Could solar power from space actually work?

It sounds like something straight out of science fiction: giant solar panels floating in space, beaming energy back down to Earth. Companies like Meta and space agencies in Japan are taking the idea seriously, hoping it could help power growing energy demands. Supporters say space-based solar could deliver constant, around-the-clock clean energy because the sun never stops shining. Critics say the technology is wildly expensive and still far from reality. Matt Galloway speaks with former NASA physicist John C. Mankins and former NASA technology policy chief Charity Weeden about whether this is the future of energy or a very expensive fantasy.
