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 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.

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.

@@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.
@electrodacus8 ай бұрын
@@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).

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.

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.

Awesome video! Interesting point to note is that using the Lagrange for electrical systems the capacitor can be equivalently thought of as a spring. Thus, an equivalent system would actually be one where a spring is coupled with the free-wheel , edit: so long as (k/2) = (1/2C).

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.

When using the ruler to push both cars you are adding friction to the back wheels during the push, since the front wheel is still free to spin the capacitor car has an advantage as it is able to gain energy during that time.

I have a suggestion for you. Use steam to heat it. Take a small water tank and connect a thin copper pipe to the tank, which is wound into a spiral. The tea light heats the water tank, the steam rises into the spiral and this is positioned so that it is also heated by the tea light. The now super hot steam should develop extremely usable heat to melt your heating plate. The force alone that is created when the steam expands is like the high pressure of a jet nozzle. You can also use simple sawdust instead of water to generate wood gas with the tea light, which is then heated to a super high temperature in the spiral.

It's a given that perpetual motion is not possible in our universe due to the entropy induced energy loss, but watching your tinkering with various ways of capturing, converting and using several manifestations of energy concurrently, you do make it look like you're awfully close to achieving perpetual motion....and this where science can be cleverly manipulated to trick our minds into believing the impossible. Well done.

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.

the carbon buildup on the bottom of the pad is definitely insulating it a decent amount from the candle heat, maybe add some o2 circulation somehow or use fully mixed butane if that doesnt burn the thing completely and i think youd get some pretty decent speeds ngl. fun stuff.

"ICE powered", usually people mean it as "Internal Combustion Engine", but in your case it’s really about frozen water PLUS an external combution engine. The candle design reminds me of the candle powered "pop-pop boats" as seen in Ponyo. They work on a different principle, though.

I don't know about the reed switch, I've managed to convince myself that optical would be more reliable. I'd run it from a small battery so it didn't use power from the working circuit. Making a coil gun made me realize how critical the riming is for these type of things. I've played with this sort of thing quite a bit. The only thing I've discovered is that they seldom work as well as I imagined it would. Good vid m8, thanks. 🤔😃

Cool car! I feel like there is a variable in how long you push them, adding force over time to charge the capacitor. (Could instantaneous force be applied to the cars?) The flywheel is increasing resistance to the motion on the "driven" axle. So the idea that the car drives further with capacitor than without is not applicable to real life, because we wouldn't connect a flywheel if it wasn't for the capacitor. It would be awesome to see you take off the flywheel and have a free rolling axle and make the ballast heavier to accommodate and THEN add force (instant if possible) and see the result!

Brilliant. I love the synergy of the smart new scientists and engineers with the new toys available such as Lithium Ion batteries, 3D printing, controller boards, Python. Leaves us old guys in the dust, as it should be....Don't forget that the resistance of the freewheel to motion is non-linear to the rotational speed of the freewheel. These devices would be better tested in a vacuum, a bit harder.

What makes this video stand out is the actual proper analysis of where that "free energy" actually came from. So many free energy nutters essentially use devices like this, though in most cases they are either completely incompetent to calculate the actual efficiency or are a straight out fraud. The force difference wouldn't be clear for most people and the fact that during the "push phase" the capacitor accumulates additional energy. When the push stops both cars had the same kinetic energy, but the electric one had additional energy stored i the capacitor. I'm wondering since charging the battery of an electric car has a nasty efficiency curve, if it would help to add some large capacitor banks for the generative braking to buffer the energy. Especially for city stop and go driving when the battery is almost fully charged could provide some benefits as most of the energy conversion (elec. kinetic) would be stored in the capacitors if possible. Though since we talk about quite some amps and cycles, the question is how long those would last. Capacitors also have a similar efficiency curve. However they would most of the time be empty during normal drive so they should be able to capture quite some energy efficiently. Maybe with some clever step up power converters the exess energy in the capacitors could slowly be put back in the battery i the most efficient way. So this would be like those hybrid HDDs which have a small built-in SSD to buffer reads and writes in the SSD to increase the performance.

A smaller front wheel would have done the same as the gearing an o ring works well as a tire. The pelter unit from a fridge will run the 12 volt fan motor when unpluged and for the higher power has many units connected together you can get the complete fridge from a garage sale for $5 box in the ice to stop the water running down to the hot side.
