Breaking the Ice

Summer is a time for pools, popsicles, and parching pavement. Fortunately engineers at the University of Rhode Island are researching methods to use this hot heat to melt ice off roadways in the winter, power street lamps and signs, and heat buildings. Because asphalt temperatures can reach up to 140 degrees harnessing the heat would be very practical. Engineers are looking at a variety of methods including placing photovoltaic cells on highways and water-filled pipes under the road that would be heated. These methods promise another method of alternative energy use, diminishing dependence on fossil fuels.
