We left the cool air-conditioned building and travelled to Brooklyn to visit Urban Green Energy's eddy vertical axis wind turbine at a construction site. Taking the A and thereafter the F, we arrived at the site where a green entrepreneur has erected a wind turbine in his ultra-green building. The complex’ features are innovative: recycled materials make up 70% of the building, super-insulation will keep its inhabitants toasty and it will be fully powered by wind and solar generators.
