A  3-D printing file for creating spiral inserts for the electrical particle generators (EPG's)  has been posted at

The idea is to print short inserts  that twist the magnetic slurries and/or gases within the 0.5 inch copper piping of the EPG's
The work is very impressive but the suggestion that they should be inserted one after the other may lead to an unexpected result

"EPG Gas Core Helix

August 12th, 2013
Fits inside half inch copper tubing for a Stanley Meyer EPG. Print many of them and slide them in...

Excellent  work!

imho though...
If the ends of the spiral parts are not aligned to each other to allow a smooth channel between the inserts
 (let's say 90 degree rotation) then the spiral dividers are essential acting like a powder mixing column with each insert
acting to triturate or divide the slurry/gas with each pass though  an insert. In the case of a 2 fluted insert,  a passage through 3
of the inserts would be essentially  dividing i into two channels then dividing again and then once more (. 8 triturations )
 "Spitfire(r) propane soldering nozzles used a similar method to swirl and achieve excellent air/propane mixing which allowed
for a very hot flame to be able to braze with out using the more expensive  "MAP" gas/or pure oxygen..

One reason that alignment coils are used in the EPGs is to correct the turbulence and mixing of the mechanical pump drive  in
mechanical  pump EPG systems  In the gas systems, the linear drives  function both as an alignment coil and pump so the
turbulence and mixing in linear flow is less. While the dividers are essentially adding more "cores" or channels which may
 be helpful in final power output, it may be outweighed by increased resistance to flow and turbulence effects.

Note for calculations

Some of the factors be considered when using the dividers

1. The number of twists per unit length of divider                    This affects the angle of the magnetic flux cutting the pickup coils and power output
2. The volume  of the inserted divider per unit length               This decreases amount of gas/liquid per length of channel
3. The increase of surface area contacting the liquid or gas      This affects rheological flow resistance and back pressure
4. The decrease in volume or gas/liquid                                    This decreases magnetic susceptibility and flux strength per length of  channel


One possible solution to the dividers is to make a  very long spiralled helix from silicone rubber with 2 to 3 flutes and to pull this through the
copper channel. Since the friction to do this was significant even when  the copper tubing was pre-lubricated with Teflon DriLok(r) or low
viscosity Syltherm(r), another approach is to fabricate the tiers in sections o f10 or 20 ft lengths of straight tubing.  . In the multi-tier systems
each spiraled tier required approximately 180 inches of tubing  is required depending  upon arrangement of the tier connecting tubes, so standard
20 foot length are  sufficient.

1. A long silicone helix is then pulled down through vertically and twisting the helix slightly to reduce its diameter (similar to threading a needle or
when making rope)  Once the silicone divider helix is through first section,  another length of the helix is threaded through the next section
of copper pipe  or tubing  until six or seven are made, one for each tier. Then the soft copper tubing is coiled into the spiralled tier  using a jig
made from an oil drum or other spool such as a wooden cable spool.  Since both the helix and copper are flexible  (  because the temper of the
copper can be removed prior  to helix insertion  by heating the copper tubing or pipe,
Then the copper channel with helix inside can be formed into the spiralled configuration
2. The pickup windings are then wound upon  each tier using a toroidal  transformer winder or other similar device
3 The completed tiers are then fitted with. 90  or 45 degree connecting "ells" being careful not to damage tie
silicone twist helix by excessive heat and also to remember proper offset angle  due to connecting outer and
inner ends of the tier openings.
