> However, the biggest problem is the massive losses caused by changing laser light to electricity and back across multiple hops. Perhaps they could eliminate this issue by designing the machine at the destination to run directly off of laser light. For example one could imagine a jet engine that swaps out a combustion chamber for a heat exchanger that a high power laser keeps at high temperature. Similarly laser light can be used for remote temperature regulation. Feed it into a photonic circuit for control and computation. Illumination is trivial. The only big power draw I can think of that would be tough to do directly is mechanical actuation.
