Go back to /b/, seriously. This one isn't even entertaining

I don't get it
If you're implying that the bike is electric and once moving it'll be able to move forever. Then all I have to say is parasitic loss will eventually get it to stop just like every other troll invention,

>> No.2197032

well, if it's a bicycle, and if you rule out the possible opinion claiming that time is money, then this is certainly true.

Free energy.

I have already seen such a device. It won't work.
First: gravity will act in the same way on every ball, even on the one inside the water tank, so gravity will not make the chain move.
Second: You can pull a sphere inside the tank for free, you will have to win a force: gamma*D^2/4*pi*H
Third: H is AT LEAST equal to the number of spheres*D. Let's say that the spheres inside the tank are Z.
Fourth: Water has friction.

The force that pulls the spheres inside the tank towards the top is gamma*V*K, the force that pulls the spheres that enters the tank out is gamma*S*H, but H>Z*D, so, let us sum the forces (gravity sums to zero):
Z*gamma*V - Z*gamma*S*H = Ftot
gamma*( Z*V - Z*S*H) = Ftot
but H is at least = Z*D, so:
gamma*(Z*V - Z^2*S*D) = Ftot < 0 always!

So the chain will turn on the opposite sign, and it will stop in the end due to the friction of the water.

This is the funniest shit ever...
You managed to get trolled by a troll-physics JPG, even though it's posted in what is clearly a troll physics thread. That in itself is amazing, but your explanation is just... incredible.
