Cascade Engineering today launched their SWIFT Wind Turbine for sale in the US and Canada. The SWIFT, which was originally designed by Scotland based Renewable Devices, is a unique small five bladed wind turbine that is designed to reduce noise. The five blades are surrounded by a “diffuser ring” that lowers the sound produced by the turbine to a measly 35 decibels.
The SWIFT design also helps to reduces vibration, which allows the wind power turbine to be mounted directly to a house, rather than to a free-standing pole or tower. The Swift also has two fins to turn it into the wind – it can turn 360 degrees to take advantage of any wind direction. The Swift generates about 1.5 kilowatts with a 14 mph wind; Cascade says that in typical use it will generate about 2,000 kilowatt hours over a year, which is about a quarter of the amount of electricity a typical household consumes in a year.
The Swift’s installed cost is about $10,000, but that’s before any state rebates and federal tax credits ($1,000 for residential systems and $4,000 for commercial buildings). Cascade says that the payback cost of the Swift Turbine can be as low as three years.
