Japan has embarked on a groundbreaking renewable energy initiative known as the OHISAMA Project, led by the Japan Space Systems Corporation (JSPACE), with support from the Japanese government.
The goal is to wirelessly transmit solar energy from space to Earth, allowing for uninterrupted solar power — even at night.
According to Al Arabiya.net and Gizmochina, research began in 2023 and has since reached a critical milestone. The project plans to launch a 180-kilogram satellite into low Earth orbit at an altitude of 400 kilometers.
Equipped with two-square-meter solar panels, the satellite will harvest solar energy and transmit it as GHz-frequency electromagnetic waves to a receiving station in Suwa, Japan.
The main challenge lies in precision targeting, not safety—the beam’s radiation is comparable to regular sunlight. The satellite must successfully deliver the energy to a 40-kilometer-wide receiving zone while traveling at 28,000 km/h.
If successful, this project can revolutionize sustainable energy by overcoming the limitations of Earth-based solar systems, such as weather and darkness, and drastically reduce dependence on fossil fuels.
