Japanese firm wants to transform the Moon into a giant solar power plant - 1 views

  • The Shimizu Corporation, a Japanese construction firm, has recently proposed a plan to harness solar energy on a larger scale than almost any previously proposed concept. Their ambitious plan involves building a belt of solar cells around the Moon’s 6,800-mile (11,000-kilometer) equator, converting the electricity to powerful microwaves and lasers to be beamed at Earth, and finally converting the beams back to electricity at terrestrial power stations. The Luna Ring concept, the company says, could meet the entire world's energy needs.

  • The 1GW station would involve four square kilometres of solar panels. It’s estimated to be about 2,000bn yen ($21bn) and 30 years away, and it would have to become much, much cheaper to get out there:
