Most perpetual machines try to use force from magnets. Gravity is also a popular agent of action. Other machines depend on buoyancy (like the one in the video below) or gas expansion and condensation.

In a lab in Scottsdale, Ariz., IEC is preparing a magnetic generator for commercial use and is using this ‘Crystal device’ to demonstrate how its theories work.

A permanent magnet motor would not produce energy and would not be a perpetual motion machine. Instead, it would simply use the electromagnetic energy delivered by the angular momentum of the ...
