From Sunlight to Socket: Japan's OHISAMA Project Beams Solar Power from Space!
In a groundbreaking endeavor Japan is launching celestial energy with its OHISAMA project named after the Japanese word for sun This initiative aims to capture solar energy in space and transmit it wirelessly to Earth marking a significant stride in renewable energy technology The concept of space-based solar power SBSP was first proposed in by Peter Glaser The OHISAMA project involves a -kilogram satellite equipped with a -square-meter photovoltaic panel This satellite orbiting at an altitude of kilometers is designed to generate approximately kilowatt of power enough to run a small household appliance for an hour nbsp Microwaves The Invisible Power BridgeThe transmission of energy from space to Earth is facilitated by microwaves a method chosen for its ability to penetrate clouds and deliver power regardless of weather conditions This technology involves converting the stored solar energy into microwaves which are then beamed down to a ground-based receiver known as
