Thanks for all those speedy replies.
Of course, once gas is gone, cars would be seen as scrap and suddenly we have a massive resource of machined parts, wheels, pulleys, flywheels,
electronics etc. I hadn't looked at cars that way - hiding in plain sight!
With regards to thermo-electric effects, I did find this on ferroelectric materials that generate current at as little as 10 degrees centigrade temp
but that's hardly survival stuff!
So if we look at the idea of using car bits, then the question is simply "how to turn the shaft". Water, wind and sun are the obvious candidates,
but are very time and location specific.
I think there is something worth discovering or uncovering in regards to v. small temp differences. For example, surface temp where I live ranges from
-5 to +35 during an average year, but only 2.5m down, it's a fairly stable 15-18 degrees.
Even if it's horribly inefficient, if there's a way to 'turn a wheel' using this temp gradient, then electricity could be generated and stored by
automobiles, which almost every household in the developed world has 'sitting in the driveway'
