is to be understood that all non circular cross sections are embraced within the scope of this disclosure that is the conduits and electrodes can have an elliptical cross section and the like or a polygonal cross section fig2 schematically illustrates a conduction pumping mechanism 50 used in association with a liquid guiding channel 51 in this embodiment the grounded electrode 52 is a plate oriented flush with the bottom surface 53 of the channel 51 the high voltage electrode 54 is connected by an electrical connection 56 to a high voltage source v in this particular embodiment the high voltage electrode protrudes into the interior of the channel and both electrodes 52 and 54 are configured to be oriented within the liquid fig2 is similar to fig2 except that the high voltage electrode is a pair of parallel plates 57 extending parallel to the longitudinal axis of the channel 51 and to the bottom surface 53 of the channel 51 fig2 is similar to fig2 except that the high voltage electrode 58 has a rounded surface configuration as compared to the more rectangular version illustrated in fig2 fig2 schematically illustrates a vessel 60 housing a liquid therein with a grounded ring electrode 61 oriented so that the interior surface thereof is flush with the interior surface 62 of the vessel 60 an elongate bar 63 is oriented inside the vessel 60 and is configured to serve as the high voltage.
