Solar power in space

Of course there has been use of solar panels in space on shuttles for decades but now there is talk.

There is talk of satellites that would electromagnetically beam gigawatts of solar energy back to ground-based receivers, where it would then be converted to electricity and transferred to power grids. And because in high Earth orbit, satellites are unaffected by the earth's shadow virtually 365 days a year, the floating power plants could provide round-the-clock clean, renewable electricity.^[1]
