Beaming 24/7 solar… from space

It’s the highest-intensity solar power you can get. It’s available 24/7. And you can send it anywhere on earth. All you need to do is launch a ten-by-ten kilometer array of solar panels into geosynchronous orbit, capture solar energy, and beam it to earth using a massive antenna array. Then set up a receiver a few kilometers in diameter on earth to collect that power and send it to the grid.  Sound like science fiction? You wouldn’t be far off (looking at you, Isaac Asimov). But the reality is that Caltech, the U.S. Naval Research Laboratory, and the Japanese Space Agency are all working on the idea. Recent developments in space tech warrant some cautious optimism about space-based solar. Space X has pioneered reusable rockets that have dramatically reduced the cost of launches. And mass production of satellites has brought down the cost of hardware, too. So how would space-based solar actually work? And what would it take to commercialize it? In this episode, Shayle talks to Sanjay Vijendran, lead for the SOLARIS initiative on space-based solar power at the European Space Agency. He argues that space-based solar is much closer to commercialization than nuclear fusion, which garners a lot more attention and funding. They cover topics like: The four main components: the launch, the solar panels, the antenna, and the receiver on earth Where we need additional research, including beaming power at greater distance and scale, plus power beaming safety What it might feel like if you stood under the beam The target launch costs the industry would need to reach for viability Pilot projects happening right now Recommended Resources: The Verge: Space-based solar power is having its moment in the sun Science: Space-based solar power is getting serious—can it solve Earth’s energy woes?
