I’ve been wondering why we don’t have these on top of our street lights. I imagine a street light with a Darrieus vawt on the pole under the light and a small solar panel on top.
There is a roadside vertical turbine concept which seems promising. It uses lampposts as a mounting point, reducing materials needed, reusing existing cables in the lamp, and scavenges energy from trucks thundering by. And since it's in a developed area, you don't affect existing views.
