Finally! The external combustion engine has arrived!
good one
steam locomotives were external combustion ;)

There is something incredibly funny about your durdling little car at the end that manages to be sopping wet, made of cheap plastic, and on fire, all at the same time.
50 years ago, for a high school science project, I cobbled together a toy car with an electric motor connected to the wheels and driven as a generator, to demonstrate electric braking into a resistive load. With switch open, my toy car went fast down a ramp. With switch closed, the car went slow down the ramp. I give Tom an A++ for an excellent project!
Cool
I have an extreme urge on what to reply here but that would just be (probably) like begging
That makes sense. If you short circuit the two wires of a DC motor the rotor becomes harder to spin, you can even use it to test if two parts of a circuit are isolated from one another or not
The locomotives you see pulling trains use this to slow down without using the air brakes. There Is a large electrical resistance grid on the roof for what the railroad industry calls "dynamic braking".
You re both tom and the jury?
As someone who works with 44awg wire all the time, a trick we use to make soldering them easier is to just tie a knot where you want the solder to go, flame it to burn away the enamel, solder. Works well enough and saves a lot of headache.
ohh
putting a knot in that thing sounds harder than just soldering it, but ill keep that in mind
Flame it with just a lighter or something more aggressive like a blowtorch?
@@willpreston7797A match flame will easily burn away the insulation. It doesn't need to be high temperature.
@@willpreston7797 Even with just a lighter you need to be careful to not instantly melt away the copper :D
100% guarantee the discussion on work applied via the push or through the ramp will be a regular question on physics exams now. You even had me scratching my head until you broke out the force arrows, awesome demo!

@@lookawilduser I was trying to reference Nick's video "Taming the Tail-Sitter: Hover to Forward Flight Explained". This video is one of my favorite youtube videos, and I've watched it at least 15 times.

How it evolved from nothing into absolute silly invention just because is so amazing. Love it
This is just a more complicated version of the old "friction drive" toy cars which used a mechanical flywheel to store some of the energy imparted by the initial push to keep the toy car running for some time after you let it go.
I instantly hear their sound now

As a retired Engineer, I've always really liked your videos. This one is very interesting. Thank you.
Iam going to be an engineer soon and I like the videos as well 👆
Cool! Enjoyed it too
Will you be an engineer soon, or a retired engineer? Big difference haha 🌈 @@bauerm12
Almost jaw-dropping.
Glad to see the peltier car final go! I never realized how far away I was!
I love this video! I am a mechanical engineering student right now, and this video takes some concepts I have learned in dynamics, circuits, and thermo and combines them into two fun projects!
Bro that was awesome. Such simple concepts, so well explained and visual.. I am astonished. Awesome job!
That blue trike looks really steampunk, I want a hand cranked version to ride around on
I really like the design
A hand cranked motortricycle? Surely legs would work be- Oh. That's just a trike.
It looks like a Big Wheel or a Green Machine like kids had in the 70s and 80s.
every toy car maker should be taking notes - the right implication of this could make self propelled toy cars exponentially more fun
What notes, this technology is in practice since 1960s. It is used in toy cars for children, when they pull it back, the capacitor pushes the car forwards more than the actual pull.
@@KaavjeSahe-- Are those electrical capacitors, or mechanical springs with bi-directional gearing?
@@KaavjeSahe I didn't know those wind-up cars used capacitors. I figured it was mechanical.
@@CosmicFlux Some use Flaps, while some use capitcitors. Expensive ones use capacitors and the cheap ones use flaps. As a single capitor cost 13 Euros, cheap toy cars usually have a flap to move them forward.
@@KaavjeSahe a single capacitor cost like 42 cents, actually it's probably much lower if you buy from the right place (as a factory would)
I’m sure the shot at 5:33 was a labor of love to get right, the motion track/stabilization resolve is pretty great and it almost looked like you had a camera dolly/on tracks. the graphics pointing to things and being able to see how the pieces moved in concert was so nice. great job!
Awesome video as usual! Thank you for taking the time to film, produce and share it with us!
That generator trike is strikingly beautiful AND incredibly fascinating... Bravo mate!
You should keep the capacitor in the peltier module powered car. The motor draws power in short bursts when a magnet passes the reed switch. And so when the motor is not drawing current the thermoelectric generator is still converting heat into electric current and charging the capacitor. Otherwise, when the reed switch is open, the thermoelectric generator is unable to convert the energy because the current has nowhere to flow.
I was thinking that too. I don't know if there's any capacitance in the Peltier pad but if there isn't, I would think a capacitor would help.
@@SqueakyNeb There definitely will be some parasitic capacitance in the TEC but it will be very small compared to the electrolytic capacitor.
I have little experience with electronics/electrics and no experience with Peltier stuff, so I'm probably talking out of my ass here and feel free to correct me if I am, but I think this might not matter too much? The pad generates voltage via temperature differential between the sides, but if you're not drawing any current, surely it doesn't transfer the heat as easily as when current is being drawn, right? If so, when the switch is closed the pad generates a higher voltage due to the higher temperature difference, and you get practically the same effect because the temperature differential is acting as a capacitor anyway, isn't it? The way I'm thinking about it is best described as an electric version of a Stirling engine where you intermittently stop the flywheel (between coil pulses) which lets the heat build up which then makes it spin faster. At higher speeds where the air rushing by and cooling the pad is more of an issue I can see the sense in adding a capacitor, but again, assuming the stuff I said is accurate, a capacitor would just be another component for energy loss in the system. If I am wrong please do correct me, I'd love to learn more about this stuff.
@@PromptedHawk Ahh I really want to know the answer to this now. I think theoretically you're all correct. However, my suspicion is that the heat capacitance of the TEC won't be able to respond very quickly compared with the frequency of the motor. Therefore an electrical capacitor will be more efficient at harnessing the energy between pulses and would provide a measurable improvement.
would it be useful to place another peltier plate upside down on the first one, and power it when the reed switch is open, in order to keep the ice a bit cooler for longer?
This was an amazing well structured video. Thanks a lot Tom, I just subscribed.
6:33 "travels a fair way along the distance that I moved it" "now obviously not the whole distance because it's not 100% efficient" Putting distance in a car, I love it!
That might be the silliest thing you have made on your channel, which says a lot. Awesome video.
This is a really elegant and unique way to demonstrate conservation of energy, work, and power. Thanks for sharing.
Funny seeing you here!
Hey man, loved the easy explanations about the push test.
Great video! It makes concepts clear by example that are sometimes hard to grasp or explain to people.
That was an excellent macro shot of the reed switch in operation! Seeing the tiny contacts closing/opening as a magnetic field passes is difficult to see without magnification.
I work in a manufacturing facility and our Reed switches are covered in plastic and sealed, so this is the first time I had seen how they actually work instead of just knowing it wasn't working, so replace it.... Now I'm confused as to how the heck they break. Maybe bent back and forth through enough cycles until it broke? Or stuck fused together for some reason? Wondering if I just smack one hard against my leg if it will start working again? Probably go through 2-5 a week across all machines
If you add a supercapacitor to the output of the peltier, it might be able to run the motor with a lower temp differential. The motor uses current in pulses, so during the off times the capacitor would charge to allow for higher peak current when the coils are engaged
Exactly what I saw with the Peltier device experiment.... While the motor draws current, the Peltier device will have only so much energy stored within itself in between the motor pulses... A capacitor definitely makes sense in this application.... Two Peltier devices in series should provide a higher voltage which sent to a capacitor and fed to the motor via a Stepdown DC to DC converter to control the motor speed, should be able to achieve longer run times....
@@PeterMilanovski A linear regulator would be too inefficient, I think. Maybe a custom switch-mode power supply, with the frequency tuned to the frequency of the motor pulses at your desired speed. At that point you could probably even remove the reed switch, because what you've made is essentially a BLDC motor.
@@tissuepaper9962 exactly.... Linear regulators are good at what they do but the goal here is efficiency so a switching low dropout regulator is what's needed... I idea is you to remove as much load from the generator so by going with a high voltage low current generator, you are removing some of the load from it and then use a DC to DC Stepdown converter to do the heavy lifting to provide the low voltage high current that the drive motor needs...
All of these contraptions you made are simply delightful.
glad youtube recommended you to my homepage! super nice video!
That fire&ice trike was really too funny XD
All it needed was some leather and chrome, LOL
Your hand pushing the cars in those side-on comparison shots is very Monty Python! Fun project for sure, and a great counter-intuitive result in the push test.
What's counter- intuitive depends on how good you are at "intuiting". Einstein "intuited" relativity before there were any means of testing it. He was even able to intuit when & how it would be confirmed. A sufficiently intuitive experimenter could have noticed it was harder to accelerate the generator car up to the same speed as the freewheelng one on the flat because it takes energy to speed it up and to spin its generator, especially when it is charging a battery. That way it has stored not only the same kinetic energy as the other car, but has stored the extra energy it took to spin the generator, allowing it to travel farther. Intuition is facile use of knowledge to accurately predict outcomes of the interactions of laws and principles. The results are counter-intuitive only until you come to the proper explanation you could have anticipated with principles you already knew or until you have been taught a principle or principles you hadn't learned yet. Strive to test your intuition and objectively grade its success. That will strengthen it.
@@dennisbecraft1303 Pushing a car to 2 km/hr vs pushing a shopping cart to 2 km/r sure does take a whole lot more energy.
@@toolbaggers Especially if it's a Tesla with regen braking engaged.
Tom this is one of your coolest videos yet. So well explained
I get the impression you enjoyed making this video a lot. Thanks for sharing!
I've always been fascinated by this concept, not perpetual motion, but very efficient use of energy, so *almost perpetual*. Very cool to see it in action.
Check out lasersaber's videos. He has motors that run on milliwatts of energy. Powered by tritium lights, ionic atmospheric energy, ambient temperature change...
The electric trike Tony from Agingwheels made a video on might be up your valley then. It is just insanely efficient. Just don't confuse it for the one with pedals he also made a video on...
@@markellii3093 Robert not Tony.
It's not very efficient, it's just using very little energy.
This actually had so much good information in it to help get a grasp on the basics of generating electricity, and the losses that occur when doing so. It was under 15 minutes too! Much love from Scotland. Can't wait to see where you take this idea next.
Fantastic explanation! I understood that you should use a ramp for the experiment but couldn't quite figure out why until you explained that the energy require to push each car was different.
Loving this type of content bro, keep it coming!
That intro is fun because I truly think figuring out "ALMOST" perpetual energy devices is where everyone should be focused on & forget about "perpetual machines" completely. It's all about perspective. Especially now with all our advancements in tech. If creative enough it is possible for engineering to create very efficient devices. You could make a great kid's toy company with this creation. Could go onto shark tank lol and get it funded to make kids toy cars based off of this. It's pretty cool
randos when any youtuber makes anything: "turn it into a whole company bro"
it is already what everyone is doing in the energy industry
And needs copper. Less then ideal, especially if you can substitute it for more traditional design that can work with only few springs and everything else is plastic.
the reason the generator car can go further than the flywheel car in the ruler test is, that to push it you need more force which gives it more energy to begin with. and it can store more energy (in the flywheel, the magnetic field and the electric field in the capacitor)
Great video, Tom. Keep them coming. Keep asking the questions, and invention will follow.
Perfect video to help understand regenerative braking for the Australian GP this weekend.
What a great video! You've condensed three years of high school pyhysics in one gorgeous and elegant model, my sincere congratulations for your ingenuity!

@@ADBBuildtotally, but all electric sewing machines I've messed with were too nasty and rude to wind a delicate wire like that with confidence i think

It's like an electric stirling engine car! Something about it is just very charming, I also have to say to say that I love the visual design language of this project. I love me some function informed aesthetics!
The little setup at 9:30 is brilliant! I would have love to have that during my early physics classes
Tom I am really glad you dared to try the method of using peltier modules. Most people are probably not aware that they can also be used like solar panels. With a lot of fine tuning of the coil size and capacitors etc. a much more efficient device could be achieved.
LASERSABER! Man is the master of efficiency. Extracting energy from the air and ambient temperature changes.
I love your desings and how you present them on videos, cool work my dude.
Wow, what an excellent video! I love the car experiments. Thank you for sharing.
Really engaging study. Thank you.
Upscale it and ride it?
There are versions of lasersaber's motor that have been running for years, so a really nice demo of what you can do with electricity and kinetic energy
cool concept and video. I’m glad you included the end explanation to “debunk” the seeming paradox of the push test. But I’m surprised you didn’t catch and correct your earlier comment about it not going as far as you pushed it because it’s “not 100% efficient.” That would have been a good learning moment to explain that a 100% efficient car would go infinitely far, completely independent of how far you pushed. And with your not perfect efficiency. the distance traveled has more to do with how hard you push over the distance, not just the distance you push. Anyway, thanks for the upload and thanks for mot making a perpetual motion device.
Really fun to watch. Thank you!
build this on your bicycle, can charge when cycling and it keeps going if you want to take a little brake.
I doubt it will keep going if he brakes though! ;)
I think he already made a capacitor bike
As pointed in the video, it would go for a bit, while you are resting, but this energy doesn't come from nowhere. You would feel more resistance when cycling. In the end you would be more tired to drive the same distance, as some energy would be lost as heat. Also I believe he did "supercapacitor bike"
Break
If it's less efficient than a flywheel then it won't really work since he already showed that flywheel bikes are impractical
I wonder if adding a capacitor to the peltier car would make a difference. Like storing the power from the peltier when the reed switch isn't engaged and releasing it when it is
8:30 the one with the motor is requiring more force to push it which isn’t noticeable since one stick is used to push them both. That’s where the extra energy comes from.
The final result seems like a contraption from a studio gibly film, amazeing!
Very cool.would be interesting to use the mechanical power to work a clock mechanism. Maybe solar power to store up energy during the day to run through the night
Really amazing designs and valuable explanations, thanks!
The engineering work put in this video is impressive.
This is why I love the internet. I've been dreaming of this mechanism for the past several months, even started drawing up some schematics. And lo! Someone's done the hard work for me lol
I don't know what the hours of work vs minutes of video ratio is for this one but it seems high. Super cool stuff.
This is also a good analogy for the faster than wind (wind only powered cart). In that case the energy is stored as pressure differential on each side of the propeller instead of energy being stored in a capacitor.
"the energy is stored as pressure differential on each side of the propeller" -- Would you describe a piston-engine driven airplane the same way? For a piston-engine driven airplane, I would say the energy is stored in the fuel.The small pressure difference from one side of the propeller to the other stores a trivial amount of energy. Shut the engine off and pressure difference (AKA thrust) disappears very quickly. The same is true for a downwind-faster-than-the-wind cart. The propeller requires a continuous input of power to produce thrust. This power comes from the wheels that are in contact with the ground.
@@andrewsnow7386 Yes the amount of stored energy is very small. See my last video where two propellers of about 0.1m^2 swept area moving air at 3.2m/s have less than 2 Joules of stored energy. I demonstrated in my video exactly why that sort of vehicle can exceed wind speed and why that is just temporary proportional with the amount of stored energy.
@@andrewsnow7386Also, check out autorotation aircrafts. Some experimental models employ the same principle. They still get engines, others are part glider part autorotation, but the principle electrodacus said is better employed on those.
@@electrodacus I watched your video twice, and it's not clear to me what you are trying to demonstrate. You end with the conclusion: "It's clearly not powered by wind power when above wind speed." We need to parse this before I can say if we agree. Are you saying that the difference in motion between your treadmill and the air is not powering your cart? Or are you saying that your experiment has no wind (that is the air is static in the room) and since the wind speed is zero, it can't be powering anything? I'm fairly sure you are claiming the first, in which case your own experiment proves you wrong. Consider 2:20 in the video. Using the reference frame of the belt on the treadmill, the cart is moving forward at 5.33 m/s when you are restraining it with a force of Fnet using your hand. Since the cart can travel at 5.33 m/s and still have a positive Fnet, it must have a speed greater than 5.33 m/s where Fnet = 0. The cart must have an equilibrium speed faster than the wind for Fnet to equal zero. If so, then the cart could be powered by the "wind" indefinitely at speed greater than the wind.
@@andrewsnow7386 Yes air speed in the room is zero thus there is no wind power. Same way as there is no wind power available to a vehicle traveling direct down wind faster than wind. The cart is powered by the treadmill while restricted by hand (is just a treadmill powered fan not a vehicle in that case). When hand is removed the cart accelerates forward powered by the stored pressure differential for about 8 seconds. After those 8 seconds the vehicle will start to decelerate (negative acceleration) as it is powered by the treadmill and if the treadmill was not limited in length the vehicle speed will decrease all the way below wind speed where the steady state will be. So steady state is below wind speed and not above wind speed. The video demonstrate that by showing that after 8 seconds when cart acceleration the cart is not at steady state but acceleration becomes negative and so steady state of the setup will be when vehicle is below wind speed. I also show why the cart accelerate against the treadmill direction (stored energy in the form of pressure differential or put in a different way air potential kinetic energy) and I'm able to precisely predict that cart will only accelerate to the right for 8 seconds using that less than 2 Joule of stored energy at the start of the experiment. So Fnet will be zero twice. First time after 8 seconds from the time cart is released and second time after probably 10 to 12 seconds but treadmill was only long enough to allow another 5 seconds of travel. Still is clear that Fnet was positive starting to decrease from the moment cart was released from hand got to zero after 8 seconds and then became negative for the next 5 seconds before experiment ends. With 5.33m/s the cart got to around half the treadmill before starting to decelerate while at 5.66m/s the cart will have had more initial stored energy and so it will have started to decelerate only when it was almost at the end of the treadmill. If treadmill speed was below 5m/s then cart will not have enough stored energy to accelerate at all to the right and thus it will directly start to move to the left (in the direction that treadmill moves).
absolutely wonderful!
This is by far my favorite video of yours!
This design is pretty cool to see. Thanks for the physics explanations too btw!

Go. Away.
There's something about that final car that I just find so adorable! I love it
so glad to see you finally got some proper THIN wire!! you can get the stuff used for guitar pickups for good quality
Wow. That candle powered generator is really a smart idea but what about using a torch to heat it up? I know this would melt probally but if there was a heat resistant one that can survive that big heat it would be really cool to see a torch powered car. You could cooldown the heatsink with liquid nitrogen or something like that
I didn't think a more intense flame would gain you much. The issue is absorbing all the energy from the flame. A heatsink on the bottom would probably be better, or some kind of nozzle that would spread the fire/heat out more.
when he added more knots to the candle it produced more electricity. so maybe im not an scientist but this for me means that more heat = more electricity.
@@prodjament Lots of heat escape around it in form of hot air, so a heatsink on the hot side would have made an improvement, but the brute force approach is a tried and true method
The main issue is that peltiers are not very efficient. Adding the ice is like adding a battery. It is stored energy in the form of solid water. Adding heat helps but you have to dissipate heat from the cold side just as much to maintain a steady flow of energy. A larger heat sink on the cold side and getting the bike moving faster would allow more airflow to dissipate the heat. There is a heat limit to these devices, where the internal solder starts to break down.
@@prodjament It's more complicated than that. It's the difference between upper and lower plate. The more difference the better. But too much heat on the bottom might also heat the upper plate and ruin the balance.
soooooo you’ve built an electric stirling engine - that is INCREDIBLY funny!
Unfortunately, it is not. Stirling engine is mainly based on its pistons and expansion/compression of gas as it's heated or cooled. It uses similar cycle to a Carnot engine (which is its main advantage). However, if that will cheer you up, Stirling engine could be used to power a machinery with heat and cold - with the heat coming from nuclear breakdown of certain isotopes and cold - from near-0 temperatures of vacuum of space - and that's why it's used e.g. for deep space probes. The car here uses what's called a thermoelectric generator - and is an alternative for using Stirling engine for the same thing (just like e.g. gasoline car is an alternative to Diesel car).
This video is such a great example of how great it is to live in the 3D printed prototyping era.
This is brilliant because this could be compared to that kit that converts all electrical components and circuits into a system of cogs and chains that you can link together! Because this is the same as the wind up cars but instead of storing mechanical energy using a mechanical advantage, you’re storing electrical energy with that mechanical(/electrical) advantage! So cool
build this on your bicycle, can charge when cycling and it keeps going if you want to take a little brake
The problem is it would be harder to pedal than a normal bike, meaning you get tired faster. You would perhaps for less time, but actually use more energy since some is lost converting it to and from electricity.
the same issue accurs with the bikes that have a generator and engine instead of a chain or belt, you lose alot of energy but there is alot of advantages such as no oily bits and whould be better for services that want to perform little to no maintenance@@ADBBuild
i refuse to believe you are secretly employed as a toy maker somewhere...
I refuse to believe that he isnt 😂
This is brilliant. Honestly.
This was really cool! I'll probably try to make it myself. Great Video!!!
I'd be really disappointed if any car wasn't able to travel farther than it is pushed. I generally aim for my car to have a mechanical efficiency above 0% lol
This Car Travels Further Than you Push It.
You could use it, as well as the heated air with the right design, to candle holders with moving elements. It may have some small models moving around, or a carillon playing without any batteries, just because you put a candle in it
I think I could get this to work in a full size car. What you need is a bungy cord and grappling hook on the front of the car. When you want to start, hook it around a lamp post, get in and release the handbrake, off you go. You just need to remember to park by a lamp post when you stop.
this kind of reminds me of a prototype car that Volvo were playing with just before being brought by Geely. They had a conventional front wheel drive car with a rear wheel flywheel generator / mechanical motor on the rear axle. The idea was that a slipping clutch was used to gradually bring the flywheel up to speed whilst driving along then when pulling away, the clutch would disengage quickly dumping the flywheel energy into the rear wheels assisting the petrol engine getting up to speed. I guess it didnt work as they stopped development on it but it was a simple sytem with an electronic clutch
Never heard about it. The system using a CVT instead (that they experimented with when owned by Geely) to me sounds as a way more reasonable way of using a flywheel as energy storage.
@@TarenGarond KZhead won’t allow me to post links but if you google Volvo mechanical kers you will see a few articles

I could watch your projects all day 🥰
Try making an airplane that has two propellers, one for power generation and the other for propulsion
Sadly would not work.
In this house, we _obey_ the laws of thermodynamics! The generator prop would, by design, cause massive drag as it generates power. It relies on wind resistance to spin the prop. It wouldn't even work as a range extender, you can't get more power out of a generator than you put in under any circumstances.
thats just beautiful!
love your videos and also i love comparing electrical energy as water related things, so thinking of it as pumping water to a height and then letting it flow is usefull here
Wow this is amazing 🎉🎉🎉 congrats keep the good work up
