Technology is not limited to just cars or gadgets. Given enough thought, it can be implemented to anything in the world, for example roads.
Roads play an equally important role in terms of safety. Say during winter, ice causes road accidents and heavy machinery is required to clear snow. Lane markings are another important feature that save lives.
What if such things can be taken care of without harming the environment? A startup is doing exactly that with solar panels that can be used to make roads. The panels are heavy enough to carry vehicles and can pay for themselves.
The solar roads can clear snow, replacing heavy machinery that pollute, mark lanes, and can produce enough energy as a small powerplant.
