Home Wind Catchers Mount Airy NC

The 30-foot-tall Windspire� system can produce 1,800 kilowatt-hours of power a year in Mount Airy. When most homeowners think of residential wind turbines, they usually envision propeller-type systems. But two companies are offering unique wind turbines that are easy to install and are ideal for urban as well as suburban and rural residential installations.

When most homeowners think of residential wind turbines, they usually envision propeller-type systems. But two companies are offering unique wind turbines that are easy to install and are ideal for urban as well as suburban and rural residential installations.

The Savonious wind turbine, part of the Helix Wind line from San Diego-based New Earth, uses long helical blade scoops, made from aluminum, to catch wind from all directions and force it through a turbine. The turbine generator connects directly to the home, providing power as electricity is generated. When the wind is not blowing, the home draws power from the energy grid. And if the wind turbine produces more power than the home uses, excess energy can be sent to the grid (depending on the local utility), spinning the home's electric meter backwards.

The Savonious, which is available as a 1-, 2- or 4-kilowatt system, offers a number of benefits to homeowners. Because of its design, it can sit on a tower of just 15 to 35 feet (depending on obstructions), so it can meet typical zoning height requirements, which usually limit structures higher than 35 feet. It generates power in wind speeds as low as 3.5 miles per hour, runs quieter than a typical wind turbine and won’t harm birds or bats. It also can be roof-mounted. Prices start at about $6,500. For more information: www.helixwind.com or 619-501-3932.

The Windspire system, from Reno, Nev.-based Mariah Power, also features a vertical profile, standing 30 feet tall with a two-foot radius. Once installed, which takes only a few hours, the three rotor blades spin at just two to three times the speed of the wind, resulting in quiet operation. Made from corrosion-protected steel and aircraft-grade aluminum, Windspire is designed to operate for 20 years or more.

The 1.2-kilowatt unit can provide about 1,800 kilowatt-hours of power a year with an average wind speed of 11 miles per hour. It can be arrayed with additional units to provide more power, and comes with an internal wireless modem that transmits power-production information to your computer, so you can check its status at any time. The Windspire is priced at $3,995.
