(Phys.org) -- Artemis Innovation Management Solutions has been given some seed money by NASA to look deeper into a project the company first proposed last summer; namely, building a satellite that could collect energy from the sun and beam it back down to Earth to add to the electrical grid. Building such a satellite has been bantered about for several decades by various groups and scientists, but until now, no one had come up with a design that would work given all the constraints of the time. But now, an idea proposed by longtime NASA engineer John Mankins, now with Artemis, has clearly created enough interest within NASA that some money to investigate the idea is being offered.

The question I have to ask is why? The sun delivers as much energy to earths surface in a few hours that we have consumed in a century.

I saw this some time ago:

"New solar product captures up to 95 percent of light energy"

Not quite ready for production.

Jerry Pournelle. Well known science fiction writer who worked for the U.S. govt. and NASA at one time. He has a few very solid ideas on that, space to earth weaponry and such. Clarke claimed to have invented the geosync satellite idea (but did not by a number of years). Pournelle, OTOH, pretty much DID invent the idea of satellite power stations.

And they are saying NASA gave them "the seed money". Makes me think they might do some more if the first one is successful.

Would it be feasible to use a satellite to capture and store helium 3 from the solar wind?

"... Extracting helium-3 from the moon and returning it to Earth would, of course, be difficult, but the potential rewards would be staggering for those who embarked upon this venture. Helium-3 could help free the United States--and the world--from dependence on fossil fuels...
