| 摘要 |
A gas pump comprising of a porous material or capillary tube(s) that uses a chemically reactive material added to the pumped gas for the purpose of generating, upon reaction, a temperature gradient across said porous material or capillary tube(s) and thereby sustaining the thermal transpiration pumping process without an external heat or cooling source is described. Means for coincident pumping of non-reacting gas streams, multiple-stage pumping for higher gas pressures, coincident electrical power generation, and ignition of the reactive material are presented.
