Here's something I have to try: reusing some waste heat in from your engine bay to cook a meal on your way home. There would seem to be several advantages to this type of cuisine. For one thing, it clearly saves the energy I would otherwise expend in the oven to let my gas guzzling truck roast up some tenderloin and root veggies during the evening commute. True, I might offset some of those car-bon credits driving further to cook something really big, but think of all those Thanksgiving birds that could be basted to perfection all snuggled up to engine blocks on the way to Grandma's. Now I know from experience that the striker plate on the inside of the car door can double as a bottle opener, and I've used the handle of a Land Cruiser car jack to spit roast a road killed Guinea fowl, but this takes take out food to a whole new level.
