Meanwhile, the Japanese are working on similar technology that will make an attempt to beam solar energy from space in 2025.

In an amazing breakthrough for energy development, scientists from the California Institute of Technology have successfully demonstrated that solar energy can be collected in space and beamed down to Earth in a seemingly endless supply.

    The institution announced Thursday a power signal transmitted by a small demonstration unit orbiting 550 kilometers above the planet was recently detected by a receiver on the rooftop of a laboratory on Caltech’s Pasadena campus.

    Ali Hajimiri, Bren professor of electrical engineering and one of two co-directors on the project, confirmed transmission occurred May 22.

“It took a few moments for it to sink in, then everybody got really excited,” he said in an interview Thursday. “This technology for wireless energy transfer can have a tremendous impact on lives, both on Earth and in space.”

The 50-kilogram Space Solar Power Demonstrator (SSPD-1) is testing three key technologies that would make it possible to convert sunlight into electrical energy and then send it in the form of microwaves to receivers anywhere on the planet.

Cool but it won't cook the atmosphere?

Cool but it won't cook the atmosphere?

Interesting question which, apparently (according to a quickie search) has not been researched.  See, e.g., this article (author could not find any research on whether terrestial rf sources could be heating the atmosphere):  https://www.21stcentech.com/micro-radio-waves-contributor-global-warming

I would note that the author of that article has made a classic error of logic - assuming that an absence of evidence is evidence of absence.
