Illustration for article titled Solar Energy Available from the Asphalt?

It must be bass-ackwards Thursday or something because rather than slapping solar panels on the car, the solar-energy is coming from the road, in a way. The Dutch company Ooms Avenhorn Holding has managed to squeeze solar energy out of the asphalt.


The Road Energy System is a asphalt system with integrated tubes placed underneath. As the sun pounds down on the road, the tubes contain water that is heated and filtered. As an example, the current project plans to heat four office buildings with the radiated heat.

The obvious downside is the cost. The roads are reportedly four times more expensive to build than plain old asphalt, but on the other hand, stored heat under the roads could always help reduce icy roads during the winter months. [CNET]
