: Your theory may be... flawed. These machines could make thing happen at
: 100% efficiency.
100% efficieny is provably impossible. I believe the maximum possible efficiency is around 70% (look up the Carnot refrigerator).
: It is the future. Energy could also be captured.
: ...and... energy is never lost. Einstine states that energy is equal to
: mass times a constant squared. Energy is CONSERVED. Not lost.
No, he said that energy cannot be destroyed. Energy can always be converted to a form that cannot be used to perform useful work, or a form from which it cannot be unconverted (like heating of objects through friction). Entropy never decreases.
