Using conventional transformer technology you you lose about 3%. What you step up = step down watts minus losses

BUT with RF type coils centrally fed Tesla style when you step up you increase the Joules Potential. High voltage has a lot of kinetic energy. Its here you have OU which is why Tesla always stepped up to HV. The HV electrostatic field energizes more ambient electrons whose energy is added to the system. In so doing it undergoes energy transformation from electron volts to magnetic of higher order. Revisit Newman motor for basics! inductance converts to high VARS as standing waves converts to high magnetic field strength provides motor TORQUE. Power increase far beyond what a pack of pp3 batteries provide only needs a few mA's.

Where OU exists as RE = RLC under RF simile.

On the way back down requires magnetic coupled transformers NOT parallel coils sharing the same flux path nor even RF as EM transverse coupling. This is what Don Smith was doing but it appears and even admitted critical circuit aspects were missing to protect investors. SO replicators deal with it  using conventional thinking and try to apply standard RF 1/4 wave principles to the coils = Crap results. Coupling needs to be magnetic only its 90 degrees off and backwards in all aspects of conventional theory.

   Guys:
   I had at one time thought the same thing about a step up, and the step down transformer, for more current.  Jeanna mentioned that she had tried it, and that she did not have much luck with it, as a bulb lit for a very short time, only.  There still may be a way though...
  Leds bulbs do like a certain amount of mA also to light all the way,  on not just voltage. I think there are Jtc that do output more current,  like my one inch toroid (shown) that uses a  76 - 76 turn primary,  only.
  The picture is of one of my Captret- Jtc that I'm working with now. Tonight it is lighting a dozen Leds so bright that I'll probably have to toss them in the trash like so many others that I've burnt out, due to the cap surges.  I'm still unable to locate any pots to control the voltage going to the bulbs.
  I've been  trying to find a balance point so that the batteries which are now several days old (and only dropped a volt) will keep up with the load without going down, down, well,  you know...   With one led its a lot easier to do, than when adding a dozen or more.

     What we need to work towards, is a joulethief that self runs completely !

     I have already started a small experiment on this and I managed to charge a cap up with a run battery,
     and got the cap up to just over 500 mV while only taking off about 10-15 mV from the run battery.

    I've also been able to swap mV back and forwards between the run battery and a supercap aswell.

    Also I would like to mention that in one experiment I did, I actually started charging up a supercap,
    from a run battery, and checking the cap and run battery with a DMM, and the run battery was actually
    going up in small amounts while the supercap was charging up!
   
    So we need a Joulethief that eventually runs itself.

     

@freepow
Thats a great result you have got woth the source battery and the cap increasing in voltage. How long di it manage to o that for?

Hey!

      I did it by using a rechargeable AA as run Battery powering the joulethief - which was lighting a LED dim, and at the same time charging a supercap 50F, then the supercap was feeding back to the run battery again, I'll have to try it again !
