Future Signals 2024 - Beam us down, Scotty: space solar power straight to Earth

In 2023, Caltech’s space solar power prototype demonstrated its ability to wirelessly beam power through space and direct a detectable amount of energy towards Earth for the first time. The recent £4.3 million investment by the UK government, China’s ambitious Chasing the Sun project and the US Air Force’s plan for a power-beaming demonstrator from low Earth orbit collectively underscore the global attention on the potential of space-based solar power. Could 2024 be a pivotal year for space-based solar power to spark an energy revolution? --- Every year we identify the signals that could show us the shape of things to come. Read about them here:
