I have been having some success heating food on the engine mornings while I drive to work. I wouldn't try to "cook" really, and I wouldn't recommend driving around instead of using a more efficient oven. But I get a warm breakfast when I reach my destination. Kinda fun, actually.
EDIT: Oh, and I tried a crude estimate of energy "savings" in such a heating-up of leftovers scenario. The savings were miniscule. If I remember the rough and approximate numbers correctly it is something like this: if a stove burns on average 15,000 BTU/hour that might be equal to about .12 gallons gasoline per hour in your car. Make it 10,000 BTU/hr and .08 GPH. If 3 minutes to warm-up food on the stove then .004 gallons? My quick math-from-memory probably won't persuade... so correct or debate my estimates as needed/desired--or if there is even interest
Conclusion: not a significant energy saving strategy.
