The Johnson Perpetual Motor
Perpetual motion machine
Perpetual motion machines have been the “holy grail” of engineering for centuries. Various scientists, engineers, and other less-scrupulous inventors have claimed to have invented machines that produce energy with no input. These have historically been proven to be fraudulent, with hidden a power source. The Johnson perpetual motor, patented in 1979, is a motor powered by magnetism. Machines are intended to perform useful work, the laws of thermodynamics limit the amount of useful work any machine can deliver without the addition of energy. Energy can never be created or destroyed, it can only be transformed from one state to another. This concept is the basis for the term “over unity”, used to describe perpetual motion. Any machine cannot produce more energy than it consumes. The machine may operate for an extended period, but the laws of thermodynamics prevent the machine from perpetually turning, due to energy loss from friction.
Howard R. Johnson patented a permanent magnetic motor, which used a rotor and stator powered by magnets. The device is a magnet-powered electrical generator, which uses the attractive and repulsive forces inherent in magnets to turn the motor. The device consists of a wheel or rotor with magnets attached to the outer surface, with magnets placed radially around the circumference of the rotor on a drum which in turn rotates. The drum then turns a conventional electrical generator via a belt and pulley. Potential energy in the magnets is transformed into kinetic energy in the rotation of the rotor and drum. The kinetic energy is then transformed into electrical energy by the attached electrical generator. The successive attraction and repulsion of the magnets provides an inertial rotation, which could continue for an extended period, until the energy loss due to friction in the rotor’s bearing surfaces slowed and eventually stopped the machine. This fact would technically make the Johnson perpetual motor not a perpetual motion machine, but it would be, for practical purposes, an extremely efficient machine capable of transforming energy with very little lost.
The Johnson perpetual motor was billed by Johnson as a “free” electrical generator, and the motor has the potential for power generation at a limited cost. The machine ‘s power output would be limited by the size of the motor, and size and thus the power of the magnets. The energy loss due to demagnetization was estimated by Johnson to be less than 2 percent over an operating period of 18 years, while the device could power a 5,000 watt generator, and produce 10-12 Horsepower. This power output would be large enough to power the average household, provided storage batteries were also installed. Green energy initiatives have focused in harnessing wind, geothermal, and solar energy, and while these are important energy sources that should be further developed, they are significantly more inefficient than the Johnson perpetual motor. The Johnson perpetual motor may not meet the strict definition for “over unity” or perpetual motion, but the device could come close to it, albeit limited to small-scale applications.
