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.
Southwest Windpower, maker of the Skystream 3.7, unveiled a new version of the popular turbine at CES 2011 called Skystream 600. The turbine features an improved design with larger blades, enhanced software, and an improved integrated inverter. And, according to a press release, Skystream 600 will be the “first fully smart grid-enabled wind turbine” on the market when available in April 2011.
