Title: My Horvath replication project by Steve
Post by: Login to see usernames on June 18, 2017, 17:28:51 pm
Dear all,

Here the first drawings from by reversed enginering efforts of the Horvath water fuel cell, for hydrogen with a high deuterium isotope content.

Title: HELP needed
Post by: Login to see usernames on June 19, 2017, 12:45:39 pm
Dear friends,

I am looking for a laminated core for a transformer.
Size of the totall core is a 3/4 inch by 4.1 inches.

Does any body knows a shop where i can order such a core?

Thanks!

I went back to my man cave and found an old MOT transformer that i once took apart.
The top lamels  were almost the right size.
I packed some of them together and made my core!

This looks very promising.
I wrapped 1 layer paper around it and 1 layer thin tape.


Cheers

Can anybody help me a bit here?

I need to figure out how many windings the primary and the secondairy have of TR2 of the Horvath schematics.
This is what i have for information:

Input primary: 300V by 22 amps
Output secondairy with a 100:1 ratio: 30kV and 220mA
Core is mild steel laminated
Frequency: 10khz

The drawing shows a 17 windings on the primary, but i dont know if these are the real windings count....

Hope someone can add some here....

Thanks!

You should use the old formula for turns to be able to use the magnetic swing of the core... for the primary turns you find empirically the saturation point by making some few turns and apply a voltage to it at 10khz also you need at least a secondary to watch what is happening and a current indicator on the primary side

Raise the voltage until the current start to raise not linearly at this point the secondary voltage won't look like a square because it's losing the end as saturation is reached

Than you can calculate the b max of your core and use the formula

Turns = volts applied / bmax tesla / area sq m2 / frequency / factor

This factor may be 2 or 4 for pulse and square wave respectively or 4.44 for sine wave

If you can use a audio amplifier and sine wave is also good to determine saturation point as sine will loose the top round and will get somewhat distorted in shape

Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on June 20, 2017, 15:49:36 pm
I have found that when designing a transformer for  line power the b max to be used is some smaller than the b max of the material that's because as core saturates also consume power and get hot so they nomaly use 1 tesla or 1.2 depending of the material

Your core has 3/4 inch square crossextional area by 4 inches long is that correct?

Here is some info about the saturation and what i talk about the distortion of the magnetizing current and waveform

i forgot to remember you about the primary resistance and current that creates a voltage drop and that must be considered as it lowers the effective voltage being applied to the primary

I told you once that i hated transformers, did i?

Yes! Thats the thing. 300v and 22amps must be accepted by the primary.
Thats an easy calculation.
13 ohms must be the resistance of the wire.
But how does that looks like at 10khz in stead of strait DC?

Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on June 20, 2017, 22:28:35 pm
And the capacitor in series with the primary also limits the current, is it?
C5


Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on June 20, 2017, 22:51:16 pm
ok. I think i have to look at the complete charging part of the primary coil of tr2.
C5 gets charged in series with Prim coil.
But start to conduct when thyristor 1 is set to conduct.
That releases the charge of c5 into the primary, i think...

So ill guess that the 13 ohms are not needed? It will be much less to be able to receive the charge at a 10khz rate?

Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on June 21, 2017, 09:39:26 am
This 13 ohms is the xl or xc of the circuit até resonance isn't it?

This means that applying 300v in parallel will cause 22 amps to recirculate  at the primary there may be small power consumption while there is 6600 watts there circulating

There is also powerconsumption from the secondairy, is it?
Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on June 21, 2017, 18:34:10 pm
In my view the c5 is charged by the secondaries of t1 and thru primary of t2

When the thyristor fire the c5 discharge into the primary of t2 it also shorts the secondary of t1

He says on the patent that the 300v 22a is 0.1 duty cycle 10khz

He says that all this consume 480w

This mean that the impedance of the load may be around 13 ohms

Fabio, what is your best gues for the tr2 windings?
Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on June 22, 2017, 10:06:51 am
Man given the high fluxs involved i would start with the primary having very low resistance to not have any ohmic loss there... the primary should have 100mohm or less  because if you remmember the 22 amps x22 amp  x 0.1 ohm will cause 48wats loss only at the primary

(corrected numbers)

Here is the deal i think it should be used like it is an air core since the frequency 100khz of the pulse it will cause core heating

its a power pulse transformer 500w ( maybe air core toroidal would be our best option... or even iron powder core if there was a big enough core to do that ) must be one capable of 5kw @100khz i guess

as we know the c5 value we can estimate the required L1 inductance (with the secondary loaded of course)

the secondary he says is step up or also in some patent he say it can be step down.. need to think a little i will write more next post

Why KOH|?

A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way. Because the base "soaks up" hydrogen ions, the result is a solution with more hydroxide ions than hydrogen ions. This kind of solution is alkaline.

Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on August 09, 2017, 15:07:06 pm
I believe you are on the right track Steve! Basically koh disrupt the equilibrium of the molecules giving up one electron to the water molecules and remaining as a positive potassium ion equally distributed over the solution. The result as you say is molecules that are not the classical they will have much less attraction between the hydrogen and oxygen since the last have 9 electrons and share one electron with a hydrogen molecule...  for its not only partially sharing this 9th electron the one forming the oh ion will be much less strongly glued

When we add water to the koh solid flakes what happen?

Title: Re: My Horvath replication project by Steve
Post by: Login to see usernames on August 10, 2017, 17:29:25 pm
When we add water to the koh it get extremely hot, I was wandering if this heat could be useful on splitting the molecules.

I imagine a way to add water to a koh solid having electrodes arranged to pass a current thru it

Unfortunately it's not too much as to be more than required for the reaction to be spontaneous...

Heat is needed accoording to Horvaths patents.
The heat from the water and from the transformer in his oil bath.

very nice Steve... compliments !

hope it give you some results.. you will be the only one that can tell us how this electrodes shapes respond

i have re-read one of horvath patents the other day... he talks about this depolarization pulse that is able to turn off the covalent bound..

i guess this sharp ends of the electrode creates a preferable path for the reaction goes... it even increase the electric field by geometric reason

Post by: Login to see usernames on May 25, 2018, 06:46:56 am
Very well Steve!... i get the feeling that you will get great results!  i advice you to use cooking paper to separate the layers of the coil as it will absorb the oil it will help increase the layer isolation or maybe you can use thin mylar ... remember that until you take all the air out with a vacuum pump between the coils theres going to be points where ionization can occur and lead to coil destruction ... if you proper take all the air out it will be much higher resistant to high voltage,.

the anode will work as a load to the coil though

The Horvath 22 Pulse amps (not average /rms amps) comes from first deciding on the usable low frequency iron laminations  core TR2, and then adding insulated magnet wire to form primary with proper inductance. You have to use the electronics formula for L inductor  henries = C  / (I squared / E squared).L equals 1 / .005377 equals 186 times 10 to the minus sixth henries , or 186 microhenries. inductance , as measured on hand held RLC meter.  22 pulse amps  equals 300 times square root of C farads divided by L henries. At 10khz pulses per second, gives about 450Watts power. L+ C resonance has period P. 1/2 is pulse width 42 microseconds for capacitor discharge. I found 36 minor corrections to the Patent writing as I proof read it, and added modifications. TR2 primary wire is wire gauge so as RMS amps = Peak Pulse Amps times .707.

My proof reading of Horvath patent 3,980,053. It's mostly correct as per years ago. An IC driven Inverter could now days be substituted using MOSFET transistors with flyback transformer. . A purchased forward type power supply could also be used instead of Flyback type , if isolation is done with extra parts added when SCR fires..

More  proof reading corrections to my sheet, as an update.; Patent 3,98,053

col 8, line 4     1 MFD capacitor at 600-1000V rating.

col 8, line 10   20-25 Amp RMS/average rating for purchased High frequency type SCR as passing about 15amps from the Peak 22A pulse of Capacitor and rated 600 volt, due to fluctuations of power supply output volts of 300v.

col 8, line 17   OLD style TV type ferrite UU core set can be used and wires wound on bobbin that fits over both core legs. U cores and EE cores are much easier to work with . Windings have to be over each other, not on opposite halves cores. Ferroxcube 3C8 material had high inductance for windings .The larger the core, the less turns to wind for given inductance required. The less turns on primary allows for less winding turns on secondary side, because of better ratio. Various cores can be tested with same turns number and inductance meter for quality.

looks like your getting bubbles off the sharp edges that are the shortest path between the 2 poles

so the theory of Horvath is the shape gives the equal surface area on both plates?   that's what I always thought but if the 8 points are the major contributors then the concave curves are lacking , being further distance.
I don't trust Meyers, Horvath or any patents.

Your demo is the first time I have ever seen a replication of the patent drawing, on that basis you are #1 in this area.

maybe the field has to relate to this shape ?

the visual of this cell is similar to the magnetron  . Good for you , that is amazing dedication

Coil size is pretty much a standard factor.  The very same coil which will produce the desired effect with a given capacitor will still work with a much smaller cap.  With magnetism as an additional element, smaller wire in the coil will produce a stronger field.  And will affect the resonance.  If you want a specific frequency, design the coil for appropriate inductance, keeping the coil's resistance in the range of 5,000 ohms, regardless of frequency.  And you can always add a trimmer cap if needed.

That was just strait dc 3 amps.
I am now going to build that electromagnet and i will build a similar circuit as Horvath is showing in his patents.
Its about 300v and 20 amps being dumped into a coil. He wrote in his patents how many Gauss you should measure in the cell....

If you read the patents, you can see that the electrodes are nickel plated. The hydrogen is collecting some how in that layer.
I think that is part of the reason of those bigger bubles.
Maybe the sharp edges help, but the surface of the inner electrode are also not smooth. Like it was sandblasted.

What is the size of the core area? And window?

Im not sure but i think you would need a 6kva core to be able to sustain that output

The formula for the tuns is simple but the power is more complex... The first problem with high voltage is high turns makes high reactance so to have decent current output with a low voltage drop you need low inductance so lower turns higher core size


I use it like this for pulse on off

Volts/Area/bmax/frequency/2 = turns

Bmax is 1.2 for laminate steel some quality may be higher

It could be that this 220ma 30kv are at resonance?

If do than we dont need high power but certainly there is the need for a high voltage capacitance able to put this current voltage at desired frequency

What is the size of the core area? And window?

Hi Fabio,

Sorry for my late reply, but i have a lot on my head at the moment.

The inside diameter available for the " electromagnet" is diam 6,5cm by 8cm deep, round.
The core parts i have are thin metal stripes which i use to make a square core.
It can be 1cm by 1cm by 8cm
It can be bigger....2cm by 2cm..by 8cm ;)
It will probably cooled by oil.

What do you think?
