Get out of a car in a parking lot on a hot summer day and you will really feel the heat. A new approach to capturing this heat and turning it into power is showing promise.PopSci.com reports:
"Rajib Mallick, an engineer at Worcester Polytechnic Institute who studies the effect of solar radiation on cities..... has devised a way to harness heat from baking blacktop and turn it into electricity. His system pumps water -- an excellent heat conductor -- through a network of copper pipes embedded in asphalt. As the water circulates, it pulls heat from the scorching surface and produces steam to drive a turbine that cranks out electricity. Mallick is partnering with the University of Massachusetts Dartmouth and the optics firm Novotech to install a full-scale system beneath a 10,000-square-foot parking lot near Worcester, Massachusetts.
