STUDY: Roofs with White Surfaces 43 Degrees Cooler than Asphalt
A New York City roof covered in a white synthetic membrane was on average 43 degrees F cooler than surrounding black tar and asphalt roofsduring times of peak heat last summer, according to a study by scientists from Columbia University and NASA. On the hottest day of the summer — July 22, 2011, when the [...]
Capturing Solar Energy from Asphalt Roads
Scientists at the University of Rhode Island (URI) are developing ways to convert the solar heat generated by asphalt roadways into usable energy. The researchers say asphalt can reach temperatures of 140 degrees ormore in the summer. The URI team has designed four different methods to use this abundant resource. 1. Wrap photovoltaic cells around the [...]
PV in Asphalt = Solar Highways Are Coming
Scott Brusaw, an electrical engineer based in Sagle, Idaho, believes that addingsolar panels on rooftops will only be able to generate up to 2 percentof the total electricity demands in the UK. Brusaw further opines thatinstalling PV cells on highways is the way forward for renewable energy. The inventor plans to create 3.7m square panels [...]
