I saw this light standard on interactive architecture a while back that integrates a helical wind turbine with a solar panel and thought while it is not the most beautiful light, that the idea of integrating alternative energy into urban landscape projects was intriguing. It could be a great design element.
Another interesting product is the QR5, but it is very expensive.
Has anyone seen other projects that have incorporated wind and/or solar energy?
Integrating pedestrian scaled wind turbines does seem like it would pose some safety issues that would need to be addressed. I am also curious how quiet the helical turbines are compared to the more convention horizontal axis turbines. The horizontal ones can be loud.
