Heating water using joule Thief?

Thanks sm0ky2 for the info.. I've been playing with jt's for a while.. and I have never come across an explanation as thorough as yours. . To explain the relationship between core. Coil. And geometry has made me re-think the design of mine (more reading required)
You say that it's possible to connect multi jt's.. what transistor/switch would you use on the latter circuits.  As the power would get increasingly higher.
Thanks Nick

Hi Nick,

I think it is important to note at this point, that latter circuits do not necessarily need secondary transistors. (they can be used)
The switching done by the primary transistor, causes a sinusoidal output on the secondary of the JT. This can be tied directly to a second inductor without the need for switching. Also: adding more transistors, causes more problems with synchronization. i.e. - differences in timing between switching. also, you basically need to rectify the A/C back to D/C to run it through the second transistor.... not needed..

just coil the secondary onto the next inductor.
keep in mind, that core / coil resonance should be maintained also by any secondary transformers..
