Plastic parts maker Cascade Engineering is bringing a small rooftop wind turbine called the SWIFT to North America. The company says the SWIFT is significantly quieter than traditional small wind turbines — less than 35 decibels, compared with 40 to 50 decibels for competing products. The tiny turbine is already available in the UK, Belgium, New Zealand and the Netherlands through its Scottish designer, Renewable Devices. Cascade has licensed the technology to bring it to the U.S. (source: earth2tech.com)
