Windspire

The Windspire is a home 'energy appliance,' being touted by Mariah Energy as low-impact, quiet, attractive and inexpensive. The turbine has an extremely low footprint and generates power in only 8 mph winds.

However, we're not so sure our neighbors would be OK with us putting one of these things up. It might be quiet, but it's also thirty feet tall, taller than almost anything man made in most residential neighborhoods. But it does produce a good amount of energy (rated at 1 kilowatt) with a tiny footprint. And, when it comes out in a few months, it will be one of the cheapest wind power solutions on the market at only $4,000.
