Growing efficiencies of near-infrared #lasers make them preferable over #microwaves, allowing the transmission antenna on the spacecraft to be scaled down from hundreds of meters across to about half a meter 📏. #OverviewEnergy successfully tested a system that transmitted “multiple thousands of watts” of power using a near-infrared laser from an aircraft flying at an altitude of 5,000 meters to a receiver on the ground https://spacenews.com/overview-energy-demonstrates-technologies-for-space-solar-power/
