Abstract: The present invention relates to systems and methods for pumping or removing a fluid from a region within or on top of or in contact with a water or liquid body and applications for said systems and methods. Some embodiments may be applicable to, for example, inhibiting or preventing growth formation or fouling of structures in liquid environments. Other embodiments may be applicable to, for example, an energy storage device or a tidal power energy generation system.

Abstract: Apparatus includes an ignition system that repeats an ignition cycle by providing hydrogen and oxygen and also provides a control spark with a sufficient amount of energy for igniting a combustible mixture of hydrogen and oxygen. The combustion chamber is immersed in an aqueous fluid, fills with the same or other aqueous fluid, receives the hydrogen and oxygen therein, receive the control spark to ignite the combustible mixture of hydrogen and oxygen to cause a combustion reaction to occur and form steam that yields a specific amount of heat energy, and provides the aqueous fluid from the combustion chamber in response to the substantial increase in pressure on the aqueous fluid contained therein.

Abstract: A vacuum assisted bilge pump small enough for the crowded spaces below decks in the engine and pump room of a boat which can also function as a transfer pump, a crash pump and a fire extinguisher. The pump comprises two chambers and is internally configured to aid in the separation of gas and liquid increasing pump throughput.

Abstract: Pressurized medium delivery device with a pump, a suction pipe, at least one pressure pipe and a pressurized medium supply volume in a pressurized medium supply container.

Abstract: A fluid pressurizing system and method according to which a fluid at a low pressure is compressed by fluid to increase its pressure to enable it to be discharged from the system and to an external delivery point.
