Description: Perpetual motion machines — devices that can do work indefinitely without any external energy source — have captured many inventors' imaginations because they could totally transform our relationship with energy. There's just one problem: they don't work. Why not? Netta Schramm describes the pitfalls of perpetual motion machines. [Directed by TED-Ed, narrated by Addison Anderson].

Netta Schramm: Why don't perpetual motion machines ever work?

Why don't perpetual motion machines ever work?

Perpetual motion, an age-old intrigue, defies thermodynamics, aiming to create endless energy without an external source.

Inventive as they are, perpetual motion machines falter, unable to bypass the laws of physics that govern energy conservation.

While the quest for perpetual motion persists, it's our undying curiosity and pursuit of the unknown that truly never ceases.
