Description
Technical Field

Background
Hydrogen is one of the most ideal energy sources in the 21 st century, the hydrogen generates the most energy under the condition of burning coal, gasoline and hydrogen with the same weight, and the combustion product is water without ash slag and waste gas, so that the environment is not polluted; the combustion of coal and oil mainly produces CO2 and SO2, which can produce greenhouse effect and acid rain, respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which can continuously generate hydrogen and never use up. The distribution of hydrogen is very broad and water is a large "warehouse" of hydrogen, containing 11% hydrogen. About 1.5% hydrogen in the soil; petroleum, coal, natural gas, animals and plants, etc. contain hydrogen. The bulk of hydrogen is in the form of compound water, and about 70% of the earth's surface is covered with water, which is a large storage of water, and thus hydrogen is an "inexhaustible" energy source.
