Amazon now carries a 400-watt personal wind turbine. The Sunforce 44444 12Volt 400-Watt Wind Generator (wow thatâ€™s a long name) is ideal for cottages, 12V battery charging, remote power, back-up power, and hobbyists. There are only two moving parts, making installation easy and the unit maintenance free. The blades are made of a carbon fiber composite for low wind noise, and the body of lightweight cast aluminum, featuring patented high wind over speed technology. The fully integrated regulator automatically shuts down when the batteries are charged to minimize wear. The turbine is completely weatherproof (thankfully, it is designed to go outdoors), and delivers maximum power of up to 400 watts or 27 amps in ideal conditions (like a hurricane). Hopefully weâ€™ll start to see more products like this in the future that cut electricity costs, help the environment, and move people â€œoff the gridâ€.
