Perpetual machine is a kind of so-called machine that can continuously move and do work without external input energy or only one heat source. Historically, people have been keen to develop various types of perpetual motion machines, including Da Vinci, Joule and other academic masters.
After the establishment of the thermodynamic system, the academic circles decided that the perpetual motion machine violated the hypothesis of the basic principles of thermodynamics and excluded it from the orthodox academic circles. However, the researchers of perpetual motion machine never stopped. From one side, we can also think that human enthusiasm for perpetual motion machine and various practices of manufacturing perpetual motion machine have promoted the establishment of thermal system and the progress of mechanical manufacturing technology.
1775 The French Academy of Sciences passed a resolution declaring that perpetual motion machines would never be accepted. At present, the United States Patent and Trademark Office prohibits the application for granting patent certificates to perpetual motion machines.
In 20 17, the existence of time crystal was confirmed, and its atomic motion was maintained without any external energy, which met the literal definition of "perpetual motion machine", but its energy could not be used until additional energy was added. If the entropy of the time crystal is not high enough, the crystal may be scattered into particles because the latter has a higher entropy, although it may take a long time.

Fang Huining drew his ideas on the drawings, measured them accurately and went to the steel market to find workers to make them in proportion. Fang Huining asked to import steel raw materials, and the cost alone was 10,000 yuan. For more than ten years, Fang Huining has made more than 200 "gravity cars" of different sizes. In order to store these "treasures", he rented a warehouse in the North Ring Wholesale Market, which costs a lot of money every year.
In order to raise money, Fang Huining sold her own property house and BMW. In life, Fang Huining is "idle" at home, but she is too busy to do housework. He immersed himself in his invention all day and all night. When he really can't help it, he smokes a lot to refresh himself. "When I am most tired, 1 hour can smoke a pack of cigarettes, and I will smoke one cigarette every night." Fang Huining said: "Many people don't understand why I live a good life and am not poor. I think it is worthwhile for my ideal. "
Fang Huining's son understands his father's insistence. He said that he would always support his father's invention. Fang Huining also proudly said that he did not leave any property to his son. Once my invention is successful, I will apply for a technology patent, hoping to give it to my son as a gift.
Fang Huining's friend Mr. Li told reporters that Fang Huining is very smart. Although his education is not high, he is a "genius" in physics. Nevertheless, Mr. Li is not optimistic that perpetual motion machine can apply for a patent.
On August 4th, the reporter interviewed Zhao, deputy director of the Science and Technology Department of Ningxia Patent Service Center. He said that he saw the "power car" made by Fang Huining. "I think it is actually a labor-saving deformation lever, a machine similar to a pulley block, rather than a device that can overcome resistance and transform a component into infinity. This doesn't make sense in physical principles and violates Newtonian mechanics. " Deputy Director Zhao pointed out that China's patent law clearly stipulates that patents that can be applied for must conform to creativity, novelty and practicality. Although Fang Huining's spirit is commendable, his "power car" does not meet the above requirements and cannot apply for a patent.
At the same time, experts believe that it is good to love inventions, but advocate inventors to spend the least money and produce the best results. Fang Huining's choice of direction is too profound. I suggest that he can proceed from reality and change his thinking.

China News Network-Men are obsessed with developing perpetual motion machines. 14 years, they sold the house, sold the car and devoted themselves to invention and creation.
