The idea of a perpetual motion machine. Good imagination. However, according to the law of conservation of energy, under ideal conditions, 100% of the hydrogen and oxygen electrolyzed by the battery are given to the motor, and 100% of the electricity generated by the motor is used to charge the battery. can only be transferred in this way, and the motor has no excess energy.
Student, this hydrogen-based energy production is a type of thermal energy production. Thermal power generation refers to using the heat released from combustion to evaporate the liquid to form steam to rotate the turbine and then drive the generator. rotate to produce electricity. We are now Thermal power generation primarily burns coal, but the carbon dioxide produced by burning coal has a huge effect on the greenhouse effect. This is why we studys clean energy sources such as hydrogen that do not produce carbon dioxide. during combustion, as well as hydrogen batteries, new energy sources that use chemical reactions with hydrogen to produce electricity.
