What if there were a way to generate clean solar electricity from space and send it directly to Earth? It sounds like science-fiction, but Caltech engineers are working on ways to collect solar energy on orbiting satellites and wirelessly beam that power back to stations on the ground. The results of their experiments suggest that space-based solar power may have a bright future. But while they\u2019ve been able to show it\u2019s possible on a demonstration satellite, getting power from orbit to Earth is a big challenge. WSJ\u2019s Danny Lewis talks with science journalist Corey S. Powell about what it will take to wirelessly transmit solar energy and how it could transform the future of the grid.\n\n\n\nWhat do you think about the show?
