Japan plans massive solar power station to orbit earth



's greentech and then there's Martian greentech. A group of Japanese companies unveiled plans to build a 1-gigawatt solar power collector in space, according to Earth2Tech. The system would beam the power back to Earth using radio waves. This sort of system has been discussed in the past, but deemed too pie-in-the-sky. I mean, power stations in space? That's science fiction, right.

Apparently, not any longer. The consortium of dozens of Japanese companies will be led by the Japan Aerospace Exploration Agency, says Bloomberg. They plan to spend $21 billion on R&D over four years before hitting launch dates for the first stage of the project in 2015. The target completion date is 2030 or beyond. To put this in perspective, 1 gigawatt of power would be enough to power up to 750,000 U.S. homes for a year at current consumption rates.
