NEW ENERGY COULD RISE IN SOLAR BALLOONS
Could Solar Energy Be Generated with Balloons?
Greg Watry, January 6, 2016 (R&D Magazine)
“…[U.S.] utility-scale solar project developers have negotiated sales agreements to utilities at prices averaging 5 cents/kWh…[and] installed project costs have dropped more than 50% since 2009…[But solar balloons could eliminate] the whims of the weather…[I]nstead of waiting for sunlight to reach solar panels on the ground, balloons [could] capture solar energy up in the air, where space is not restricted, where yields would be multiplied and clouds would never interrupt production…[The solar ]energy source is five times more abundant than on the ground…[E]xcess solar energy captured by the balloon would be sent into a fuel cell, which converts the current into hydrogen through water electrolysis to keep the balloon floating. At night, the fuel cell recovers the hydrogen, which mixes with oxygen and produces water and an electric current…[Advocates say the concept] has the potential to make solar energy more sustainable and faster to deploy at large scale…” click here for more
