Space technologies, orbiting solar arraysPublished: 2015-11-19 | Original Article
Space-based energy technologies—things like harvesting hydrogen from the moon to power fuel cells on Earth, or orbiting solar arrays that absorb around-the-clock direct sunlight and beam the energy back down to stations on the ground via radio or microwaves—remain firmly in the realm of science fiction for now.
Both NASA and the U.S. Naval Research Lab are already investing in the technology that could be commercialized in 25 years. The ongoing private space renaissance that has seen companies like SpaceX trim the cost of launching cargo into orbit bodes well for more ambitious projects in space.
Solaren, a southern California-based start-up, has inked a deal to supply Pacific Gas and Electric with space-based solar power by the end of the decade. Stay tuned.
