The Swift Wind Turbine is a building-mountable unit that developers say provides a quiet, cost-effective renewable energy source for domestic, community, and industrial use.
The Swift Wind Turbine is said to fit well into urban and suburban areas because it operates quietly, at less than 35 dB says its developer.
Each Swift, from Cascade Renewable Energy Solutions, Grand Rapids, Mich., can provide about 2,000 kWh/yr in areas with above average or favorable winds (class 3 or higher), which equates to about 20% of the annual energy usage of a typical home. The turbine can mount to a single pole or attached to a house. The table tells of a few more specs.
