     BACKGROUND OF THE INVENTION 
     1. Field of the Disclosure 
     The present invention relates to a HHO generator (hydrogen/oxygen generator) which generates gases from an aqueous solution. A Zeer pot is configured to reduce the temperature inside the HHO generator by evaporation of water on the surface of the Zeer pot. 
     2. Description of Related Art 
     In light of dwindling supplies of natural resources and global warming, there has been motivation to find alternative and sustainable power sources to condense harmful emissions from internal combustion engines and to supplement the hydrocarbon fuels that are burned in them. A hydrogen economy is proposed, which consists of delivering energy using hydrogen. Hydrogen produces water as a by-product, is high in energy, and yet an engine that burns pure hydrogen produces almost no pollution. Furthermore, electrolysis of water, an abundant natural resource, produces hydrogen. However, in order to replace carbon-based fossil fuels, an entire manufacturing and distributing network for hydrogen must be created. 
     Proponents of a hydrogen economy suggest that hydrogen is an environmentally cleaner source of energy. Thermodynamically, generating hydrogen and oxygen by electrolysis of water requires more energy than is produced from regenerating water by burning the hydrogen and oxygen. However, when supplemental hydrogen and oxygen is added to an internal combustion engine, there is an increase in efficiency and a reduction in emissions, because the supplemental hydrogen and oxygen enables the engine to burn the hydrocarbon fuel more efficiently. 
     Another concern is maintaining electrolyte level and temperature within desired limits in the hydrogen generator. Therefore, a demand still exists not only for a practical electrolytic hydrogen generator for an internal combustion engine, but also a hydrogen generator used as an energy storage medium, in which electrolyte levels and temperature can be controlled. 
     BRIEF SUMMARY 
     The present invention provides a safe and practical hydrogen/oxygen generator to generate gases from an aqueous solution.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates a system according to the present invention. In this embodiment, the system comprises a HHO generator ( 1 ), a Zeer pot ( 2 ) configured to reduce the temperature which is inside the HHO generator ( 1 ), water inside the Zeer pot ( 2 ), and a radiator ( 3 ) inside the Zeer pot ( 2 ) which cools an electrolytic solution for the HHO generator ( 1 ). The system produces hydrogen and oxygen by evaporation of water, which is then delivered to an engine ( 4 ). 
     The HHO system has a water reservoir ( 5 ) that holds water, preferably distilled water. The reservoir ( 5 ) compensates the water that goes inside the HHO generator ( 1 ) through a one-way valve ( 6 ), because the electric interaction of the electrolyte produces a shortage in the amount of distilled water inside the generator ( 1 ). Therefore, the reservoir ( 5 ) compensates for the shortfall of distilled water inside the HHO generator ( 1 ). 
     The water inside the reservoir ( 5 ) does not communicate with the water inside the Zeer pot ( 2 ). The lack of water inside the Zeer pot ( 2 ) is either compensated manually, or a float ( 7 ) and valve water are installed. The Zeer pot ( 2 ) contains tap water. The purpose of the float ( 7 ) is to show the lack of water inside the Zeer pot ( 2 ). The volume of water inside the Zeer pot ( 2 ) and the reservoir ( 5 ) depends on the system&#39;s size, in order for production of hydrogen and oxygen gas. 
     The Zeer pot ( 2 ) is preferably constructed of natural clay. The Zeer pot ( 2 ) constructed of natural clay displays to high temperatures to form small pores to evaporate the water. These pores cause the water to evaporate through the Zeer pot ( 2 ) surface. The sizes of the pores vary, depending on the clay material and temperature. 
     Porosity of the natural clay Zeer pot ( 2 ) may be essential to the cooling element of the Zeer pot ( 2 ) depending on the weather and temperature. For example, in high temperatures, such as 50° C., it is recommended for the porosity of the natural clay to be larger than if the weather temperature is low. 
     A thickness of the Zeer pot ( 2 ) depends on the weather and temperature. For example, in high temperatures such as 50° C., it is recommended for the Zeer pot ( 2 ) to be thinner than if the temperature is low. 
     The reservoir ( 5 ) tank is positioned at a higher elevation than the HHO generator ( 1 ), because the entire HHO generator ( 1 ) has to be fully covered by solution. Further, this positioning makes water shortage easily noticeable. If the reservoir ( 5 ) tank is positioned at a lower elevation than the HHO generator ( 1 ), the generator ( 1 ) will not produce hydrogen and oxygen gas because the generator ( 1 ) will not be fully covered with solution, and water shortage in the generator ( 1 ) will be unnoticed. 
     A solution in the HHO generator ( 1 ) is cooled by circulation through the heat exchange, which is inside the Zeer pot ( 2 ), in which the solution is contained inside a radiator ( 3 ) with inlet and outlet ends connected to the HHO generator ( 1 ). The HHO generator ( 1 ) contains an electrolyte and distilled water. The electric exchange process includes steaming distilled water and converting it to hydrogen gas. The remaining electrolytic solution speeds up the power exchange. 
     Through the electric exchange process in the HHO generator ( 1 ), there is heat production in the solution. The solution moves through the pump ( 8 ) to the radiator ( 3 ), which is located inside the Zeer pot ( 2 ). Heat transfers through the heat exchange through the radiator ( 3 ) and the water inside the Zeer pot ( 2 ). Therefore, the solution absorbs the coolness from inside the Zeer pot ( 2 ) and moves to the HHO generator ( 1 ). 
     The electrolyte in the solution is sodium hydroxide or potassium hydroxide. The electrolyte is preferably potassium hydroxide, because it does not lead to iron rust, and the coefficient electric exchange is high. The distilled water for the generator ( 1 ) is compensated by the reservoir ( 5 ) tank. However, the electrolyte in the generator ( 1 ) does not need to be replenished. 
     The generator ( 1 ) contains an inlet and outlet to communicate with the radiator ( 3 ) in the Zeer pot ( 2 ). The inlet and outlet circulate the solution through the generator ( 1 ) in a cooling loop to counteract the effects of electrical heating. The heated fluid is drawn from the reactor through the outlet to the inlet of the pump ( 8 ). Then, the fluid is pumped through the radiator ( 3 ) where it is cooled and subsequently returned through the inlet to the generator ( 1 ). 
     Heating the solution excessively results in a loss of ability to conduct electric current, which limits hydrogen and oxygen production via electrolysis. Therefore, the radiator ( 3 ) enables the employment of higher electrical currents which, yields larger quantities of hydrogen and oxygen. In one embodiment, the system is configured to operate for extended periods at high amperage. Cooling the radiator ( 3 ) consumes larger amount of electricity to produce larger amounts of hydrogen and oxygen gas. By cooling the solution, the system may operate at twice the amperage. Increasing electricity without cooling the solution will result in water vapors, which will affect the engine ( 4 ). 
     The demister ( 9 ) separates the water steam from the gas, so in case there is steam water coming from the generator ( 1 ), the demister ( 9 ) will separate the steam from the gas before the steam goes into the engine ( 4 ), in order to protect the engine ( 4 ). There is a one-way valve ( 10 ) between the generator ( 1 ) and the demister ( 9 ). 
       FIG. 2  illustrates a system according to the present invention. In this embodiment, the system comprises a HHO generator ( 1 ), a Zeer pot ( 2 ), a radiator ( 3 ) and water inside the Zeer pot ( 2 ), and a fan ( 11 ) which is installed above the Zeer pot ( 2 ) to blow downward to the surface of the Zeer pot ( 2 ) to promote evaporation of water from the Zeer pot ( 2 ). The hydrogen and oxygen gas produced are then supplied to an engine ( 4 ). 
     The fan ( 11 ) helps evaporate the water on the Zeer pot ( 2 ) surface and dry the evaporated water, thereby making the surface cold. Then, the surface helps cool the water inside the Zeer pot ( 2 ), which will cool the radiator ( 3 ) inside the Zeer pot ( 2 ). The radiator ( 3 ) then cools the solution inside the radiator ( 3 ), which in turn cools the solution inside the HHO generator ( 1 ), causing high production of HHO gas. 
     The fan ( 11 ) at the top of the Zeer pot ( 2 ) drags the air and passes it onto the Zeer pot ( 2 ) surface. The air works on the evaporation of water on the surface of the Zeer pot ( 2 ) and thus becomes a heat exchange, which works on cooling the water inside the Zeer pot ( 2 ). The fan ( 11 ) is preferably an axial-flow fan. 
       FIG. 3  illustrates a system according to the present invention. In this embodiment, the system comprises a HHO generator ( 1 ), a Zeer pot ( 2 ), a radiator ( 3 ) and water inside the Zeer pot ( 2 ), and a fan ( 11 ) which is installed with a top of the Zeer pot ( 2 ), in which the outer container encompasses the HHO generator ( 1 ) and the pump ( 8 ). The hydrogen and oxygen gas produced are supplied to an engine ( 4 ).
