I'd love to see what amount of that energy they expect to get back to earth as for what I understand is the the efficiencies for sending energy back like this is atrocious.

Even if it's an absurdly low % of energy collected, guess what, it's constant and practically infinite on a human timescale

NASA has already done research on efficiency, cost etc

Then they can just buld a bigger one. For free energy it is worth scrapping a few cruse ships worth of steel. The savings on decreased lung cancer would more than pay for it.
