Scottish company, Renewable Devices designs and distributes what they say is “the quietest rooftop wind turbine currently available.” The small footprint, Swift Wind Turbine, is designed for both commercial and residential use.
The 7′ diameter turbine produces 1.5kW @ 14 m/s, or roughly 2,000 kWh per year (roughly 20% of average home use) and requires about 2′ of roof clearance.
Commercial installations can consist of multiple units. Wind energy is dispersed along the blades to outer ring which acts as a ‘diffuser’ creating less noise. U.S. based, Cascade Engineering, will manufacture the turbines blades and assemble all the units sold in the U.S.
Installed, this turbine will run you $10,000 to $12,000.

You may wake up on the wrong side of the bed, but that doesn’t mean you should start your day off on the wrong foot. The citrus pros at Sunkist recently debuted a new line of all-natural smoothies and juices that will help you make the most of your mornings. Available in eight different flavors, they’re made with good quality fruits, like Alphonso mangos, Valencia oranges and Marion blackberries from the Pacific Northwest, all selected from small, regional farmers.
The juices are loaded with healthy antioxidants and nutrients, and they’re free of additives and preservatives, making them a healthy alternative to the many sugar- and preservative-filled fruit juices lining grocery store shelves. I’ve tried two of the eight varieties: Glorious Greens, made with wheat grass, flax seed, spirulina and green tea; and Berry Cherry, a tasty blend of Oregon, Washington and California raspberries, Bing Cherries and strawberries. Available in the refrigerator sections at Whole Foods, Kroger, Fairway, Hannaford, and H·E·B.
