If you place two small LEDs across the 1k resistor as shown in the pic below,and a good 1.5v battery,both LEDs will light up when the JT is running.
This shows you that the L2 coil dose invert during the inductive kickback part of the cycle.

Hi Brad,

Thanks for answering my question. Yes, I was talking about L2 coil in your diagram.

As you showed that we can light LEDs with the inductive kickback effect in L2 coil also. But does that come at the cost of less power in the main LED (lit through L1 coil)? Or is it the extra energy available?
Or in other words can same energy be extracted through L2 coil also? (during inductive kickback of L1)

Yes it dose. The inductive energy is shared between L1 and L2--!BUT! you also reduce the waste heat energy being dissipated by the 1k ohm resistor.

So,you gain a little in way of converting available energy into light--but not much.

Hi you guys  :); can I just be a pain in the arse here and say I'm not sure all jewel thieves are the same,
I say this from experiments with Akula, and Ruslans Tesla Katcher coils, they are almost the same circuit.

Have a look on youtube 'Patric kelly' > perpetual light  clip  <   https://www.youtube.com/watch?v=Mf7aNQD2GPA

What I'm getting at is this, some generate a sine wave some an envelope and some a square wave.
if it's gain you want you need to make sure the transistor switches off a while in it's cycle in order to get the back EMF.

Happy days fellers

Hi Smoky,

Since last 2-3 days I have been studying about earth batteries, air batteries, water batteries, crystal cells, etc and I do not see any potential in lighting up the bulbs better than AA batteries. Let me know if I am wrong.

What I am looking for is a cheap solution (under 20$ and even less) to light bulbs in homes of poor people. I want to avoid solar panels and big batteries because the cost increases. Joule ringer seemed a good option. What I think is 10-15 minutes of human power would be capable of lighting bulbs for 3-4 hours.

It would be interesting if earth batteries were capable of doing that.


This is always a subject of interest for those who do not have access to an electrical grid.
As to date, the best solution I have found is a clockworks unit, used for baby grandfather clocks.
The small ones that sit on a table
You connect them to a pulley weight,mount it up high
 and attach a small D.C. Motor to the smaller gear in the back
30-seconds of winding can power a light source for a few days.


I'm sure someone could engineer a gearbox specifically for this but
clocks have already been through the commercial process, and
are mass produced.

Hi sm0ky2,

I am aware of Gravity Light Foundation that uses a similar concept of clock. But they are only able to produce light constantly for 20-30 minutes. That is the best run-time I am aware of.

And you mentioned that its possible to power a light source for a few days? Any experiments or sources that you are aware of and that you can share?

The mechanism sold for use in baby grandfather clocks works the best.
and the weight pulley controls run-time by length of pulley cable.


This is a controllable variable, that can be adjusted for any desired length
of runtime. Put it on a mountain, it can run for a month to light a tent in the
valley below.
Of course it may take you an hour to wind it up, it’s all relative.

The size of the motor/generator also affects things.

If you use the generator current to power a joule thief,
You can light more lights with it than direct drive.
