Ambitious plans for space-based solar power face steep costs and engineering hurdles, making them far less practical than rapidly advancing terrestrial renewables. https://www.japantimes.co.jp/commentary/2026/05/26/world/solar-in-space/?utm_medium=Social&utm_source=mastodon #commentary #worldnews #meta #overviewenergy #spacex #space #solar #internationalspacestation #spaceforce #starlink #blueorigin #jeffbezos #amazon #starcloud #alphabet #china #elonmusk #satellites

Solar in space is a solution in search of a problem

The thinking behind space solar makes some sense: The sun doesn't always shine on Earth, which means solar panels on the ground aren't always gathering energy.

qwant news | Mark Zuckerberg's Meta to power AI data centres from space in 'transformative' move

AI generated summary, Read the full article for complete information.

Meta is partnering with Overview Energy to launch 1,000 solar‑panel‑equipped satellites that will collect sunlight in space and beam the converted energy back to Earth as low‑intensity infrared, providing up to one gigawatt—enough to power roughly 750,000 homes—for its AI data centres. The plan, announced by Meta’s Vice President of Energy Nat Sahlstrom, aims to supply clean, reliable power without stressing U.S. electricity grids, with a demonstration satellite slated for launch in 2028 and commercial power generation beginning around 2030. Similar space‑solar initiatives are also being pursued by SpaceX, Blue Origin and Google.

Researchers Beam Wireless Power From a Moving Airplane
Flight marked first time power has been beamed from a moving aircraft. It was conducted by Virginia-based #startup #OverviewEnergy.
Greater purpose of flight was to demonstrate feasibility of a much grander ambition: to beam power from #space to Earth. Overview plans to launch satellites into geosynchronous orbit to collect unfiltered #solar energy where the sun never sets and then beam this abundance back to humanity

Growing efficiencies of near-infrared #lasers make them preferable over #microwaves, allowing the transmission antenna on the spacecraft to be scaled down from hundreds of meters across to about half a meter 📏. #OverviewEnergy successfully tested a system that transmitted “multiple thousands of watts” of power using a near-infrared laser from an aircraft flying at an altitude of 5,000 meters to a receiver on the ground https://spacenews.com/overview-energy-demonstrates-technologies-for-space-solar-power/
