"2025: Japanese Satellite to Transmit Solar Power to Earth"

Japan is set to launch a small satellite in 2025 to demonstrate the transmission of solar power from space to Earth, marking a significant step towards a potential space-based solar power station. The satellite will wirelessly transmit energy from low Earth orbit using a photovoltaic panel and microwaves, with the mission part of a project called OHISAMA. While the concept of space-based solar power was once considered impractical and costly, recent technological advances and the urgency to decarbonize the world's power supply have renewed interest in the idea, although some challenges and concerns remain.
