Abstract:
1. An electrochemical engine for buoyancy, said engine consisting of: a chamber having an expandable membrane within and at least one vent penetrating said chamber to an environment outside of said chamber and at least one fluid inlet penetrating said chamber; a volume of seawater as an electrolyte fluid contained in said chamber; and a pair of electrodes disposed in said volume wherein one of said electrodes is an anode of magnesium material and another of said electrodes is a cathode of platinum material such that a difference in galvanic potential in seawater is more cathodic as −1000 millivolts as compared to a saturated calomel electrode; wherein electrons are donated from said anode for reduction of hydrogen protons in said volume and generating an amount of hydrogen gas on a surface of said cathode by a reaction 2H wherein said chamber comprises a pressure relief valve fluidly connected to said chamber wherein said relief valve is capable of relieving pressure from said chamber to the outside of said chamber.
