From 2020 there will be an engine using water as fuel.
Extracting hydrogen from water and using it as fuel has been the focus of scientists' efforts for many years, especially now that the shortage of fossil fuels such as oil has become increasingly more importantly, the importance of this research has been increased. attracted a lot of people's attention.
As early as 2008, a Japanese company called Genepax developed a car that uses water and air as fuel. The car uses a technology called a membrane electrode array to split water into hydrogen and oxygen to propel the car forward without producing polluting gases.

Genepax announced its new research and development model in Osaka on June 12, 2008. This voiture you It takes 1 liter of water to run at a speed of 80 kilometers per hour for one hour, and any water can be rain, river water or sea water.
“As long as you put a bottle of water in your hand and add it, it can work,” said Kiyoshi Hirasawa, CEO of Genepax.
Genepax explained that it uses a new fuel cell system technology called a “hydraulic power system”.
Use water as fuel without emitting carbon dioxide. This system supplies external water and air to the fuel cell and air electrode, respectively, thereby generating electricity.
The company said at a press conference held at Osaka Kaikan on June 12 that the basic electricity generation principle of this system is similar to that of a fuel cell. to ordinary hydrogen when water is injected into the water tank. located at the rear of theIn a car, a generator inside will split the water and use it to produce electricity.

Thermal power plants, nuclear power plants, hydroelectric power plants and pumped-storage energy production The factory's production process? Please be more detailed, thank you
Firepower:
Advantages: The technology is mature and the current cost is low. Low geographic environment requirements.
Disadvantages: high pollution, poor prospects for sustainable development. It consumes a lot of energy and has low efficiency.
Hydraulic power:
Advantages: long history, low subsequent costs. No pollution, renewable water energy, large total water energy reserves.
Disadvantages: significant capital investments and requirementslifted in terms of geographical environment. For example, southwest China is extremely rich in water resources, but the natural environment is harsh and construction is difficult, making its use impossible. them.
Detailed information:
The basic principle of hydroelectricity is to use the difference in water level to produce electricity with a hydroelectric generator, that is, the potential energy of the water is converted into mechanical energy of the water wheel, and then into mechanical energy. mechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively use fluid engineering and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use an electricity cheap and pollution-free.
Thermal power generation generally refers to the use of thermal energy generated when fuels such asoil, coal and natural gas are burned to heat water, turning the water into water vapor at high temperature and high pressure, and then use the water vapor to drive a generator to produce water. 'electricity. The general name of the method. Power plants that use coal, oil, or natural gas as fuel are collectively called thermal power plants.

Thermal power plant: fuel is burned in the boiler and water is heated to produce steam at high temperature and high pressure. The steam reaches the steam turbine to push its blades to rotate. The turbine shaft drives the generator to rotate, the generator rotor winding generates a rotating magnetic field, and the stator winding cuts the magnetic lines of force to emit alternating current.
Nuclear power plant: The pro principleElectricity generation is not much different from that of a thermal power plant, except that the fuel used is different, which is nuclear fuel. The nuclear fuel in the nuclear reactor is used as the primary energy to heat water vapor, and the subsequent process is the same as that of thermal energy. Of course, there are many safety safeguards for nuclear power.
Hydroelectric power plant: Typically, a dam is built and a hydroelectric generator is installed in a factory building inside the dam. The pressure difference between upstream and downstream of the dam is used to convert the potential. The rotation also drives the generator to produce electricity (the latter principle is the same as thermal energy).
Pumped storage: this is also a hydroelectric power plant, but the difference with hydroelectric power plantsOrdinary hydroelectric plants is that ordinary hydroelectric plants produce electricity in one direction. In addition to generating electricity like regular hydropower, pumped storage can also be used. in the electricity grid The ability to “consume” and store electricity during off-peak periods. Pumped storage power plants typically have two adjacent dams, or two reservoirs relatively close to each other, and their water levels are quite different. They are called upper basin (high water level) and lower basin (low water level). Its hydraulic turbine is different from those used in ordinary hydroelectric power plants: it can generate electricity and can be reversed and used as a water pump. During electricity production, water flows from the upper basin to the lower basin. When storing energy, the turbine is used as a water pump,consuming the abundant electricity on the network and pumping water from the lower basin to the upper basin, which is equivalent. to transform electrical energy into water. The potential energy will be used to produce electricity in case of future need (peak network period).
