The Swift wind turbine has a blade/ring diameter of 7 feet; has a rated power output of 1.5 k and can generate up to 2000 kWh of electricity annually; at all wind speeds in generates less than 35 decibels of noise. In the product literature it is claimed that the Swift wind turbine, “has been designed to be environmentally sustainable. The product produces more energy in its lifetime than is incorporated in the material and prcess used to manufacture it — it is therefore ‘harm neutral’.” The Swift has 5 year warrantee and is designed for 20 years of use.
In terms of cost, Swift says that the estimated cost to install one its wind turbines is somewhere between $10,000-12,000; and that when current national incentive programs, current electricity costs, and assuming average wind speeds, the Swift can pay for itself in about 3 years.
The first commercial customer installation of a Swift wind turbine just took place at the Frauenthal Center for the Performing Arts, in Muskegon, Michigan.
