Alright /sci/, my friend and I are in an argument. We found this picture in a troll physics thread on /b/. We've been arguing for about 15 minutes now so we decided to just go to /sci/ because you guys are smart. He thinks that this would work if you were to have multiple windmills on the back, and I think that it wouldn't work because windmills don't put out 100% of the energy passed through it. Which one of us is right, /sci/?

energy would be lost in many ways. Physical friction in the drivetrain, aerodynamic drag of the vehicle and electrical resistance to be general.

If you had a strong headwind it might work but the extra weight and drag of the windmill would likely obfuscate any advantage.

Thank you /sci/, and now my friend is saying that it would work if they used the new design of windmill that gained more energy because it was multiple smaller fans on a chord that moves with the wind to reduce drag while gaining energy. He says he referenced Popular Science.

>>	Anonymous Sun Oct 17 03:08:09 2010 No.1907989 >>1907973 Conservation of energy is provably a direct consequence of fundamental laws of classical physics. If any assembly breaks conservation of energy, some specific part must. Which part of his design does not obey classical physics?

>>that moves with the wind to reduce drag while gaining energy

1. it reduces drag, not gets rid of it altogether, so it would still fail.

2. unless the wind is blowing at it it would not "gain" energy, only re-gain the energy that it lost in powering the forward momentum.

>>	Anonymous Sun Oct 17 03:20:09 2010 No.1908021 >>1907997 All the energy can't be re-gained. There will always be mechanical friction in the moving parts and that friction turns some of that energy into heat instead of forward momentum.
