Japan's space agency planning space-based solar power arrays !

We have seen are a few fairly solar installations, but JAXA, the Japanese Space Agency is to really too far with his latest project: a space-based solar cell, the carrier power back to Earth. The Agency is beginning tests on the microwave power transmission at 20 February, with an attempt to beam enough power over the 2.4-GHz band to power a household heating to 50 metres (164 feet). This is certainly not the kind of large-scale projects sci-fi power system, we were hoping, but not fret - if the tests are successful, JAXA's plan is ultimately a constellation of satellites suns, each beaming power to a 1, 8-mile wide angle receiving station that you produce 1 gigawatt of electricity and power 500000 homes.
