Okay, here is my first real set of comments, from the following posting on the EF thread:
http://www.energeticforum.com/renewable-energy/6932-3-pole-kit-rennaissance-meeting.html#post120884I am going to paste the entire posting here,
and then make my comments in red text.

As promised here are my work in progress notes minus my plans going forward which we can all discuss, please feel free to correct me if I have things wrong or at least have a discussion around it.
Concept
The Bedini motor harnesses extra energy from the environment by the use of the radient voltage spike coming from the colapsing magnetic field in a coil of wire. This spike charges a battery that makes use of this pure voltage spike to chemically recharge itself. The extra radient energy is gained due to a disturbance in the surrounding environment that allows the extra energy around the wire (heaviside flow) to enter the circuit.
It doesn't "harness extra energy from the environment." I have mentioned this two-faced business with respect to how the Bedini management people discuss their proposition before. When pushed, they will say a Bedini motor is NOT a free energy device, but they seem to be more than happy to let their followers believe that it is a free energy device. We will see if John Koorn or someone else comments on this to correct this false impression. As we know, the "radiant" voltage spikes are NOT "radiant energy" they are spikes of current from the discharging coil, and all of the energy in those current spikes came from the source battery and nowhere else. It is not a "pure voltage spike." Letting that false concept be propagated is one of the worst transgressions of the "Bedini management group." The battery does not "recharge itself." it gets charged from the current spikes. The whole business about "extra radiant energy is gained due to a disturbance in the surrounding environment" is complete and utter nonsense.
Now that was one serious rebut! Right here you can see almost all of the false concepts in one basket. So the real question to ask yourselves is who is providing the disinformation and who is providing the truth?The energy lost from the primary battery is due to the energizing of the 3 coils briefly which requires energy to establish the magnetic field and provides rotor push via repulsion of north poles. The use of permanent magnets in the rotor provides a free magnetic field used to trigger the coil pulses and also to provide repulsion moving the rotor. The speed of the motor is self determined by the applied voltage (field strength) and the number of asymetrical trigger poles. The rotor torque is determined by the number of pulse coils, more coils equals more torque. If using a generator coil to drive a load then it will affect speed depending on the current load (BEMF).
With respect to the speed of the motor, the better way of explaining that is that the power put into the rotor from the magnetic repulsion is counterbalanced and nullified by the power being lost due to bearing and air friction. Note also that when the rotor it turning at its steady-state speed and the supplied power is in balance with the bearing and air friction power, the available rotor torque to do useful work is zero. Only when you put a real external mechanical load on the rotor and it slows down, are you getting usable rotor torque.
For this statement, "If using a generator coil to drive a load then it will affect speed depending on the current load (BEMF)," it's not really "back-EMF," the generator coil would cause Lenz Law drag because it's driving a load and current is flowing through the coil.The COP>1 has to be acheived by:
COP = Pout / Pin
Pout factors:
Increased charge in charge battery (after rest period)
Rotary mechanical force that can be sustained
<-- Remember if you don't put an external mechanical load this is zero.Excess Generated electricity (Gen coil etc...)
Pin factors:
Primary Battery consumption (after rest period)
<-- "after rest period" is the clue telling you that they are using battery voltage as a reference and that's dead wrong!Read the following posting from the "Bedini SSG measurements" thread to learn why you cannot use battery voltages for your COP measurements:http://www.overunityresearch.com/index.php?topic=364.msg7093#msg7093Therefore:
COP = (Increase in charge + Mechanical force + Generated power) / Primary Battery consumption
The 3 pole kit performance goals
- Should be in the neighbourhood of 5000RPM
- Should generate about 24V
- Should be able to put all the energy into charging the batteries
- Should be able to become a self runner
<-- GOOD LUCK Mother Nature is watching you!- Should be able to indefinetly run using a basic battery swapper system to rotate 3 or 4 batteries
<-- The proof is in the pudding and I don't think anybody has tasted that pudding yet!The SSG diagram and description of the circuit operation
(SEE ATTACHMENT FOR MY REVISED SCHEMATIC)
- As the magnet on the rotor approaches T1 it induces a current in the trigger side coil (left)that goes through D1, R2 and the potentiometer R1. It does not induce into the drive side (right) because it is an open circuit. When the Magnet is directly above the core the induced current stops.
- When the magnet has past the core it induces a current in the opposite direction (Lenz’s law) that flows through the base of the transistor Q1 and out through the emmiter. This turns on Q1 and then current flows from BT2 into the drive side coil (right) repulsing the rotor magnet by creating a like (N) pole.
- Once the magnet is past the the trigger coil the induced current stops and shuts off Q1. The collapsing magnetic field then sends a spike through D2 and into BT1 charging it.
- The Neon bulb NE-2 is for visual feedback and provides dampening of too large of spikes due to its high resistance, and if there is no charge battery connected protects the circuit.
<--- Correction, the neon bulb turns on above a certain voltage threshold and then clamps the voltage at that threshold which protects the transistor. It does not have a "high resistance," in fact once it switches on it acts like a "negative differential resistor."- Purpose of LP1 must be to stop the reverse current flow and give a visual confirming that you have trigger voltage
- For the 3 pole kit to make it run LP1, R1 and R2 are replaced with the 220ohm resistor and you add the 3 identical circuits in paralell to eachother at the 4 common points (BT2 negative, trigger coil start, BT1 positive, and either the switch terminal or junction of BT1 negative and BT2 positive)
Troubleshooting tips with the Energizer
- Initial problem might occur due to the trigger circuit and the Vbe not being high enough. Factors to consider are moving the core closer to the rotor to induce more voltage in the winding, and also adjusting the resistance to a lower value in the trigger circuit which should allow more votage to the Vbe jucttion
- Once able to prove that the transistors are turning on (should see the rotor coast to a stop rather than sudden stop) you need to adjust the timing by moving the trigger coil to a spot where the pulses are pushing the rotor more, typically it seems to be off dead center by 10degrees and depends on the direction of rotation
- To prove each coil is firing, remove the wire from one coil at a time. If it slows down then that coil was firing, otherwise it might not have been working and requires using an oscilliscope or voltmeter
- Upon hookup of the battery there can be a slight inrush current in the coils. This might be enough to induce a current in the trigger circuit and actually turn the transistor on to fire it. Try starting with the pots on maximum for the hookup and then crank them down for the start to limit the current to the base
