The idea of ??"perpetual motion" originally originated in India.
The idea of ??a perpetual motion machine originated in India. Around 1200 AD, this idea spread from India to the Islamic world, and from here to the West. In Europe, the most famous early perpetual motion machine design was proposed by a Frenchman named Hennecaut in the 13th century. There is a rotating shaft in the center of the wheel, and 12 movable short rods are installed on the edge of the wheel. An iron ball is installed at one end of each short rod.
The designer of the scheme believes that the ball on the right is farther from the axis than the ball on the left. Therefore, the rotational torque generated by the ball on the right is greater than the rotational torque generated by the ball on the left. In this way, the wheel will rotate endlessly in the direction pointed by the arrow, and drive the machine to rotate. This design has been copied by many people in different forms, but it has never achieved non-stop rotation.
If you analyze it carefully, you will find that although the torque generated by each ball on the right is large, the number of balls is small, and the torque generated by each ball on the left is small, but the number of balls is large. Therefore, the wheel will not continue to rotate and perform external work, but will only swing a few times and then stop.

Negative of perpetual motion:
It is said that the concept of perpetual motion originated in India and was introduced to Europe in the 12th century AD. According to records, the earliest and most famous perpetual motion machine design in Europe was proposed by V. Hennecaut in France in the 13th century. Subsequently, people who researched and invented perpetual motion machines continued to emerge, although many scholars pointed out that perpetual motion machines were impossible.
During the Renaissance, Italian scholar Leonardo da Vinci spent a lot of energy studying perpetual motion machines, and finally came to the conclusion that perpetual motion machines could not be manufactured. At the same time, J. Cardin (famous for being the first to provide the roots for solving cubic equations) also believed that perpetual motion machines were impossible. The first type of perpetual motion machine violates the law of conservation of energy, while the second type of perpetual motion machine violates the second law of thermodynamics.
With the realization of the impossibility of perpetual motion machines, the patent offices of some countries decided not to accept patent applications for the invention of perpetual motion machines.
