Beaming Solar Power From Space to Earth Is a Sci-Fi Dream That's Getti

Beaming Solar Power From Space to Earth Is a Sci-Fi Dream That's Getting Closer
The U.S. military deployed a solar-harvesting test module into space in May. Will space-based solar power ever work, and what will it take?

While the solar industry is constantly finding new ways to tap into this energy from Earth’s surface, some visionaries have their eyes on an even bigger stellar prize: space-based solar power (SSP).

This potential power source would involve launching sophisticated machinery into space to harvest sunlight in an environment where the Sun never sets. The energy would then be wirelessly beamed back down to Earth in the form of microwave or laser emissions that can be converted to electricity at ground stations.

Theoretically, space-based solar power could provide a constant source of green, sustainable energy to the entire planet, day or night, which has made it an attractive option in discussions about how to decarbonize the global energy system in the future.
