This is Julie and Scott Brusaw, creators of Solar Roadways. Solar Roadways is a modular paving system of solar panels that can withstand the heaviest of trucks (250,000 pounds). These Solar Road Panels can be installed on roads, parking lots, driveways, sidewalks, bike paths, playgrounds... literally any surface under the sun. They pay for themselves primarily through the generation of electricity, which can power homes and businesses connected via driveways and parking lots.
I have no clue about you, but I bet that sustainable energy is the way to go. This is because of the benefits experienced in the use of this energy that is freely available. Majority of people see waste and dirt when they come across cow dung. But for me when I see cow dung I think of fire that never runs out.
