Air Breeze Off-Grid Wind Turbine Improves Upon Popular Air-X

Air Breeze by Southwest Windpower

If you’ve heard of the popular Skystream 3.7 by Southwest Windpower, then you’re probably familiar with their smaller wind turbine called Air-X.  Air-X was introduced in ~2001 and flew off shelves, selling over 100,000 units.  Building on the success of Air-X, Southwest Windpower recently released Air Breeze, its next iteration of the successful small wind generator.  I first noticed an ad for Air Breeze in Natural Home Magazine last September and have since seen news of it popping up everywhere.  Air Breeze was engineered to be quieter, more efficient, and more effective at lower wind speeds …

Off-Grid and Carbon Free in Samsø

Samso

A few months ago, I became interested in Samsø after reading Elizabeth Kolbert's column in The New Yorker entitled The Island in the Wind.  Then, just this week, I noticed a photo essay of Samsø in The Guardian with pictures from Nicky Bonne.  What's interesting about Samsø is that it's a producer of energy — the entire island produces more energy from renewables than it uses.  They sell the rest and have been doing so since 2003.

Putting Parking Lots to Good Use

Envision Solar Parking Garage

University of California, San Diego is in the process of installing Solar Trees by Envision Solar on the roofs of two of its parking garages.  The Solar Trees are designed to provide clean energy for the campus, shade for vehicle parking, and future infrastructure for electrical vehicles.  Each Solar Tree at UCSD will generate more than 17,000 hours of clean energy per year, which is enough to power more than four single-family homes.  In aggregate, with two parking garages topped with Solar Trees, you can imagine the power they’re generating.

Broadstar On Track to Sell 70 Turbines

Broadstar Rendering of AeroCam

When Maria Surma Manka brought us news of Broadstar Wind Systems last June from Windpower 2008, our interest was stoked, especially considering the fact that Broadstar was claiming that their AeroCam turbine could achieve $1 per watt installed.  Well, the company is still beta testing the AeroCam turbine, but demand is crazy and they’re "on track" to install more than 70 turbines.  J.C. Penny Co. plans to install AeroCam turbines on their distribution facility in Reno, Nevada by November this year.  Plus, 15 companies have contracted to test the turbines and 12 more are in talks.

Swedish Energy Ball Changes Look and Feel of Small Wind Tech

Prod_vindkraft

This technology by Swedish company Home Energy has taken the web by storm over the past couple days.  The Energy Ball is an aberration in a small wind market that seems to be dominated by vertical axis, helical, miniature, and three-blade designs.  It takes the shape of a puffed up flounder — with an orb of six blades and a fin to guide the orb towards the wind.

Solar Cell Tree Charger for the Home

Treecharger

This solar cell tree charger by Vivien Muller is kind of interesting.  You can use it to recharge your cellphone, camera, or whatever, because it has 54 tiny photovoltaic panels and an internal battery that stores energy.  The modular parts are connected and can be rotated infinitely creating a different tree for your favorite sunny spot at home.
