The Perpetual-motion Machine: Looking Inside

Claims to produce more energy than it consumes, violating the First Law of Thermodynamics (Conservation of Energy).

The phrase "Looking Inside the Perpetual-Motion Machine" generally refers to examining the history, scientific impossibility, and internal "tricks" of devices that claim to run forever without an external energy source. Core Concept: What is a Perpetual-Motion Machine? Looking Inside the Perpetual-Motion Machine

To "look inside" these machines, scientists categorize them by which physical law they attempt to break: Claims to produce more energy than it consumes,

Attempts to convert thermal energy into work with 100% efficiency without a "cold reservoir," violating the Second Law of Thermodynamics (Entropy). Looking Inside the Perpetual-Motion Machine
