    Looks cool but I do not see anywhere where it says how much power it produced.

    To give you an idea, this link is for a wind turbine that produces 2.5 KW of electricity sustainergy - Wind systems from Sustainergy

    Ok so what? What's that mean? Well, on my boat I'm currently using a 3.0 KW Westerbeke generator. With that I can power almost everything on my boat. I can run a small Air conditioning system, lights, small refrigerator, radios, outlets for laptops or TVs and a microwave oven. I cannot run the AC and the water heater or the electric stove at the same time. So, 2.5 KW will do roughly the same.

    The $200 project does less than that. That said, if you can hook up a free (to operate) do-hickey and have it cut your electric bill, more power to you!

    Sound then with a couple of them you could probably power your hole house, not bad.

    You would need a battery bank and DC wiring... I've been running the numbers and havent been able to configure a system for under 2k..

    Why would you need batteries?

    Here in Virginia the utility is required to buy power from you, so your meter just runs backwards.

    You would only need batteries if you wanted to be off the grid completely. If you stayed on the grid you would not need any. You would simply use power off the grid when the wind was not blowing enough to generate power, and at those times you generated more power than you need, you could get the Power company to buy the extra power. As I under stand it that is Law in most places.

    Keep in mind however that this is just and fancy advertisement for a wind mill. I would not just accept everything it says about the product at face values.

    Wind generators do not provide a steady stream of electricity.. They work as a trickle charger but you will still need capture the energy in batteries. I 've not heard of a direct AC generator either... You would need to convert the stored power from DC to AC unless you were going to wire the house in DC.

    You're right. In my research, if you were going to go off-grid, you would need a bank of batteries to charge to take advantage of all the electricity you produce from all your sources (Solar, wind and micro-hydro). You would need to size the battery bank to roughly 4x the size of the required load so that you never allow your batteries to dip below 50% charge (deep cycle which reduces the life of the battery). If you can keep your charge in the 60%-80% range, you would be doing well for yourself.

    You would then need inverters of appropriate size to convert the DC batteries to the AC of your house, unless you were going to rewire for DC. You would further want to look at every appliance running in your house for the greatest efficiency. And then there's Air Condidtioning.....lol.
