Japan is progressing with the OHISAMA project to develop space-based solar power transmission, aiming for a demonstration in fiscal 2025. The initiative, involving Kyoto University and the Japan Aerospace Exploration Agency, seeks to capture solar energy in orbit and transmit it to Earth as microwaves, addressing limitations of terrestrial solar energy. Despite challenges in construction, efficiency, and safety, this project aligns with Japan's carbon neutrality goals by 2050.
