Simple Magnetic Overunity Toy
Appearance
The Simple Magnetic Overunity Toy was a device by Greg Watson in 1985 that he claimed was a perpetual motion machine. These claims have been shown to be false.
In the design, a steel ball is pulled up a ramp by an array of permanent magnets. At the top of the ramp it falls, converting magnetic attraction into kinetic energy. Perpetual motion (overunity) has not been achieved with a SMOT. While it has been demonstrated that the ball can be cycled from the starting point of one SMOT to the starting point of a second SMOT (and third and fourth)[1].
