Just like living things, all machines require energy to do work. While organisms get energy from the food they eat, machines obtain it from sources such as fuel. As more machines are invented to perform more complex tasks, they must also be sustained by enough energy supply. For this reason, scientists consider the possibility of creating a perpetual motion machine that makes and does not use up energy.
A perpetual motion machine is a device that can run indefinitely without the need for an external source of energy to power it. It is designed to reinvest in itself the energy it produces to keep moving. Once it starts, it runs forever while providing free energy.
The perpetual motion machine is an inventor's dream. If anyone figures out how to make it work, we can get something for nothing, which means we can generate energy without spending any energy.
