Shimizu’s Luna Ring to beam solar energy from the Moon

A Japanese firm has come up with the idea of constructing an array of solar cells around the Moon’s equator to harvest solar energy and beam it back to Earth. The Shimizu Corporation proposes creating a “Luna Ring” using materials derived from lunar soil along its 11,000-km (6,800-mile) equator. The plan involves starting with an array that’s a few kilometers wide and eventually increasing that to around 400 km (250 miles).

The goal is to generate a continuous stream of power from the Moon’s lunar equator, which receives a steady amount of exposure to the Sun, and beam it down to Earth from the near side of the Moon. It’s an ambitious idea that calls for assembling machinery transported from Earth and using tele-operated robots to do the actual construction on the Moon’s surface, once it arrives.

The multi-phase project, to be spread out over a period of 30 years, envisions creating construction materials using a combination of strategies. Water, the firm claims, could be produced by reducing lunar soil with hydrogen imported from Earth. The company also proposes making lunar concrete by extracting cementing material, and utilizing solar-heat treatment processes to create bricks, ceramics, and glass fibers.
