Low-MPH wind turbine designed with the home in mind

Here's an interesting wind turbine designed for the residential market.

One of the knocks on residential wind power is that it doesn't work at low speeds. Well, this one is said to work at speeds as low as 2 miles per hour.

It costs about $4,500 and delivers up to 2,000 kilowatt hours a year for locations with Class 4 - or very good - breezes. It's made by WindTronics, based in Muskegon, Mich. Learn more here.

Of course it's hard to find exactly how much electricity the wind turbine will produce at low winds.

The device, which weighs 95 pounds and is six feet in diameter, can be mounted on rooftops, attached to chimneys, or put on a pole. WindTronics says it hopes to sell the turbines through Ace Hardware stores.

How about Costco? That's where I do my shopping.
