for this unit this is what is needed ... 

1 tv yoke feroite core ...

ill probally use a computer power supply for the source ...  not sure yet ...

its just a bigger jt ... thats it thats all ....  the heater does not care ..  it is a resistive load ...

i have a few heaters i will expairment with ... 

an old ac carbon rod unit from the 20's or the 30's and a few other styles ...

insted of the leds its a heater on the ou put of the coil ...  it still plugs into the wall but it USES MUCH LESS HYDRO ...  ;D ;)

ist!

Hi Innovation Station,

You have to remind me old man winter is coming. :) I currently run a 160 gallon outdoor furnace to heat the house. The biggest consumption of wood occurs on getting the operating temperature up to 170 degrees Fahrenheit(my set minimum); usually takes 3 hours. Once it's going and a good hot coal layer is built up it takes a lot less wood to keep it going. One of my goals is to make it hybrid where I can use an electric start from a bank of solar charged batteries to reduce this startup time. Most electric water heating elements for this size tank though run anywhere between  3000-5000 watts 240vac. Do you think a large Joule thief heater could run anywhere near this at a lower wattage?

I recently built a magnetic eddy current heater, it does work but doesn't seem very efficient. The drive motor usually heats up faster than the copper plating. 122F off the copper plate 145F off the motor. It would be cheaper to encase the motor in a sealed aluminum heat sink and drop it in the tank.  ;D

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?

I am glad you brought this up I gotta build a solar heater...

But I am interested in this ...

I wonder if we could use the joule thief with a solar cell to power a fan 5v to pipe the air out of the unit into my home with some plastic tubing ... Just a thought...

You could also use convection.

In the 80's around Boston, there was a buzz about a thing called a PAL (not the police athletic league!)
This was a box added to the outside wall of the house that had a 4' x 8' glass/ish panel facing out.
You chose the south side of the house of course, and there were 2 vents that went through the house wall. One on the bottom and one on the top.

The cooler house air was sucked into this when the sun got onto the unit and then the hotter air at the top floated into your house. There was black on the back wall. You opened and closed the vents either by hand or you rigged up a sensor.

I knew someone with this and during the long winters when my heat never turned off, her house was very warm when she returned from work and the heat didn't go on til late at night.

Jesus got a stepper motor to work with a joule thief.
You would not need much more than a 5w computer fan just to move the hot air out. I don't recall if my friend had any fan... but that thing really worked. Boston winters are very cold and her house was always warm in the day and evening from this device.

Things like this never get much press because they are so low tech. After a while people forget about it. But it did work.
My south wall was in the shadow of another house or I would have had one, too.

But IST was making hot heat from a jt type design and these things are supposed to only make cold electricity.
I thought there would be more posts on this by now.

So, Infringer, will you be making one of these?

A booster method to the passive solar collector is to put a couple low watt infrared heat lamps in the collector. Then run them off a solar charged battery through an inverter during the day time. Most pet stores sell 50 to 250watt infrared heat lamps.

This shows the basic insides of a infrared heater.

Has a Joule Thief been able to run a infrared heat lamp? Has a 12v Joule Thief been made with more output power?

Hi Dream,
I think it needs a different approach.
I think the direction to come from is perhaps to create eddy currents with the pulses.
If the formula for success can be found there, then we can make hot calrods and cook... or hot iron stix and submerge them to heat water. Then showering water can run through the heated water etc.

I used to work with the 'pap-imi' device. Briefly. Just long enough to get a grasp on the power of pulsing. I also got a chance to peer inside because the owner had to fix it and he let me have a look.

It was a timer switch running a transformer which created a spark.
The spark landed on a very large bolt.
This bolt was attached to a long steel chord which was looped half way, and then it returned to the bolt. It was covered with clear tubing.

This loop created a very powerful pulse that went out in ring form and was purely magnetic. But the magnetic pulse would travel 3 inches either way. If you put it on a part of your body, the mag would heal anything.

OK, the whole steel cord would warm up. I would need to cool it in water every ten minutes.
Now, the frequency of pulses was very low and the voltage was very high... sound familiar?

The recommended frequency went from 2.5hz to 8hz. 8 pulses per second had lower voltage but also went less deep into the flesh and was good for eyes and surface/skin problems.
1pulse per second could make you feel you had just been punched.
The explanation from the physicist inventor was that there was naturally a build up time needed for the strongest voltage/mag pulse.

Anyway, all these things fit together and they are good to describe to this group.

My reason for putting it here now, is that the probe would warm up.

So, can we use this for a purpose?

I think maybe.

ist!

When one uses a spare PC computer power supply one needs
a load, or dummy load on the +12VDC leads or the supply
may not voltage regulate properly. I use an old diskdrive
with no cable as a dummy load. Bedini people don't
load their supplies right, then their projects melt.

That is a really great idea, almost like an on-demand water heater. The magnetic heater I built using a motor wasn't very efficient. A pulsed coil would need a lot of power to create the same amount of Gauss that the magnets had; >100 lbs pull force.

I've never heard of the 'pap-imi' before thank you for sharing Jeanna. The 'pap-imi' device sounds like a low level EMP generator. Would the heat in the steel cord be caused by the resistance since the frequency is so low(almost like hooking up a DC battery to a wire, pulsed DC)?  That would be great as a low watt heating element. Any ideas on the operating voltage/spark of the 'pap-imi'?

The 'pap-imi' reminds me of reading on a EMP pulse generator with 140khz, 2inch ring with 10-30 windings would disable electronic equipment around it at about 5inches. Turning almost any metal object/part in it's range into a radiating antenna. The more power you put in the greater the radius/power. I always wondered if you encircle it with dipoles if you could keep a constant charge on the radiating antennas with a tuned pickup coil in the center to use as power tap. Almost like Don Smith's device but with a EMP burst in the center. Just another idea I haven't tried yet.

You're welcome dreamtb,
I had to describe the pap-imi because what was done there was to make thin high pulses in order to AVOID creating heat in the body. The heat on the probe happened anyway, but it was the heat in the body that was being prevented by the thin high pulses.

With the joule thief, we are learning that thin high pulses are making good and usable amounts of power... as long as we do not try to use the power in a high amperage mode as in resistive heating.
I think we must be very clever here.

I do not say I know what we must do, but it seems that the eddy currents which are unwanted side effects of induction in a spark-gap device might be able to provide heat.

Not by running high amperage but by making a spark of high voltage. And making it frequently so the metal does not have time to cool down.

Maybe it is a good idea to look at luc's threads again with an eye to heat production.
Didn't Luc have a problem with the magnet fusing to the rod? The magnet might make a difference. I certainly does raise the frequency in a joule thief circuit, even if it does lower the voltage.

Anyway, I saw ist making sparks that heated up his carbon rods.

We COULD start by setting up some sparking devices from the JTC and watch the amps draw in relation to the heat produced.
V:heat
V+A:heat
V+magnet:heat
V+A+magnet:heat.

That kind of preliminary information could set us off in the right direction.

I imagine we could measure the heat by measuring the temperature of water containing the probe end.
Maybe there is a standard way to do this...I betcha there is.

Yup,
I think this is along the same idea.

short hi V pulse
cheap to make
shocks the metal and makes it hot.

No I will not be building the same unit...

I have a new solar heater idea I will be building it could be a very nice addition to any home if it works as my mind assumes it will I am still struggling with two other projects to get done and fall and winter are closing in fast.

IST

I still can't watch  videos

I am interested in  making a heater

Can you explain  what goes on in the video  ?

I have a TV yoke and a few monitors if I need another
I have a 12V  TIP3055 setup for  powering it .....

Do you use the  original windings on the yoke?

I have not tried  the yoke as a JT yet.
I  have no  idea how the  wires on the yoke are configured

this unit was not designed to operate like the jt's do we are currently working on ..

this is verry much the arc reactor ..

but used as a heat source ... agin stage 2 operation on this unit as well

banging larger current all else the same

do not touch the out put ...

i would rewind the core and use heavy gage wire .. this idea was to heat the carbon rod .. or element 

but useing 2v or there bouts and a bit of grunt !  you do not need to rectify output for heat!

it is basically a dead short to the rod ..

ist!

but this has sparks so it is not the best choise .. it needs more work .. 

im still sanding doing flooring that kind a thing i still have not unpacked my things from my move ..

this will take place soon!

hang in there bro !  your up verry soon !  ;D ;) :) :)

Its  your baby .......so I will wait for  more details .

I was looking at the yoke core .
It is kind of a funny shape .
at first I thought that the shape might  be a disadvantage .
Then I realised  that  you can probably  stack several of these cores together ( before  you wrap ) if you need more power
