Southwest Windpower, maker of the small-wind turbine Skystream, just announced a refreshed Whisper line of turbines for battery-charging applications including off-grid residential homes. The Whisper 100 (7′ diameter) has the potential to generate up to 100 kWh per month at 12 mph; the Whisper 200 (9′ diameter) has the potential to generate up to 200 kWh per month at 12 mph; and the Whisper 500 (15′ diameter) has the potential to generate up to 538 kWh per month at 12 mph.
As the small wind industry grows, it’s becoming easier to buy certain models of turbines online and from big-box retailers. For example, Southwest Windpower offers the Skystream 3.7 through Home Depot and now offers the Whisper 100 through Lowe’s. Whisper 100 can produce up to 100 kWh a month in moderate to high winds, according to Southwest Windpower.
This is the donQi urban wind turbine, which is assembled in Rotterdam. It’s an interesting small wind product and the subject of a recent article in the September 2011 issue of Dwell. In the article, Second to None, Jane Szita describes a Passive House near Amsterdam by architect Pieter Weijnen. The home has some beautiful Japanese-style charred siding and a sleek-white, residential donQi.
