Post Apocalyptic Refrigeration


Post Apocalyptic Refrigeration

There are many options to do refrigeration with simple technology
one option is a Hilsch vortex tube — you could use a water wheel to power a compressor to provide compressed air to the cooling system using a Hilsch vortex tube for cooling

Another option is a ice ball cooler — simply 2 containers under pressure with ammonia and water inside heat one container to boil off the ammonia – and cool the other with water … then when you take the heat away the water will freeze around the second container.
