That could happen about five years from now, perhaps using a laser on the International Space Station to transmit solar power collected by its panels to Earth.

Such a grid is being tested at the army's model forward operating base (FOB) in Fort Irwin, California, along with prototypes of a mobile, hybrid power station that combines solar panels and wind turbines with a conventional generator.
