Don't be silly. Even if you obtained 100% efficiency, which is impossible in an atmosphere, the drag of the generator would make it stop. They beauty of this device is low friction (drag).

I had one of these as a kid. O.k., it's not perpetual motion, but pretty darn close (and zero emmissions!) I have to wonder, how big of a drinking bird would be necessary to drive a turbine powerful enough to power a single average American home? And what would it cost, taking into account economies of scale, to make ten million of these?

But geek people know the truth behind it: magic. or just a thermodynamic machine designed to amuse us with simple minds. you decide.
