I read this from Discovery Channel Magazine Feb 2010 (asia version I think):
“Imagine a future with no power plants and no electrical transmission lines, but plenty of cheap electricity delivered right to your door. Sound impossible? Not if we pave our roads with solar panels. The road would become both the source of electricity and the means of distributing it. This is the dream of Scott Brusaw, co-founder of Solar Roadway, a company based in the US state of Idoha. The dream drew a step closer to reality last August when the US Department of Transportation issued the company a USD100,000 contract to develop a prototype 13.4 square-metre panel. Brusaw hopes that similar panels will some day cover all 65,000 square kilometres of the nation’s roadways.”
