Hmmm, interesting Q in parliament yesterday: Solar Power: Satellites
Laura Sandys: To ask the Secretary of State for Energy and Climate Change whether the Government has (a) commissioned or (b) evaluated any research into the practicalities of transmitting solar energy by satellite from space to Earth. 
Gregory Barker: We are not aware of any such research undertaken by the Government. The 2011 Budget includes a £10 million provision for the UK Space Agency to support the development of space technology in the UK through a competition process which could include technologies for space-based solar power generation and supply to ground.
