Patent ID: 8881499

Claim:
Apparatus, including an underwater hydrogen and oxygen powered impulse engine, comprising: a programmable ignition system configured to implement and repeat an ignition cycle by providing hydrogen and oxygen into a combustion chamber, provide a pre-ignition energy to the igniter and also providing a control spark with a sufficient amount of energy for igniting a combustible mixture of hydrogen and oxygen; and a combustion chamber configured to be submerged in a surrounding aqueous fluid externally surrounding the combustion chamber, and also configured to: fill with a chamber aqueous fluid; receive the hydrogen and oxygen therein so as to displace the chamber aqueous fluid at the top of the combustion chamber and create a relatively dry pocket of the ignitable mixture of hydrogen and oxygen; receive energy from a pre-spark electrolyser circuit to remove moisture from the igniter; receive the control spark to ignite the combustible mixture of hydrogen and oxygen so as to cause a combustion reaction and form steam that yields a specific amount of heat energy, that rapidly expands in volume due to the rapid increase in temperature and that results in a substantial increase in pressure on the chamber aqueous fluid contained therein, provide the chamber aqueous fluid from the combustion chamber to the exhaust valve in response to the substantial increase in pressure on the chamber aqueous fluid contained therein, and transfer the heat energy from the reaction to the surrounding aqueous fluid in which it is submerged so as to cause a temperature differential to occur, thereby creating a vacuum therein and a difference in pressure inside the combustion chamber and the inlet valve, so that new chamber aqueous fluid can enter the combustion chamber via the net valve and substantially re-fills the combustion chamber based on the difference in pressure, and the ignition system can implement and repeat a new ignition cycle.
