Abstract
There is disclosed an apparatus and method for pumping a flowable medium. The pump forces a volume of medium out a pumping chamber by driving an induced plasma arc the length of the pumping chamber from inlet to outlet. An electric potential generated across the medium within the pumping chamber creates the plasma arc near the inlet of the chamber. An induced magnetic field then causes the plasma arc to travel from inlet to outlet thereby forcing the medium ahead of the plasma arc out of the chamber.
