What Reall is The Best Catalyst For HHO Dry Cells ?

Hi People, sorry I haven’t posted lately, been busy setting up distribution of our hho dry cell design over seas.
Do you guys here in the USA realize they are spending $6.00 + a gallon for gasoline ?
Anyway I wrote an article on Koh for your hho dry cell a while back and some interesting comments came up –
Potassium carbonate for catalyst – Now it is my turn to ask the questions — is anyone getting good results without adding lye ?
I have a chemist looking for a less caustic solution than KOH but have not located anything yet.
Would love to here from you guys on this one. Best hho dry cell design

Over Heating My HHO Dry Cell (hho drycell )

Some More Basic Hydrogen on Demand Tips.

Why Does my HHO Dry Cell Heat Up ?
You want to check your water level every 3 hours.  You are burning
‘water for fuel”, so the water level will diminish. What happens is as the water turns into HHO gas and burned by the vehicle the water level goes down. The problem with this is that the cell then has more room in it for hot HHO / water mix and the catalyst you are using becomes more concentrated. To insure long life out of your fuel cell always keep your reservoir filled to capacity as per the instructions.  There are a lot of other reasons why your HHO drycell might over heat but we found this to be most common, we will be posting a list here or you can find an answer to most questions here on our Hydrogen on Demand system site HHO2u.com

Hho – THE TRUTH about HYDROGEN generators and Water4Gas

The Truth About The Hydrogen Generator or HHO Generators.
Are Hydrogen Conversion Kits a Scam? How to Build a Hydrogen Generator
DIY HHO Gas Conversion Kits Homemade Hydrogen Generator Plans.

The truth about the Hydrogen Generator, or HHO Generators, as it is commonly called.

The Hydrogen Generator, or HHO Generator, is one of the most searched terms on the Internet today. It’s no wonder the way gas prices shot up and then down.(we know they won’t stay down for long)
Everyone is looking for a way to save gas, even if it’s by a process of turning water into a burnable fuel.
Call it what you like Browns gas, hydroxy, HHO ect.
I found this ridiculous article by someone trying to push their version of a hydrogen generator by making claims that plastic (abs) is better to cook hho gas than glass, this guy needs to do some studying before he starts knocking the water4gas type generators. ABS WILL MELT

I know first hand that the water4gas type Hydrogen Generator does indeed work very well and are very safe, unless of course you want to play basket ball with it. We have built and supplied many of these to our customers and every one of them is satisfied. Testimonials at HHO2U.com

This same guy says he is an expert on HHO  production because he “made some bubbles and lit them with a lighter”  Wee that a plus, but we did that years ago “just to see if it was real”.

There is a real problem out there with myths and misinformation about these Hydrogen Generators. So I will share the facts with my readers about the Hydrogen Generator, HHO Generator.

Let me take this opportunity to apologize to my readers, lately I have been pushing my website on this blog and forgot why my readers are here  — Accurate information on Hydrogen on demand. We will continue to bring you the most accurate honest information on  this subject.

Please feel free to join in on the discussions, give your input, share your ideas and experiences. Lets get to the bottom of all the hype about the Hydrogen Fuel Cell.

Improving Gas Mileage Economy
Simple Free Ways To Improve Gas Mileage or Kilometers Per Litre
Have you asked yourself how do I increase gas mileage?

If your looking into gas savings or saving  gas by use of devices that produce HHO or ‘browns gas”, some times called Hydrogen on Demand systems.
Make sure your car is getting the best mpg or kilometers per litre kpl. with these free tips first.

With these basic tips you can increase your fuel economy and also improve your ride and prolong you cars life.

By properly tuning  your vehicle you can gain about 4%  better gas mileage.

A faulty oxygen sensor when fixed can improve your gas mileage up to 40%.

Replace air filters regularly this can improve your gas mileage or kilometers per litre up to 10%.
Fuel Economy Savings: up to 10%

Keep Tires Properly Inflated. This is not only a gas savings issues, up to 3% better gas mileage but also will increase the life of your tires
and give you a safer more confortable ride.

Just by keeping your motor oil clean by changing it every 3000 miles and always use the recommended grade as suggested by your
manufacturer or a high grade synthetic you can Benefit a  1-2% increase in your miles per gallon or kilometers per litre.

After you have done everything according to these Tips, your maintenance manual and your mechanic to increase gas mileage
You can now gain an additional 15% – 50% by adding  HHO by HHO2U.



What is a Map Sensor?

A manifold absolute pressure sensor (MAP) is one of the sensors used in an internal combustion engine’s electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine’s electronic control unit (ECU). This is necessary to calculate air density and determine the engine’s air mass flow rate, which in turn is used to calculate the appropriate fuel flow. (See stoichiometry.)

How much Water is Used?

Very little. You could drive many weeks without having to add more. We advise to add distilled water once every week or two to ensure maximum gas production. If you drive the average of 2,000 miles per month, only 1 Gallon of distilled water, costing about $1 at grocery stores, is consumed in about 8 months (in a single cell system). If you want to make your own distilled water, units are out there for around $100, or you can find simple plans online to build one.

How Can I Measure the Exact Savings?

Digitally: 1) The most popular and precise option, simply mount a device called a Scan Gauge on your dash. This connects to the vehicle’s Onboard Diagnostic System and reports your mileage clearly! We offer these for $200 if you would like one. You can see this in action on the first Customer Experiences video. The only limitation is that the device will not work on vehicles older than 1996, so you will have to choose another option below.

2) There is also a device that connects to your Palm Pilot or Laptop and provides sophisticated diagnostic information. It is called Auterra Dyno-Scan, and has the advantage of keeping records of your performance, including horsepower, torque, gear ratios, top speeds, etc, and will map the information for you over time.

Manually: Online there are various free calculators that will do the math for you once you plug in the numbers.
This is accually fairly accurate:

1. Go to the gas station and fill up the fuel tank.
2. Record the mileage, before even pulling away from the pump. We will call this Mileage A.
3. Drive normally until the tank is less than half full.
4. Fill up the tank again (preferably at the same station using the same pump as pumps may be calibrated differently). This time, pay attention to how many gallons it takes to fill up the tank and record this number.
5. Record the mileage again, just like before. We will call this Mileage B.
6. Subtract Mileage A from Mileage B. This will give you the number of miles you drove since your last fill-up.
7. Divide your answer by the number of gallons it took to fill up your tank. This will give you your vehicle’s MPG.
8. Repeat this test again, this time with the Water Fuel System installed and operating.
9. To determine the percentage increase, divide this number by the your vehicle’s original MPG, subtract 1 and multiply by 100.

In Equation form:

Fuel Economy (MPG) = New odometer reading – Old odometer reading
Gallons of fuel to refill tank

MPG gain (in %) = New MPG x 100 -1
Original MPG


Every one or two months remove the HHO Generator from it’s holder and clean it with a toothbrush and tap water. Make sure that the engine is off and the Generator is cool before servicing. For extra safety, also remove the fuse to the battery connection before servicing.

Check the water level about every gas fill up, keep it about 1″- 1 1/2″ from the lid.You must also add a small amount of standard baking soda when you add more distilled water. This acts as an electrolyte, helping the reaction to occur optimally. You only need 2 teaspoons of this per 1 gallon of distilled water. Premix it and keep a jug in your trunk or garage.

Will the HHO injection Damage my Vehicle?

No way! It will improve the health of your engine by cleaning it every day. Unburnt fuel deposits that build up in your engine will be removed, reducing wear and tear and increasing performance. There will be no rust from the Hydroxygen. To power the device the battery and alternator are not overworked by any stretch of the imagination. The Water Fuel System requires a very small amount of energy to operate: 1-3 amps, much less than your car stereo! Dual Cells draw 2-4 amps, while 6 Cell Packs draw only 5-7 amps. A 15 amp fuse protects the setup from drawing too much power. ( THIS ANSWER IS FOR THE WATER4GAS TYPE UNITS) NOT A GIANT 12″ X 11″ TWENTY PLATE UNIT.


Emissions are largely the result of unburned fuel. Since more of the fuel is completely combusted, these are reduced, to the same degree that your mileage is increased. The result of splitting apart the water is water vapor and oxygen, two totally harmless substances that may actually help to clean the environment. This significant reduction in emissions will help to reduce the harmful effects of poisonous pollution and climate change.

Performance Increase & Changes in Operation?

With this System more of your primary fuel will be completely burned, smoothing out and improving overall operation. You will almost immediately notice a significant reduction in engine noise, as a more complete combustion helps the engine to cycle correctly. For a period of about one month the engine will continue to remove built up carbon deposits resulting from unburnt fuel, further increasing your performance & mileage and reducing your emissions. Your valves and pistons, etc, will be free to operate smoothly, thereby reducing wear and tear. The acceleration and horsepower will increase as the engine will be operating more efficiently. Be aware of this as you may not have to push the pedal as hard as usual to take off!
