Wind turbines designed to be installed on rooftops are generating a lot interest lately. These compact turbines can be located on top of buildings, or attached to other parts of large structures like bridges. In turns out, though, that installing wind turbine in a city environment is a bit of an art.
The other challenge is to make these turbines noise-free and visually unobtrusive. So how power do these turbines produce? The Aerotecture FAQ says: “The estimated rated output of the 510V is 1kW in 30 mph winds; the estimated rating for the 520H is 1.8kW.”
As for the price:
The 510V Aeroturbine has an estimated cost of $15,000; the 520H Aeroturbine has an estimated cost of $21,000. This price includes the full system: rotors, cages, all the custom mounting structures, and electronic equipment (batteries are optional and sold separately). The cost of Aeroturbines will dramatically decrease with the advent of mass production.
