If you've ever stood by a highway with a couple thousand cars whizzing by at 60+ mph you can attest to the amount of wind that the traffic pushes past you.
What if there was a way to capture this "traffic wind" and turn it into usable power?
The idea here places vertical axis wind turbines inside specially constructed highway dividers. The opposing traffic pushes the air past the turbines, which spin a generator, turning the wind into electricity.
