Abstract
A method and device that transfers heat to or from a gas. The method includes the steps of moving a surface with sufficient speed to disrupt a velocity boundary layer for molecules of the gas in contact with the surface, and cooling or heating the surface. The surface can be a heteroscopic structure that selects molecules from the gas. Cooling results in a transfer of energy from the molecules to the surface, whereas heating results in a transfer of energy from the surface to the molecules.
