The solar discs that could beam power from space – BBC News
Space-based power stations are turning from an idle dream into a serious engineering prospect, as scientists hope they can take renewable energy into orbit.
The possibilities dont end there. While we are currently reliant on materials from Earth to build power stations, scientists are also considering using resources from space for manufacturing, such as materials found on the Moon.
But one of the major challenges ahead will be getting the power transmitted back to Earth. The plan is to convert electricity from the solar cells into energy waves and use electromagnetic fields to transfer them down to an antenna on the Earths surface. The antenna would…
