Well here is a clever idea by Berlin designer Tobias Trübenbacher. It is a wind-powered streetlight -- one that also detects when people are nearby and emits an insect-friendly light spectrum. Lots of cities already rely (partially) on solar powered lights and signage. But that doesn't always work if the street doesn't get a lot of direct sunlight or if you happen to be in a darker city. So perhaps wind is the answer. I could imagine this working very well here in Toronto in the middle of the winter at the intersection of Bay and King. And if you remember my post from earlier in the week about a roadmap to net zero energy, it is pretty clear that both solar and wind electricity are going to need to become far more prominent in our cities.
