Also, as far as the solar satellites go, a far simpler solution is to use the same sun-bathed areas as collectors instead of receivers. Simple sterling engines, using water vapor as the working fluid and an array of mirrors to vaporize said water, can be made cost effectively at ~$1k with current tech for a station of ~2 m^2. Multiply a lot of those together and you make an astonishingly large amount of power, all without the need for fancy satellites, control systems, possible weaponization, etc, and at extremely low cost relative to $186B in 1980s dollars (i.e. trillions in today's). However, it's so simple that it gets overlooked: the most elegant and best solution is often the simplest and crudest, not the fanciest and highest-tech.
