you are looking at what may be the future of renewable energy.

A company in California, Pyron Solar, is making the bold claim that its solar power system can compete head-to-head with conventional power plants. The system, developed with Boeing-Spectrolab, is very compact, and uses short-focal-length lenses to concentrate direct sunlight to photovoltaic cells. The company says these cells produce 800 times more electricity than conventional non-concentrating cells of the same size. Their first prototype, which is 23 feet in diameter and 16 inches high, produces an astonishing 6.5 KW of electricity, enough to power six homes.
