With energy prices through the roof, taking advantage of the elements around you to supplement your power needs seems like a pretty smart idea. That's the thought behind the Skystream 3.7 wind generator, the first wind-power generator designed for residential houses. Looking similar to a regular streetlamp, you simply install it, pray for a strong breeze, and watch as your energy costs drop dramatically. It sets up to work with your normal energy provider, merely supplementing your current setup rather than replacing it completely. Costing between $8,000 and $10,000 to get installed, it should pay for itself after 5 to 12 years, depending on how windy your area is and how much juice you're sucking up. And with all the negative effects our energy consumption are having on the environment becoming impossible to ignore, doing your part to curb the damage you're doing really is priceless.
