This month, AES Wind installed its first demonstration AES WindJet 5 turbine in Overland Park, Kansas. The twin-rotor turbine is rated at 5 kW and was designed to increase efficiency by up to 54% over existing designs. With a slow rotor speed, the turbine is quieter, more durable, and less likely to create problems with birds.
Earlier this week, Green Wavelength LLC, a bio-inspired clean energy startup, unveiled their 19-foot, prototype, small wind turbine to crowds at The Perfect Pitch 2009 entrepreneur conference. Called XBee, the turbine – unlike any that you’ve probably ever seen – was designed with inspiration from the movement of bumblebees, hummingbirds, and dragonflies.
One hundred years ago, in 1909, architect Daniel Burnham and Edward Bennett completed a document called the “Plan of Chicago,” which, to use the words of The New Yorker, “determined the shape of modern Chicago.” Now, in an effort to build upon the work of Burnham and plan for the next 100 years, Big. Bold. Visionary: Chicago Considers the Next Century presents the work of nearly three dozen architects and planners with a vision for the windy city.
