Description

Technical Field

[0001] The invention relates to an energy production device. Background Art

[0002] The current hydrogen production method uses oil, natural gas, and coal as raw materials. A large amount of fossil mineral materials are consumed during the production process, and a large amount of greenhouse gas carbon dioxide emissions are generated, causing global climate change, affecting the global ecological environment, and being detrimental to the sustainable development of human society. There are electrolysis, chemical methods, biological methods, other physical methods, and nuclear energy methods to produce hydrogen energy using water as raw material. Energy sources that do not produce carbon emissions include solar energy, geothermal energy, nuclear energy with low carbon emissions, and other energy sources. The above-mentioned carbon-free energy sources have common disadvantages in the process of conversion and utilization, such as low energy density of energy sources, low conversion efficiency, large lighting area, and large land occupation. Nuclear energy hydrogen production consumes nuclear materials and produces nuclear waste.

[0003] The Earth where humans live has been constantly decomposing hydrogen and oxygen from water during the course of natural changes over the past hundreds of millions of years: earthquakes and volcanic eruptions, high-temperature magma decompose underground hydrogen and surface water into hydrogen and oxygen, resulting in combustion. When a hurricane passes over the sea, the huge kinetic energy decomposes seawater into hydrogen and oxygen, causing sea fires. Lightning and thunder with a temperature of tens of thousands of degrees in a storm decompose water in the atmosphere into hydrogen and oxygen, which burn and ignite forest fires on the ground. Early microorganisms, bacteria, viruses and primitive green plants on Earth used solar energy, water and carbon dioxide to generate a large amount of oxygen and a small amount of hydrogen. The above natural phenomena have been happening continuously since before the emergence of humans and in today's modern society.

[0004] Civilization began when ancient humans learned to use fire and water to put out fires, and a small amount of water would help combustion. Later, our ancestors used red-hot iron pipes to decompose water into hydrogen and oxygen, which then burned to generate water again.

[0005] Facts show that separating and producing hydrogen and oxygen from water is environmentally friendly, simple and easy, and has a variety of methods. Hydrogen can absorb, transform, and carry a variety of energy sources; thermal energy, light energy, electrical energy, chemical energy, bioenergy, as well as nuclear energy, radiation energy, sound energy, ultrasound, and shock waves. At present, there are many problems and difficulties in decomposing hydrogen and oxygen from water. The reason is that the cluster structure and chemical properties of water are very stable. It takes 237KJ of energy to decompose 1 ml of water, which is the energy of the hydrogen bond between hydrogen atoms and oxygen atoms, that is, the energy of changing the electron orbit of the atomic nucleus. In the actual utilization process, 1 kg of hydrogen and oxygen are produced from water, and combustion releases 140MJ of heat energy, which is the mineral fuel that releases heat energy of the same mass. Calculated at 50% thermal conversion efficiency, it is equivalent to consuming 5 kg of natural gas, 5.4 kg of oil, and 9 kg of coal. That is, the heat energy input of decomposing hydrogen and oxygen from water is much greater than the heat energy output. In the actual utilization process, there is still heat energy lost due to low conversion efficiency, that is, hydrogen production in water is beneficial to the ecological environment, but it will not produce economic benefits. Therefore, it is difficult to achieve large-scale, industrialized and practical use of natural energy to separate and produce hydrogen and oxygen from water. Summary of the invention
