Computer fan battery charger

[nimrod]

I have replicated Imothep bedini circuit with 80 mm computer fan and it works.
I almost damaged the fan as nobody has explained how to isolate the circuitry
from the coil windings. Can some kind soul show me an easy way to access the coil
wires without risk of damaging the fan?
The beautiful thing about this battery charger is that it
can charge ordinary "aaa',  "aa" , "D'"  and 9 volt batteries without risk of explosion.
Ordinary battery charges works only on rechargeable batteries. This charger has an
input of 12volts but generates a flyback voltage in excess of 30 volts.
Because it is pulsating no heat is generated  even after 24 hours.
I can refer you to the website that explains how all this is possible. The parts for
this devise can be salvaged from a discarded tower power supply.
We can help to save the environment if more members use this charger.
If you have tried building this charger and have problems I can help to get it running.
