This model represents some examples of **perpetual motion machines**, which are hypothetical devices designed to do work indefinitely without an energy source. According to the laws of thermodynamics, such a machine is impossible to create. Despite this, the concept has intrigued people for centuries, and many have attempted to design such machines. We introduce four types of perpetuum mobile, although there are numerous other proposals. Perpetual motion machines can be classified according to the specific law of thermodynamics they purport to violate. Our models focus on perpetual motion machines of the first kind, which claim to produce work without any input of energy, thus violating the first law of thermodynamics, also known as the law of conservation of energy.
