H-Cat output gas goes to zero

In measuring the gas after the catalytic converter, we discovered that at first the rate is nearly the same as the incoming gas, then it drops to zero and goes to vacuum as some kind of reaction commences. We also tested the flammability of the exiting gas, and it does not ignite.

By Sterling D. Allan  
Pure Energy Systems News

I spent a few hours April 29 at Darrell Jacobson's place in Fountain Green, Utah, USA, testing some parameters with the new power supply and the H-Cat. (For those of you who might be new to this topic, and "H-Cat" is where you run HHO or Brown's gas [product of electrolysis of water] across a catalytic converter [e.g. same as used in car], which converts the HHO back to water, but seems to produce more heat than what pure catalysis could account for -- possibly due to a LENR [aka cold fusion] or other anomalous reaction taking place.)

Output Gas Goes to Zero

One really interesting thing that we witnessed was taking the incoming HHO gas tube and placing it under water so you could see the rate of bubbling. Then we hooked up the gas to the catalytic converter to see how much gas was emitting from the end of the catalytic converter, also bubbling under water, to compare the rates.

The first time we did this was with just the raw catalytic converter, and within just a few seconds the rate went from near the same as the input gas, to nearly nothing, then it stopped completely and began going to vacuum, sucking the water up into the tube above the level of the water tub. Without the aluminum fins on the catalytic converter, it starts getting hot quite rapidly.

Next, we added the aluminum fins back onto the catalytic converter, to help dissipate the heat. This time, it took 2-4 minutes before the exiting gas came to a stop; and the vacuum reaction began much more slowly as well.

Then we placed the catalytic converter in the water bath. This time, it took nearly 15 minutes for the exiting gas to diminish to zero, and the vacuum took a while to develop as well.

I'm guessing that the reason for this has to do with the catalytic converter matrix needing to get up to a certain temperature before the full catalytic reaction consumes all the incoming gas. The longer it takes to get to that temperature, the more gas exits without catalyzing back to water.

Apparently, something is able to happen even before that point, because the incoming gas is able to create heat by passing across the catalytic matrix.

Output Gas Does Not Ignite

One of the tests we've been wanting to run was to see if the exiting gas ignites like regular HHO does.

It doesn't.

You've all seen the videos where people bubble HHO gas into a soap solution then ignite the bubbles with a flame, creating a large POP!

We wanted to see if the gas emerging after the catalytic converter could ignite. However, though we got soapy bubbles, we never got them to ignite. Once, it seems we got a really faint pop of 2-3 bubbles, one after the other, but they did not pop or ignite the neighboring bubbles.

When we tried the same thing by running the HHO gas straight from the generator (without passing through the H-Cat), the POP was so loud it caused my ears to ring and my heart to race.

When we had the catalytic converter submerged in the water bath, so the gas was exiting from it for nearly 15 minutes, those bubbles did not ignite, and I would dare say that there was easily enough exiting gas to rule out that we were just dealing with whatever air was in the tubing and in the catalytic converter at the start.

Aluminum Fins Keep H-Cat Cool

We tried running a high volume of HHO gas through the H-Cat when it had a bunch of aluminum fins attached to it to dissipate the heat. The fins were very effective at extracting the heat and preventing the H-Cat from heating up. After half an hour of gas flow through it, the H-Cat temperature raised only 2 ΊF. But when we removed the fins, the H-Cat heated up rapidly. It was too hot to touch within a couple of minutes.

Things that Go BOOM!

We had several flashbacks (heat of the matrix ignites the HHO gas). The first one scared us pretty bad. 

We had just taken the aluminum fins off the catalytic converter, and it had a metal cap on it. I don't think we had the system running very long at all before "BOOM!!!" - the metal cap blew off, not at a tremendous speed, but enough to fly several feet. Wish we had the camera rolling for that. It was classic to see our reaction and surprise -- totally unexpected as we hadn't experienced a flashback yet.

Lemon Power Supply

Unfortunately, the power supply I just got from Hong Kong is not very good. When we turned the power up, well below its maximum output, it started smoking. So we'll be limited in how much gas we can produce. Also, one of the terminals got so hot that the plastic housing started melting. We had the lead connected plenty tight, so I doubt it was from resistance heat.

Amp Meter Corroboration

FYI, the Tpi amp meter of my dad's and the amp setting on the power supply were in close agreement, within about 0.5 amps.

Resistance through the HHO Generator

I took a resistance measurement from the two terminals of the power supply (with the power supply unplugged). The concentration of KOH is 15 teaspoons of KOH per 2 liters of distilled water.

This is the same set-up as we had in our first test. Same concentration of KOH, same wires (length and girth).


Here's a video showing some of this.

Coming Next

Tomorrow, we plan to do a follow-up calorimetric test of the heat being produced in the H-Cat while it's submerged in the water bath. But given the above information, before we start the clock, we will hold the H-Cat outside the water bath and let the gas run through it until the exiting gas stops; then we'll submerge the H-Cat in the water bath and start the clock at that point.
