Nov. 17, 2012 One of the most interesting talks at the Festival of Faiths was about Solar Roadways (http://www.solarroadways.com/).  The basic idea: replace asphalt roads, parking lots, and driveways with solar panels built to withstand the weight and wear of traffic.  These roads would be well marked with LEDs (better than our present painted lines), heated to melt ice and snow in winter, and used to collect energy to be used by our homes and businesses.  Electric cars could be charged while they drive on the roadway. This renewable energy replaces the need for the current fossil fuels used for the generation of electricity.
