A selection of perpetual motion machines

The perpetual motion machine (lat. Perpetuum Mobile) - an imaginary device that allows you to get useful work more than the amount of energy communicated to him.

Attempts to study the place, time and causes of the idea of ​​the perpetual motion machine is a very difficult task. It is no less difficult to name the first author of such a plan. The earliest information about Perpetuum mobile is, apparently, the mention that we find in the Indian poet, mathematician and astronomer Bhaskara, as well as individual notes in the Arabic manuscripts of the XVI century., Stored in Leiden, Gotha and Oxford [1]. Currently, India is rightfully considered the ancestral home of the first perpetual motion machines. So, Bhaskara in his poem, dated about 1150, describes a certain wheel with obliquely attached along the rim long, narrow vessels half filled with mercury. The principle of operation of this first mechanical perpetuum mobile was based on the difference in the moments of gravity created by the fluid moving in the vessels placed on the circumference of the wheel. Bhaskara justifies the rotation of the wheel very simply: “A wheel so filled with liquid, being mounted on an axis lying on two fixed supports, rotates continuously by itself.” The first projects of the perpetual motion machine in Europe belong to the era of the development of mechanics, approximately to the XIII century. By the sixteenth and seventeenth centuries, the idea of ​​perpetual motion was especially widespread. At this time, the number of perpetual motion projects submitted to the patent offices of European countries grew rapidly. Among the drawings of Leonardo Da Vinci, an engraving with a drawing of a perpetual motion machine was found.
