China plans to build enormous solar array in space — and it could collect more energy in a year than 'all the oil on Earth'
Chinese scientists plan to build an enormous, 0.6-mile-wide solar power station in space that will beam continuous energy back to Earth via microwaves. The project has been dubbed 'another Three Gorges Dam project above the Earth'. The Three Gorges Dam is the world's largest hydropower project. Based in China, it generates 100 billion kilowatt-hours of electricity each year. The US, EU, and Japan have also been investigating solar satellite array technology - Japan's JAXA is set to launch its proof-of-concept satellite this year.
