Shimizu Corporation, a Japanese construction company, presents proposals for six awe-inspiring megaprojects.
Luna Ring's 11,000-kilometer (6,800-mile) "solar belt" spans the Moon's equator.
Electricity collected by the Luna Ring's enormous "solar belt" is relayed to power conversion facilities located on the near side of the Moon. There, the electricity is converted into powerful microwaves and lasers, which are beamed at Earth. Terrestrial power stations receive the energy beams and convert them back to electricity.
Other proposals include giant floating cities in the sun-drenched equatorial Pacific, mega-city pyramids to house a million people, a low-Earth orbit space hotel, modular lunar bases, an underground network of "community facilities such as grocery stores, exhibition halls and public bathhouses," and a network of lakes and aqueducts in the desert.
