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.
Often, when you think of solar power, you probably think about utility scale solar plants or solar power generated on a home or building. But have you heard about community solar, or what may be referred to as a solar garden? Like a community garden, solar gardens are popping up as an alternative to provide green energy to people and businesses who can’t (or won’t) generate solar power on site.
Announcements from LightFair this week lit up the news world. Lighting Science Group introduced cheap 40-watt and 60-watt replacement Definity LEDs, while Philips unveiled a brighter, more expensive 60-watt replacement EnduraLED. Not content with sitting the sidelines, Osram Sylvania today announced a bright 60-watt replacement LED that outputs 810 lumens.
