Experimental sunlight-collection system in Japan produces 50 kilowatts of electricity
An array of shiny clover-shaped objects on an open field in Mitaka, suburban Tokyo is a sunlight-collection system developed by Japanese precision instrument maker Mitaka Kohki. The experiment in clean energy is being carried out in collaboration with the Mitaka city government. Each “clover” consists of four concave mirrors each 50 centimeters in diameter that reflects sunlight toward a 10-meter tower. The temperature at the light collector can reach up to 1,500 degrees, enough to produce 50 kilowatts of electricity.
