Tapping the hot asphalt jungle for energy

Now this is a neat idea. But don't think of it as a way to generate power. I figure we should look at it as ways to heat buildings. (Like the steam pipes that dominate the subsurface in New York.) If the buildings use less electricity or nat gas to heat their water or rooms, then then need less energy from the grid.A handful of Massachusetts researchers on Monday published a paper detailing a technique for using water-carrying pipes to convert the built-up heat in asphalt roads into usable energy.
