US Congress Breaks Ground on Space-Based Solar Power: A Small but Significant Victory for Space Exploration Enthusiasts
I didn’t see any mention of how they actually get the power down to earth. Really long cable maybe?
Last year, at the International Space Development Conference, a NASA official said the agency had begun a short-term study evaluating the prospects of space-based solar power. This was the agency’s first real look at the subject in about two decades. However, that study has not been released publicly, as there were apparently some policy concerns about the first draft. The revised study may finally be released in late June or July.
I imagine it would be something like the wireless energy beaming tech in this TED talk: https://www.youtube.com/watch?v=RxrB7PDLJ18
