Bubble capture electrode configuration

A magnetohydrodynamic system, comprising:

• a main body portion forming a main channel, wherein the main channel holds an electrically conductive fluid adapted to flow therethrough;
• at least one shaped body portion extension defining at least one auxiliary channel extending from the main channel and containing electrically conductive fluid;
• at least two electrodes wherein one is a cathode and the other is an anode, the electrodes positioned substantially adjacent the body portion and adapted to transmit an electric current flow therebetween and through the fluid in the main channel, at least one electrode of the at least two electrodes interacting with the fluid and producing an electrolysis reaction which creates gas bubbles in the fluid substantially adjacent the at least one electrode, said at least one electrode being positioned within said at least one auxiliary channel;
• means for forming a magnetic field which passes through the fluid in the main channel substantially transverse to the electric current flow and generates a force for moving the fluid through the main channel;
• means for substantially preventing the gas bubbles produced substantially adjacent the at least one electrode from moving from the at least one auxiliary channel and into the main channel so as to substantially prevent interference by the gas bubbles with flow in the main channel.
