The Future in a Tiny Sphere: A Conversation with Yoshinobu Tsujikawa
February 5, 2007 10:45 AM
Japan leads the world in solar power technology. Japan not only produces half the total solar cells made in the world, it also exports 30% of these cells, with expected demand for 20% increases per year. The Japanese government pushes renewable energy policies that have resulted in the installation of more than 100,000 residential solar power systems by 2004, as well as a projection of 5 GW of solar generation capacity by 2010. Japan even plans to launch a solar satellite by 2040, which will deliver energy to the earth via low-intensity microwaves. The satellite will absorb the sun’s energy 24 hours a day, unobstructed by clouds, and generate one million kilowatts per second – equal to the output of a nuclear power plant.
