When you are cranking out a 5 GW power plant in a week, you can ignore
financing and inflation. I am sure someone will want to license power
sats, but the first ones will probably be sold outside the US to
countries that don't require licenses. Transmission inside the
rectenna is included. The presumption is that most rectennas will be
put on an existing transmission line.

I note that cost overruns have been the order of the day. So if you
say people are signing up for nuke plants at $5k/kW, why should I
argue with what they will cost when turned on?

Please do note that nuclear plants are the next best (in my opinion)
to massive space based solar power. On the other hand, read the end
