Yeah, microwaves are right out. Lasers, maybe, but lasers that can focus so closely qualify as offensive weapons. Generally, less-focused lasers, picked up by nighttime solar farms that absorb sunlight directly in the daytime, are a much more likely medium for orbital power than microwaves. Monochromatic light can be converted to electrical power with much higher efficiency than can blackbody solar radiation. Lasers producing no greater intensity than sunlight worry people less than microwave radiation.
