At the very least solar roadways might power electric cars. The inventor, Scott Brusaw, speculates that just converting 1.7% of the nation’s existing highway system could power the whole nation.
The heart of the solar roadway concept is the solar road panel. Each individual panel consists of three basic layers, the road surface layer, which is translucent and high-strength yet rough enough to provide traction. The surface layer is capable of handling today’s heaviest loads under the worst of conditions and protect the electronics layer beneath it.
