Here’s an interesting idea, use the wind generated from cars on highways to power turbines, Joe writes -
The highway system that dissects Phoenix is expansive. While connecting 515 square miles of the Sonoran desert to support our sprawling culture, the valley freeways divide communities. My catalyst proposes to retroactively collect royalties on the land taken from social interaction. The design is a retrofitting replacement of the horizontal steel tube that currently holds freeway signage. The replacement will house two horizontal axis wind turbines (Quiet Revolution designs) that will be powered by the turbulence created from the passing cars.
