Air Conditioner

Heat Engine / Heat pump / cryogenic refrigeration All of these are based on the same basic principles of thermodynamics and we will have a parametric set of options for machines that could accomplish all of them, and do them well!

Turbine based machinery
In order to refrigerate substances and later re-extract power from them it needed to use a pump / compressor / vacuum. The best way to do this is using turbine machinery. Turbine is a 3D model that when span up to high speeds generates a aerodynamic force on a fluid. This force over a area creates a pressure, and that is the basis of these systems. Turbines are cheap very effective and easy to make using 3d printing.
