The most efficient form of renewable energy may be right underneath us. Researchers at Worchester Polytechnic Institute (WPI) in Massachusetts announced today that they have discovered a method to use road surfaces for solar collection.

The key is using the plentiful heat absorbed by asphalt pavement. By experimenting with different asphalt compositions, the team discovered that heat absorption in pavement can be significantly increased with the addition of highly conductive aggregates such as quartzite. Heat exchangers could be placed a few centimeters under the pavement to collect and use solar energy.
