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.
Over the weekend, Hoffman Construction lifted four Southwest Windpower turbines into place on top of a new building, Twelve West. Located at Southwest 12th Avenue and Washington Street, Twelve West includes a mixture of office and apartment spaces and was designed by Zimmer Gunsul Frasca Architects to achieve LEED Platinum certification. ZGF included the turbines in early renderings, and developer Gerding Edlen, probably the foremost green developer on the West Coast, determined to give the turbines serious chance.
The Architectural Review recently mentioned an interesting facade installation on an office building in Utrecht, Netherlands. Designed by Cepezed, in collaboration with Ned Kahn Studios, the facade is made with about 3,250 square feet of stainless steel mesh. The mesh grid holds transparent plastic disks, or squares rather, that vibrate and move to the wind. The effect is an artistic facade that produces a mezmorizing array of shade and light, together with exterior wave patterns that captivate.
Last week, we mentioned that the small wind market is growing like crazy, and if things go as planned, there could be another turbine company to watch. The Honeywell Wind Turbine from EarthTronics, according to Martin LaMonica of CNET, will be sold in participating Ace Hardware Stores starting this October. EarthTronics claims the turbine can generate power at wind speeds as low as 2 mph. With Class 4 winds, the turbine can generate about 2,000 kWh per year, which is roughly 15-20% of an average home's electricity needs.
The American Wind Energy Association (AWEA) just released a new report, the AWEA Small Wind Turbine Global Market Study, detailing a sizable advance in the small wind turbine market in the United States. Small wind turbines, you may know, are those with a capacity of 100 kW or less. And the U.S. market for this niche grew 78% in 2008, with a total of 17.3 (MW) of new installed capacity. The report indicates that the growth is due, in large part, to private equity investment in the sector, as well as economies of scale, rising electricity prices, and heightened public interest.
This is the first LEED Platinum home in Vermont, although perhaps more importantly, it's a documented and legitimate zero net energy home. From January 2008 to January 2009, the 2,800 square-foot, single-family residence exported 16 kWh of electricity to the grid. Over the same time period, a Bergey 10 kW net-metered turbine generated 6,286 kWh of on-site, green energy. Designed by Pill - Maharam Architects, the handsome farmhouse was built for a family of four and features a number of green elements:
On Earth Day, the National Children's Museum unveiled plans for a new building designed by Pelli Clarke Pelli Architects. If all goes as planned, the building will obtain LEED certification and open in 2013. The design reflects the Museum's mission to inspire children to care about and improve the world. NCM's new, 150,000 square-foot facility will be built at National Harbor with some of the following green features:
This conceptual proposal for a residence with combination solar panel and wind turbine offers the best of both worlds, with a dose of stage-like performance. Shaped to look like a rock, the dwelling stores water in its outer shell as an insulator to conserve energy. Furthermore, the transforming device embodies a playful spirit with its daisy-like shape that seems more like a toy rather than a high tech piece of equipment.
