The Filling Station

Stan's twin brother filed a patent in 2004 with seven figures on it. Two of those drawings, between them, give the one number the patent never states — about 82 nanofarads of wet array — and nobody has ever checked it against a real cell.

What was shown

Stanley Meyer had a twin. Stephen Foster Meyer filed his own patent on 22 April 2004 — Hydroxyl Filling Station, published as US 2005/0246059 A1 — and it is a different kind of document from his brother's. No new physics is claimed. It is a machine built out of parts you can buy, and every part on the drawing has a number that appears in the text.

Dual three-phase generators feed six impedance matching circuits on three cards, driving six triple-element arrays submerged in a water bath. A jacket cools the cell. A computer runs it, and its source code was filed with the application. The gas goes through a liquid trap, a flow restrictor, a compressor, a storage tank, a safety cut-off and a flashback arrestor before it reaches anything.

The numbers that are printed on his drawings

from
Fig 5 header drive frequency 496.9 Hz, 1.67 ms/div
Fig 5 traces Signal A / Signal B +3.5 to +15.5 V / −4 to −16 V about a 0 V middle element
Fig 4 fuse per phase 6 A slow blow
Fig 4 parts NTE5817 Schottky, 1.7 mH chokes, 68 µF caps, 10 MΩ bleeders
Fig 6 header the ring at T1 13.5 kHz, about 30 V peak to peak

Usually got wrong. The three phases are often described as rectified into a six-pulse supply with 13.4 % ripple, and "twelve pulses a cycle" with two generators. Fig 4 shows no common DC bus: each phase goes through its own fuse into its own card and feeds one array, half-wave rectified and LC filtered, exactly as Fig 5 draws it. What three-phase actually buys him is in Fig 3 — the six arrays sit 120° apart, so "not only is the gas produced between the elements in an array, but also between each array".

The number nobody has ever stated

His array's capacitance is not written anywhere in the patent. Two of his own drawings give it:

  • Fig 4: L = 1.7 mH
  • Fig 6: the ring = 13.5 kHz
  • so C = 1/(4π²f²L) = 82 nF of wet array

And 1.7 mH with one 68 µF capacitor resonates at 468 Hz against his 496.9 Hz drive — six per cent apart. The card is not just a matching pad; it is a tank tuned near the generator, which means the drive frequency is not a free choice.

The sentence worth an afternoon

the frequency of FIG. 5 is adjusted to match the electrical wave-length of the arrays 132 and the impedance of water bath 133

Two jobs in one clause, and they live in different worlds.

Matching an electrical wavelength means making the element a resonant length. In water a wave travels at about a ninth of its free-space speed, so a three-inch element is a quarter wave at 111 MHz. At his own 496.9 Hz a quarter wave in water is 17 kilometres. Nothing is standing on that tube — and he did mean physical length: "we took a bunch of tubes and we cut them off at a certain height. There's a reason for that, because if you look at wave guide theory, you know that you have a frequency, it's like an antenna."

Matching an impedance is the other thing, and it is the one his circuit does. He understands it completely, and says so in 2007:

Marconi found out that the atmosphere has 50 ohms impedance… if you don't match the impedance, you get a reflective wave, and the wave energy that's reflected back is like 90% of what you're trying to push out

A source delivers the most power into a load equal to its own impedance. It needs no resonance, it is true at any frequency, and the peak is broad: you keep half the available power across a 34:1 spread. (The 50 Ω in the film's curve is his number, not ours.)

Why he cared

I get to a certain point, I'm drawing 40 amps, and I hear my alternator growl. Well, you know, it takes 12 horsepower to drive an automobile alternator, and typical alternators will put out about 35 amps… there's a mismatch

Twelve horsepower is 9 kW at the crank; 35 A at 14 V is under 500 W at the terminals. That is the practical reason this patent has generators and matching cards instead of a battery.

What he quietly got right

decision why it matters
the rotating phase relationship gas between arrays as well as within them — nothing in Stan's work does this
water jacket and filter cooling 60 °C → 25 °C roughly doubles cell resistance; para 50 says the filter is "to help control the operating impedance of the cell"
purge first, claim 8 the software will not proceed until it has found no leaks
trap, restrictor, check valve, relief valves, cut-off, arrestor hydrogen and oxygen premixed is not a thing to be casual about

How fast, from his own fuses

Usually inflated. Figures like "100 amps per array" and a 5,000-litre tank get quoted. Neither is in the patent, which gives no tank size at all and fuses each phase at 6 A.
six arrays at his own fuse rating 36 A
by Faraday, at 100 % about 16 litres of hydrogen an hour
a 5,000-litre fill about 300 hours

The name is still right. It is a station: it fills overnight, like charging a car. That is a design, not a shortfall.

What nobody has done

Published an impedance match on a Meyer-type cell. Measured the ring at T1. Measured an array's capacitance wet and compared it with 82 nF. Swept impedance against temperature. Read the nineteen pages of source code filed with the application. None of those is a research programme.
