How #WindPower Works : When you talk about modern wind #turbines, you're looking at two primary designs: horizontal-axis and vertical-axis. Vertical-axis wind turbines (VAWTs) are pretty rare. The only one currently in commercial production is the Darrieus turbine, which looks kind of like an egg beater.
Using an automotive alternator to construct a wind-powered electrical generator can reduce or eliminate dependency on "grid" power, even if the wind turbine is only used for lighting or recharging batteries. The average backyard engineer can construct a wind power plant in about two hours.
