@ Artic_Knight

Putting capacitor across battery is always a good idea, but it will not have much effect unless there is an intermittent current drain that is higher than the battery is able to supply. The cap is able to store energy drawn from the battery at a current it is able to supply and then during short intervals supply current at a level higher than the battery could supply.

I believe I read somewhere perhaps on here that you can take a toroid and apply ac voltage to the primary coil and then wind a secondary on the toroid to power something else. And that if it worked the device would have no effect on the main device or draw anymore power then what is being used to power the main AC device.

I tested the idea and it works! Below are some pics form this mornings experiment. I have also started to add this to my fuji mod as well. My fuji circuit has around 230v AC and once I figure out how to add the concept to that I will post my schematics!

You could add a toroid with a pickup coil to any AC device and get energy from the magnetic filed I do not know if this is free energy but it is there and it shows no more draw with the toroid in place.

I am not sure who's idea this was or where I first read the plans but as soon as I find out I will give a link.

unfortunaly it does not work like you think.

a currents passing in a wire create a mag field that induce a currents in any near wires(or in a core).
that currents created by a mag field, if allowed to circulate, will create a mag field that will oppose the mag field creating that currents.

it mean : you can't have a free lunch this way.

it won't work, not because of Lenz's law.
Lenz's law is just an interpretation of phenomenas.
it is because this is how nature work.

if it was as simple as that, everyones would know it by now.
thinking all EE, electriciens, electronic repair mens, are idiots, or, they are all put to silence by "MIB" is mathematicaly impossible.

@all
study, then you will know how it work or can't work.
you will be able to focus more on ways to achive your goal this way.

sometimes a phenomena might do exactly what you want/need.

sometimes, you have to work around those phenomenas.
it won't help if you know nothing about them.

most of the time, unwanted phenomenas can not be worked around.
the only thing you might be able to do is trying to minimise them as much as possible.

a good example about minimising some unwanted phenomenas is the mk toroids designs.

wow, that's a heck of a conjecture... how in the world did you ever come to the conclusion that he was thinking this?
regardless, i'd love to see your math on that...

@TheNop,

I never said anyone was an idiot. I simply posted some results from one of my countless experiments. I am not sure why it works and welcome the chance to learn how it works.

As of now however I am pushing 100 volts, filling caps and lighting led's all from that simple mod of a lamp cord with a toroid.

Its very easy to reproduce the results I have posted and in doing so the experimenter will see and can easily prove that this type of setup draws no extra power form the source and yet there is a gain of power with the use of a pickup coil. I do not know why it works but it does work.

Thank you so much for your input it is most appreciated.

All the best,

additionally i found that adding a 10uf cap in parellel with the battery had no affect on the draw. this doesnt make sense as there should be additional draw from the supply unless the joule theif has become saturated to the max.

a cap in parallel do not allow AC or pulses to pass trough.
the battery provide DC currents not AC or pulsed DC.
why should it draw more or less currents ?
a cap is not a resistance.

the currents is limited in series connections tho.
the limitation is caused by the capacitance of the cap.
ex: a cap in series with a lamp will see the current passing trough them affected by the cap value.
the smaller the cap values, the less bright the lamp will be for a given frequency.

due to the chemical nature of batteries, a cap will assist, if placed in parallel to the battery.
it charge and discharge faster then a battery can.

i noticed a similiar behavior as to what you described with the cap. when i had it in parellel with a coil it smothed out the current however when i had it linking the 2 coils together it decreased current draw in the curcuit? how is that explained.

see above comment and example.
a cap can only be charge/discharge xx miliamps in a given time frame.
the time frame can be somewhat instantanious or set by frequency. ex: 60Hz or any RC, RLC constant.



@altrez
i was not saying you had sayed or implied that.
it was just a question to open eyes about the fact i wrote.
the forum crashed on me the first way i wrote it was in a question form.
sorry if i made it appear like you was saying that.

what you are doing work, yes.
what i say is your statement, "draws no extra power form the source ", is not true.
