I've just come through the Great Texas Cold Snap, during which I was very fortunate to lose neither power nor water. However, I did get to wondering what I'd do if the power did go out. I don't have a generator, except... I do. My car is a very powerful and quiet generator. But the only way I can see to take advantage of that power outside the vehicle is through one of the 12V/10A outlets. Well 120 watts is never even going to heat a single room. Can anyone think of a way to get a kilowatt or more out of an idling Optima siting out in the cold outdoors?
