It'll be a breakthrough when it is done. The idea isn't new. It is a shame America can no longer undertake these projects.

It will be interesting to see if it gets built. The economics has always been the sticking point for solar powered satellites. There were seriously studied during the 1970s. To get the economics to work, mining the Moon was felt to be needed. Manufacturing would be done by a space colony at L5. Which, itself would be built with Moon materials. Realize that an SPS is going to be huge, kilometer scale. I don't know how they plan to get the economics to work. Even if SpaceX can make their boosters fully reusable, the costs are still going to be high.
