vertical axis wind turbine
South Carolina-based Firefly Power is one of 20 other social- or environmentally-inclined companies presenting at the i2i Awards program in conjunction with SXSW Eco in Austin through Friday, October 5, 2012. The company makes lightweight small wind turbines out of carbon-fiber blades in the vertical axis form. The residential unit is rated at 1.8 kW, weighs less than 60 pounds, cuts in at 10 mph winds, and is expected to sell for about $7,000, according to Firefly Power.
The small wind market is doing well these days with lots of new companies popping up all the time. Since 2007, Urban Green Energy, one of these newish companies, has been expanding and growing — their vertical axis wind turbine (VAWT) has been installed in 48 countries. One of their most recent installations was broadcast to the world last month on ABC’s Extreme Makeover: Home Edition (pictured).
A mixed-use project in Chicago has been getting a lot of attention for its green elements. Most noticeable, perhaps, is the beveled corner that holds 12 vertical-axis wind turbines (VAWT) by Helix Wind. The turbines are stacked in two columns on the building’s southwest corner and were included in the HOK designed-facade to cover all exterior lighting costs.
This is the Helenowski Residence, a gut-rehab in Chicago that achieved the highest LEED for Homes point total ever with 119 points, according to LEED for Homes provider Alliance for Environmental Sustainability. The 3,300 square-foot renovation achieved an impressive HERS rating of 13 and is net-zero energy with the help of rooftop solar power and a vertical axis wind turbine.
Urban Green Energy just announced the launch of “eddy,” a new small wind vertical axis wind turbine for home or office applications. The sleek wind turbine, according to the company, is “whisper quiet,” starts turning in 8 mile per hour winds, and has a maximum safe wind speed of more than 120 miles per hour.
Adobe’s installation of 20 small wind turbines on the sixth floor of their headquarters building made big news recently. But this is even bigger. Quinnipiac University in Connecticut is putting the finishing touches on a micro wind turbine cluster on its new green campus in York Hill. The “wind garden” is made with 25 vertical-axis turbines from Mariah Power and estimated to generate about 32,626 kWh annually.
