Solar Power from a Balloon


Cool Earth Solar has one of those radical green-tech ideas that may actually make a real commercial impact.

They have developed a breakthrough solar technology that can ultimately produce enough clean energy to address the global energy crisis. This patented concentrated photovoltaic (CPV) technology dramatically reduces the cost and time to develop solar power plants capable of generating massive amounts of clean energy at prices competitive with fossil fuels.

Each 8-foot-diameter balloon concentrator is made of plastic film—the same kind of plastic film used to bag potato chips, pretzels, and so on—with a transparent upper hemisphere and a reflective lower hemisphere.
