Use of Asphalt Paved Surfaces For Solar Heat 110

vg30e writes "It seems that a company in the Netherlands has found a way to use asphalt paved surfaces as solar heat collectors. Flexible tubes under the surface of the road collect heat from asphalt pavement using water as the working liquid. The heated water is stored underground for later use in defrosting the road, or heating buildings. With all the miles of highway in the continental US, this might be a viable way of collecting massive amounts of thermal energy."

The reason: truck drivers using GPS navigation devices are being directed to drive through the town despite the roads being too narrow for sidewalks, and causing numerous accidents. At the root of the problem lies the fact that the navigation maps used by trucks are the same as those used by passenger cars, which don't contain data on road width or no truck zones. Tele Atlas says they will release truck-appropriate databases at some point, but until then they advise local governments to make use of a technology dating back to the Romans: road signs."
