And this is a little easier, more off the shelf, approach: http://hiwaay.net/~bzwilson/prius/priups.html Richard's approach has a lot going for it including a 3 kW capability. The other approach provides laptop power during trips and 1 kW mobile emergency power. Different approaches but both based upon the unique capabilities of a Prius. Bob Wilson
Toyota is working on it. They have several test vehicles doing just that. Can you imagine thousands of Prii in a disaster area providing power to homes and businesses. I have a 1.2 KWH generator at home I would love a 3 KWH generator. I am ready to go with a cut off switch. I could run everything at home. As it is now I have to make compromises.
