Aren't these more like technical challenges, rather than theoretical
signs?
The cogging is OK, but if you start out at 100% efficiency then
anything that goes to heat subtracts from that. The problem is to
find a source of energy, a way to start out at over 100% efficiency.
Energy is all around us, in the form of the ZPF, and bottled up in
nuclei. The trick is finding a way to tap it.
