This startup company, RavenBrick, was profiled by the New York Times for its simple and smart window technology. It's a window like nothing else on the market. Using patented and patent pending technology, RavenWindow has a reflective film that's keyed to the outside temperature. When warm, the film reflects light to reduce solar heat gain. Conversely, when cool, the film becomes transparent to allow a comfortable amount of heat gain.
The American Wind Energy Association (AWEA) recently released its annual Global Market Study [PDF] of the small wind market, and I thought I'd share this information considering the intersect of green building and small wind. According to the study, the U.S. market for small wind turbines — those with a capacity of 100 kW of less — added 20.3 MW of new capacity on $82.4 million in sales in 2009.
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.
