Pyron Solar Electric Generator

Pyron Solar Inc.’s (San Diego, CA) new Pyron Solar Electric Generator, runs at less than $3 per Watt with 1/4 to 1/20 the size of other systems. Pyron’s system works by concentrating direct sunlight 400X into its photovoltaic cells. Projections by Pyron estimate possible costs for large power plants at $1.24 per Watt and enough efficiency to power the entire US with a 50 square mile plot of land in the desert southwest.

A similar idea, at a larger scale, is being researched by Materialab (at RPI) as a curtain wall system with embedded Fresnel lenses that track and concentrate sunlight into PV cells. [article]
