The agency I work with used to use generators in the field sometimes. The favorite was by far the Hondas, because they were very quiet, and light weight. They're also expensive. Being around a noisy generator is a pain, though.
Using a car as a power source isn't a bad idea, but most cars probably don't have enough 12V capacity at idle to run more than a couple of hundred watts. (I'm betting that dual tank pickup had an extra duty alternator.)
On food - A mistake I made was checking out the food, and checking out the stove, but not the two together. If you have a camping stove, you should try cooking some of your survival food on it, at least if your cooking talents are as poor as mine. It was tricky keeping things boiling w/o overflowing, thickening sauces w/o burning, etc. Oh, and don't forget to try cleaning the dishes w/o power, too!
Thanks for the "drops" info, I'll look into that.
Now a question for you solar guys: How could I make enough juice in our dingy New York winters to power a radio or LCD TV, or charge some AA's? Without spending a fortune?
