I've just designed and built a practical, portable 12 Volt 17 Watt wind generator that is ideal (and appropriate) for setting up in campgrounds, parks, Earth Day exhibitions, research stations, and third world homesteads. On "light breeze" days (5mph = 2.2m/s) when most wind generators are becalmed, this light-and-nimble unit reliably generates power, at charging levels, fully taking advantage of the erratic, gusting winds that are so common in near-ground conditions.

Camping Wind Turbine

Camping's all about enjoying the outdoors; but let's face it - electronics are hard to power in the outdoors...There's nothing worse than pulling out your camera to snap a photo of a great view and finding out your battery's dead! Generators are heavy and difficult to lug around, and so the perfect solution is a green source of free energy: the wind! Although this turbine -because of its small size and lightweight nature- isn't exactly going to run at 120V, it's capable of charging batteries and such.
