Sterling D. Allan's Replication of John Bedini's Simplified 'School Girl' Motor-Energizer
Replication accomplished on Oct. 9, 2004. It was the first one built based on the plans presented here. Experiments were run, and data were collected for about three intense months. Others have taken the experimentation further with their replications.
- At the time, I did not have a way to quantitize the mechanical energy of the wheel spinning, so I did not have a way to document the net energy "in" versus the net energy "out". Others, including Rick Friedrich and Peter Lindemann, who have experimented with this system and taken such measurements claim that there is more energy on the output side, than on the input side -- that this system is indeed invisibly extracting energy from the environment somehow. (SDA; July 31, 2007)
- List of Experiments ran and data obtained by Sterling Allan, using this set-up.
- Video of Perendev Magnet Motor and Bedini Motor replication - "I don't like the term perpetual-motion", says Sterling D. Allan. Whatever you might call it, the Perendev & Bedini Motors that Sterling brought to TeslaTech 2005 certainly caused a stir. (American AntiGravity; Jan. 12, 2006) [video]
- The output batteries charge at approximately the same rate at which the input batteries discharge. I have charged Lead Acid, NiCd, and NiMH batteries. I have noted that the Bedini SG-charged batteries last longer than when charged by some other means. I'm in process of documenting the difference (not high priority, as other phenomenon have my interest).
- I have achieved rotation speeds of from ~25 rpm to ~370 rpm (22" diam wheel). The rough estimate of energy required to maintain the wheel's rotation at 60 rpm is in the range of ~0.08 Watts.
- Solid State Resonance Discovery
- On Oct. 19, in Experiment 5.2, I accidentally discovered a way for the circuit to run in solid state resonance, with no rotation of the wheel required. I have subsequently documented the relationship between ohms and amps and state of charge.
- Balancing the Egg
- On Dec. 29 I discovered a narrow rotation speed of 54.8 and 55.2 +/- 0.05 rpm at around 2.66 ohms base resistance (with 16.5" diam wheel having 24 magnets) in which a solid state resonance that occurs from 0 to 55.3 rpm "fights" with two stable rotation resonances that begin to come into play from 54.8 rpm an up. From 55.0 rpm and down, the wheel decelerates to zero if left alone. From 55.1 and up, the wheel accelerates to the first stable rotation speed of 97.5 rpm where it maintains indefinitely. If given a manual spin faster, the second stable rotation speed is 191.3 rpm. In that narrow rotation speed window of 54.8 and 55.2 +/- 0.05 rpm, which is very hard to get to, a delicate balance point can be maintained like balancing an egg on end. It got it to last for as long as 15 minutes without any outside assist. Once it starts going one way or the other, it does so rapidly. What is astonishing is that at the balance point, the input and output amps measured (ahmmeter in series) jump all over the place, not sinusoidally, but randomly.

Sept - Dec 2004
Wheel was 22" inch diam. rear mountain bike tire (non-metalic rim) lined with 16 ceramic 5 magnets per spec.
My coil had ~425 windings of #20 and #22 magnet wire.
Dec 2004 - present
I am using a 16.5" inch diam. front bike tire (non-metalic rim) lined with 24 ceramic 5 magnets per spec.
My coil has ~1095 windings of #19 magnet wire (bifiar winding).
- Video with audio explanation (1 Mb avi) - shows motor running, general layout.
- Video showing the ringing effect (1.1Mb avi format) - Taken Oct. 17, aroung 11:55 pm mdt -- before I realized this was a solid state resonant effect.
As of Dec. 24, 2004 my wheel is 16.5" diameter and has 24 magnets equally spaced around it.
Close-up of coil, with 1,290 turns of 19 gauge magnet wire. Integrated to my replication as of Dec. 28, 2004.
