Great find. I hope it works out. If they could get Nanosolar on board with this they can make it even cheaper and easier to roll out. In addition,
the roadbeds would be more durable.
In a first step toward turning highways into energy-generating solar panels, the Sagle, Idaho-based startup Solar Roadways has recently received a $100,000 grant from the US Department of Transportation (DOT). The company will use the money to build a prototype of its Solar Road Panel, made from solar cells and glass, that is meant to replace petroleum-based asphalt on roads and in parking lots.
The 12- x 12-foot panels, which each cost $6,900, are designed to be embedded into roads. When shined upon, each panel generates an estimated 7.6 kilowatt hours of power each day. If this electricity could be pumped into the grid, the company predicts that a four-lane, one-mile stretch of road with panels could generate enough power for 500 homes.
Although it would be expensive, covering the entire US interstate highway system with the panels could theoretically fulfill the country's total energy needs. The company estimates that this would take 5 billion panels, but could "produce three times more power than we've ever used as a nation - almost enough to power the entire world."
Wow. What a dream! I really look forward to seeing how this technology performs and its impacts on our current energy paradigm. I have to say
that in recent months the advances being made in the realm of alternative energy has been huge. I really feel like we have come to a tipping point
where these 'alternatives' are going to become main-stream.
