Best hho dry cell design

Originally this page was designed to keep updates on how people were installing hho kits around the country in 2008 and 2009. It is just amazing how the minds of the mass public can be manipulated.
Gas is on the average much higher now and everyone has been conditioned to accept that as normal.
Update (8/2013): All our HHO Dry Cells are Now 3/8" fittings at "high low" positions, and we have released our new 13 and 25 plate HHO dry cell generators. In time we will update all images to reflect the changes in our Superior design of hho dry cell generator.
Hydrogen boosts Beloit -- Adding HHO dry cells to City Cars and Trucks

Dan Lutz was so captivated by hydrogen-on-demand technology that he spent months tinkering in his garage to construct a hydrogen booster to help increase the gas mileage on his pickup truck.
"I just thought, 'Man, this is amazing,'" he said. "I wanted to see if this really worked."
The modest unit—fashioned from stainless steel electrical wall plates, PVC pipe and plastic tubing—produced impressive results: The pickup truck went from 11 miles per gallon to 22 miles per gallon during a 70-mile test drive.
Lutz was floored.
"I was like, 'Oh my God, I can't believe this. This really works,'" he said.
Lutz, the fleet manager for the public works department, took the idea to work.
"I just said, 'What do you think about running your fleet on water?'" he said.
It didn't take much to convince the department to dig further into hydrogen technology.

"The first thing out of my mouth was, 'Let's try it,'" Walsh said. "We take calculated risks. I know that's different for most municipal government, but the city is in a situation where if we don't take calculated risks to be as efficient and cost-effective as we can, we'd be in trouble."
The department started in November by installing wet cell hydrogen units from Oklahoma-based Protium Fuel Systems on three vehicles—a large pickup truck, a garbage truck and a recycling truck.
But it quickly ran into trouble with the units, forcing the department's mechanics to redesign the boosters so they worked, Lutz said. The three vehicles still are running on those rebuilt boosters.
Hydrogen-on-demand technology has changed dramatically in the last several months, and the department wanted to give new-and-improved boosters a shot, Lutz said.
The department last month installed hydrogen dry cell units from California-based L2 Hybrids on two more vehicles—a police squad car and a small pickup truck.
While the department isn't having much trouble with the new units, it's still working out the kinks, Lutz said.

'Let's try it'

Water into fuel ?

So how does hydrogen-on-demand technology work?

The units the public works department installed produce hydrogen as needed through the electrolysis of water.

Under the hood, a plastic reservoir is filled with distilled water. The water circulates through the booster, (HHO Dry Cell) where an electric current breaks it into hydrogen and oxygen gas. The hho gas then is injected into the engine to help gasoline burn more efficiently.

And how does hydrogen improve gas mileage?

Unleaded gasoline engines are only about 20 percent efficient. That means the engine is burning only one-fifth of the gasoline pumped into the vehicle; the rest leaves as exhaust through the tailpipe, Lutz said.

But the introduction of hydrogen makes engines burn 100 percent efficient. Hydrogen is a volatile gas, and when it's added to the combustion cycle, it forces everything to burn. That means more miles per gallon and fewer emissions, Lutz said.

'Imagine the impact'

In 2008, the public works department spent $365,529 for diesel fuel and $344,730 for unleaded fuel for its 330-vehicle fleet—a total of $710,259 in fuel costs.

Assuming the department sees a 25 percent savings using hydrogen-on-demand technology on 163 vehicles—about half the fleet of garbage trucks, recycling trucks and pickup trucks—the department could save $177,565 in a year.

Walsh said the estimate is "very conservative" because vehicles with hydrogen boosters typically see an increase in gas mileage between 20 and 50 percent and higher.

The public works department already has seen its small pickup truck go from 14 to 22 mpg—a 57 percent increase. The truck has even gotten gas mileage as high as 31 mpg—a whopping 121 percent increase. And its large pickup truck has gone from 12 to 20 mpg—a 67 percent increase.

Each hydrogen-on-demand unit costs $1,700. Installation for one vehicle costs $400. Retrofitting half the fleet would cost $421,197. (Check out our HHO Dry Cell Kits ) - a Fraction of this.

Based on the estimated 25 percent savings, the hydrogen boosters would pay for themselves within about 2 1/2 years.

"You can imagine the impact this can have on local government, state government, federal government for saving money," Walsh said.

City Manager Larry Arft said the city is slated to get federal stimulus money, which could help pay for the project. But the department is relying on test results to show the money would be well spent on installing hydrogen-on-demand units in the department's vehicles, he said.

"We know the basic technology works, but the issue is, is it practical," he said. "Can it be used realistically?"

Walsh said the department is continuing to put the five vehicles through tests. The department will evaluate the results in about three months, and if the results are favorable, hydrogen boosters would be installed in half of the department's vehicles, she said.

It makes more sense to "retrofit" the vehicles with hydrogen-on-demand systems than to replace the entire fleet with hybrid vehicles, she said.

Gas is now up to almost $3.00 in Southern Ca. Those friends and customers of mine that installed our Hydrogen on Demand systems have saved hundreds this summer and can travel where ever they want.
Here is a recent letter from Bob Boyce and some test on a particular Hydrogen on Demand system.
We are not publishing this to knock this manufacturer but to give you a heads up on what does and does not work when building these large HHO generators.

I am sad to report that I can no longer endorse the products now manufactured by Premelters Inc, and sold by Pre combustion Technologies Inc. The products are no longer manufactured to my plate preparation specification, and do not perform even half as well as the products I had endorsed in the past.

As a few people know, I had to leave Florida mid-April due to worsening health issues with my wife. She needed to get back home to her doctors. And I needed a break from the growing tension.

Just prior to me leaving FL, there was a recommendation to try electropolished plates in a few test units. Even though I already knew what the outcome would be, I knew that there would be those that questioned my judgment on this unless they could see for themselves. When initial testing confirmed that performance was greatly impaired, I had hoped that would be the end of it. Unfortunately, that was not the case. Test results were mis-interpreted due to a lack of understanding of important factors by those making the decisions.

In the interest of faster production, the plate preparation procedure that makes my designs so efficient, has been replaced with the electropolished plates. As many know, electropolished plates do not need to be cleansed or conditioned, BUT they also have serious drawbacks. Electropolished plates require MORE voltage to push a given current, they DO NOT improve in efficiency with use, and they DO NOT produce the same quality of hydroxy gas. The result is very poor efficiency, MUCH higher operating temperature, excess water vapor production, and the hydrogen portion of the gas is all parahydrogen instead of the 30% parahydrogen and 70% orthohydrogen blend that works.

Understanding the relationship of applied voltage vs current required is very important. To just look at amps and not factor voltage or cell configuration causes so many to totally miss the mark. With all other factors being equal, if a cell is configured for nominal 24 volts, then obviously the current required SHOULD be half that as compared to a cell configured for nominal 12 volts for the same level of gas output. When one looks at gas production from a 24V configured cell and compares that to gas production of a 12V configured cell at the same current, one can be tricked into thinking that 24V cell is better, because the voltage factor is not considered. So when one sees 7.5 LPM from a 24V configured cell running at 52.5A, then one MUST compare that against a 12V configured cell running at half the voltage and at 105A. To conclude that the 24V configured cell is doing better than the established average "standard" of 10A per 1 LPM is ignoring the fact that at 24V, the new average "standard" would become 5A per 1 LPM. Therefore, it should be logical that 7.5 LPM is well below the average mark for a cell running at over 31V @ 52.5A, WELL in excess of the nominal 24V. Using the same plate technology with a 12V configuration requires voltage even higher than a vehicular electrical system is capable of delivering, in order to pass full rated current. This limits the maximum amount of current that can pass, and increases the waste heat factor by a very large margin. So large in fact, that it increases the cell operating temperature by 50 F in a side by side test of otherwise identical units operating at identical current.

Despite the continued positive spin being placed upon product performance by the manufacturer, all subsequent testing by the dealerships have proven that the new units are no longer performing as claimed. Higher operating temperature, no fuel economy gains, and no improvement in vehicle emissions. In fact, quite the opposite has occurred in most cases.  If you are a dealer or customer with an older system, DO NOT send it back for replacement. The only systems still working as designed are those older systems! Flush out the system very well and do a lengthy cleanse procedure with 5 micron water filter(s) inline with the cell output port(s). This will allow the contamination to be eliminated, and allow the system to be able to perform as designed.

Bob Boyce

If you don't know who Bob Boyce is. Do some Hydroxy research on this Hydrogen on demand site and all over the internet. He is no doubt one of the leading authority's on building HHO generators.

Who told you you can't make enough Hydroxy to run a car 100%? Bob has to say that so THEY don't kill him, or put him in jail for doing it. It is history that he had a car running 60 mph up on jacks stands 100% on Hydroxy generated off of the Alternator alone. They arrested him in FL for EPA violations because an informant lied and said they were running the car down the road with those modifications. Think how criminal it is that they would arrest him instead of giving him a Nobel Prize! The people should take action to remove every official involved and enact laws specifically aiding such research. In Mississippi, if I remember correctly you don't even have to buy a tag for a research vehicle. 

This is a rather long Hydrogen on Demand Discussion but a must see for anyone studying HHo (hydroxy gas)

Bob Boyce is interviewed by Hollywood Filmmaker and New Energy Congress adviser, Chris Patton, of Zero Point Films. This is an exclusive uncut version filmed in 2006. Boyce is one of the leaders in the hydroxy/electrolyzer (hho generator) technology in which electrolysis is used on-board to create hho gas from water to inject into the air intake of a vehicle to increase mileage. He has been open sourcing his plans for years. He participated in the Hydroxy Booster Rally from DC to the Florida Keys and back in April 2008 using variations of his hydroxy electrolyzer systems. Chris Patton, who is completing a documentary on various breakthrough energy technologies, gave Pure Energy Systems (PES) Network permission to run this uncut version.

------------- Resonance coupled with the transformation of Tranverse waves converted into longitudinal waves. I'd actually think that the latter part is the most important but as Bob said in the posted google video interview with him: paraphrasing "...it's a combination of factors. You won't get the effect that you are looking for if you are missing certain factors. Period.". I highly recommend every one look up the interview. 

HHOHHU has developed a self-contained home heating unit that utilizes water as its fuel. Electrolysis is used to split the water molecule into hydrogen and oxygen, which is burned to generate the heat. They say their first version of the HHOHHU draws ~450 Watts and can heat 1,000 square feet.

They sell plans for the system to enable people to build one of these from parts available from the local hardware store.

A patent was filed in January 2009, just prior to making the plans available. The company is quasi open sourcing the design for further development. Devices can be made for personal use, but commercial development needs to be licensed with the company. A kit is coming soon which will result in a unit 20x20x8 inches that will heat 1,000 square feet. Meanwhile, they also have some of they key components, such as the two HHO cells involved, available for perches now. They are also working on gearing up to mass produce these. They are also working on a hybrid furnace conversion system that could run along side existing furnaces to augment them.

They say they have sold hundreds of copies of the plans, and have not had any refund requests; with several known successful replications personally witnessed. While their plans describe how to make every component, they do make some of the more difficult components available for sale, such as the two cells, the case, the flash arrester, and the heat sinks.

The savings on energy is supposedly enough to pay for the materials within as little as three months. Their electrolysis system draws from the best hydroxy technology they've seen, each cell producing 2 liters per minute, at 12.5 amps and 12 volts. The key to their system is the heat exchanger that extracts the heat from the very unusual flame that has been shown to be able to melt tungsten in just a few seconds. They also put to use the heat generated from the power controller, the electrolysis, and even the fan.

As of Feb. 21, 2009, PES Network, Inc. is in discussion with HHOHHU to provide PESWiki as the preferred destination for coordinating the open sourcing portion of this technology.

Hydrogen Hybrid Technologies Incorporated (HHT) is moving into the Korean market with their on-demand Hydrogen Fuel Injection (HFI) system. Because of recent greenhouse gas and emissions legislation by the Korean government, involving transport truck pollution around the capital city of Seoul, trucking companies are looking for ways to reduce their environmental footprint.

The Korean government also has a list of accepted vendors that trucking companies can pick from in order to cut down on emissions. HHT is in testing now with their hydrogen-on-demand system with the Korean government to prove by the end of 2007, that they too should be on that list. If accepted into the program, HHT estimates they will capture a market of well over 100,000 trucks.

HHT offers its HFI LX Series for large transport trucks and a smaller HFI SX Series for small passenger vehicles such as pickup trucks. The HFI LX Series uses distilled water that is electrolyzed and injected into the intake manifold of the diesel-powered truck. The distilled water lasts for 65 hours of operation between refills. HHT also offers an on-board digital controller, which monitors the on-demand system via satellite and can even offer software updates remotely as well.

The HFI SX Series is a smaller hydrogen on demand unit that has been sold commercially since 2005. The unit is more compact than the LX model and can be placed in the bed of the truck, such as in a toolbox that is optional for many vehicles or can be added on.

Hydrogen Hybrid Technologies is based in Ontario, Canada and is selling its Hydrogen-on-demand systems worldwide. The HFI systems are geared towards electrolyzing water, injecting the hydrogen and oxygen in to the combustion chamber displacing some of the diesel fuel (which means using less fuel) and making the engine burn cleaner, thus reducing emissions.

Check this out Hydrogen on Demand" Home Heaters

Sovereign Energy Solutions has developed a home heating unit that utilizes water as its fuel. Electrolysis is used to split the water molecule into hydrogen and oxygen (hydroxy gas), which is burned to generate the heat. The unit pulls 800 Watts and puts out roughly 30,000 BTU. (Usually 800 watt-hour is equivilant to 2730 BTUs). As of around the week of Feb. 15, 2009, they began selling plans for their system. The retail cost of the components required to build the unit is around $600. The savings on energy is projected to be enough to pay for the materials within as little as three months.

They are working on a kit as well as a hybrid furnace conversion system that could run alongside existing furnaces to augment them. They also intend to produce these as completed units once they complete the UL certification process.

The electrolyzer is based on the same technology they used to develop the "Rev 3" on-board hydrogen-boosting unit for vehicles, a system they have been selling on their hydrogen on demand site.

The key to their home heater system is the heat exchanger that extracts the heat from the very unusual flame that is able to melt tungsten in just a few seconds. Because the "exhaust" is water vapor, the unit ads humidity to the air, reducing the amount of heat needed.

As for Feb. 27, 2009, the company had built three heater units. The process is yet too young to have had time to ascertain whether the plans are adequate for someone to build a working unit from the plans alone; but that has been the company's objective.

What an awesome accomplishment in the Hydrogen on Demand movement.
This is the stuff that researchers in the use of HHO gas to assist or power your every day gas or diesel motor love to read about.
This to me proofs beyond a doubt that if we keep up the Hydrogen on Demand movement we will all some day be burning hho gas in our vehicles.

Posted 1/17/09 by C. Michael Couch for Pure Energy Systems News
Grad student, Jake Wall, fitted a scooter with a Bob Boyce like electrolysis unit and was able to run the scooter (in the garage) on just the hydrogen-oxygen mixture, using half the energy input the engine normally requires.
A new milestone has been reached in the Hydroxy field. Using an 8 plate, 7 Cell, Bob Boyce style, Hydroxy generator; Jake Wall (screename Jakerwall), an Idaho Biology and Agriculture Engineering grad student, has succeeded in idling and accelerating a 2002 Honda Metropolitan, 49 cc. ~4HP Internal Combustion Engine scooter, on 100 % Hydroxy alone.
( These guys won't use the term HHO in their articles because there is, believe it or not a patent pending on the term "HHO")

Jake would like to do the road tests on a Honda Rukus that has the same engine but would be better for mounting the Hydrogen on Demand as the cells and batteries do take a bit of room. "I think that two cells and two deep cycle batteries, along with a PWM (Pulse Width Modulator) that could be controlled by the throttle position sensor would allow you to drive the scooter," the young engineer said in an email interview.

He gets excited thinking that after the initial road tests were done, modifying the scooter's charging system for the load, and using a resonance system to reduce the electrical input required to make the needed volume of gas, would give you a "self-sustaining water scooter", presuming the system is somehow harnessing energy from nature.

He estimates that the scooter takes about 1.5 liters/minute of Hydroxy to idle the engine and his current test system maxes out at about 5 liters/minute. He reasons that approximately 10 liters/minute would provide enough flow rate for "all driving conditions". Mr. Wall writes, "I bet it would even run better than gasoline."

His cell of eight 316 Stainless plates was configured as a "sealed series cell using spacers from Ed Holdgate". Mr. Holdgate is a machinist who has been working very closely with Bob Boyce the current Guru of Hydroxy and forum owner of the famous Hydroxy Yahoo!Group. Jake uses about 16 Volts at 50 Amps (800 Watts) to rev the engine for 30 seconds or so. Idling only requires 14 Volts at 25 Amps (350 Watts). This is verified by readings visible on the various videos he has posted to You tube.HHO Generator

EPA update, another example of what is wrong

Are we who use HHO gas injected into our engines BREAKING THE LAW. Here is what the (EPA) U.S. Environmental Protection Agency has to say about HHO GAS and Hydrogen on Demand 40 CFR Part 85 Subpart F requires certification of after market fuel conversions to avoid violating the anti-tampering provisions in Section 203(a) of the Clean Air Act. EPA considers supplemental fuel systems such as an on-demand supply of hydrogen to be a type of fuel switching. You will likely find many types of fuel conversion kits on the web, including hydrogen on demand kits. Most all are illegal and our office generally refers these to our Enforcement Office when they are brought to our intention.

People this is wrong. I for one have proof with two separate vehicles we tested and they absolutely did get much cleaner results at the smog test. Why would the EPA not allow Hydrogen on Demand ADDED if it proofs to clean up the emissions.  The EPA, and others who have never installed a hydrogen on demand system are misguided. These retrofit hho generators and Hydrogen on Demand  systems are merely a supplement, they do not replace gasoline and are not intended to, it's an additive, not a switching of fuel type like the EPA says. The people who use this HHO technology must stand up. I am compiling a massive list of proven results that adding HHO GAS to your gas or diesel vehicle does reduce harmful emissions, if you can offer any proof please contact me.

Hydrogen on Demand could have been in use a Long Time Ago

I get real frustrated with the experts/critics/naysayers who "have all the answers", when in reality they don't even know the question. For the record, Hydrogen fuel enhancement was first researched by the Jet Propulsion Labs of the California Institute of Technology in 1974. John Houseman and D.J. Cerini investigated the use of hydrogen technology showing interesting results in emissions and gas mileage. The S. Korean government has mandated that over 100,000 transport trucks be fitted with HHO generators to cut down on pollution. The U. S. Department of Energy lists an HHO generator manufacturer on its website. Another manufacturer has its application in with the California Air Resources Board (CARB). And, the provincial Canadian government is funding the hydrogen fuel injection units that will be placed in the school buses to increase fuel mileage. Finally, the State of Arizona tested for 5 years, on everything from a Ranger pickup to a 14 L Freight liner and found "significant" results (As in ZERO % Particulates!) with Hydrogen induction.
Bob Boyce gets Fed Up
Here is a recent post from Bob on Working water car. Bob is the king of Hydrogen on demand and has made great leaps for all of us in hydrogen on demand research and HHO gas production. I for one do not want to see him shut down the water car comments. If you agree go to the water car group and voice your opinion.
Here is what Bob said about the Pulse Width Modulator - PWM3G
Those instructions are wrong. Someone probably tried applying the PWM3F instructions to the PWM3G. The result is some good info and some bad info, as they are only similar in the pulse generation stages. The output stages are totally different. Those jumpers on the PWM3G are only put on for testing, during use they are removed so that the LEDs are disconnected and will not be destroyed in operation. Installing those jumpers do not disable the channels, they only enable the LEDs.

Please make sure these corrections get made to the instructions, as I am done with providing open source support. I've had quite enough of being bashed and accused of stupid crap by ignorant members of the on line community. I tolerated this abuse in return for what? Well that time is over, as I will no longer accept being abused for free. Just remember, before accepting advice from other people. Do they really know what the hell they are talking about or doing, are they just guessing, or are they pushing their own agenda?

Other Hydroxy News

In Hydroxy related news, a youtube video named Helix 1.7 has created a big buzz in the Electrolyzer community producing a tremendous amount of Hydroxy with 12V at 8 amps input or 96 watts.

Reports of overunity operation have not been document as of yet.  What remains is for someone to measure the energy output from the use of the Hydroxy generated, to compare with the 96 watt input.  Observers suspect that the apparently high Hydroxy output from multiple Helix 1.7 cells could power a car.

The single Helix cell seems to produce enough gas to power a lawnmower engine if the waste spark can be eliminated and the quality of the Hydroxy being produced is high in mon-atomic hydrogen atoms.  No one has reported trying to run a lawnmower or other small motor on the Helix cell output as yet.  A small four cycle engine would be an ideal test platform to verify the quality of the Hydroxy it produces.  Researchers will keep a close eye on this Hydrogen on demand Youtube as they hope for further developments on the Helix 1.7 cell and replications of the Bob Boyce Electrolyzer.
