Hi all!
As far as I understood there is still no answer to the main question: can be the COP of the Bedini fan more than 1, i.e. can we get from it more energy than taken from the battery.
The obtained energy consists of mechanical job of the fan, charging battery and heat. Why the main (or the only) way of utilizing electricity was chosen to charge another battery?
As it was written, it was not possible to measure the amount of obtained energy, because it's possible to measure volts, but not amps. But if one simply connects a resistor instead of a battery, it would be possible to measure joules and watts, by calorimetric method, measuring the amount of heat obtained. Then it's possible to measure COP, isn't it?
To minimize losses in mechanical job of the fan and to get more into electricity, the blades of the fan can be removed, has anybody tried it?

for most people the COP of the bedini fan is greater than 1 because we have a fan with its mechanical output and charging battery charging close to 100% efficiency. If we had an effective generator connected to the motor we could easily measure this.

The strange form of electricity that is used to charge the battery can also be used to power fluorescent lights etc.

I believe if we tried to use the method you suggest to measure output we would be disappointed in the results. The over unity is happening in the way the battery is being charged and not in the fan.

I have removed the fan blades to try and see if i get any sort of improvement and to be truthful there was no improvement at all. we have to convert the mechanical power into electricity using conventional methods

Ok, if removing the blades doesn't cause any change, it would be interesting if, on the contrary, some extra mechanical load would be connected to the motor - will it cause less charge of the battery and if yes, how much loss. Of course, the most interesting is the case if we could measure the work of the motor: attach a known measured friction, or make it lift some weight by winding a thread; or perhaps there are some generators which enable measuring mechanical work spent for their rotation. If we measure the work, we can estimate if the COP is greater than 1.

On the other hand, concerning the battery:

You believe, and is this belief well-grounded? Is it not worth experimental checking?
And the next thing, if you're sure that the amount of electicity brought to the battery is not so large and the effect derives from in the shape of signal and, therefore, way of charging, then it should be possible to build an electric converter generating a pulsing voltage similar to the one obtained from Bedini motor and to use it for charging batteries with an explicit COP>1? In this case we don't waste power for working motor and get energy "from nothing", from this extra efficient way of charging batteries?

PS If it were possible I would try to build and to check everything by myself without asking questions, but unfortunately now I don't have time for it, perhaps it is interesting to someone else who has more possibilities and/or knows more to answer these questions.

If you look at the output of a bedini fan on a scope you will see it pulses many times each time the magnet pole passes the coil. if the motor speed is high then it only pulses once or a few times. The number of pulses per second remains the same so there is no gain in speeding up the fan.

When we use the torque output of the fan we find the output weak. to make it stronger we have to increase the current input by increasing the duration of the pulse. when we do this we loose efficiency when it comes to charging the output battery.

Increasing the voltage and keeping the pulse short keeps the efficiency of the charge the same but does increase the mechanical output.

You can tell when the fan is at its optimum charging efficiency by listening to the noise the coils are making. the louder the noise, the more efficient the charge is a good rule of thumb.

With the size of a bedini fan we are only talking a few watts of mechanical power and it is difficult to measure this so size does matter.

Your suggested method for measuring mechanical output was the best i could do and i could not get reliable results even though it was obvious to me that i did have a cop greater than one.

Now i am working on bigger motors.

When we measure the Electrical output of the fan and compare it to the charge put in the battery it does not make any sense. For example I was getting 100+volts at a few milliamps and after 10 hours my 12 Ah battery was fully charged. It should have taken much longer on that output. It is well documented that amps cannot be measured with radiant energy so I believe any amps that i was getting was just because of a transformer effect in the coils and not the output of radiant energy. I was getting energy from somewhere because the battery was fully charged and i could prove that by load testing it.

All my experiments with building radiant chargers has resulted in a very efficient charge rate but no over unity, but with a motor we do seem to have it. Its about collecting and converting the magnetic energy into the coils into usable power and a motor does just that.

Please read the new topic i am posting on multi fillar windings I think your answer is there I have not built it yet so you may beat me to it hehe. I don't have a problem with that because John Bedini has already done it and i think this is a lot to do with the over unity he has achieved.
