It’s called the Luna Ring and it’s one of Shimizu Corporation’s sustainable ideas for powering future Earth. It’s not a new idea but the Luna Rings video is making the rounds again. Here are some tech specs on the Luna Ring:
“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 side of the Moon that’s always facing the Sun, and beam it down to Earth from the side that’s in shadow. 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. The concept also calls for remotely-controlled robots to undertake tasks such as excavating the surroundings, leveling the ground and laying out solar panel-studded concrete. Embedded cables could transfer the collected solar energy and send it to transmission stations.
Power could be beamed to the Earth through microwave power transmission antennas, about 20 m (65 ft) in diameter, and high density lasers, both guided by radio beacons. Microwave power receiving rectennas on Earth, located offshore or in areas with little cloud cover, could convert the received microwave power into DC electricity.”
So besides everything, what could go wrong with Luna Ring? This makes my idea to dam the mouth of Puget Sound, drain it, so I can catch all of the salmon seem sane. I think I’ll put my idea on a 30 year plan. [Gizmag]
