Abstract: This invention provides an apparatus and a method for generating power from a flowing liquid. The apparatus has three main components. The first component is a control unit for selectively directing the flowing liquid to the second component, the power unit, which is responsible for generating power. The third component, a reversing unit, is used to adjust the control unit between two control unit configurations. The method involves the manner in which the liquid is passed and directed through the apparatus in order to generate power.

Abstract: An electrolytic gas generating apparatus for producing a combustible mixture of hydrogen and oxygen by electrolysis of water is disclosed, for particular use in a gas welding apparatus. The generating apparatus comprises a d.c. power supply 100 connected to electrolytic cells 200, a dehumidifier 400 for scrubbing the gas mixture generated by the cells 200, a gas regulator 500, a modifier 600 which modifies the combustion characteristics of the gas and a flash arrester 660. Gas generation is controlled by a main control board 800 in accordance with sensors which measure parameters to calculate indirectly the gas flowrate and control this in accordance with demand.
