Roads and parking lots as solar collectors? Is that the newest revolutionary innovation since the term “alternative energy”? Capturing solar energy from pavements has been perfected for years now.
Researchers at the Worcester Polytechnic Institute will unveil Tuesday, August 19, 2008 the findings of a research project on the concept of using the heat absorbed by pavements. Rajib Mallick, associate professor of civil and environmental engineering, who was the team leader will hail the achievement as “revolutionary”.
By using the heat from asphalt, the researchers have developed a solar collector that could turn roads and parking lots into invisible and cheap sources of electricity and hot water. (Full Story at ecoworldly)
I just have some doubts about this whole idea. Seems like it cld be expensive, failure prone, and with little returns (in terms of energy). Maybe I'm just a naysayer. Anyone else have thoughts on this.
