A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

I FUCKING LOVE MIRRORS PLACED AROUND STARS THAT HARNESS ITS ENERGY IN A CLEAN AND EFFICIENT WAY YEAAAAA
I didn’t see any mention of how they actually get the power down to earth. Really long cable maybe?
They did a test with microwave to transmit energy from space to Earth. There is some serious drawback in doing it via microwave though, so I'm curious on how they'll transmit a huge amount of energy without heating up or causing residual damage to the environment.
Yeah seems like there's a general thermodynamics problem with sending a bunch of energy through the atmosphere
And ppl think wind turbines are deadly to birds, imagine a flock flying through a trillion watt microwave beam.

The sun gun or heliobeam is a theoretical orbital weapon, which makes use of a concave mirror mounted on a satellite, to concentrate sunlight onto a small area at the Earth's surface, destroying targets or killing through heat.
Ion canon ready
Most proposals I've seen involve using microwave transmission to a ground-based receiver dish.
I imagine it would be something like the wireless energy beaming tech in this TED talk: https://www.youtube.com/watch?v=RxrB7PDLJ18
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.
Is this because people who grew up playing Sim City 2000 are now in positions of power?
ALL solar is space based
They will try everything else before building wind and solar
Jewish space lasers in the news changed the game.
