that fucking asian dude's device, magical 5000+% efficiency while the belt is wasting energy wobbling like crazy
how does he cause malfunctions with such great comedic timing? :v:
I believed in free energy. When I was a fucking kid. Whoever doesn't know this basic ass law that was taught in highschool, deserves to get scammed.
Once when I tried to sleep, I came up with this idea for a perpetuum mobile:

My thinking behind it was this:
The ball rolls onto the left weight block. Since it is now slightly heavier than the one on the right it slowly moves downwards, powering the generator. At the bottom, the left block loads the spring with it's weight and some mechanism locks it in place. The ball rolls off to the left and stops on the spring part. Since the left block is now slightly lighter again, the right weight pulls the left one up, powering the generator again. When the right block hits the bottom, it triggers some kind of kinetic spring release mechanism which launches the ball upwards to it's starting position.
Of course this is not going to work otherwise someone would already have invented it. But I wanted to share with you anyway to laught at it. I guess the spring part is what would cause it to not work, even if you adjusted all weight values. I have never looked into what force springs need and create upon release.

That's the error here. Aside from the spring only receiving [I]b[/I] to be loaded but launching [I]2b[/I], you also neglected the kinetic energy needed to lift it. (It's very close to being proportional to [I]mass * height difference[/I] in simple cases.)
Essentially, and assuming there's no friction whatsoever, the spring contraption would be loaded with [I]b * c[/I] energy, but it needs [I]2b * d[/I] to launch it back up. [I]c << d[/I] too in this case, since the spring only gets loaded at the very end and there's some additional loss due to the slopes in-between.
