... Idaho couple are thinking up a way to pave the country's roadways with solar cells, rather than asphalt or concrete. The so-called Solar Roadways are an edgy idea that the entrepreneurs said could replace much of the need for traditional sources of generating electricity in the U.S., including coal-fired power plants.
And they aren't the only ones who see the potential for roadways to become alternative energy sources.
Volvo is working with the Swedish Transport Association to turn a stretch of roadway in the city of Gothenburg into a rolling battery charger that would be used by specially equipped electric buses for recharging. The concept could someday help eliminate the "range anxiety" that electric vehicle owners suffer due to the limited capacity of today's batteries.
