Membrane filters with porosities of more than 70% have been proven to be useful for the fabrication of thermomechanical pumps (fountain effect pumps) with mass fluxes up to 1.7 g s -1 cm -2 at ~0.25 bar\* head of pressure. Different pumps made of 14 mm thick stacks of commercially available Sartoriu
