Any absorption fridges that do not require 12 volts to run?

I'm thinking anything with a computer board which monitors stuff so you don't blow up in the middle of the night will require 12v.

So if you don't mind owning a fridge that can not shut off the propane when it senses a no flame condition or a high flame condition, then I bet with enough internet searching you'll find something out there with only an old school thermocouple.
