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."

    So they're using a series of tubes to make renewable energy? Seems like you can do anything on the internets these days...

    Pipes and water just sound like a bad idea in general. Sounds like high maintenance costs, not necessarily suitable for all weather environments, high installation cost, specialized labour and more unions, ... it just sounds impractical.
    Right, certainly not as practical as your apparently low maintenance, all weather, low cost, monkey installed, made from unicorn horns electrical asphalt.

    I was having trouble following the process because I am unfamiliar with this "water" material you used in your example. Thank goodness you gave an analogy using "orange squash." Now the process is crystal clear because I am much more familiar with "orange squash" than water, as I'm sure is the case with most everyone reading this.
