Solar Roadways

[Straight from Slashdot] “Solar Roadways, a project to replace over 25,000 square miles of road in the US with solar panels you can drive on, just received $100,000 in funding from the Department of Transportation for the first 12ft-by-12ft prototype panel. Each panel consists of three layers: a base layer with data and power cables running through it, an electronics layer with an array of LEDs, solar collectors and capacitors, and finally the glass road surface. With data and power cables, the solar roadway has the potential to replace some of our aging infrastructure. With only 15% efficiency, 25,000 square miles of solar roadways could produce three times what the US uses annually in energy. The building costs are estimated to be competitive with traditional roads, and the solar roads would heat themselves in the winter to keep snow from accumulating.”

    Cool.
    Lots of new jobs in a new, green industry too…

    Call me skeptical.

    I don’t doubt they can texture the glass when it is installed, but I would still question its ability to maintain a suitable level of traction as the surface wears. Wouldn’t it tend to become… well…… glassy?

    I also tend to think deploying solar panels in other locations – more specifically targeted to sun exposures and sited within the power grid – would be more cost effective.

  1. No trackbacks yet.
