Space-Based Solar Power Moves from Fiction to Feasibility as Global Projects Target 2030s
Space-based solar power (SBSP) is transitioning from a theoretical concept to an active engineering race, with major projects in China, the U.S., the U.K., and Japan targeting test launches within five years. Proponents argue that orbital satellites can harvest sunlight 24/7 without atmospheric interference, potentially meeting Earth's energy needs many times over. While launch costs have dropped significantly due to reusable rockets like SpaceX's Starship, critics remain skeptical about the high initial costs and technical challenges of beaming gigawatts of power to Earth via microwaves or lasers.
