A perpetuum mobile was (and still is) an apparatus that baffles and intrigues many by its mechanics. However, some scientists and programs, such as the Royal Academy of Science back in 1775, have rejected the machine because it defies the law of thermodynamics that energy cannot be created or destroyed. The perpetuum functions in such a way that work is applied to the machine without using an external force, which on paper makes it seem impossible to occur. Around that time, many scientists were creating their own proposals and versions that utilized the mechanics of the perpetual motion machine, which may have also played a role in the Royal Academy's rejection of the projects as well. Overall, the machine was thought to not be possible due to the lack of external force according to the first law, but to this day inventors continue to study and brainstorm new designs that utilize this machine's mechanics.
