25. Self-Cleaning Streets
Such a simple idea that can save a huge hassle. Instead of those hulking street cleaning machines that produce tons of pollution into the air, this street is hooked up to a water source that rinses the road for safe traveling. This isn’t the only upgrade they have in the works, either.
They’re also working on roads that use solar for the lights and have a heating element to thaw the snow and ice in the winter. They’re calling them “smart roads,” and the design is one step closer to dust and pollution-free environment. They spent years cleaning the roads back in 2013, and this idea was born from that arduous task.
