How can I take energy from a camp fire and use it to cool my ice chest/ cooler.?

Question

Thermodynamics

Can't use a turbine.

Answer 1

using steam and a turbine are only practical for a large application, please dont try to make pressurized steam on a campfire, try to find a small refrigerator unit from a camper trailer that runs on propane, it would be possible to use campfire heat instead of propane to power the refrig unit, but only a small flame is needed, about the size of the average pilot light flame, or just throw some ice in and add a little sea salt, the salt melts the ice faster and absorbs the sensible and latent heat in the ice causing a colder cooler, same principal for making homemade hand turned ice cream.

Answer 2

Boil the water, use the steam to turn a power turbine then use the electricity to cool the ice chest. Simple plan that works all over the world.

Answer 3

Two thoughts:
1. Use the fire to make steam, with the steam driving a compressor for a fairly standard freon cooling unit.
2. Use the fire to heat and pressurize a coolant (like froen), then run the hot pressurized freon by an coil to cool, then through an expansion valve and another coil for the cooling, then back into the heating/pressurization chamber.
