So a langmuir torch created by the spark plug gap in the hydrogen
atmosphere to produce mono hydrogen with reactor temp controlled by:
1) Plug Voltage/gap distance/arc
2) Distance from plug to core/microparticles of Ni/other
3) Removal of heat thru heat xfer surface/fluid
4) Maybe every once in awhile they give the plug a good jolt and arc
to the powder to fluidize/mix things up a bit to solve quiesence
5). Trick is to operate torch/reactor > 600 C and below melting of
micropowder. Too high temp or arcing of torch to powder "welds" the
powder together and over time kills the highsurface area needed for NAE.
The arc is maintained independently of the workpiece or parts being
welded. The hydrogen gas is normally diatomic (H_2 ), but where the
temperatures are over 600 °C (1100 °F) near the arc, the hydrogen
breaks down into its atomic form, simultaneously absorbing a large
amount of heat from the arc. When the hydrogen strikes a relatively
cold surface (i.e., the weld zone), it recombines into its diatomic
form and rapidly releases the stored heat. The energy in AHW can be
varied easily by changing the distance between the arc stream and the
workpiece surface. This process is being replaced by shielded
metal-arc welding
<http://en.m.wikipedia.org/wiki/Shielded_metal_arc_welding>, mainly
because of the availability of inexpensive inert gases.

Guys,
The original DGT lab bench photos also showed what looked like a
spark plug wire and some type of plug (without ceramics) as far as
I could tell. Also a large ground wire on the reactor block

I know I am harping on this spark plug thing, but the
sooner "replicators" get over this doubt, the sooner we
can focus on the corect replication design. It does
appear the evidence for sparks being integral to the
process is mounting.
I agree.
The notion that the spark plugs are only being used as a plug
to fill a hole is ridiculous. There were several spark plugs
lying on the table in one of the photos. Why would they have
several if there were only being used as plugs?
Several spark plugs lying around tells me they are having
trouble with them. I'm only speculating here, but perhaps the
electrodes are fouled by powder.
