We have miles and miles of roads. Imagine if something could be done to ensure they remain pothole-free, crack free and heat free all year round. With specially designed solar panels, it is possible to turn a dark black road into a generator of electricity. This novel concept – the next big thing – is already been experimented upon and the results are fascinating. Not only will that make our world look like a set from ‘Tron’ but also help in protecting the environment by generating clean energy through solar roadways.
