imo it would much smarter to try to extract heat power from roads rather than solar power. I always thought that in warm countries they should install piping under the roads with water that would get heated and brought to boiling thus generating electric power. Here is idea, instead of building stupidly expensive road that will most likely generate little power - just provide 75% grants to all that want to install solar panels, wind turbines or solar water heaters at their property. Problem solved.
