Electric Avenue: Solar Road Panels Offer Asphalt Alternative [View all]

http://www.spiegel.de/international/world/solar-road-panels-offer-asphalt-alternative-a-901792.html


This is how a road made of solar panels might appear. Since many LEDs are built into them, up-to-the-minute traffic information, such as areas where an accident has recently occured, could be displayed directly on the surface of the road.

A lot of thought is put into how much energy we use to drive from point A to B. But what if the road itself could generate energy? Julie and Scott Brusaw, a married couple from Sandpoint, Idaho, have taken on just such a concept, which they hope will make the auto transport of the future cleaner and safer.

The idea is as simple as it is ingenious. Wherever roads are laid, solar panels could go instead. They would generate electricity, which would in turn be fed into the grid. Thus, oil is conserved twice: Electric cars could be charged with the energy produced by the panels, and the panels would replace the use of asphalt, the production of which requires petroleum.

Moreover, Solar Roadways, as the Brusaws have dubbed their invention, are heated and equipped with integrated LED screens, which act not only as street markings, but can also show warnings directly on the road.

The Brusaws are aware that their vision cannot be realized in a day. They've decided to start small: with pedestrian and bicycle paths or large parking lots at supermarkets. As they see it, every square meter of asphalt that gets replaced with Solar Roadway is a small step on the path toward independence from fossil fuels. The giant leap would be to take on urban roads and highways on a global scale.
