I wondered if Meyer ever did the flat coil style for the chokes:

"The Voltage Intensifier Circuit is a bifilar pancake coil transformer which provides distributed capacitance and inductance to the tube sets in the Cell. Its function is to manage the transfer of potential through the Cell, while inhibiting the passage of current by the circuit."

I see absolutely no proof of this claim. Probably idea for taking advantage of concept but....

That isn't Meyer's words, that is from some stuff posted at:
OS:Water Fuel Cell - PESWiki

page 6-3

"axially (spiralled) Bifilar wound about core bobbin (502), forming individual
spiral-wrap (inner to outer circumference and being equally-length) coils (501a xxx 501n) electrically connected in sequencial order to form resistive pickup coil"

The resultant tri-coil configuration (Inductance core 53 - choke coils 56/62 - primary coil 26 - secondary coil 52), now, allows magnetic field coupling (71a xxx 71n) to pass through both resonant-coils (56/62) and secondary coil (52) simultaneously when primary coil (26) is pulsed energized by way of incoming pulse-train (46a xxx 46n). In doing so, magnetic flux-lines (71a xxx 7In) are induced into spiral-wrap coils (505a xxx 505n) to produce inductance coupling (511a xxx 51 In) between each secondary spiral-coils (505a xxx 505n) which are parallel formed to expanding magnetic flux-lines (71a xxx 71n) ... producing step up voltage potential of positive electrical intensity (positive voltage potential) by way of inductance / capacitance interaction across secondary coil-assembly (52) while keeping opposition to electromagnetic build up to a minimum.

That means PRIMARY, SECONDARY AND BIFILARS (can be) on same core so they are wrapped around a core and not flat style. At least in this description. The tech brief is a compilation of just about all his chronological events.

The circular-spiral turns of wire (forming parallel electrical surfaces) is separated by an Insulated Dielectric Coating Material which forms a series of capacitors (Cda xxx Cdn) when magnetic flux-lines (619a xxx 619n) produces Electromagnetic Coupling Field (621) during pulse on-time (Tl), as illustrated in (640) of Figure (7-3) as to (690) of Figure (7-8).

The resultant Amp Inhibiting Circuit Figure (10-1) as to Figure (10-3 A/B) further allows amp restriction (minimizing current leakage) to be continued even if applied "Voltage Amplitude" is increased. The length and diameter size of the copper-wire spiral wrapped coil (56/62) of Figure (10-1) being paired together and electrically energized in conjunction with applied Voltage Pulse-Frequency determines how much "Amp Leakage" will occur across capacitor Gap (Cp) while "Voltage Pulse-Potential" (Va xxx Vn/49a xxx 49n) of "Opposite polarity" (B+/B-) is/are allowed to be applied across "Electrical Voltage Plates" (Voltage-Zones) (66/67). To reduce amp leakage still further, the copper wire of both Resonant Charging Chokes (56/62) can be replaced with an magnetically ~ductive stainless steel wire (430F/FR) having a resistive value (Ohms) to the flow of electrons while taking on the capacitance and inductance characteristic of a coil wire. VIC Bifilar Wrap Coil-Assembly (10-3B) and VIC Dual Coil Wrap-Assembly (10-3A) both utilize either "E"& “I” and "U" Inductance Core configurations to concentrate Mutual Inductance Fields (Rp l/Rp2) in order to optimize Amp Inhibiting Process (750) of Figure (7-14). "E" “I” core shape (10-3B) is most preferable since amp spike surge is minimize during repetitive pulsing operations.

Many examples he gives of primary/secondary and both inductors on same core. NOT pancake style...so misinformation by anyone who says it is?

When primary is pulsed ON, the magnetic field in the core that is created will cause the inductors to charge instantaneously and NOT just from the + potential moving into the inductors. It will be both. Also the OFF pulse inductive collapse moving forward is NOT just the from the inductors alone but the field created by primary coil turning off collapsing.

I think this is the direction to go... too many references by Meyer himself where all the coils are on the SAME core.
