Next Big Future  June 6, 2023 Researchers at Caltech launched Space Solar Power Project (SSPD) launched into orbit a prototype to beam power to Earth and that transmitted power from orbit to another receiver in orbit. They confirmed that MAPLE (Microwave Array for Power-transfer Low-orbit Experiment) can transmit power successfully to receivers in space. They programed the array to direct its energy toward Earth. It could survive the trip to space and operate there. Microwave Array for Power-transfer Low-orbit Experiment (MAPLE) and one of the three key experiments within SSPD-1 includes a small window through which the array can beam […]
