Wow man, that is a great article!  Who knows where this might lead?  Thanks for posting this.

That sounds interesting.  If you use supercaps though, I don't think you need the buffering.  I can run a Bedini motor off of nothing but a single supercap.  It will run for a very long time.  Now, you are working on a 12 volt system and I don't know of any supercaps made for that voltage.  Mine are all either 2.3 or 2.7 volts.  Perhaps you could use several in series to get 12 volts?  I don't really know.

I hope  you are right ......and  a super cap will run  a JT  .
Personally  I  don't think  it will  work .
A Bedini is  a completely   different  animal.
The  self charging  circuits seem to be based on resonance .....  they  are completely dependent  on being  balanced .   
Once something  changes that balance  the self charging state  vanishes .

Here is a video of me running a Bedini off of a supercap:

The supercap was charged via my EER (earth battery) but this circuit is the self charging Bedini as modified by Jonny Davro.  The cool thing about his design is that you can run many many satellite rotors from the same coil and you can place pick-up coils near each rotor for additional output beyond the back emf from the bifilar coil.  Check Jonny's topic here and some of his videos, it is wild.

In this video, I am charging a 9 volt battery from the 2.7 volt supercap (650 Farad) with the standard Bedini circuit.

Sorry ......my connection  is  to slow to watch  videos

I  have finally  got my 12 V system  going
It  has  been  running  my 90 LED array for several hours ......   
The TIP2055   is running cool ...... barely  warm to the touch .  That is what I wanted.

Looks like  I am close to self  charging .

With a large battery it is  difficult  to tell for sure  if  it is actually charging or  just  recycling some of  its energy . 
I guess only time will tell

I have  been playing  with my  12 V  circuit.
It is like a coompletely  different animal compared to the  1.5 V circuit .
Some of my coils  I have not  been able to get to work at all .
Some  of them work  but not as well as with  1.5V.
My bi-metal  primary works  much  better  with 12V ......but  it  gets pretty  warm .

I have been using  the TIP3055 .  It is not quite as  powerful  as  the 2N3055 but  I think it is  quite a bit tougher .   The way I have  my  charger set up ......if I  turn off the switch on my battery  but forget to unplug the charger ....I  will have about 108V 
Yesterday  I made the mistake of connecting  the  board  when the  battery was  off .    I saw  a spark ..... and realized  what I did .   My TIP2033 is still  OK.     One  spark  was all it took to kill my 2n3055 before .


I  have to order more toroids before  I can  explore  some of the  ideas  I have  for the 12 V  circuit .



Is anyone   expermenting   with feedback ?
I  was  using  a  flyback  transformer  as a feedback  coil .
I  hooked  the output of  my secondary  through the HV  coil  of the flyback transformer .
I found  that  5 of the  terminals  on the  bottom  were useful for feecback ....  one of them  was  high  enough  voltage to  light up another  LED array.
