Modify circuit to dump radiant back into input
Oct. 20, 2004
Having designed various chargers and cyclers for various battery types, I would say they are using deltaV/deltaT or a discharge slope verses time under a known load. Although the data sheet says very little, they are very specific in that it must be a 12 volt (6 cell) lead acid battery. They also don't say, but I'll assume you can select ranges of AH capacity and by using an internal lookup table in software, accuracy should be reasonably good.
However, good enough to prove John Bedini's radiant battery charging circuits are working is another question! IMHO, a simple modification to his circuits, whether it be the solid state or moving PM version, would be to add another switch to the top or positive end of the main coil which would be turned on and off synchronously with the lower switch. An additional diode would also be required. Basically, this configuration would allow the main coil to dump radiant and/or stored energy back into the battery that is powering the circuit. IOW, the battery should recharge itself from the excess radiant energy!!! This would conclusively demonstrate the theory is working correctly. Perhaps John or others who are attempting replication could give this a try without too much difficulty.

Can't be closed loop
John and Peter have tried this (or something analogous), and it does not work. Input needs to be separate from output.

the only way to measure the charge state of a lead-acid battery is.....

Hi,
Surely the only way to measure the charge state of a lead-acid battery is using the specific gravity of the electrolyte. The battery should be discharged to a measured specific gravity and recharged to a another defined value at a specific temperature. SG is very temperature sensitive. Forget voltage it means nothing. Also all the cells in the battery are not necessarily the same. Shortly after application of a load the battery voltage briefly dips before rising again. For example typically, with a constant moderate load, starting initially at 2.2 volts per cell the battery voltage will fall to about 1.85 volts then rise shortly after to 2.05 volts and then it gradually declines in a non-linear way to about 1.75 volts. Specific gravity indicates the true chemical state of the cell at the moment of measurement and as such should be independent of the method of charging.

supercaps for Bedini motors
From: "Stefan Hartmann" <harti@harti.com> Date: Thu Oct 21, 2004 8:10 am Subject: supercaps for Bedini motors

These supercaps could be tested for Bedini motors.
As they also have alufoil and graphite in there and store energy on a chemical process like in an electrolysis cell, where produced oxgen is stored inside the graphite mesh.
These could be tested for the Bedini motors to have an easier energy out versus energy in efficiency measurement.
They don´t break down like lead acid batteries, when you discharge them totally ! So the driver supercap for the Bedini motor could be charged to 12 Volts DC ( use 6 supercaps in series for this) Then you know the energy you put in there via Energy= 0.5 x C x V^2.
Then the charge supercap will be charged by the coil while the drive supercap is slowly discharging.
Then see, how long the drive cap will work until it is discharged. Stop the motor and then immediately measure the voltage of the charge cap and calculate its energy again via: Energy= 0.5 x C x V^2.
Now compare both energies and you will see, if the Bedini motor really is overunity.

Back Emf/Radiant Energy
Hi all,
JB says he is not using back emf, but voltage spikes.
Howvever, it appears that he may be getting his voltage spikes from inductive kickback, which is similar to back emf.
He basically describes radiant energy as voltage without current.
If this is true, a battery could be made to self-charge by correctly pulsing the terminals with the proper voltage waveforms (timing extremely important), while not allowing any current to flow (except what is necessary for switching).
This idea would simlify the cricuits necessary to get the Bedini effects, without having any load at all.It would also increase the efficiency of the effect.
Also, it appears that JB is getting the 2nd battery to charge by causing an internal flow of electrons from positive to negative, with little or no external current. This might be induced by short negative going voltage pulses applied to the positive terminal.
