@ Gadgetmall:

Good work!!  How deep into the earth are your electrodes?  You will get more amps (mA's) with the plus one being deeper than the minus one at the same dip angle for your location.  I am hoping to hook mine up outside but it is 12 degrees F out there now going down to -2 later.....cold!!!!!!!!!  Good post.

Battery voltage is not a good indicator of the amount of charge left in the battery.

An ammeter is a voltmeter and a resistor. Ohms law gives current in amps = voltage across resistor divided by resistance in ohms. If you put a 1 ohm resistor in series with the battery and measure the voltage across the resistor, then the current going through the resistor in milliamps will be equal to the voltage across the resistor in millvolts.

boy do I feel dumb!!!  ha I just did exactly that with my 12 volt battery making HHO.

Cool. OK so,

I don't have a 1 ohm but I do have a 10 ohm, so

E=IR
I=E/R
R=9.5 actual
E=0.220
I= 0.023A

So, it appears that my hybrid jt draws 0.023A

YEAY! Thank you xee2.

@the NOP I cannot get any reading across the LED. ziltch, nada.  Thank you also.

and thanks everyone for not laughing  , (but go ahead, because I am!)

voltage reading or ohm reading ?
for ohms, reversing the polarity might help.

This is better than christmas morning.

@AbbaRue, thank you for such an excellent explanation.   wow.

@Sparks, I was wanting to ask about creating a heat lamp from some IR leds whose rays were caught in a small greenhouse-like enclosure then whose heat was pushed out into a room for space heating. I know you are more inclined to theory, so, I want to ask if there is a theoretical stumbling block here that would need to be stepped over?

Along the same lines and from my less knowledgeable understanding than these 2 above posters, I awoke this morning wanting to post some thoughts that have been rumbling in my head ever since I was successful with the first fuji circuit.

Our man N Tesla never intended for us to be plugged in. He said he had it in mind to send the power over the waves or ethers or I don't know his exact words. Perhaps they would be helpful here.

His ideas centered around high frequency and, I have no doubt that he could have made (maybe did make) appliances that utilized the high frequency that he was preparing to send out from W...cliff.  We do know he made fixtures that were receivers which put out light.

I would like to suggest to those here who are interested, to start playing with motors, or non-motors that can perform the same functions as things we now have, but be driven by high frequency, not amps.

Our world could use a whole assortment of appliances that work at these high frequencies. I am talking about skill saws and blenders etc.

So, for those machinists and inventors so inclined... how about this idea?

@all
and along these lines, this is so easy to make a small energy source provide enough hi frequency to do a lot.  functionally a lot.

I just looked at my mk1/jt hybrid which I made yesterday and tested last night. That lit the array at the blazing level for 10 hours and the total drain on the battery was only 0.161V. So, in other words. I still have a well charged battery after 10 hours of producing blazing light.

I also want to ask those who are able to figure the calculations of these things to give me some numbers.

The battery is AAA and "holds" 750mA
The resistor is set at 1K ohm on the base of the 3904 transistor.
The transistor is only on for a part of the time, based on the resistance. and perhaps it also changes over time as the battery discharges some.

My little tests are OK for now, because I am doing them all the same etc.

Is there someone who would like to tackle this question of how much I am using in these tests?

Xee2 and AbbaRue came to mind, perhaps there are others.

Thank you,

jeanna

        Interesting concept.  Infrared diode arrays powered by a voltage multiplier circuit.  They have the quartz tube heaters but again this is a very inefficient way to generate ir.  Water readily absorbs infrared converting it to moleuclar vibration while air is pretty opaque to this freq unless there is a bunch of co2 to absorb and reflect it.  Perhaps a water heater first or a portable heater like the quartz tube heaters.  It would be interesting though to get some steam vaporized in a low pressure tube and see if ir could ionize it and create a water plazma bulb.

     Thanks ,I'm Tickled and amazed that they are lighting perpetually i hope from the Earth battery i just threw together last week . The 3/4 inch galvanized pipe is 2 feet and even with the ground so my lawnmower don't hit it . It is Negative .. The small copper tubing is only a foot in the ground and i stomped the rest in the dirt so its covered . Its positive . they are less than a foot apart facing north south . I poked around a bit checking that theory and yes it puts the most voltage NS . I will have to get me a longer copper pipe as i see now that is why i get hardly no Ma's .I just wanted to see if the ground really did put out voltage and had it powering a Small Analog meter full deflecting most of the time when i first hook it up then it goes down a little . I wound these toroid's from one of those grab boxes for 3 bucks at Goldmine  . I can tell you that mine had 1000's of leds toroid's transistors switches motors magnets coils ,Pots,resistors capacitors diodes tiny relays super caps and i could go on and on . I can stock My shop now all with a 3 dollar grab box . it weighed over 5 pounds .. So if you ever wonder about those suprise grab boxes they have 1000's of dollars in parts if you have to buy them all separate :)As for My 9Th and Tenth Joule thief i was very precise in winding them tight and pretty  and it paid off with LIGHT !!I'm Still Experimenting !
