The principle that energy must equal heat plus work applies to electrical devices, such as generators, as well. You've heard of magnet motors, generators that produce more energy than it takes to run them, ad nauseum.
What fools a lot of people who should know better is that some of these gizmos actually appear to do exactly that — measurably put out more energy than they take in. As early as the year 1900 there were people who could take you into a room, hook a spinning bicycle wheel to a battery, and prove to you that the bicycle wheel was putting out more energy than the battery was producing.
The key word here is "appear." It was a scam then and it is a scam now.
Here’s how the scam works.
A typical generator has a rotating field of copper wires. This is called an armature. Move a copper wire through a magnetic field and electricity will travel through the copper wire. In a generator the mass of copper wire rotating around a shaft passes through magnetic fields inside the generator casing. Those magnetic fields are created by magnets fastened inside the generator casing. The magnets remain stationary, the copper moves.
In order to "demonstrate" the principle that an electric generator will put out more power than it takes in all you have to do is put the magnets to your armature where no one can see them—like inside the walls of the room your armature is operating in. What people think is the device being rotated is actually merely the armature of a generator that has a hidden magnetic field. The hidden magnetic field is then energized by incoming power from the Power Company or hidden batteries.
It’s as simple as that.
