With the further restrictions on automobile emissions and the continuous rise of oil prices, new energy vehicles have developed rapidly in recent two years. Nowadays, all the new energy vehicles on the market are electric vehicles, and there are not a few hydrogen energy vehicles. However, a 55-year-old uncle in Fuyang, Anhui claimed that he invented a magnetic cycle car by other means, which can drive without refueling or charging. He also said that he hadn't recharged for half a year.
Uncle Anhui invented a car without charging or burning oil and applied for a patent. Netizens laughed after reading it. How did this happen? Wang Xuecai is an ordinary farmer who graduated from primary school, but he likes studying electricity since he was a child. I have also been trained in the local electronic school and learned some physics knowledge about electricity. Later, he spent 40,000 yuan to buy an electric car, and then found that it was troublesome to charge it every time, and it took five hours to fully charge it. So he thought of installing a gear on the driving shaft of the car, and then installing a generator next to the gear to charge the battery of the car. The generator is connected with two groups of batteries. When the car is running, the gear moves to drive the generator to charge the batteries. When one group of batteries is fully charged, it will automatically switch to the next group. Wang Xuecai, a farmer in Fuyang, applied for a national patent for his "automatic charging device for electric vehicles" and set up his own technology company to study this kind of magnetic cycling electric vehicles.
Wang Xuecai, the "automatic charging device for electric vehicles", can really charge once, but not for one year, but it can't move forever. In fact, the magnetic bicycle invented by Wang Xuecai has been studied for a long time, but it is not feasible in the end. We all know that energy will be lost in transformation. Although this method of charging the battery by the generator does not violate the law of conservation of energy, it cannot be realized because it violates the second law of thermodynamics.
Simply put, when driving the motor, the electric energy of the motor will be less and less, and the wires have resistance, so heating will consume energy; The generator has friction, which will consume energy; In fact, they did nothing. They just transfer energy to each other. Every time they transfer energy, the kinetic energy of the motor will be less and less when driving the generator, and finally stop. Moreover, with the consumption of energy, the power of cars will be lower and lower.
Therefore, this so-called "perpetual motion vehicle" without charging or refueling is not feasible, and putting a generator and two batteries in the trunk will not only increase the weight of the vehicle, but also be very dangerous. These perpetual motion machines are either completely wrong in theory, and even if they are built, they will not move forever. This idea of energy conservation and environmental protection by folk scientists is ok, but it still needs knowledge as the backing in practice.
