China builds world-first full-function space solar verification tower
Space solar power just cleared a milestone that researchers once thought was still years away. China’s test tower at Xidian University is the first facility anywhere to run the complete chain — concentrating sunlight, converting it to electricity, and beaming that power wirelessly to a ground receiver — all in one integrated system, completed roughly three years ahead of schedule. It’s a research milestone, not a power plant, but proving the full system works in one place gives scientists a permanent platform to push the technology forward.
