The present invention relates to a technique for pumping an aqueous fluid; and more particularly, the present invention relates to a method and apparatus for pumping water, including seawater. This invention also relates to a method and apparatus for making hot water for industrial, commercial and residential applications. This invention also relates to a method and apparatus of creating an engine which has only one cycle as compared to what is commonly known as a 2 or 4 cycle engine.

2. Brief Description of Related Art
By definition, an engine is a machine for converting thermal energy into mechanical energy to produce force and motion. The ability to move fluid in an upward vertical direction typically requires a mechanism known as a pump. Pumps are known in the art for pumping an aqueous fluid, including water. The majority of pumps are driven by either an engine, which are combustion based or a motor, which are powered by electricity. In all cases, pumps require an outside supply of energy to accomplish work. The majority of commercial mechanisms used to move fluid from one location to another location which is at a vertically higher than its current location is done through the use of pumps that operate on energy provided by the combustion of fossil fuels.
A significant percentage of the energy of used in this world is applied to moving fluids from one place to another. The energy required to accomplish this work can be replaced by other more abundant fuels. The method for accomplishing this work can be accomplished by utilizing an engine that is powered by hydrogen and oxygen.
In addition, creating hot water is commonly created by the combustion of fossil fuels and using the heat released to raise the temperature of the water. This method creates toxic emissions and carbon dioxide. Hot water can be created by other means, such as by renewable sources, but primarily it is accomplished by the use of fossil fuels.
In addition, most engines have pistons and they are typically known as either 2 cycle or 4 cycle engines which fundamentally perform in a similar fashion. Each has the ability to intake the fuel and air mixture (intake cycle), each has the ability to compress the fuel air mixture (compression cycle), each has the ability to transfer the energy released during the combustion reaction (power cycle), and each has the ability to remove the toxic emissions (exhaust cycle). It would be beneficial if the number of cycles and moving parts could be reduced.
In addition, imparting pressure upon a fluid results in a pressure wave being formed within the fluid. This pressure wave has certain characteristics that can be used to provide advantages in a number of applications. These pressure waves are typically created through the use of fossil fuels or via nuclear power plants. These methods have toxic and/or carbon dioxide emissions associated with them.
In view of this, there is a need in the industry to solve the aforementioned problem in the art.

providing a control spark with a sufficient amount of energy to ignite the combustible mixture of hydrogen and oxygen so as to cause a combustion reaction and form steam that yields a significant amount of heat energy, that rapidly expands in volume and that results in a substantial increase in pressure on the aqueous fluid contained therein,
so that the aqueous fluid is provided from the combustion chamber in response to the substantial increase in pressure on the aqueous fluid contained therein, the heat energy from the reaction is transferred through the walls of the combustion chamber to the aqueous fluid in which it is immersed so as to cause a substantial temperature differential to occur thereby creating a vacuum therein and a difference in pressure inside and the inlet portion of the apparatus, so that the combustion chamber is substantially refilled with new aqueous fluid based on the difference in pressure, and a new ignition cycle is implemented and repeated by the ignition system by providing new hydrogen and oxygen and a new control spark.
In effect, the present invention moves the aqueous fluids, such as water, in a dramatically different fashion and without any carbon emissions than previous devices by taking advantage of the chemical energy that is stored in hydrogen and the natural proclivity of the water vapor, which is created when combusted with the appropriate amount of oxygen, to condense into liquid water when it is cooled. When the appropriate amount of hydrogen and oxygen are combined and subsequently ignited inside a vessel, that has an opening on one end, which is submerged under water, or other aqueous fluid, which may be contained in another larger vessel of the appropriate size, the combustion reaction releases energy in the form of heat rapidly. The rise in temperature expands the resultant water vapor about 7-13 times the original volume of the original hydrogen and oxygen gases, thereby applying an explosive force to move the water out of the chamber via the outlet port. Because the chamber is underwater the resultant water vapor cools rapidly and the water vapor (steam), reduces its volume by natural means and condenses into liquid water, thereby creating a vacuum to refill the original chamber with water again, so the cycle can be repeated.
In operation, the combustion portion of the present invention may be configured to work underwater consistent with the following features and/or advantages:
1. Water or other aqueous fluid may be used as a cooling component to improve the efficiency and effectiveness of the present invention.
2. The water or other aqueous based solution may be used as a working fluid.

5. By cooling the combustion chamber, by having it submerged under water, a relatively large vacuum is created and the water, or other working fluid, is forced to enter the combustion chamber without the use of additional energy.

a through 2d show, by way of example, the present invention in the form of apparatus generally indicated as 10, including an ignition system generally indicated as 12 and a combustion chamber generally indicated as 200, which resides in water or other aqueous heat conducting fluid indicated as 300. This fluid 300 is contained inside a vessel indicated as 310. The basic components of the apparatus, according to some embodiments of the present invention, operate as follows.
As shown, the combustion chamber 200, also known herein as a cylindrical vessel, of an appropriate shape and size 200 is submerged under aqueous fluid, e.g., water, 300 vertically upside down as shown in
The present device or apparatus may be configured to use standard valves, 240, 250, commonly known swing check valves that may be arranged to take advantage of gravity so each valve 240, 250 may be seated when in the vertical position. The valves 240, 250 may be configured to be free to react to the forces applied to them. Each valve 240, 250 may be positioned so they operate in the same direction, generally moving the water or other working fluid from the intake side to the exhaust side. By using swing check valves by no means eliminates the use of other types or kinds of check valves to perform the specific task, and the scope of the invention is intended to include using other types or kinds of valves and check valves, either now known or later developed in the future.
The basic principle of operation is as follows:
Initially, as shown in
As shown in
As shown in
When the ignition event occurs, the combustible mixture of hydrogen and oxygen combine to form water molecules, also known as steam, and the reaction yields a significant and specific amount of heat energy which according to well-known scientific principles, rapidly expands in volume and since the reaction occurs inside an enclosed or substantially enclosed combustion chamber or vessel 200, it results in a substantial increase in pressure upon the all of the-materials in communication with the original gases. Since the combustion chamber or vessel 200 and related components 201, 210, 220, 230, 250, are resistive to the forces of expansion impinging upon it, the resultant pressure of the expanding gases which were in contact with the surface of the water, or other aqueous based fluid, force the water or other aqueous based solution out of the opening 202 in the bottom of the combustion chamber or vessel 200 and through the exhaust port 260 and exhaust valve 240 and into the manifold 280. These expanding gases which act upon the aqueous based fluid that may desire to exit the chamber 200 and 202 through inlet port 270 force the inlet valve 250 closed. This action forces the water or other aqueous fluid out the exhaust valve 240 The amount of water or aqueous based fluid moved at this instant is dependent upon factors such as pressure, volume of gases, temperatures, etc., as a person skilled in the art would appreciate.
As shown in
It is known that the volume of steam and pressure produced are directly related to the amount of hydrogen and oxygen injected in the chamber 200, the temperature achieved during the reaction and the size, shape and material of the combustion chamber or vessel 200. Basic physics support the fact that any release of energy must be converted into either force or heat as a person skilled in the art would appreciate. Due to the fact that the combustion chamber or vessel 200 is under water 300, there is a significant ability for the heat portion of the reaction to be transferred very rapidly through the walls of the combustion chamber or vessel 200 to the surrounding water 300. This ability to transfer the heat portion of the reaction is a significant advantage according to some embodiments of the present invention. It is also known, based upon fundamental principals of science, that any amount of cooling that occurs within the combustion chamber or vessel 200 will reduce the volume of the steam from its maximum to whatever the temperature of the surrounding environment and therefore, and create a relative vacuum (lower pressure) rapidly within the combustion chamber or vessel 200. The amount of vacuum can be calculated and therefore controlled, quite accurately if the temperatures, volumes and relative pressures are known. According to some embodiments of the present invention, the mechanical portion of the engine, because the combustion chamber or vessel and related components, e.g. elements 200 through 280, is submerged under water 300, the heat of the reaction is transferred very rapidly through the walls of the vessel to the water or other fluid surrounding it, thereby allowing a large temperature differential to occur rapidly and the result is a vacuum (low pressure) being created rapidly inside the combustion chamber 200, 201, 202, 230, 260, 270.
When this portion of the reaction is initiated, the one way valve on the exhaust side 240 of the engine or apparatus 10 closes, and the one way valve on the inlet 250 opens. The vacuum creates another pressure differential on the water or, other working fluid, on the inlet side 270 of the engine and thus fresh cooler water or other aqueous based fluid is forced into the combustion chamber or vessel 200 via 280, 270, 230, 202 until it is substantially full again. Any water or other aqueous based fluid, that enters the inlet side of the engine (see reference label 270) but exceeds the available volume of the combustion chamber or vessel 200, may be forced to continue moving through the exhaust valve 240 and into the manifold 280. This act of refilling the combustion chamber constitutes a significant advantage of this invention because, it cools the combustion chamber, without using any additional energy, which also helps to maintain or enhance the desired material characteristics of the chamber 200.
At the end of that portion of the cycle, the engine or apparatus 10 is at a state of relative rest and the cycle is free to be repeated, see
According to some embodiments of the present invention, the combustion chamber or vessel 200 may be configured or modified to focus the force of the reaction toward the opening 202 of the combustion chamber or vessel 200.
According to some embodiments of the present invention, the combustion chamber or vessel 200 may be configured or modified to limit or restrict the amount of water or other aqueous based fluid re-entering the combustion chamber or vessel 200 after the initial ignition occurs.
According to some embodiments of the present invention, the combustion chamber or vessel 200 may be configured or modified to maximize the heat transfer to the surrounding water 300.
According to some embodiments of the present invention, the combustion chamber or vessel 200 may be configured or modified to enhance the amount of fluid being provided toward the opening 202 of the combustion chamber or vessel 200.
According to some embodiments of the present invention, the electronic control module (see element 14) system comprised of elements 20, 30, 40, 50 can be modified to control the temperature of the combustion reaction inside chamber 200.
By way of example, the following is a list of components of that shown in
Power supply 12 volts. Maybe powered by, e.g., an electrical sub system (not shown).
One skilled in the art would appreciate that typical spark plug igniters used in internal combustion engines may be configured to operate in a low moisture environment.
The underwater hydrogen and oxygen powered hydraulic impulse engine or apparatus 10 exposes an igniter 130 to moisture from two (2) sources. The first source is water produced by the combustion of hydrogen and oxygen during the operation of the device. The second source of water is the water content of the working fluid within the combustion chamber 200.
With a typical high voltage ignition system (i.e. such as in an automobile), moisture on an insulator 131 of the spark plug igniter device 130 will create a path to ground 135 attenuating or eliminating the desired ignition spark and detrimentally affecting the ignition of the fuel mixture. Furthermore, droplets of water bridging a high voltage electrode 132 of a spark gap 133 on the igniter 130 also creates a path for the high voltage to the ground 135 without producing the desired spark required for ignition of the hydrogen and oxygen mixture.
According to some embodiments of the present invention, the ignition system 12 (see also
