How to make a high voltage pulse transformer at home for cold fusion

Lets term this setup a "cold fusion transformer"

End from the beginning:

1. Neon sign transformer (or any high voltage high frequency AC)

2. CW transformer

3. Marx generator

4. Traditional multi layer transformer


We want an extremely high voltage and high current output.  For cold fusion we are not hot plasma mediated like a fusor is so we need to make up for that heat with more voltage (and maybe H+ ions but that is another topic.  See my cold fusion and making gold posts).

So how can we get both high voltage and high current?  Easy, we step up the voltage while also using capacitors to store up more current.

More specifically:
We want to have a high wattage high voltage starting point.  The best starting point I have seen is the neon sign  transformers that are 15kv and 60ma.  This gives around 900 watts which seems as good as you can get for an off the shelf 115v power supply.  So we start with that.  Amazing1 sells one google: 'amazing1 neon sign'

Now this is AC and we want to get it to DC.  To do this we use one step (or more) of a full wave CW transformer .  What this does is not only change the AC into DC but also multiply the voltage depending on how many stages you use.  For practical reasons I only suggest you use one stage, and get a 30kv output.  This will make sourcing 30kv resistors and capacitors possible for the next stage, the marx generator.  Now we have a continuous current at 30kv.  However we halved the amperage to 30 ma.  Not only do we want to boost the amperage, but we want to boost the voltage much higher.  How can we do both?  A marx generator.  This device takes the 30kv to charge capacitors in parallel and discharge them in series.  This will multiply your 30kv by however many stages you have and improve the amperage because you stored up a long times worth of power and it discharges fast in pulses once every few seconds.  I suggest maybe 1-10 stages (the fewer stages the faster it should spark but the lower voltage you will have).  This will bring us up to 300kv.  Now you may ask why not just use more stages of the CW transformer instead of using a marx generator?  Well because we need pulsed DC.  In order to elevate our voltage even more we need pulsed DC.  Only pulsed DC will work to input into a transformer.  And since we want to go for insane voltages, we need to use a transformer.  Now we just make an ultra high voltage transformer.  You make it ultra high voltage by making there be big gaps between the transformer layers of the secondary so sparks can't jump the gap.  Also make sure the primary is also separated from the secondary with a big gap or insulator.

If we use a 1:10 winding (induction) ratio between the primary and the secondary we will multiply our voltage another 10 fold... bringing us up to 3 million volts or 3 mv megavolts.  Also we should have decent amperage because of our marx generator.  So we have 3 million volts of pulsed DC power.  Just what we need for cold fusion.  Cold fusion will not work with AC (like a tesla coil or magnifying transmitter) as far as I am aware because the frequency is too high to support neutron production / generation.

Also for the end transformer, you should have a soft iron core or mild steel.  As big diameter as possible.  Wind the primary (input coil) on the iron rod.  Then put insulating material then put iron foil (0.5mm-0.1mm, reduce thickness as you move away from the center of the rod) then more insulator then wrap your next layer of copper wire.  The primary and secondary are not connected but the multiple layers of secondary coil are all connected.

PS: Decided to go with a 12" long 4" diameter 1018 steel rod (onlinemetals.com) for my transformer core.  Primary will be wound first with 8 awg magnet wire.  Then 30 mil nomex sheet (insulator) then 20 mil pure iron sheet then 30 mil nomex then secondary 18 awg (not connected to primary).  Then nomex/iron/nomex (the iron sheets can get thinner as you go outwards if desired) then 23 awg wire wound up connected to the 18 awg one.  This is the tertiary.  Nomex/iron/nomex then 27 awg wire wound up connected to the 23.  This is the quaternary.  Nomex/iron/nomex then 30 awg wire wound up connected to the 27.  This is the pentary.  The guages were carefully selected based on what the input voltage is compared to the input voltage of the last coil.  So if the voltage was 3 times higher at the output of the 27 awg for example then I selectedthe next wire to have a power current rating of 3x less amps as the last one had.  I started with 18 awg arbitrarily though and worked down from there.  To  calculate voltage I used turns of the primary (92) and turns of the coil of interest.  If say the coil of interest had 184 windings to make it the whole 12 inches then the voltage doubled from the original 60kv.  If there was a secondary coil before that one I added the voltage from there plus 120v.  Then I did the new voltage divided by the previous voltage to find out how much that coil changed the voltage.  That multiplication constant then was used to divide the power amperage carrying ability of the old wire to find the awg of the new wire that carried that amount times less.  That is how I determined what wire awg to use for each coil.  The resources I used were:




So my current build is 15kv .06 amp power supply.  Feed that into 1 stage of CV multiplier to get 30 kv.  Feed that into 1 stage of Marx generator to get 60kv.  Feed that into my transformer to get 1.745 MV. My transformer will also preferably be submerged in liquid nitrogen to reduce resistance losses.  Why not right?  

Also the reason I used iron sheets was to basically effectively enlarge the iron core helping bring more magnetic flux to the outside wire coils.  Also wrap the finished thing in iron too then some nomex.  Allow it to breathe so it can soak in the liquid nitrogen which will also work as a dielectric better than mineral oil.

So the three innovative things I brought to the transformer was 1. liquid nitrogen to improve conductivity 2. stepping down the wire size in relation to the reduction of amps as the voltage multiplies 3. iron sheets between transformer coil layers. 

And of course this entire circuit, the high voltage ac through a cv multiplier then through a marx generator, then into a transformer.

PSS:  If you want you can substitute out the initial ac neon sign transformer and the CW multiplier for a high voltage DC power supply.  But I coupdn't find nearly as good (high watts) of a hv dc power supply compared to the neon sign ac transformer.

PSSS:  Actually planning on using a full wave CW multiplier so that would be 15kv x3 from the CW = 45kv x2 for the marx is 90kv x 29.1 for the transformer = 2,619,000 volts.

PS4: Always point the B field of every winding (if they are on top of eachother) up towards the north star and make sure every winding is wrapped counter clockwise (negative side up?)

PS5:  The best magnet would be a magnetized iron sphere within another iron sphere that are connected to eachother through the poles (mabye the earth is this?).  If you want to make a toroid out of the transformer by attaching iron sheet to the top and botton; attach it to the corner s at 45 degree angles.  Even just making the top and bottom of a bar "flared out" would also help.  Ideally one would want to input a frequency of DC pulses into the transformer that matches the ringing frequency of the transformer itself.  Basically the magnetic field produced on the core by the primary will induce current in the secondary which itself will induce a magnetic field (in the same direction as the primary if it is wound right; use the "right hand rule") which will induce a current in the tertiary which, by virtue of the magnetic field it creates induce another current in the secondary again... and so on and so on. Sp basically you are looking to create the highest anplitude standing waves of power; basically just look for the best ratio of power out of the pentiary vs power in to the primary.  So vary the frequency of input pulses from the marx generator (by varying the capacitance and/or number of stages, but voltage of each capacitor should be the same) to get the best ratio of output power from the pentiary vs input power into the primary.
