I would love to see for an hour. Could this be true perpetual motion?

The more I listen to quantum mechanics the more it sounds like religious nuts. "Oh, we don't know what the qubit is, so that means it's everything, and like 4 or 5 parallel universes too!" it's perpetual motion machines all over again.

Perpetual motion!

@bmacs27

Or, like every other perpetual motion cheater on the internet they just have some form of ducted air blowing across the top of the device.

They ought to have prisons where the prisoners learn remedial science all day long so they can send the perpetual motion nuts along with the dwfttw, young Earth, Intelligent Design, Ayn Rand, and all associated believers along with the climate change deniers there until they can pass a basic science aptitude test.

The world would be a better place.

This is just stupid for so, so many reasons.

I upvoted so that anyone with a brain could have a laugh at those who believe in perpetual motion.

The wikipedia article on magnets is a good place to start. Magnets can lose their magnetism, but that's not the same as saying they have energy in them that's being used up like a battery.

If you stand next to a large lump of clay and then step onto the clay you've gained some potential energy. The taller the lump of clay the more potential energy you've gained. However, this energy hasn't come from the clay, you've had to use energy to gain it. It took you more energy to step onto the clay than you gained in potential energy so this couldn't be the basis for a perpetual motor.

Next to the lump of clay is a large bellows attached to a balloon. You step off the clay onto the bellows. You drop down to ground level and pump up the balloon a bit. You can repeat this process over and over until the balloon is pumped up. However, each time you step onto the clay it sags a bit and you're not so high up. After a while if you do this for long enough the clay will be well trodden down and each time you step off the clay onto the bellows it will have hardly any effect. The clay has lost it's ability to help you pump up the balloon. It's lost it's height. But at no point did it give you any energy to pump up the balloon. You used your own energy to step up onto the clay to give yourself the potential energy, which you then converted to kinetic energy by stepping onto the bellows and pumping up the balloon.

This is exactly the same as a magnet losing it's magnetism. It's not like a battery losing power by powering something else. There's no energy in a magnet. It never gives energy to anything else. Like a drive shaft doesn't power a car, it just helps move the energy from the engine to the wheels.

Magnets fool everyone by working at a distance. Everything else we deal with in a physical way has to touch something else to affect it. You can't get a nail into wood without physically hitting it with a hammer. Magnets confuse us and that makes it easy for scammers with their perpetual motion devices to make us believe things that aren't true. We don't have the right wiring to easily figure out what's going on intuitively.

Magnets simply don't work how you think they do, or how the maker of this video wants you to believe they do.

Applying the oversimplified version of laws that you learned in early physics classes to reality can often leave you in stunned silence when reality seems to defy them. Things like the dimples on golf balls or sailing ships moving upwind are classic examples of things that you wouldn't expect to even be conceivable unless you saw it in action.


Conceivable or not, none of the things you mentioned break the first law of thermodynamics.

One situation where the system could work would be if the car was driving into a strong headwind. This would give an energy input into the system. It could be perhaps developed to extend the blades if there is a strong enough headwind, and retract them if there isn't, but if there is no breeze, there will be a net loss from using the blades.

If the car is driving through stationary air then the air it's passing through will have no kinetic energy. After passing over the blades the air will be moving, it will have gained kinetic energy. That energy will have been taken from the car. It's as simple as that. No complicated equations needed. You'd need the complicated equations if you wanted to calculate exactly how much energy is lost, but you don't need them to see that energy would be lost.

If wind is factored into it then the air already has kinetic energy, which would be extracted by the fan, but the wind would be and external source of energy (in the same way that a wind turbine isn't in any way a perpetual motion device, it's obvious where the energy is coming from).

Capitalism at work in China. 1 inverter living his dream.

Socialism at work in America. In America our government forces GM to produce the Chevy Volt. Very little people buy them since they cost $100,000. The buyer pays $40K and the Tax payer eats the $60K.


"Capitalism at work in China. 1 inverter conman living his dream."

Fixed that for ya.

This is just another perpetual motion machine. You cannot violate the second law of thermodynamics, which would be required for this to work.

I think it's more likely that this system extends the drive time of whatever battery cells he has installed in the thing. It's not that he's getting free energy, it's just that at 40 the system is going fast enough that even though there's a net loss, the additional energy stored in the batteries gives a longer running time. I think that's just about all that there is here.

Agreed. I'd downvote the video if I could. People, if you're in doubt, think of it this way - if the fan could generate more power than the loss of pushing it, then you could just keep adding more fans until it becomes a perpetual motion machine..



Problem, nothing happens at 40 miles an hour in physics for a decrease wind resistance and drag. If anything, the faster you go, the more of a problem wind becomes. There is no possible way that this is extending his drive time. This is exactly equal to holding your hand out the window. If you could turn that blockage into electricity, it will always be less energy than the amount of momentum it sapped via drag. Or else ALL CARS WOULD ALREADY DO THIS! The reason you don't is because it doesn't work.

A simple instance where something like this IS used is the emergency ram air turbine for jumbo jets. When there is a complete loss of power, a ram air turbine drops down to generate emergency power for the hydraulic systems. This increases drag, but it is so small that it isn't a problem. But it is also why air planes don't have windmills on them, anything you use to block the wind is slowing you down more than any recoverable amount of energy via electric conservation of kinetic energy. This is physics 101, entropy, it's a bitch!

Now, if he compressed the incoming air, added a combustion chamber with kerosene or gasoline, then he would have himself a turbine engine for his car, but now, he just has a lesson in why physics is hard.

I think it's more likely that this system extends the drive time of whatever battery cells he has installed in the thing. It's not that he's getting free energy, it's just that at 40 the system is going fast enough that even though there's a net loss, the additional energy stored in the batteries gives a longer running time.
