For a few years, engineers think how to get a such much power of heat and light of sun directly from space to earth. Many concept and design have assigned but none of them are succesful. Now, with the advanced Photovoltaic cell, it will be build. Flower Solar Power space setup is nicknamed SPS-ALPHA. As spaceborne advanced energy-harvesting schemes go, this one seems faintly possible — an array of curved mirrors directing sunlight toward solar cells, their energy production microwaved down to earth. It’s so realistic, actually, that NASA is providing funding for a proof-of-concept study.

NASA is seriously will funds for project of energy that beam down to earth from above. It will be make a great efficient, because the power that beam down will be more much than the power that collect from photovoltaic cell on the land of earth. A former NASA engineer named John Mankins, now with a company called Artemis Innovation Management Solutions, detailed his plans at a NASA innovation conference recently. The concept is called called Solar Power Satellite via Arbitralily Large Phased Array (SPS-ALPHA), and it would harvest solar energy from a perch in high Earth orbit.
Moreover, it would consist of a modular array of movable thin-film mirrors, which could be taken into space using current cargo ships and assembled piece by piece. This would be less expensive than building a gigantic array and launching it. These curved mirrors would redirect sunlight toward an internal collection of advanced photovoltaic panels, and the solar energy would be converted into microwaves. Then the Earth-facing portion, or the bottom of the margarita glass in the image at top, would transmit low-frequency, low-intensity technology waves toward Earth. At the receiving end, power plants would convert the microwave energy into electricity, adding it to the power grid.
