Luna Ring – Installing Solar Panels On The Moon And Beaming Generated Electricity To Earth. [Video]

Solar panels on the moon beaming electricity to Earth.

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]


Sunrun’s Advertisement: Going Solar To Save $’s First And Then Maybe The Environment

Sometimes green is a byproduct of saving money and that is what’s so great about Sunrun’s ad. Created by Heat, a San Francisco based ad agency, the advertisement is one of three that all hit the same spot with saving money as the primary motivation for going solar.

Sunrun’s solar lease model is similar to SolarCity’s. Basically, they’ll install solar panels on your property at no charge and you pay them instead of your utility for the electricity you consume. Sunrun’s ads are important because they will expand the market by encouraging homeowners who may be motivated by a different kind of green to switch to solar.

Jubbling’s take: we don’t care how you get to solar – just get there if you can. [FastCo.Exist]
