Space-based solar power (SBSP) captures solar energy in geostationary orbit where sunlight is available nearly 24/7 and beams it to Earth via microwave or laser. While technically ambitious, the concept has received renewed investment from governments and startups as a potential source of baseload clean energy. Falling launch costs are improving the economic case, and several demonstration missions are planned or underway.
