I've looked into this, but to do the whole house, your talking about the price of a small car. I'm still thinking about it, but I can't get the wife to agree. I've tried to convince her into getting a small one that can run some basic lights, etc, but even that was a no go :-) Actually, if I were to spend that amount of money, I may go solar power instead as that is something you can constantly use and slowly pays for itself over time. Unfortunately my house is all electric, so going completely solar is out of the question. However, I could power the whole house via solar with the exception of the major appliances.
