A small test station still has practical applications as emergency power supplier for localized power outages or, better yet, mobile power supply for people working off the grid. This could have important military applications.
That won't matter (see below). Besides, it's likely that Criswell was being overly optimistic about the focusing abilities of the masers on the Moon; if the microwave beam spreads more than he thinks it will, the mirror orbiting Earth will have to be far larger (quadratic scaling) and therefore far more massive than he thinks.Dude, did you read what I posted? He claims the relay satellite would have 1/300th the mass of a solar power satellite.
As I have said, if the propellants come from Phobos they will be almost free. If the SPS's solar panels and the rockets launching them are made from lunar substances, the cost will be lower than creating a massive solar farm on the Moon (imagine all the highways that will have to be built). Especially if we use robots to assemble the SPS in GEO; it's difficult to imagine robots coping with the complex environment of the lunar surface (anytime soon).Also, what makes you think bringing the satellites from the Moon would be that much cheaper? What you are talking about would require a massive lunar transportation industry. You would need to lift hugely massive solar power satellites from the Moon and carry them all the way to Earth orbit. Which would not be cheap.
