One nice thing about the internet is that grand, headline-making ideas are made reasonably permanent: they forever orbit our augmented consciousness as optimistic little data packets that occasionally drift again into focus. Which is a convoluted way of saying that the internet keeps humanity's biggest dreams on file.
Wrapping the moon in a solar paneled ribbon that beams power back to earth is one such dream.
Back in 2011, the internet recorded this dream: the Shimizu corporation, a major Japanese construction company, announced it had plans to send robots to the moon to mine ore for, construct, and operate a massive solar array that would stretch across its entire diameter. That giant solar ribbon would beam energy back to Earth as microwaves, and be converted into electricity at transmission stations. Which would mean enough clean, sustainable power to run the planet, more or less.
It's dubbed, for the obvious reasons, the Luna Ring.
