This is the Helix Wind Turbine, a small-wind, residential scale option that could cut your electricity bills in half, if installed and situated properly. This 2-kw grid-tie or off-grid system is designed to catch winds at lower speeds. And it won’t hurt the birds, either. According to the company’s website, the Helix System is inexpensive, reliable, and simple — it’s a good choice for low wind speed residential and commercial applications. The Savonius turbine based design catches wind from all directions creating smooth powerful torque to spin the electric generator. Perfect customers live in areas that have amenable small wind zoning and get about 10 mph of wind/cross-winds. Via EcoGeek.
Matt Allert took second place in the Cascadia Region GBC‘s Emerging Green Builders Natural Talent Design Competition this year with his idea, the Dwelling Dock [pdf]. The Dwelling Dock is premised on the idea that sustainability should begin with the most basic building block of our communities: the dwelling. It’s an attempt to fully integrate the infrastructure of the housing unit with the environment. Although purely in concept stage, the Dwelling Dock would be prefabricated, and would include all the accoutrements we’ve come to expect in green homes: pervious paving, recycled materials, living roof, water collection, and photovoltaic panels.
Allert’s goals for the Dwelling Dock project include some of the following: (1) collect rainwater for re-use, (2) produce energy on-site, (3) minimize site disturbance and preserve existing site resources, (4) use local materials, and (5) integrate sustainable design with recycled, low-VOC materials. And I’ve got to admit, I really like the design elements. Butterfly living roof. 3-level living. A healthy mixture of privacy and transparency. Would you live in one?
