Re: Perpetum Mobile Idea #358



Before you waste your time an money, consider how much work has to be
done to insert anything against the pressure at the bottom of a pipe.
It depends entirely on the height of the pipe and the volume of the
object. A buoyant object will have a large volume relative to water
and require a large amount of work to insert it. It would then float
to the top doing some recoverable and non recoverable work on the
water. It could the fall doing some recoverable work.

Consider recoverable work as positive and every thing else as
negative.

W(falling) + W(buoyant) + W(insertion) + W(heat) + W(friction) = 0, if
you are lucky
