Pure Energy Systems News

March 15, 2014

As you've noticed by now, I'm very excited about this H-Cat discovery that Justin Church made in January, in which HHO is vented into a catalytic converter, and copious amounts of heat are generated as the HHO goes back to water.

Given that the amount of heat produced appears to be so much more than the energy required to produce the HHO gas in the first place, and given that the components in the catalytic converter are nano-platinum and nano-palladium, and given that HHO contains a highly energetic form of hydrogen -- providing all the needed ingredients for LENR -- it seems extremely like that we have an LENR process taking place here, using off-the-shelf components. But also there is going to be the standard chemcical reaction of HHO going to water and heat. The overunity will be a function of LENR.

Catalytic converters can be found in any auto parts store. There are thousands of HHO generator companies in the world, as well as kits and plans you can download to make them yourself from locally-obtainable components. It's basically an electrolysis process.

It just seems to me that FINALLY we have found an ideal open source project: something that is affordable, easy to build, easy to understand, safe, with unencumbered IP, and which provides a practical output. And as far as I can tell, there is nothing holding us back from beginning to roll product out right now.

Certainly we can improve the output by optimizing the design but it seems to me that we can piece together off-the-shelf components as they presently exist and begin making products that we can sell as safe, clean, and affordable.

And any of you are welcome to launch into this. That's the beauty of open source.

Let me just remind you that one of the ethical principles open source is to provide royalties to those involved in the design you utilize. For example, if you build these and start selling them, you should send Justin a 5% royalty on all items sold. Let's use this opportunity to show the inventors of the world that open sourcing can be a very fruitful way to roll out a disruptive technology. Do the right thing. Send a royalty -- not just to Justin, but apportion it to others also significantly involved in the design as it comes to you.

Even if it's not LENR: Even if the system turns out not to be LENR or some other exotic reaction, indications are that at a minimum it will be a super-efficient heater.



We cannot be held responsible for what may happen to you or others as a result of your implementation of this information.


Safety issues:

Brown's Gas will ignite when presented in a high enough concentration to an ignition source, whether flame or heat and you are creating conditions of sufficient heat in the catalytic converter, so you have to be careful about HHO concentrations reaching that heat source.

You should use some kind of insulation, such as ceramic insulation pads, between the incoming HHO and the catalytic converter.

You don't want the HHO generator to begin to dry out (with input reservoir going dry), or you can get arcing between the plates, which can ignite the HHO gas. The first hazard is explosion, as the electrolyte level gets so low that the electricity starts arcing across the plate gap. Then, depending on the electrolyzer design, you may get meltdown, electrolyzer bursting and/or fire.

If this in indeed LENR, you can expect transmutation and radiation, and should check for the same. So far, Justin and his associates have not detected any gamma or beta or alpha radiation and they are in good health, notwithstanding having been around the effect for many hours.

You will be dealing with significant heat and should use necessary precautions.

Impurities in the catalytic converter can be released and inhaled. If you are going to be operating this indoors, you need to be sure to have a clean substrate in the catalytic converter.

The electrical components involved in generating HHO gas can be dangerous if not properly handled.

If you use a battery source, be aware of the cautions regarding battery handling: shock, acid exposure, gas leakage/accumulation.

See OS:Justin Church's H-Cat.

Certification Requirements

If you are going to be selling these systems, you should check with your local regulations regarding heating appliances. There may be requirements for certain certifications before selling anything commercially.

In most places, you can sell beta testing systems without having achieved those certifications, within a certain window of time (e.g. 6 months).

Construction Principles to Bear in Mind

Here are a few things to bear in mind in designing/implementing/experimenting with a system.

Probably Any Newer Catalytic Converter will Work

From what I understand, it doesn't really matter what brand of catalytic converter you use. Pretty much every catalytic converter in the past decade contains nano-platinum and nano-palladium in the ceramic matrix.

I'm guessing that the rate of flow of HHO that can be handled (and thus the amount of heat that can be generated) will be a function of the diameter size of the catalytic converter.

Remove Insulation around Catalytic Converter

Off-the-shelf catalytic converters are going to have insulation around the perimeter, but this is not desired for a heater application.

Either this will need to be removed (if not too difficult and you may want to select a model based on how easy it is to remove the insulation barrier), or perhaps a manufacturer would be willing to let us obtain just the matrix part of the catalytic converter.

Update: is willing to provide the catalytic converter without the insulation, inside stainless steel pipe.

Replace with Single-layer Metal Sheet

Then you'll want to wrap the substrate/matrix with some kind of metal or piping that can be made air tight (to prevent entrance/egress of gas) by a seam weld.

Update: is willing to provide the catalytic converter without the insulation, inside stainless steel pipe.

Orientation of Catalytic Converter

Since water will be forming in the catalytic converter as the HHO gas is catalyzed back to H2O, there will need to be a way to drain off the water. Vertical is not necessary as long as the slightest incline in the collection area allows for drainage.

HHO Gas Flow along perimeter may be Ideal -- NOT

Since the primary object here is to provide heat that can emanate to the exterior and be radiated, I'm guessing that the best design would be to have a 1/16 to 1/8 inch gap around the entire perimeter of the catalytic converter matrix, so that as the HHO gas flows along the perimeter, it will react there, where the heat is closest to the radiating surface.

It turns out that the perimeter of the matrix is solid ceramic, required for the matrix to hold together, and it is impervious to gas. So my idea of having the gas purposely flow along the perimeter is moot.

HHO Gas is Lighter than Air

Bear in mind that HHO gas is lighter than air, so the natural direction of flow is upward. By forcing the HHO gas to flow downward, then the time of interaction with the substrate is likely to increase. That's the thinking anyway. You'll want to experiment with this to see what is best.

Backflash Arrester

You need some mechanism between the catalytic converter and the HHO generator to prevent backflash from reaching the HHO generator.

Options include: Bubblers, back-flash arrestors.

Bubbler: Simple hardware, cheap to buy/build, maybe $20-75.

More than one mechanism would be a good idea.

Insulate Catalytic Converter Entry to 1) Diffuse gas, and 2) Prevent Backflash

Justin recommends placing ceramic insulation pads in the opening of catalytic converter to both diffuse the incoming HHO gas (so it doesn't hit the matrix in a concentrated way) and to insulate the HHO nozzle from ignition from the heat being generated in the catalytic converter matrix. (Justin recommends stacking from 10 to 30 of the ¼-inch thickness size.

Pretty Much Any HHO Generator Will Work

There are sure to be gradations of quality in HHO gas that works best in this process, but I will guess that ALL HHO gas mixtures will work well enough to be worth while. So really, to get going on this, you just need to find an affordable HHO generator that produces gas at a rate of at least 1 liter per minute.

Various names of HHO generators: Brown's Gas, hydroxy, iHHO

You'll also need to get any operational supplemental material required, such as...

Electrolyte (required in most HHO systems, but not all)

Power source for HHO generator (battery, replenished by renewable power or mains power supply), able to provide the proper volts/amps (Justin sells these too).

Bubbler, flashback arrester.

Heat Emanation
Image:Heat-Sink ChemCar 300.gif

You'll need a way to efficiently extract the heat from the catalytic converter.

I'm thinking that aluminum heat sinks would work well. Raphial Morgado told me that Aluminum tends to disseminate its temperature evenly among itself. From this we know that the temperature it is picking up on the surface of the catalytic converter will be distributed among its fins, and passing air (e.g. blowing air, from a fan).

Alternatively, you could drill holes through the catalytic converter and pass water piping through it, but you would have to make airtight welds around where the pipe penetrated the catalytic converter, and that would not be easy. Probably more trouble than its worth.

Bear in mind that air convenction is a very inefficient way to transmit heat. Early designs, prior to re-engineering of the catalytic converter itself, should focus on having the exterior aluminum heat sink dump the energy into an external heat exchanger (passing through the aluminum heat sink)....

Vibrate the Catalytic Converter to Prevent Water Build-up

Ideally, there should be a way to prevent water build-up in the matrix. Once water accumulates on the substrate, the HHO gas ceases to interact with the substrate. The system has two built-in sources of vibration, at two levels of intensity and frequency: the bubbler, and the fan (and, arguably, the power supply).


Somehow structurally place a rod fastened both to the bubbler and to the catalytic converter.

Also place a rod fastened both to the catalytic converter and the fan. A fan that has a front end that can be fastened to would be ideal. (Most front ends of fans are not designed to be affixed to anything, but rotate with the blade.)

Have a rubber mounting for the fan so it isn't attached solidly to the cabinet, so it is more free to vibrate. (This will, of course, introduce additional wear on the fan bearings, so this will need to be factored).

Have a rubber mounting for the catalytic converter so it can more easily be vibrated from the two sources mentioned.

INDIRECT MECHANICAL LINK. It may be that the cabinet itself could serve sufficiently to convey the vibration of the fan and of the bubbler to the catalytic converter.

Fasten the fan and catalytic converter steadfastly to the cabinet, which will convey the vibration from one to the other.

Have the bottom situated on rubber, to reduce the amount that the floor would otherwise dampen the vibrations you want to be transmitted from the fan and bubbler to the catalytic converter.

(In my first build, I'm going with the assumption that this latter method of water build-up abatement will be sufficient.)

Heat-Resistant Materials / Insulation

There shouldn't be any materials used that can be damaged or degraded by heat.

Sensitive items, e.g. the HHO generator, and power supply, should be insulated.

I recommend having a insulated wall/barrier within the cabinet between the fan/catalytic converter section and the HHO-generator/bubbler and Power Supply section. This way, the orientation of these items could be so you see their widest portion when you open the cabinet for servicing.

Water Recycling

The water that drips from the catalytic converter should be sent back to the HHO generator. The rate of water accumulation is not that great. (I'm guessing it's around a quart every two days of continuous running.)

This could be done manually by a beaker placed beneath the catalytic converter, which could then be emptied in the water reservoir of the HHO generator.

If this option is chosen, there will need to be a sliding door or other access to the water container for emptying.

Or it could be done by a hose and small pump.

It's conceivable that the HHO generator water reservoir could last for a month if this were engineered properly, losing only to evaporation, which will be minimal.

Later models could be hooked up to a water supply to keep the reservoir filled.

One way to set up the water recycling would be to have a plunger in the container under the catalytic converter, and when the chamber is "full", the pump turns on and then is turned off when the plunger goes down to a certain level.

Factoid : According to Wiki Answers, at 1 atm, at room temperature, there are 1334 liters of HHO per liter of water.

Water Catchment

In the case you are not using a water-recycling system...

Since there is a likelihood that the unit operator will not always remember to empty the water container before it overflows, there should be some way to either catch the water in a secondary pan (e.g. baking pan) under the water container, and/or a drain in the bottom of the cabinet with some kind of container there to catch any water.

Most utility rooms are fitted with water drains, so the water drain from the bottom of the cabinet could be plumbed to go to that drain.

Small Ventillation Hole in Bottom of Catalytic Converter

There are two sources of gaseous fluctuation at the bottom of the catalytic converter. 1) continuous emission of a very small volume of un-catalyzed HHO, or Helium (product of LENR). 2) The emptying cycle for the water container at the bottom of the catalytic converter when it gets full and needs to be pumped into the HHO reservoir. That volume of water will need to be replaced with air.

Having a small hole (e.g. 1/8 inch in diameter) anywhere near the bottom of the catalytic converter would probably be sufficient to accommodate this fluctuation. This would only be needed if you are creating a closed system to prevent evaporation.

The position of the hole should not be where water will be collecting and draining at the bottom of the catalytic converter. If it is on the vertical wall of the catalytic converter, it should receive minimal efflux of water, which would immediately be evaporated from the heat of the system.

Option: Vertical, Rather than Cube

If the catalytic converter and fan are placed above the HHO generator and power supply, then gravity would serve to return the water from the catalytic converter to the HHO reservoir.

(The HHO gas will not need a pump since it will easily flow up to the top of the catalytic converter.)

Since hot air rises, this orientation will naturally keep the HHO chamber cooler than the catalytic converter chamber.


Given the above principles, here are the materials I plan on using:

Catalytic Converter

The folks at {I found them on EBay} are willing to sell just the catalytic matrix, without the standard exterior stuff. They can do standard catalytic metals in pretty much any combination, including Nickel. Their typical matrices include Palladium and Rhodium. [Palladium is probably the key here for converting HHO to H2O and heat]. They can also affix the matrix to a heat exchanger. They've already done it for some people in the Syngas industry.

For me, they

: encased it in a 4" (outer diamter) stainless steel pipe.

: Press fit a 3.66" metal-substrate palladium/rhodium, standard matrix into a 4" stainless steel tube

: The matrix is 4" long.

: The steel matrix is less dense, with 300 cells/inch, allowing for more flow, which is what we want.

: Left 2-1/4" of pipe on the one end, (for us to put our ceramic insulation, then cap for the gas input)

: The other end is tapered down (conical) to a 2" opening.

: It has no insulation around it.

: Custom catalytic converter dimensions: 4" diam, ~9" long

All this he's able to do with settings and materials they have readily available.

A simple approach is to cap a measured bottle (e.g. 2.0 L marked near top), then place it up-side-down in a 5 gallon bucket of water. Then run the hose into its opening and time how long it takes for the gas to reach the 2.0 L mark. Even cheaper and easier than the following.

Aluminum Heat Sink


Image:Aluminum heat-sink circular.jpeg

Once we get a design figured out and can do bulk orders, we can get extruded heat sinks to our specifications. Meanwhile, we need to find something that will work for now.

Possible sources: - based in China can't find U.S. source for single items - this is the shape we wan't, if we could get the right diameter - could work, affixing many, not optimal as is

Heat-Resistant Adhesive

(for fastening the heat sinks) - T4 Heat Resistant Permanent Threadlocker (~$10-30) - "...subject to high temps, like engines. T4 is not easily removed by hand tools. Once cured, T4 creates a tight, durable seal that prevents loosening and leakage from shock and vibration, and keeps out air and moisture to prevent corrosion. This adhesive cures at room temperature when no longer exposed to air, such as tightening a nut onto threads coated with adhesive. T4 cures to a workable strength in 6 hours at room temperature and reaches full cure in 24 hours."

Vertical Switch

To shut off the system in case it gets tipped over (e.g. through roughhousing).

PowerPedia:George Wiseman writes:

: A compact and less expensive option (cuts $200 off the manufacturing cost of a WaterTorch), for me, is to use an analog or electronic 'tilt' switch, so the WaterTorch will shut off if the machine is tipped more than 5° in any direction off a level plane). Then I can keep my centrally located float switch as is, and gain the functionality of shutting off if the machine is tipped over too.

: So, what you are looking for is a tilt switch. There are lots of options.

: Many portable electric heaters have tilt switches. Two examples are:

: 1. A simple mechanical tilt switch, usually using weights or

: 2. A simple 'contact' button (a deadman switch) that holds itself closed as long as the heater is sitting on it but releases (opens) when the heater is tipped.

Congress:Member:Tai Robinson recommends: "You can use a simple mercury switch dish as in an old thermostat. If the things tips over and the mercury is not in contact with the terminals, then it would be shut off."

Question: Wouldn't this introduce a mercury poison risk to the environment during disposal?

Congress:Member:Michael Riversong writes: "Mercury switches are commonly used to handle interruptions from abrupt changes in overall position, like tipping over. These are typically found at Grainger's in many price ranges and configurations."


Test the Core System

Before you worry about dressing out the cabinent, you should first connect the HHO generator to the catalytic converter (with entry insulation) to see how it works.

Adjust the output rate to see how high you can go before you start getting backflash happening (which marks the high limit).

Let it run for a few hours

see if the system is stable

see how much heat is produced

Before we assemble the components in the cabinet, I would like to run a test to see what level of energy efficiency we are achieving with this combination of items. We have a 13.75 gallon tub that we can use to submerge the catalytic converter in to take some rough calorimetric measurements of the heat gain versus Watt input to make the HHO gas. I'm guessing we can get an accuracy of a margin of error of less than 10%. I've been told that running it long enough to get about a 20 ºC change in temperature of the water -- staying away from the boiling point (phase change...) would be the best way to do this.

Free Energy Blog:2014:04:01 - I hope you'll see that I've given a strong rebuttal to the claim that the clamp-on amp meter results should be thrown out because the meter was on the wrong setting. I think I've made a strong case that our results point to anomalous heat. (Free Energy Blog April 1, 2014)

Conventional electrolysis and fuel cell limits combined give a 80% 60% efficiency maximum, suggests an anomalous effect. (Free Energy Blog March 31, 2014)

Free Energy Blog:2014:03:29 - "This is the first 'dry run' assembly of the water-bath calorimeter I am building - a build sponsored by the members of the E-Cat World forum. The idea is to test the oft-made but essentially unproven claim that catalytic re-combination of HHO" (Free Energy Blog March 29, 2014)

Latest: Latest: Directory:Nuclear > Directory:Hydroxy or HHO Injection Systems / Directory:Cold Fusion > OS:Justin Church's H-Cat > OS:H-Cat Calorimetry - The testing of an H-Cat system should be relatively easy: energy in (electrolysis to create the HHO gas) versus energy out (heat emitted from the catalytic converter), both converted to joules for comparison. This can be done in a simple water bath. (PESWiki March 24, 2014)

Latest / There was an error working with the wiki: Code[1] / Directory:Cold Fusion > OS:Justin Church's H-Cat > OS:Sterling Allan's H-Cat Heater Design - I propose to 1) remove the outer insulation layer from the catalytic converter... and 2) replace it with a metal sleeve that leaves a gap of about 1/16 inch between the matrix and the exterior. That way most of the gas flows along the surface of the matrix, along the exterior, where you want the heat. (PESWiki March 15, 2014)
