Wind powered light uses the moving air from cars zipping by on the highway to generate energy that can be used to power roadside lighting.
It’s a controversial idea–could wind from passing cars actually provide enough power for lighting? Well, theoretically speaking you light up an entire city by harvesting renewable energy contained in the air turbulence generated by passing traffic.
But one that has the potential to save lots of cash in already wind-heavy regions. The idea has been proven to work many times over, including at the recent COP15 climate change conference.
