Anyone who has spent time working on internal combustion engines (ICE) knows that when an ICE runs rich (too much fuel) it will eventually foul the sparkplugs with a dry powdery soot, which has a high carbon content. The sparkplug insulator turns black from these deposits and becomes conductive, thus, destroying the insulating function essential to its operation. This basically connects the center (hi-Voltage) electrode to ground thru these carbon deposits, and the spark no longer occurs, and the engine won't start.
However, an interesting side note is that if you pull off the sparkplug cable from the sparkplug, and hold it a little bit away from the sparkplug, creating a spark-gap (you can hear the arcing), and try to start the engine, it will run. As soon as you put the cable back on the sparkplug, the engine will start to die; pull the cable a bit away and the engine will start firing again. you can only do this so long before the SP becomes so fouled that nothing will help. If any conductive particulates inside of a working LENR reactor get deposited on the sparkplug, it will eventually cause a similar failure. I'd be curious if using my above technique on a failing LENR reactor would at least keep it going for some time after it would have certainly failed to run. Wondered if the kind of spark-gaps used on large tesla coils might help, but they too have some kind of insulating element which would become fouled as well. the longer the insulator, the longer it runs. might buy you a few more hours/days, but eventually it would fail. Unless you put the entire hi-V supply inside the reactor, you're gonna need some kind of insulating element to separate the hi-V electrode from the reactor wall (which I assume is conductive and grounded). what if the entire reactor vessel, although metal/conductive, was floating (electrically that is!). no, you still need a return line. just don't see a way around this, other than eliminating the need for spark, or eliminating conductive particulates floating around (literally!). -mark From: Jojo Jaro [mailto:jth...@hotmail.com] Sent: Sunday, July 15, 2012 12:45 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:Harping on the Right Things! I supposed DGT can replace spark plug for glow plugs to misdirect, but that would still not explain the temp spike. Sparks are the only mechanism that can bring H2 temps that high and then quickly back down again. Glow plugs will not result in a temp spike. When you look at the end plates of DGT reactors, you will notice that the thermocouples are very close to the spark plug. A series of sparks would quickly raise the temperature of the H2 gas in the vicinity of the sparks, which is also where the thermocouples are. Then a second later, the hot H2 gas diffuses and the temps are down again. Hence a temp spike.

After surfing the different glow plugs on the web, I believe that Jojo is correct, that what is shown in the pictures offered by DGT are probably spark plugs. However, might there be misdirection in DGT's pictures? Would a glow plug screw in place of the spark plug in their reactor? DGT could have put the spark plugs in their reactor for the pictures, while they normally use glow plugs in those positions. The spare spark plug on the table was obvious and suspiciously left in the open. Another possibility is that DGT found that the glow plugs were wearing out too quickly and they modified their reactor for a different type of heater that would have greater life. Since they were left with the tapped glow plug holes, they plugged the holes with the spark plugs. The spark plugs are never shown connected, but everything else is shown connected. The comment from W&M about DGT having trouble with the glow plugs not lasting long enough goes with what Jojo observes for a glow plug. I am not convinced either way.

Like I said, they don't last very long when used continously as would be the case if DGT were using these to heat their reactors. A heating cartridge would make more sense for heating. I tried using glow plugs in my first generation reactors with so-so results. They tend to overheat and melt your ingredients. Hard to control heat output. They are designed to heat fast and furious. Controllability is not an issue for their intended application as Diesel engine preheaters as they are fired only for a few seconds. but, even in their intended application in diesel engines, they are one of the more frequently failing items. Jojo PS. Those pictures are definitiely spark plugs. No question about it. ----- Original Message ----- From: Alain Sepeda <mailto:alain.sep...@gmail.com> To: vortex-l@eskimo.com Sent: Monday, July 16, 2012 2:14 AM Subject: Re: [Vo]:Harping on the Right Things! using a glowplug for heating is very natural, since it is very resistant, cheap, and easy to find. -- Regards, Bob Higgins
