A self-draining, valve for fluid flow control. In an exemplary embodiment of the invention, the method includes generating plasma from a gas species to produce a plasma exhaust. The heat from the combustion of the first portion of the oxidizer is then transferred to a second portion of the pumped oxidizer to convert the second portion of the oxidizer to a super-heated gaseous oxidizer. When the field rotors rotate relative to each other electrical energy is generated. In an embodiment, the processor can be further configured to store the video-on-demand content in a mass storage.
