I have been looking into converting a diesel engine to run on used cooking oil. Now I am thinking about linking this idea to an electric car. A portable diesel-powered generator producing 220V at 4,000 watts continuous output would fit the engine compartment and weigh 180 pounds. Are there AC motors out there that could drive my car with that kind of power. Would this eliminate the need for lots of batteries. I'm thinking about using a 1999 Plymouth Voyager which would have many of the same advantages as the small pick up trucks. The diesel generator will fit in the engine compartment. What do you think?
