Other Source of Energy

Inhabitat has a post on a particularly unlikely plan for space based solar power - Japanese Corporation Plans to Turn the Moon Into a Massive Solar Power Plant.

Man hasn’t been back to the moon since 1972, but that hasn’t stopped a team of Japanese engineers from developing a plan to turn our celestial neighbor into a massive solar power plant. The disaster at the Fukushima nuclear power station has made Japan think more seriously about alternative energy, and as a result Shimizu Corporation‘s crazy plan has been gaining traction. The plan calls for a massive 12 mile-wide, 6,800 mile long “Luna Ring” of solar panels to be constructed on the moon’s surface. The solar belt would then harness solar power directly from the sun and then beam it straight to Earth via microwaves and lasers.

Shimizu Corporation’s plan would see 13,000 terawatts of continuous energy sent to receiving stations around the Earth, where it will be then distributed to the planet’s population. With NASA’s plans to return the moon currently on hold, Shimizu is planning on building the massive lunar construction project with robots. In fact, humans will barely be involved and will only be present in an overseeing capacity.

CleanTechnica has an article on a round of funding from the US DOE for tidal and wave power research - US Taps Into 1400 Terawatt Hours Of Clean Ocean Power.

As the US offshore wind power industry slowly (very slowly) cranks up to speed, let’s not forget that US coastal waters also represent a huge, as-yet-untapped energy resource in the form of waves, tides and currents. The Department of Energy estimates the total could come up to 1400 terawatt hours of electricity per year, enough to power millions of homes. The problem is getting the private sector to take the plunge into uncharted technological waters, and to that end DOE has just announced a new round of $16 million funding, including public-private partnerships, to help kick things into gear.

The money will go to 17 projects that cover efficiency improvements in wave and tidal generators as well as data collection and environmental surveys.
