Legal Matters Relevant to John Bedini's "School Girl Radiant Energy Circuit and Motor"



For nearly fourteen years, John Bedini has been publicly posting the plans for many of his circuits and motors, encouraging others to duplicate his findings. The plans being present here are essentially the same as those that have been posted by John for years. The most public page most related to project site is


John Bedini and Peter Lindemann are aware of this project and have given their general approval of this pursuit. They are busy with other tasks and do not have time to manage this project to assure the accuracy of the plans or of the explanations. While this project has their blessing, it should not be construed as something they have reviewed and confirmed in all its details.


While John Bedini is generous to encourage people seek to replicate his discoveries for scientific research, he does hold legal right that any market applications be licensed through him, which at present is represented by Bedini Technologies Inc. He holds several patents that cover these circuits. In any foreign countries where a patent may not have yet been procured, we request that you do the honorable thing, and work through John Bedini.

Relevant Patents by John Bedini

School Girl Circuit and Motor

This is the patent for what has been called the "school girl," after a 10-year old who replicated it for a science fair. The present project ([OS:Bedini SG|School Girl (Simplified)]) is a simplified version of this patent. The simplified version has no armature, no pulley for the armature firing mechanism, only two windings on the coil, and the four-way bridge rectifier is replaced by a single 1000V diode.


Abstract of US2003127928 
"A back EMF monopole motor and method using a rotor containing magnets all of the same polarity and in a monopole condition when in momentary apposition with a magnetized pole piece of a stator having the same polarity, said stator comprised of a coil with three windings: a power-coil winding, a trigger-coil winding, and a recovery-coil winding. The back EMF energy is rectified using a high voltage bridge, which transfers the back EMF energy to a high voltage capacitor for storage in a recovery battery. The stored energy can then be discharged across the recovery battery through the means of a contact rotor switch for further storage"

Permanent electromagnetic motor generator

This is the underlying principle.

Other Tangential Patents by John Bedini

These represent advanced manifestations of this basic design being presented here in this "[OS:Bedini SG|School Girl (Simplified)]" project.

Self Actuating (?)

{If I recall correctly} Doesn't have to be kick-started, but begins turning as soon as switch is activated.


Abstract of correspondent
US6392370 : "This invention is a back EMF permanent electromagnetic motor generator and method using a regauging process for capturing available electromagnetic energy in the system. The device is comprised of a rotor with magnets of the same polarity; a timing wheel in apposition to a magnetic Hall Effect pickup switch semiconductor; and a stator comprised of two bars connected by a permanent magnet with magnetized pole pieces at one end of each bar. There are input and output coils created by wrapping each bar with a conducting material such as copper wire. Energy from the output coils is transferred to a recovery rectifier or diode. The magnets of the rotor, which is located on a shaft along with the timing wheel, are in apposition to the magnetized pole pieces of the two bars. The invention works through a process of regauging, that is, the flux fields created by the coils is collapsed because of a reversal of the magnetic field in the magnetized pole pieces thus allowing the capture of available back EMP energy. Additional available energy may be captured and used to re-energize the battery, and/or sent in another direction to be used as work. As an alternative, the available back EMF energy may be dissipated into the system."

Solid State

No moving parts.

A two-phase solid-state battery charger can receive input energy from a variety of sources including AC current, a battery, a DC generator, a DC-to-DC inverter, solar cells or any other compatible source of input energy. Phase I is the charge phase and phase II the discharge phase wherein a signal or current passes through a dual timing switch that controls independently two channels dividing the two phases. The dual timing switch is controlled by a logic chip or pulse width modulator. A potential charge is allowed to build up in a capacitor bank, the capacitor bank is then disconnected from the energy input source and then pulse charged at high voltage into the battery to receive the charge. The momentary disconnection of the capacitor from the input energy source allows for a free-floating potential charge in the capacitor. Once the capacitor has completed discharging the potential charge into the battery, the capacitor disconnects from the battery and re-connects to the energy source thus completing the two-phase cycle.

Dr. Lindemann plays an integral part in explaining how radiant energy works. The following video and book (essentially transcribed from the video) is a must for anyone pursuing this technology.
