IST'S JOULE THIEF HEATER UNITS

[Foggy-Notion]

So,IST,
How much heat and what is producing the heat?
You were getting a lot of heat from the carbon rod.
Carbon is what they did use for lamp filaments, and I think it is a good beginning.

Have you made progress?

I am very interested in heat production and you were getting a lot of heat with your power supply.
After you compare it volt for volt with a 1.2v battery, how much heat would you be getting from one AA?

Perhaps it should better serve us in it's own thread, but in response to the above, I say there is a great deal of potential to the Perkins Friction Heater, invented by distant kin of mine, or should I say, re-invented, as everything has been, Ecc 1:10 ...in any case, it is not the heater shown in this youtube video...

Which in itself is Over Unity, but the friction heater I speak of has perhaps a misleading name as there is much less friction than expected, it is simply two cilinders, one spining inside the other, 1/8" space gap between them, filled with oil.  the oil reacts to the spinning by reaching 250 degrees quite fast.  A small toy electric motor can spin this soup pot contraption, in fact a clock maker could could rig it wind-up action.

I will repost this in it's own thread as well, I think.

well i have noticed some interesting things about electricity since fooling with joulthiefs. im sure anyone who has played with them noticed that hv low amp seems to power devices with less watts consumed than that device was rated for. this i believe has applied to lights thus far.

now the joule thief could be "reversed" and instead of creating a high frequency high voltage low amp current for lights (the most effecient for lighting) perhaps for heating we will find its high frequency low voltage high amperage thats most effecient. i believe using a tesla bifiliar wound coil as the pickup should achieve this easily, especially if the primary and trigger are double the windings.

i found that bifiliar coils if powered create a higher magnetic field and higher voltage (if collected by a regular coil)  but if operated in reverse they create high amps. its rather interesting. as if the increased magnetic field produced wasnt interesting enough.  i believe its been proven that amps creates heat in the "resistance" style heaters such as metal filiments or ceramics even quartz and that the voltage has less (if any) importance here like with lights.

The right frequency will do the most good considering if the frequency is right you can heat metal in seconds through a induced magnetic field.  i believe its called induction heating/welding.

hmm much testing needs to be done.

guess ill start fooling around with with the classic 3 coil joule with the bifiliar pickup on a ceramic heater element. perhaps a touch of tesla with the air core for higher frequencies and maybe a 4th coil in resonance would help.

Hi Artic you have said this:but if operated in reverse they create high amps.How do you put coils in reverse or I did not understand you rightly. Can you please clarify this?
Thanks

Opperating the coils in reverse means to use both mirrors, make beeping sound, and switch the input with the output, hence the primary becomes the secondary and the secondary is used as the primary. 

Here is that heater link...

The thing is, these heaters can be run by a small stirling engine,
And the heat produced can power that stirling engine while heating your home.
I think you see what's going on there.

Hi Foggy thanks for response. I had build a heater that you're reffering to.I did it with a water pump motor casing and put a paint can in it with about 1/8" space. but maybe I did not spin it enough fast. The other thing that I suspected that my inner container is without holes not as shown on youtube maybe that's why it did not work.

[Foggy-Notion]

The 1/8" has to be (exactly) 1/8"
Oil (not water) has to be between the pan walls,
but not filling up inner pan.  My sources swear it works.
Both pans should be of the same metal I think.
