Abstract: An electrochemical conversion system 10 is disclosed having a housing (11) which includes boiling chamber (12), a cell holding block (13), and a condensing chamber (14) coupled by conduits. The system also includes an electrochemical cell (23) mounted within the cell holding block, a heater (24) mounted in thermal communication with the boiling chamber, and a cooler (25). With the energization of the heater a portion of the working fluid is heated to a vapor state so as to create a high total pressure with a low partial pressure of hydrogen gas upon one side of the electrochemical cell, while simultaneously a high partial pressure of hydrogen gas is developed on the opposite side of the cell. The hydrogen partial pressure differential across the cell causes an electrical potential across the cell as hydrogen migrates across the cell.

Abstract: An air pump (10) having a separation chamber (15) defined by a top wall (11), a bottom wall (12) and generally annular side walls (13). A liquid entry tube (24) configured to draw air into a stream of liquid passing through the liquid entry tube is coupled to the separation chamber so that the air/liquid mixtures rotates within the separation chamber. The rotation of the mixture causes air to accumulate within a central zone (30) and the liquid to accumulate about a peripheral zone (31). The continued flow of the mixture causes the accumulating air to become pressurized where it is released through an air exit tube (20) in fluid communication with the central zone of the separation chamber. The liquid is expelled through a liquid exit port (18).
