all time. Alan Turing aka "The Father of the Computer" is another, albeit a computer scientist. Any video that celebrates visionaries is a plus in my book. Thanks Sabin!
I have never seen an actual *working* pulsejet engine using the Tesla valve. The reason for this is that the valve is too "soft" and absorbs a lot of gas before it is "full" and the choking effect becomes pronounced enough to cause compression in the combustion chamber. For that reason, any engine built with such a valve would be unlikely to run well -- if at all.
@@melonlord1414 I have built a *lot* of pulsejets. I was in an episode of Scrapheap Challenge and also technical advisor to Junkyard Megawars on their pulsjet drag-boat build.
Yes, like an alternating current, which revolusionized electricity in our world and more inventions through it. I admire this person, it's amazing what he did.
tesla was working under edison. edison told tesla that he will give him 1000$ if he can improve the running time of a lightbulb to 10mins. Tesla improved the running time to a time where the lifespan couldnt be tested in a few days. when he wanted to receive his 1000$ edison basically told him to fuck off. after this tesla left the company. so tesla only improved the lightbulb but from a few seconds to a time that made them usable even 100 years later. thats also why the lightbulb is patented by edison, because he owned the researchcompany
He pressurised the pressure to make a big pressure which gives pressure to the pressure which gives enough pressure to crush anything but P R E S S U R E
I'm guessing the main reason this type valve hasn't caught on is simply because, as stated, it can not complete block the reverse flow. For instance water without a lot of pressure behind it (from static height or a pump) will create less vortices and therefor less resistance. The harder you push the water through (use a big pump), the pressure loss will increase exponentially, and so in relative terms it will be more efficient. It still won't stop flow completely though. It will also mean more damage to the valve due to pit corrosion (the same you get on ships propellers), and that would severely restrict the lifespan. But it is certainly an ingenious design, no doubt.
That’s not necessarily a bad thing. When you have low flow and low pressure, the moving parts associated with a true one-way valve will be less likely to fail and will have less associated wear.
Tesla's "valve" is a piece of junk. its only directional orrifice that restricts one side more than the other. It has no practical use. If you needed a 1 way orrifice... check valves and a spillback loop would be cheaper than manufacturing this POS
I love it! Tesla basically created a Diode which is an electrical component on circuit boards which will only let current flow in one direction - except he created the "Fluid" version of a diode. Which is awesome. I just watched the tesla turbine video and it seems he was doing what we do today just with fluid instead of pure electricity.
Personally, I wouldn’t say his ideas were simple as what he provided to the world with Alternating Current is still quite complex to the average individual. When you dive deep into his research and inventions, it’s downright remarkable. For the average individual, it’s just turn a light switch on or turn the tv on and it works.....but in reality with frequencies, potential differences, step up or step down transformers, AC motor and generators and the Battle of Currents, he changed the livelihood of the entire world and died penniless and infamous.
This is pretty amazing video on Tesla, very innovating, educating and inspiring, young lads should go into more of things to build a greater and invested future for themselves
This crypto of a thing I've got interest in investing but afraid of doing it on my own to avoid loss from my own end 😕🥴, and also would love how to trade it too
You guys forgot to mention another genius effect of this valve, which is the reason why it isn't near 180° (for example 178°): when the flow of one secondary stream mixes with the main stream, it doesnt just slow the mainstream down, it redirects its forces into the following secondary stream, since the secondary flow comes in at an angle instead of (near-)directly from the opposite side. Thus the force in the following secondary valve is increased, helping it to slow down the main stream even more.
@@timprescott4634 No, he pointed out that the critique is ridiculous, because completely stopping the flow is not what this invention is about. Knowing the most efficient way to reduce flow rate is in many cases exactly what's needed. Also with enough loops you can get a almost coplete seal. Not having 100% efficiency does not reduce the usefullness of this invention.
@@palodoxaliqua5809 No, he didn’t. Had he done that I wouldn’t have said anything. He just punted to the intellectually bankrupt, “What have YOU done” reply which is RIDICULOUS.
i was a plumber for years. this valve is a joke. it cannot do what's advertised. want proof? go ahead and try to find a video of this valve in operation. the water shoots out either side just as fast as you pump it in the opposite.
@@__shifty You know when this valve could work? Lets say you have a junction with one side a normal pipe, and the other with this valve, the water will obviously choose the way with the less resistance. If you somehow had a pipe blockage or an overflow in the other pipe, the water will then be forced to move into the valve. This is a scenario i think it would do a good job at. It is not a valve that can stop water when you force into it. It can only be a resistive valve.
Yes, showing actual fluidic components and models would be helpful for understanding. Notice the pulsing, as this is not only a partial diode but a partial fluidic oscillator.
May be they don't have a wood or metal worker? Animations worked well enough as even if you could see though a plexiglass face, due to the valve slowing the flow, you could not see the direction of the water flow. This would then need animations of arrows again. What I would find interesting is more mathematical information. How long, at what diameter, fin size, and liquid pressure going into.
That would substantially increase production costs. You might be able to get someone like William Osman to do a video fabricating and testing a Tesla valve.
@@davilathegreat not really. A cnc can cut out one for very cheap, and would have elevated the video above ufo sightings videos. You know, animations are costy as well.
@@Tiriris They are obviously working from an animation studio. It might be cheap for youtubers who perform on-screen, but that requires a whole new set of equipment and staff.
@@Drottninggatan2017 I think not exactly... the Tesla's Regulator works the same way as an one-way valve, but instead of completely blocking the current, it supresses its flow. In the example of the video, the mecanism just had to be turned around because there was only one current to flow through it.
@@Drottninggatan2017 Just like any other one way valve, the purpose is to restrict fluid to only travelling in one direction, and not the other. Your comment is meaningless.
So this valve can only reduce pressure and not completely stop the flow of liquid. So complete stopping of water without moving parts still is impossible
When you look at his achievements inventions and abilities, stacked against any other man throughout the entirety of humanity, that we know of, Nikolai Tesla is by far the number one greatest mine.
Let’s not forget about Newton. That man defined our current understanding of classic mechanics and created amazing mathematical tools that help the ordinary man to reach the extraordinary (calculus)
One thing that would be worth mentioning is that Tesla's design relies a lot on Bernoulli's principle. The trade off, in this application, is between pressure and speed. The speed is determined by the Coandă effect. According to the definition, if a fluid meets a curved surface, in our case the added obstructions, it will attempt to follow it. When this happens, the fluid that needs to travel further on the encountered obstruction will speed up (and drop in pressure), resulting in a higher velocity, which will result in the diverging stream clashing with the main stream, obstructing it
Yes, and the design also has similar affects as Archimedes describes with pulleys. But most importantly it all ties into the theroy of relativity and how we are moving thru spac and time. I think
@@mirceastaicu4131 There is no "correct theory", it is simply a theory, not having all the datum of each subsequent obstruction and / or separation of the fluids. Basics in physic... the more obstructions in the flow path, the lower the ve locity of the flow and the increase in the pressure, if there is a constant force applied to cause the flow i nt the fiorst place
So the answer to can you create a valve without a moving part question is NO. The Tesla valve increases the pressure drop in one direction so the flow will be reduce drastically but their will be a flow... It allows then a control of the flow rate not a perfect stop of it. You would not be able to use this valve instead of all the valve that you shown at the beginning of the video.
But at the start of the video (which is seen by way more people then the end (that is true for ANY video)), he heavily implied at least, that it was possible to make a actual one-way non-moving parts valve on par with the ones he showed with moving parts
@Palo Kan Yes, because in such a place a total valve is not needed a flow decrease is enough. If the answer to the proposed question had actually been "yes" the only places the other valves would have stayed would be if there wouldn't have been enough room for the tesla valve, but as it turns out it only replaced the valves in a few places where a flow decrease is enough, the vast majority of tradition moving parts valves were not replaces because they need to shut the water completely
@@GummieI I echo what you said, AND: “Replaced ___ valves in modern jet engines” implies the more traditional valves with moving parts were used in those sections of jet engine first. Show me. Were they? I have zero background in jet engine history or design. But I want to say NO, those traditional valves with moving parts were never used successfully in those sections of jet engine. So the “Tesla valve” replaced nothing in modern jet engine. “Found application in” and “Replaced” are two very different things.
One additional perspective: Tesla thought in oscillations and capacity - As demonstrated in his work on alternating current. While this valve works for steady-stream applications (like constant pressure water flow), it is intended for oscillating flow (like in the pulsejet engine).
Tesla was intrigued by the idea that vibrations, so basically sound, had the capacity to mimic other chemical and physical reactions. Modern science now calls this study phonons. Later, he would update his ideas to include sonic resonances from many different phenomenon. This obviously influenced his work on radio and alternating current. And directed his ideas later in life about wireless electricity, through microwave transmission. He probably didn't have an understanding of microwaves yet, but that is what he was thinking about.
I’m sure had Tesla directed more time and contemplation towards this valve , he would have incorporated a full stop application. But to serve as an indication of the type of mind Tesla possessed, he was at least as brilliant as Edison, if not more, and fit to sit at the table with Einstein
Tesla was known to think of physics in terms of waves, and I mean all fields of physics he dabbled in sincerity. It's a neat paradigm of mind, the wave-form. Even in software engineering, with many interacting parts, it can be useful to think of it in terms of waves when you debug and troubleshoot.
@@byronndavis1074 I would redirect the fluid all back to the original source mono directionally, this would be equal pressure in opposite direction of original flow, they would cancel each other out
That’s what I was thinking. For a sump pump check valve. Only problem is those are supposed to be vertically integrated. But I would imagine that the sound of it turning off would be drastically reduced if you put a couple 90 degree elbows just above the pump. It would of course need a traditional shut off valve below it though. I mean even the more expensive “quiet” is by no means quiet. And they break, too.
That is EXACTLY what I came away with. It would slow the water by a great deal..but it couldn't stop it. Not without a shutoff VALVE to do so. I guess I am to stupid to understand what they mean by the word..VALVE. 😂😂😂😂✌️
No, not a pressure regulator but a flow regulator. Like in drip irrigation. I do wonder how the flow reacts to an increase in a higher or lower pressure.
@@igoranisimov6549 wdym "never used"? at 5:43 he says "model valveless pulse jet engines use the tesla valve to replace the reed valve in conventional pulse jet engines"
@@igoranisimov6549 bruh he says model valveless pulse jet engines USE the TESLA VALVE to REPLACE conventional pulse jet engines that means they replace the reed valve for the tesla valve.
@@harrisonwells4600 nah nigga, he was part of the system n they where like "wtf you trying to do kill us all? We biding time here tell the next cyclic disaster." I'm white btw... I got my black card lol.
I would call it more an anti-return valve than a classic valve, mostly because if you want to stop the directed flow...u have to move something anyway. Besides that - very interesting piece of material :)
It's not meant to be a shut off valve, just a one way valve to prevent contaminates from entering the source. We call them check valves. We use them in almost every building and system that uses water. Here Tesla created the same effect in a more efficient way, without moving parts, by creating pressure differentials. In the little clip where water is flowing into the black pan, contaminates would not be able to enter supply tank because of the resistance offered by the device in combination with the positive pressure from the supply. It works as well with airflow which is why it is seen here being used in the jet propulsion application. The positive pressure from the engine and the increased resistance at the prevent backflow of fresh air. I hope this clears up the type of valve and some basic applications for it and, most importantly, why.
@@JSpradley123 I think you underestimate available valves. We have 100'es of valves at the factory and they all seal fluids 100% at pressures under 5 bar. (different story for gases or fluids under high pressure) The only real maintenance is replacing the rubber seals once every couple of years (depending on the usage)
It's not designed to be a constant pressure valve. Under pulsing conditions, and with the right size/length conduits for the density of the fluid and pulse width, it effectively does block flow completely. Think reed valve, not water faucet.
The counter-intuitive aspect is decreasing pressure during convergent flow. While velocity increases, one perceives that squeezing a flow into a smaller volume will increase pressure rather than decrease.
Can you explain in other words/examples why this happens? My mind has trouble dealing with this, and I had always thought the exact opposite. While not exactly important in my line of work, it sure can be embarrassing if I get this wrong on such a fundamental level, and I'll be teaching an apprentice soon, so help on this would be greatly appreciated.
Makes you wonder if they had Tesla's works in mind when designing tire treads that push rain out from under the contact patch. Cuz I'm looking at the first set uof examples up to the 3 minute mark and can't help but see tire technology as well.
this is so interesting. watching the flow of water has always intrigued me. whether being the oceans waves, my shower drain, rivers and streams, or how it looks with vibrations.
Just thinking outside the box, he is thinking about biology to make mechanics and fluids work. This structure looks exactly like a shoot system of a plant.
Yeah I noticed it too... These old school geniuses observed nature very precisely and they use to find solution to many problems in nature... Finally people in present era are starting to do the same & so Biomimcry is increasing now...
@@BGraves No offense but that's an oversimplification: "Granted, my understanding of physics and engineering is largely autodidactic and therefore incomplete, so this may be incorrect. Many of the arguments against this valve seem to be centered on the fact that it cannot 100% stop flow when fluid/gas is introduced from the restricted side (RS) while the unrestricted side (US) has no flow into it. For them, this means that the valve does not work. However, it seems to me that that is not the correct usage for a valve such as this. Rather, it is an effective way to show how flow within the valve works. Under working conditions, I believe the valve would work to prevent a complete flow reversal in a single-direction flow environment. Because of the design, reversed flow entering from the RS loses pressure as it moves through the valve, which allows the intended flow from the US to overpower the reversed flow and keep the larger system working correctly. In application, this would be useful for situations where backfire can occur, as it would largely prevent exhaust gasses from flowing backwards and reaching the combustion chamber prior to the valve. The lack of moving parts to prevent backfire means fewer places for mechanical failure and fewer necessary redundancies to prevent catastrophic failure. One-way valves also introduce a certain amount of drag/impedance into the system during normal operation and the Tesla valve appears to have a far lower amount of drag/impedance during normal operation, which may be another reason why it is being used in experiments in lieu of mechanical one-way valve." - fogotn 1 above this comment
Whilst being up...Googling.."Do penguins have knees.." I ended up here by a mistake (knocking my forehead into the keyboard I guess...Falling asleep!), hence being unable to answer that question, I'm totally unable to google it again... BUT, I now know how Tesla used pressure to kill pressure...Thanks!!
Simple and effective. Almost all of his design's follow this principle. He thought on multiple levels including engineering and construction cost. From top to bottom even his most complex creations, were simplistic in the eyes of other engineers of the time. Tesla was a genious amongst genious's.
Under steady state conditions this valve will only yield a constant pressure drop without any further control to the pressure or flow. It looks intriguing but it is just one design for breaking a fluid during its flow pattern. Valves like these are actually horizontal orifices much like vertical orifice used in pitot tubes to measure pressure differentials. The real benefit to control would be if the directing vane angles could be altered through another mechanism to then alter the flow and pressure gradient through each subsequent units.
once we introduce moving parts, the basic spirit of the invention may get effected. i am wondering about additional units arranged in a pattern, some how creating a fluid transistor/ diode kind of circuits.
It's really not that incredible. I can't understand how a person couldn't come up with this if you were specifically looking for a one way valve with no moving parts. The first image that enters the mind is surfaces or mechanisms which grip or engage in one direction. Like a ratchet or running shoes. Then your brain combines those forms with a pipe. Then it see this would not work as is or at best provide very minimal extra resistance in one direction. Then your brain says, how can we increase the resistance? And it answers itself and says by creating a secondary flowpaths which apposes the primary.
What really bothers me is that if somebody did something similar today, you wouldn't care. You care because Nikola Tesla did it. Because of his other inventions. You also care because somebody slapped the letters Tesla on a billion dollar company and now anything related is amazing. The guy asked himself how to restrict water flow. All you need is a material for water to run through and move things around until you are satisfied. Then, you show it to the public with little success because the market did not need the solution or your sales pitch was weak. Then, you die and wait until somebody makes a company with your name on it and an organisation decides to use a handful of valves using your design. That is how you make a Tesla valve. No advanced formulas, no string theories, just carve out some wood and drive some water through it. Alternatively, replace the wood with clay.
Its different, In veins its more like a one directional feathered structure. More like the one which was shown in this video at the beginning . One side flow of blood becomes easy when pumping while the design restricts the backward flow of blood
actually he was NOT. There are designs and mechanics that far exceed anything he produced various compelling theologies, and physics. like the canaanites that learned to move 2000 TONNE solid rocks stones from quarries. Other created intricate precisely tunes musical instruments 4-6 thou[sand years ago, great furnaces with grape juice & copper vats making HEAT TO furnace and produce metal swords. ETC.
@@ashqelon7267 I think one big flaw in that logic is that the inventions you reference were likely the life's work (or multiple life's work) of whoever invented them. Whereas Tesla created this as well as hundreds of other history changing inventions/concepts (mostly in electronics). I get it, people seem to worship Tesla. But, just because he might be over-hyped doesn't mean he wasn't a formidable genious.
I was just looking for fishing spots near me on google earth. When I realized the river buy me has a whole bunch of branching nodes like a tesla valve, so I can here for a refresher course. Thanks for the video. I wonder if he got the idea from witnessing this phenomenon in other rivers near him.
I didn't realise this, I thought that recirculation was best avoided in the cardiovascular system and that the venus system has moving valves. also the elastic properties of the arterial wall help propel blood through the system. Venus flow is dependent partly upon muscular compression of the venous system and valves. Recirculation is massively avoided in the arterial and venous system such as the Miller Cuff using during femoral artery bypass (if I recall correctly) and in arterial aneurysms, recirculation and stagnation cause sclerotic build-up and eventually stresses that cause rupture.
@@JohnnyKronaz I always felt that school was about 'doing what I was told'. "I have set you this task, now do it." I *learned* more and interesting things by reading at home. I would then bring my learned knowledge into school and share it with classmates and teachers, who all thought I was really intelligent. I *wasn't* but I just knew stuff because I was learning when I wasn't in school. I ended up with a reputation as a brainy kid, while my teachers thought I was both brainy and distressingly lazy or unfocused (because I just wouldn't do the work set in class or as homework). I *was* unfocused and poorly motivated in school, because I wanted to learn things and the school didn't teach me the things I was interested in learning. So there was the killer dichotomy. I got really average grades in my finals, scraped through college and didn't do uni. I am considered extremely brainy and clever, although my CV looks like nothing much. The individual child's ability and the state education system are and were tragically divorced and doing nothing for many children's development prior to going into the working world. (Because, let's be fair, most employers still look at grades, not at the individual's grammar and syntax in the application).
TESLY was mad insane. But he also looked at the world differently then most people do i belive he had dyslexia. So did Eddison. Being able to look at somthing with a fresh perspective and ignore others belief in limits your open to try somthing not looked at before becuse once someone figured somthing out they stoped looking thinking it was the best and only way. But if you think about it the old saying is " more then one way to skin a cat" you just can't use the same old kitty. And you think thd mouse was scared.
My physics professor kept talking bad about Tesla he claimed he wouldn’t respect anyone who don’t understand Maxwell equations , I have great respect for Tesla .
Same here. Tesla has great inventions. All the scientist has. People are so into soiling tesla's reputation nowadays. We have all the technology in this age which any inventor would dream of having. 3D printers are amazing stuff. But the people this age are blessed with so many high tech stuff that we eventually dont make use of stuff we learn because of the convenience. We forget and be reliant. From time to time, watching simple design like this fascinates me. As a mechanical engineer. It's important have mind of this ideas that it conveyed to the engineers and those who willing to learn it. Instead of who that are taking credits for that.

It is kinda common for genius scientist to work in various areas, it's just usually they impact certain field of study so much, that it overshadows their achievements in other fields, which are remarkable by themselves
Electricity is kind of similar to fluid, except it's the electrons which are flowing instead of atoms.
@@snowblazed3442 i'm pretty sure you can't create a tesla valve equivalent with wires =v however i'm a software engineer so my knowledge in the matter might be limited
Fluid and electricity both take the path of least resistance.
@@dtom2126 hmm so every secondary flow could be wires from a higher resistance than the ones used for the primary flow ? =o Now it actually seems plausible
The interesting thing about this apparatus is that the reduced flow from the output side is fairly consistent no matter how much pressure is on the input side. It's not adjustable but this would have applications where someone would need a relatively stable volume of liquid flow regardless of the changing input pressure. I think that is the real purpose of this valve, not so much being a one way valve.
its a solid state oscillating pump, remember he was working on pumps
I wonder if there’s a lower threshold whereby if the input is slow enough, the various divergences and vortices are minimised, therefore the the output would be increased compared to if you had a higher input (which would seem to create more restrictive flow?)
@@oscarwoodly7392 i was wondering the same, anyone got answers?
There's probably a fairly linear relationship between input pressure and output volume.
I think you are right. It’s a simple and robust way to meter something using higher pressures elsewhere. It really can’t stop flow because it relies on the dynamics of flow to even work.

Superb Animation ! , i am big fan of Nikola Tesla😊🏆🏆🏆🏆🏆🏆🏆🏆🏆
When you say "let's see it work" pretty sure everyone was expecting a real life version. You can make anything happen with computer animation
Can you show the difference of water speed in a valve? It's an animation based on laws that are accepted. Like animating an object falling because we know gravity exists. Jesus
@@lick28 His point was that you can animate anything. You can animate the valve breaking from excess pressure. You can animate an anvil falling on it. You can animate glitter coming out of the other end. You can also animate generally accepted "laws" in the logic of children's cartoons but that does not make them real nor evidence of any kind of "laws". And yes, you can show the difference of water speed in a valve. Today we have plastics and glass to make small scale low pressure valves. We also 3D printers and pressure gauges. I am surprised that a reasonable person would suggest that the only way to demonstrate how a valve works would be through computer animations. Because we all know the significance of computer animations when Nikola Tesla made the valve in question...
@@guywiththebottle and my point is that there's no reason to make up anything false. It's also much easier to just animate something we know to be the effect of a certain action than to go out of our way to waste physical resources like water and money. It's also easier to articulate how the inner workings of something goes in an animation as you can highlight the important things to be noted. Complaining about the fact that it's animated in this context seems very nitpicky
@@lick28 There is reason to make up something false if you can get away with it or do not know better. People care about 'fake news' more than ever and everybody is the publisher on youtube. The guy asked for another reason to believe the premise of the video. If people know the effect of "a certain action", there wouldn't be a point to making the video. Is it a waste of physical resources to teach people about valves? You can highlight whatever you want in an animation, that was the point of the critique. Not sure why it would be nitpicky that the guy expresses that he would be more convinced by a recording of a stream of water rather than a simulation of a stream of water.

@@laernulienlaernulienlaernu8953 That's a stupid comment. Tesla is a cult in the US and much of what's attributed to him is mythical. Whether or not I'm smarter than he was is irrelevant. The fact is that Tesla was a talented engineer but was not a physicist of any great ability. His achievements are greatly overstated and the hyperbole in this video is both incorrect and pathetic.
As a 20 year master plumber I love the design due to it not having any mechanical parts that could fail for a pressure reducing valve this would be great
Also the primary flow in tesla valve isn’t a straight line. For every section of the “bucket” structure the primary path is tilted so that it matches the entrance of the next bucket structure, so making is very effective at dividing the primary flow into a secondary flow that opposes itself
Something not mentioned in this video is that alongside the mentioned flow restrictions of the Tesla valve, after the first switchback the "main" flow will be directed towards the next switchback each time. It doesn't appear to be an even split into primary and secondary.
The teaching method is excellent. Tesla valve is remarkable.
One of the very best demonstrations I've ever seen on RUclips, and short and sweet just enough for my attention span.

Agreed. I was surprised by the 4k+ dislikes. Perhaps it was from people unable to understand the video... or maybe they are just Edison fanboys 😜
Claiming to be a “total physics” video without demonstrating a real world model of such a simple device is a fail. The simulation software is fine but not a complete picture.
Also this valve is crap under any appreciable pressure. You’d get backflow in no time. It demonstrates that it is not possible to make a true check valve without moving parts. A small ball check valve easily handles the job.
@@sircrapalot9954 Application of newer technology is much needed. A train 🚂🚋🚃🚋🚃🚋🚃in a tunnel with walls that reflect the divergent air on to the rear of the train would have twice the efficiency of trains today. Using turbo jets to clear air from the front would prevent wind resistance in the tunnel while additional forward thrust is developed. Directing this displaced jet of air on to a modified Tesla mechanism on the tunnel walls to redirect the air jet on to the rear of the train would again add forward thrust. This is significant since wind resistance at 100 mph is equal to the weight force of the average vehicle. Also, the hyperloop intended to remove air resistance by creating partial vacuum in a tube is more dangerous than the Titanic.
Lastly, Tesla has been successfully tested in jet and rocket propulsion. It's a topic to be studied by all engineers in this field. 🚴三 happy traveling.

I have never seen an actual *working* pulsejet engine using the Tesla valve. The reason for this is that the valve is too "soft" and absorbs a lot of gas before it is "full" and the choking effect becomes pronounced enough to cause compression in the combustion chamber. For that reason, any engine built with such a valve would be unlikely to run well -- if at all.

Whudda man whudda man whudda man whadda mighty gooood mannn
I'm guessing the main reason this type valve hasn't caught on is simply because, as stated, it can not complete block the reverse flow.
For instance water without a lot of pressure behind it (from static height or a pump) will create less vortices and therefor less resistance.
The harder you push the water through (use a big pump), the pressure loss will increase exponentially, and so in relative terms it will be more efficient. It still won't stop flow completely though. It will also mean more damage to the valve due to pit corrosion (the same you get on ships propellers), and that would severely restrict the lifespan.
But it is certainly an ingenious design, no doubt.
That’s not necessarily a bad thing. When you have low flow and low pressure, the moving parts associated with a true one-way valve will be less likely to fail and will have less associated wear.
You can put a mechanical vale at the end which will be suspectible to less wear and tear.
Still useful 5:30
Tesla's "valve" is a piece of junk. its only directional orrifice that restricts one side more than the other.
It has no practical use. If you needed a 1 way orrifice... check valves and a spillback loop would be cheaper than manufacturing this POS

You guys forgot to mention another genius effect of this valve, which is the reason why it isn't near 180° (for example 178°): when the flow of one secondary stream mixes with the main stream, it doesnt just slow the mainstream down, it redirects its forces into the following secondary stream, since the secondary flow comes in at an angle instead of (near-)directly from the opposite side. Thus the force in the following secondary valve is increased, helping it to slow down the main stream even more.
I was waiting the entire video for them to mention that 😁

want proof? go ahead and try to find a video of this valve in operation.
the water shoots out either side just as fast as you pump it in the opposite.
@@__shifty You know when this valve could work? Lets say you have a junction with one side a normal pipe, and the other with this valve, the water will obviously choose the way with the less resistance. If you somehow had a pipe blockage or an overflow in the other pipe, the water will then be forced to move into the valve. This is a scenario i think it would do a good job at. It is not a valve that can stop water when you force into it. It can only be a resistive valve.
You acted like the Tesla valve, much resistance but in the end you've watched it.
😂😂😂
Well I'm suprised the video does not show an actual water test.
Yes, showing actual fluidic components and models would be helpful for understanding. Notice the pulsing, as this is not only a partial diode but a partial fluidic oscillator.
May be they don't have a wood or metal worker? Animations worked well enough as even if you could see though a plexiglass face, due to the valve slowing the flow, you could not see the direction of the water flow. This would then need animations of arrows again.
What I would find interesting is more mathematical information. How long, at what diameter, fin size, and liquid pressure going into.
That would substantially increase production costs. You might be able to get someone like William Osman to do a video fabricating and testing a Tesla valve.

So basically a diode?
@@Drottninggatan2017 Just like any other one way valve, the purpose is to restrict fluid to only travelling in one direction, and not the other. Your comment is meaningless.

One thing that would be worth mentioning is that Tesla's design relies a lot on Bernoulli's principle. The trade off, in this application, is between pressure and speed. The speed is determined by the Coandă effect. According to the definition, if a fluid meets a curved surface, in our case the added obstructions, it will attempt to follow it. When this happens, the fluid that needs to travel further on the encountered obstruction will speed up (and drop in pressure), resulting in a higher velocity, which will result in the diverging stream clashing with the main stream, obstructing it
Precisely! ....( I had no idea )

@@feizal7554 Can you share with us a link to a resource that outlines the correct theory? I'm sure a lot of people will be curious about it

@@mirceastaicu4131 There is no "correct theory", it is simply a theory, not having all the datum of each subsequent obstruction and / or separation of the fluids.

Water: flowing peacefully..
Tesla: No..we don't do that here..
So the answer to can you create a valve without a moving part question is NO.
The Tesla valve increases the pressure drop in one direction so the flow will be reduce drastically but their will be a flow... It allows then a control of the flow rate not a perfect stop of it. You would not be able to use this valve instead of all the valve that you shown at the beginning of the video.
That's what he said at the end of the video, that there will still be flow so technically its not a non-return valve.
But at the start of the video (which is seen by way more people then the end (that is true for ANY video)), he heavily implied at least, that it was possible to make a actual one-way non-moving parts valve on par with the ones he showed with moving parts
it still replaced the former valves in modern jet engines.
@Palo Kan Yes, because in such a place a total valve is not needed a flow decrease is enough. If the answer to the proposed question had actually been "yes" the only places the other valves would have stayed would be if there wouldn't have been enough room for the tesla valve, but as it turns out it only replaced the valves in a few places where a flow decrease is enough, the vast majority of tradition moving parts valves were not replaces because they need to shut the water completely
@@GummieI
I echo what you said, AND:
“Replaced ___ valves in modern jet engines” implies the more traditional valves with moving parts were used in those sections of jet engine first.
Show me. Were they?
I have zero background in jet engine history or design. But I want to say NO, those traditional valves with moving parts were never used successfully in those sections of jet engine. So the “Tesla valve” replaced nothing in modern jet engine.
“Found application in” and “Replaced” are two very different things.
One additional perspective: Tesla thought in oscillations and capacity - As demonstrated in his work on alternating current. While this valve works for steady-stream applications (like constant pressure water flow), it is intended for oscillating flow (like in the pulsejet engine).
what i am doing here 2am reading comments, guess anything from NTesla is interesting :)
Aye, constant flow isn't impeded by the valve nearly as well as pulses.
It's very clear this was made to catch bursts of pressure 👌🏻
@@wastedwizard5112
I don't think so.
Tesla was intrigued by the idea that vibrations, so basically sound, had the capacity to mimic other chemical and physical reactions. Modern science now calls this study phonons. Later, he would update his ideas to include sonic resonances from many different phenomenon. This obviously influenced his work on radio and alternating current. And directed his ideas later in life about wireless electricity, through microwave transmission. He probably didn't have an understanding of microwaves yet, but that is what he was thinking about.
I’m sure had Tesla directed more time and contemplation towards this valve , he would have incorporated a full stop application. But to serve as an indication of the type of mind Tesla possessed, he was at least as brilliant as Edison, if not more, and fit to sit at the table with Einstein
Tesla was known to think of physics in terms of waves, and I mean all fields of physics he dabbled in sincerity. It's a neat paradigm of mind, the wave-form. Even in software engineering, with many interacting parts, it can be useful to think of it in terms of waves when you debug and troubleshoot.
interesting, can you give some examples by chance of what you mean by that?
It would be more accurate to compare this to a pressure-reducing valve, rather than a check-valve / back flow preventer.
Yep.
Was thinking the same.
I would love to see you do it. Just think of what would be accomplished and designed by you.
@@byronndavis1074 I would redirect the fluid all back to the original source mono directionally, this would be equal pressure in opposite direction of original flow, they would cancel each other out
That’s what I was thinking. For a sump pump check valve. Only problem is those are supposed to be vertically integrated. But I would imagine that the sound of it turning off would be drastically reduced if you put a couple 90 degree elbows just above the pump. It would of course need a traditional shut off valve below it though.
I mean even the more expensive “quiet” is by no means quiet. And they break, too.
That’s more like a pressure regulator than a stop valve. Still very cleaver though! 💡🤓
That is EXACTLY what I came away with. It would slow the water by a great deal..but it couldn't stop it. Not without a shutoff VALVE to do so.

It's not meant to be a shut off valve, just a one way valve to prevent contaminates from entering the source. We call them check valves. We use them in almost every building and system that uses water. Here Tesla created the same effect in a more efficient way, without moving parts, by creating pressure differentials. In the little clip where water is flowing into the black pan, contaminates would not be able to enter supply tank because of the resistance offered by the device in combination with the positive pressure from the supply. It works as well with airflow which is why it is seen here being used in the jet propulsion application. The positive pressure from the engine and the increased resistance at the prevent backflow of fresh air. I hope this clears up the type of valve and some basic applications for it and, most importantly, why.

“The Tesla valve cannot block the flow completely”
@Ronin
yes, there are 100% in the real world with valves, they will stop the flow of water.
@Ronin In real world, your sink never closes? Lmao.
Stella smith almost all valves leak. Bubble tight valves exists but they are $$$$$
@@JSpradley123 I think you underestimate available valves.
We have 100'es of valves at the factory and they all seal fluids 100% at pressures under 5 bar.
(different story for gases or fluids under high pressure)
The only real maintenance is replacing the rubber seals once every couple of years (depending on the usage)
It's not designed to be a constant pressure valve. Under pulsing conditions, and with the right size/length conduits for the density of the fluid and pulse width, it effectively does block flow completely. Think reed valve, not water faucet.
Every once and a while youtube brings us all to an interesting video like this and we all learn something new
The counter-intuitive aspect is decreasing pressure during convergent flow. While velocity increases, one perceives that squeezing a flow into a smaller volume will increase pressure rather than decrease.
Can you explain in other words/examples why this happens? My mind has trouble dealing with this, and I had always thought the exact opposite. While not exactly important in my line of work, it sure can be embarrassing if I get this wrong on such a fundamental level, and I'll be teaching an apprentice soon, so help on this would be greatly appreciated.
Makes you wonder if they had Tesla's works in mind when designing tire treads that push rain out from under the contact patch. Cuz I'm looking at the first set uof examples up to the 3 minute mark and can't help but see tire technology as well.
I just had to sub. Never heard of this before. So much stuff Tesls invented that is being used without us even knowing it.
this is so interesting. watching the flow of water has always intrigued me. whether being the oceans waves, my shower drain, rivers and streams, or how it looks with vibrations.
Just thinking outside the box, he is thinking about biology to make mechanics and fluids work. This structure looks exactly like a shoot system of a plant.
Interesting. Well...he studied a lot a subjects.
Yeah I noticed it too...
These old school geniuses observed nature very precisely and they use to find solution to many problems in nature...
Finally people in present era are starting to do the same & so Biomimcry is increasing now...
Too bad it doesn't work at all
I also thought of biology
@@BGraves No offense but that's an oversimplification: "Granted, my understanding of physics and engineering is largely autodidactic and therefore incomplete, so this may be incorrect.
Many of the arguments against this valve seem to be centered on the fact that it cannot 100% stop flow when fluid/gas is introduced from the restricted side (RS) while the unrestricted side (US) has no flow into it. For them, this means that the valve does not work. However, it seems to me that that is not the correct usage for a valve such as this. Rather, it is an effective way to show how flow within the valve works.
Under working conditions, I believe the valve would work to prevent a complete flow reversal in a single-direction flow environment. Because of the design, reversed flow entering from the RS loses pressure as it moves through the valve, which allows the intended flow from the US to overpower the reversed flow and keep the larger system working correctly. In application, this would be useful for situations where backfire can occur, as it would largely prevent exhaust gasses from flowing backwards and reaching the combustion chamber prior to the valve. The lack of moving parts to prevent backfire means fewer places for mechanical failure and fewer necessary redundancies to prevent catastrophic failure. One-way valves also introduce a certain amount of drag/impedance into the system during normal operation and the Tesla valve appears to have a far lower amount of drag/impedance during normal operation, which may be another reason why it is being used in experiments in lieu of mechanical one-way valve." - fogotn 1 above this comment
Whilst being up...Googling.."Do penguins have knees.." I ended up here by a mistake (knocking my forehead into the keyboard I guess...Falling asleep!), hence being unable to answer that question, I'm totally unable to google it again... BUT, I now know how Tesla used pressure to kill pressure...Thanks!!
lmao
Not a bad place to end up!
You're the cool version of insane.
@Ramzan good, now I don't have search that myself
I feel smarter because of the 6 minutes you've shared with me. Thank you.
What this explanation needs is a real situation with colored liquids to see it in action.
yeah, 'cause it in different color; yeah..
i can't help but wonder what his development process looked like. pure genius
Simple and effective. Almost all of his design's follow this principle. He thought on multiple levels including engineering and construction cost. From top to bottom even his most complex creations, were simplistic in the eyes of other engineers of the time.
Tesla was a genious amongst genious's.
Never heard about this. I’m sure there’s a lot stuff he has done which no one knows about !!
Under steady state conditions this valve will only yield a constant pressure drop without any further control to the pressure or flow. It looks intriguing but it is just one design for breaking a fluid during its flow pattern. Valves like these are actually horizontal orifices much like vertical orifice used in pitot tubes to measure pressure differentials. The real benefit to control would be if the directing vane angles could be altered through another mechanism to then alter the flow and pressure gradient through each subsequent units.
once we introduce moving parts, the basic spirit of the invention may get effected. i am wondering about additional units arranged in a pattern, some how creating a fluid transistor/ diode kind of circuits.
Yes, I am very awed by the man's genius!
One thing i always like about learn engineering that they always explain so well with the unbelievable animation. Love you from india 🇮🇳
The creator is Indian bruh
Nobody really knows how Nicolai Tesla mind worked. He was a genius.
Absolutely agree!
Its Nikola not Nicolai
Cant believe how his mind was capable of thinking like this. What a genius!
It's really not that incredible.
I can't understand how a person couldn't come up with this if you were specifically looking for a one way valve with no moving parts.
The first image that enters the mind is surfaces or mechanisms which grip or engage in one direction. Like a ratchet or running shoes.
Then your brain combines those forms with a pipe. Then it see this would not work as is or at best provide very minimal extra resistance in one direction.
Then your brain says, how can we increase the resistance? And it answers itself and says by creating a secondary flowpaths which apposes the primary.
What really bothers me is that if somebody did something similar today, you wouldn't care. You care because Nikola Tesla did it. Because of his other inventions. You also care because somebody slapped the letters Tesla on a billion dollar company and now anything related is amazing. The guy asked himself how to restrict water flow. All you need is a material for water to run through and move things around until you are satisfied. Then, you show it to the public with little success because the market did not need the solution or your sales pitch was weak. Then, you die and wait until somebody makes a company with your name on it and an organisation decides to use a handful of valves using your design. That is how you make a Tesla valve. No advanced formulas, no string theories, just carve out some wood and drive some water through it. Alternatively, replace the wood with clay.
@@guywiththebottle but I mean he was a genius and alsoal a successful. person. But I get you think he has become another hip geek fad
Video is more than wonderful Keep it up I want more innovative hydraulic ideas
He is a genius wow. Im impressed.
This technique is already in our veins
Yes
Elaborate please
Its different, In veins its more like a one directional feathered structure. More like the one which was shown in this video at the beginning . One side flow of blood becomes easy when pumping while the design restricts the backward flow of blood
One of the greatest minds to ever walked this earth.
Just imagine what could he accomplish if he was living in our times
actually he was NOT. There are designs and mechanics that far exceed anything he produced various compelling theologies, and physics. like the canaanites that learned to move 2000 TONNE solid rocks stones from quarries. Other created intricate precisely tunes musical instruments 4-6 thou[sand years ago, great furnaces with grape juice & copper vats making HEAT TO furnace and produce metal swords.
ETC.
@@ashqelon7267 wtf are you talking about ? Where are your sources on this ?
@@ashqelon7267 I think one big flaw in that logic is that the inventions you reference were likely the life's work (or multiple life's work) of whoever invented them. Whereas Tesla created this as well as hundreds of other history changing inventions/concepts (mostly in electronics).
I get it, people seem to worship Tesla. But, just because he might be over-hyped doesn't mean he wasn't a formidable genious.
I was just looking for fishing spots near me on google earth. When I realized the river buy me has a whole bunch of branching nodes like a tesla valve, so I can here for a refresher course. Thanks for the video. I wonder if he got the idea from witnessing this phenomenon in other rivers near him.
These principles also apply to the human cardiovascular system.
Incredible. I'm going to research that. I'm guessing that the tubes get increasingly smaller?
Exactly that's what I was thinking
I didn't realise this, I thought that recirculation was best avoided in the cardiovascular system and that the venus system has moving valves. also the elastic properties of the arterial wall help propel blood through the system. Venus flow is dependent partly upon muscular compression of the venous system and valves. Recirculation is massively avoided in the arterial and venous system such as the Miller Cuff using during femoral artery bypass (if I recall correctly) and in arterial aneurysms, recirculation and stagnation cause sclerotic build-up and eventually stresses that cause rupture.
Actually our heart have moving part. It's not rigid
I only noticed until you mentioned it 😳
Each of the little "islands" looks just like the cross-section of an airplane wing.
Interesting observation
You're on to something, I can tell...
billucf96 the Bernoulli principle at work
Interesting
yes, bernoulli's principle
Such a simple thing yet no1 thought of it. Thats the brilliance of Tesla.
Excellent video ! 👍
I don't know why I'm watching this, I don't even fluid engineer
Zheka K how much watch?
It never hurts to learn
well you can become one!! good luck!
Anything with Tesla's name on it aells
Procrastination
The greatest mind mankind ever had!
I believe Einstein even agrees with you!
The democrats would credit Nancy pelosi with that title
i think it will be hundreds (if not thousands) of years until a mind like that shows again
@@kregadeth5562 Well here comes that one guy haha
Why is a republican on this educational video? usually they are not that bright...
What a guy strange how we never learned anything about him in school.
Government school isn't about learning, it's about obedience. Show your work.
@@JohnnyKronaz agreed 100 percent my man.
@@JohnnyKronaz I always felt that school was about 'doing what I was told'. "I have set you this task, now do it." I *learned* more and interesting things by reading at home. I would then bring my learned knowledge into school and share it with classmates and teachers, who all thought I was really intelligent. I *wasn't* but I just knew stuff because I was learning when I wasn't in school.
I ended up with a reputation as a brainy kid, while my teachers thought I was both brainy and distressingly lazy or unfocused (because I just wouldn't do the work set in class or as homework).
I *was* unfocused and poorly motivated in school, because I wanted to learn things and the school didn't teach me the things I was interested in learning. So there was the killer dichotomy.
I got really average grades in my finals, scraped through college and didn't do uni.
I am considered extremely brainy and clever, although my CV looks like nothing much.
The individual child's ability and the state education system are and were tragically divorced and doing nothing for many children's development prior to going into the working world. (Because, let's be fair, most employers still look at grades, not at the individual's grammar and syntax in the application).
Bruh, I literally learned about this guy in school.
@@KrillLiberator holy hell, are you me?
wow, you took a simple concept and made it complex
Nicola Tesla had a broad field of interest, he was a generalist, such a great man!
I am amazed and surprised by Tesla at every turn. What a genius, Edison and Co. should be ashamed.
Edison was a greedy man,didn't anyone become better than him
TESLY was mad insane.
But he also looked at the world differently then most people do i belive he had dyslexia. So did Eddison.
Being able to look at somthing with a fresh perspective and ignore others belief in limits your open to try somthing not looked at before becuse once someone figured somthing out they stoped looking thinking it was the best and only way. But if you think about it the old saying is " more then one way to skin a cat" you just can't use the same old kitty. And you think thd mouse was scared.
@levi blankenship Current kills, it doesnt matter if its alternative or direct.
@levi blankenship lmao
@levi blankenship It already is in your house genius.
My physics professor kept talking bad about Tesla he claimed he wouldn’t respect anyone who don’t understand Maxwell equations , I have great respect for Tesla .
The old saying remains true, you can educate your professor: Those who fail, teach.
Same here. Tesla has great inventions. All the scientist has. People are so into soiling tesla's reputation nowadays. We have all the technology in this age which any inventor would dream of having. 3D printers are amazing stuff. But the people this age are blessed with so many high tech stuff that we eventually dont make use of stuff we learn because of the convenience. We forget and be reliant.
From time to time, watching simple design like this fascinates me. As a mechanical engineer.
It's important have mind of this ideas that it conveyed to the engineers and those who willing to learn it. Instead of who that are taking credits for that.
