writes "We were just talking about glow-in-the-dark roads and how they were having issues already. Now there's a company called Solar Roadways that's looking to make glowing, solar, smart roads. Back in 2009 the Department of Transportation awarded Solar Roadways $100,000 to prototype road systems with embedded digital signage and dividing lines, all powered by the sun. As it turns out, the company's prototype performed well — so well that Solar Roadways is now looking to go big-time, and it's asking for your help to do so. At the heart of the Solar Roadways project sit a vast number of hexagonal tiles. The bottom of those tiles consist of solar panels and circuit boards, covered with a thick sheet of tempered glass. The panels contain LED lights, which can be configured to mark traffic lanes, send messages, or fulfill other functions. The panels also have heating elements to help melt snow and ice during colder months. Are these smart roads the future, or just another pipe dream?"
