In 2020 the U.S. Naval Research Lab launched a module on an orbital test vehicle, to test solar hardware in space conditions.
That was testing solar panel tech that's used to power satellites, not stuff on the ground.
This year Caltech electrical engineering professor led a team that successfully launched a 30-centimeter prototype equipped with transmitters — and successfully beamed detectable energy down to earth.
This is otherwise known as a radio transmitter and a rectifying antenna. You can buy them at Radioshack. Well, no you can't. But you could buy them at Radioshack back when Radioshack sold actual radio electronics equipment.
In June the U.K. government announced over $5 million in funding to universities and tech companies "to drive forward innovation" in the space-based solar sector.
That's a Tory grift to funnel money to supporters. Also known as a kickback.
The U.S. Air Force Research Lab plans to launch a small demonstrator in 2025.
From the article: "The goal of SOLARIS is to prepare the ground for a possible decision in 2025 on a full development programme by establishing the technical, political and programmatic viability of Space-Based Solar Power for terrestrial clean energy needs."
It's a proposal to begin a fact finding committee to organize an investigation into the possibility of a research program. Which is bureaucratic-speak for, "This is how we waste money for twelve years then say nothing came of it."
Europe's its Solaris program aims to prove "the technical and political viability of space-based solar, in preparation for a possible decision in 2025 to launch a full development program."
Same as above.
One Chinese spacecraft designer and manufacturer hopes to send a solar satellite into low orbit in 2028 and high orbit by 2030, according to a 2022 South China Morning News report.
This is just a scam. It might actually just be propaganda; it might just be a scam without a scam.
