Turbine Placements

Pruned has an intriguing post about a proposal by Mark Oberholzer to install Darrieus wind turbines into motorway barriers. The idea is that the wind from passing cars will drive the turbines and generate electricity. I can’t help feeling that you would have to choose the motorway carefully. Any traffic jams, and it’s not only the cars that would come to a stop, but also the possibility of power generation.
