- Question: Have you ever considered using microwaves instead of lasers? My colleague Kevin Parkin has been advocating using microwaves ... millimeter wave systems are extremely sensitive to atmospheric moisture. So you would need to build such a transmitter on a tall mountain. [comment: or maybe on the Moon!]
- So using laser power to power spacecraft anywhere near Earth may one day be feasible. [ comment: interesting]
- Modern lasers have lifetimes measured in decades
