Sloan Valve Company, manufacturer of water-efficient plumbing products, including the AQUS greywater system, last summer installed two small wind turbines in Illinois from Aerotecture International. The Franklin Park headquarters building now has two 712V Aerotecture vertical-axis models. One is over the front entrance and another is over the employee entrance, while both are ballasted to the roof.
Adobe’s installation of 20 small wind turbines on the sixth floor of their headquarters building made big news recently. But this is even bigger. Quinnipiac University in Connecticut is putting the finishing touches on a micro wind turbine cluster on its new green campus in York Hill. The “wind garden” is made with 25 vertical-axis turbines from Mariah Power and estimated to generate about 32,626 kWh annually.
Kroon Hall, the new home of the Yale School of Forestry & Environmental Studies, has been awarded Platinum certification, according to the Office of Public Affairs of Yale University. Kroon Hall was designed to use 81% less water and 58% less energy than a comparable building, helping it receive a total of 59 LEED points. With the help of a massive and beautiful solar array, about 25% of this building's electricity should be generated on-site, too.
Most address numbers probably don't have back lights, but I suppose if you're going to light them, you might as well do it with solar power and LEDs. That's how it's done with these Solar LED Address Numbers from Think Geek. The numbers turn on automatically and can last up to 10 hours on a full charge. Each number runs about $16. My place is in dire need of a number swap, so I guess these are now at the top of the list. What do you think?
Not much has changed since our last update on the Honeywell Wind Turbine, except WindTronics released this video showing the gearless blade tip system at work. It’s spinning nicely, and the company claims it can start generating energy at winds speeds as low as 2 mph (and up to 42 mph). The $5,995, soon-to-be-launched small wind turbine can produce up to 2000 kWh/yr in class 3 winds and up to 2752 kWh/yr in class 4 winds.
A couple years ago, I watched with caution as Philippe Starck announced plans to design residential scale vertical axis wind turbines. Everyone loves the idea of small wind — especially VAWT designs — but practical issues can sometimes preclude actual energy generation with these things. Nonetheless, after two years of research, it seems the French designer has some actual products to speak about. Speaking to a crowd in Milan, Starck unveiled two Revolution Air turbine models to be made by Pramac.
