1. Can You Explain in Simple Terms How this Works?

Hydrogen Generators, like the type we sell here, are based on the patented discoveries of a William Rhodes in the early 60's and then advanced 12 years later by a Professor Yull Brown in the 70's (who spent almost $30 million over his lifetime trying to get Brown's Gas into the mainstream). Both men developed a special type of "Single Cell" electrolyzer that extracted hydrogen and oxygen out of water, but unlike the common practice of separating the two gases, they realized you could actually allow them to combine into one, energetic, very combustible gas.

This gas is created "On Demand", only when engine is running. Nothing is compressed or stored anywhere - it is used immediately as it is made, making it quite safe. The gas is filtered and injected into the air intake of the car, where it is drawn in with the regular air and fuel of the vehicle. It then acts as a "Combustion Catalyst" causing the fuel to burn more quickly and completely. This results in a more efficient engine cycle, reduces emissions, adds pep to the accelerator, and increases the mileage on average from 20-50%. Most of the general public have still never heard of it and are surprised upon its discovery. To read the full explanation go here.

2. Is this the same thing as a Fuel Cell?

No. A Fuel Cell uses hydrogen and oxygen fed into it, to create electrical energy, generally used to charge a battery or run an electric motor. The hydrogen comes from another outside source - either a special filling station, or maybe a large electrolyzer in home. Some fuel cells create hydrogen chemically from natural gas, but you still need to fill up with natural gas, or find a station that makes hydrogen.

HHO kits, on the other hand, use the extra electricity from the alternator/battery to Create Hydrogen-Oxygen gases from water, which are then fed into a stock engine (no modifications needed). It is only creating hydrogen when the engine is running - no storage needed. No infrastructure needed. No finding a filling station that pumps hydrogen. All you do is top off the reservoir with water once a month.

3. Do the instructions show me how to install everything? I am not a mechanic.

Yes, you receive a well illustrated manual (download and print). Our manuals are very clearly illustrated and can be understood even by the novice installer. You also get free tech support during the process. You do not have to be a mechanic or electrician to install our kits, but it does help if you are handy with your hands.


4. Will the HHO Generators work on both Fuel Injection and Carbureted engines?

Yes! Carbureted engines need no electronic measures, unless they have a simple O2 sensor in the exhaust manifold. Fuel injected engines need an electronic measure. If the car is 1996 or newer (OBD2) has fuel injection or TBI (throttle Body Injection), you will need either an EFIE for gasoline, or a Diesel Tuner. for diesel engines. You can find both of those here: EFIE for HHO KITS


5. What if I have problems installing the kit or afterwards - is there any tech support?

Yes. You can contact us anytime by email; we will reply asap. Or contact us via phone at 1-925-427-1000. You can also use our Live Chat feature during normal business hours.

6. Is there any kind of guarantee that comes with my HHO Kit?

Yes there is a Five Year Warranty(800 Series) and a 30 Day return policy on our kits and accessories.You must check all products within 30 days of receipt to make sure none are broken or non-functioning. If your kit does not fit or you decide you cannot do the installation, return it within 30 days for a refund. Go here for our warranty and return policies.

7. What is the O2 Sensor and why does it matter?

The O2 sensor is a small measuring device about the size of thick spark plug with thin wires coming out the end. It is always located ON the exhaust pipe. Older models (OBD1) usually just have one right before the catalytic converter, newer models have 2, 3, or 4 depending on size of engine. Small engines have 1 or 2, big V-8 engines will have 4. They measure the amount of O2 (oxygen) coming out of the engine and the sensor then sends a signal to the cars computer to either INCREASE the amount of fuel it's injecting into the engine, or DECREASE it, depending on the level.

The cars computer has only been programmed with information regarding regular fuels (whatever it was designed for). When you make an efficient HHO generator, you are injecting a LOT more oxygen in to the engine (which is actually GOOD, but the computer thinks something is wrong). The computer thinks the engine isn't working properly and adds more fuel to burn the extra oxygen. If you don't add an EFIE or other electronic device, you could actually lose mileage with an HHO generator.

8. What is the best method for running my HHO Generator Kit?

After installation, fill with distilled water mixed with the electrolyte as instructed in our manual included with the kits. Make sure you wire it into the ignition switch so it comes on only when engine is running. Our hho kits like the 18-30 amp range and most cars have no problem running at that rate. Most users achieve a 20% - 50% fuel savings on average.

9. What do I do to protect the HHO Generator during cold weather?

The electrolyte concentration helps for normal areas of the country, but if you have extended freezing, you need to use either an additive or more electrolyte and a PWM controller. We can help you set it up to prevent freezing, even down to the -30 or -40 degree mark. Contact us for help on what you need to winterize properly.

10. What if I want to move the HHO Generator another vehicle?

You can swap vehicles. The efie (for the engine sensors) can be swapped in most cars as long as they are the same type (narrow band or wide band). Contact us if you need help.

11. How often do I need to check the water?

Depending on driving habits, most cars use between .5 to one liter of water every couple weeks. Our new 800 series cells use even LESS water depending on how you set it up - the lower the amps, the less water you use. Check when you fill up your tank for the first month- just to get a good idea of water use.

12. Do Your Kits Work With LPG (Liquid Propane Gas) or CNG (Compressed Natural Gas)

Yes- our kits have shown significant gains in vehicles with those conversions on them. Not only do they help with power, they clean emissions even further and extend mileage. One of our customers in the UK put one on his LPG conversion and went from 1000 kilometers per 130 liter tank, to 1500+ kilometers per tank. He dropped his costs from .12 per mile to only .06 per mile.

13. Will I have to replace my Alternator or will it hurt my battery?

Most alternators keep up no problem. Our generators like to run in the 18-30 amp range. It may seem like a lot, but it is still less than a 500 watt stereo amplifier...
The modern cars are equipped with heavier duty alternators because of consumer options.The only time we have had trouble is the really old cars like the 1965 Mustangs that only had 35 amp alternators from the factory. But most modern cars keep up without any problem. With many thousands of kits sold around the world, we have never had a battery go bad, or alternator burn out as a result of using our kits. Everyone on our mileage results chart were running their kits at the recommended HHO Kits Direct Mileage Results

14. Is it possible to run the vehicle on just HHO alone without any other fuel?

First of all- let me dispel a common misconception: you cannot run a car on water only. If anyone tries to sell you something that they claim does that, run the other way! Almost every other month a new "claim" is made that this person or that has discovered how to run their vehicle on water only, but further investigation proves these claims false and unverified. One example is the popular youtube video of a man claiming his Dodge ram truck ran only on water. It is no coincidence that this mans name was "Fast Freddy". Every one of his claims has been false. Only one man seems to have had that distinction - Stanley Meyer. He was poisoned before the product could make it to the market, and although many of us are researching trying to duplicate his work, No One has been able to do it yet. So do not get suckered or caught up in false claims. Better to get at least 20-50% increase now, than nothing at all!

15. Is it dangerous to have hydrogen gas under my hood?

Not any more dangerous than having gasoline under there. Like gasoline, Hydrogen gas is explosive, which is why it helps increase your mileage. Unlike gasoline, you make only what you need (Hydrogen on demand), so you're not storing 20-30 gallons of it under the back seat like gasoline or diesel. You only have a tiny amount being stored in the hoses as it is drawn into the engine. Treat it with the same respect as you would gasoline, and you'll be fine. We have had three reported incidents from our customers over the years, of their cars being totaled in a front end collision, and the generator was destroyed, but no flames, no explosion- nothing happened other than the destruction of the units. Our HHO kits are much Safer than regular "hydrogen only" units because there are no high pressure storage tanks that could explode

16. What is the difference between a wet cell, dry cell and your hybrid cells?

The difference between wet and dry cells is that the stainless steel plate stack in a wet cell is completely immersed in the fluid, in the container. In a dry cell, the plates are separated by a series of gaskets and the fluid travels between the plates through a series of holes. The plates of a dry cell are not immersed in liquid- it is fed from a separate reservoir. There are advantages and disadvantages to each one, which is why we have developed and patented our unique HYBRID CELL. It takes the strengths of both wet and dry cell technology and combines them, while eliminating the weaknesses. Our 800 Series Cells are even more advanced than our Hybrid Cells.

17. Can your kit work with my Prius or other Hybrid cars?

Yes, but...Currently we don't support hybrid vehicles because they are a special situation. They need a very special installation approach which is not necessarily for beginners. The kit must be tied into the engine oil sensor or other component that allows the generator to turn on and off with the gas motor of a hybrid, which cycles on/off constantly. If you want to tackle that job using a series of relays or a transistor, you can get the hybrid to work well with HHO; and you must use a wideband efie. 
If you are still interested in proceeding, contact us- we can help guide you through it.

18. Do I have to make any changes to my vehicles engine or vehicle computer?

On newer vehicles, the engines computer reads the info from the O2 sensor, Throttle position sensor and the Mass air flow sensor and then makes the necessary adjustments to the fuel/air mixture automatically. We offer the efie and maf enhancers, or the diesel tuners. Those turn off when the kit is turned off, so the car reverts to original settings.
You do not have to modify the engine at all. The only thing you add is a small hole for a threaded fitting for the hose to attach to. The engine remains stock. You can remove the kit before selling the car and it will revert to OEM specs.

19. Will This Ruin My Warranty? What Will My Dealer Say?

This is a very controversial question and as far as I can tell- every one of our competitors tells you- "No Problem! The Moss Magnusson Act takes care of that!"

So I am going to be completely honest with you and give you the truth here.Most dealers do not like ANY modifications to cars under warranty including better exhaust headers, high flow intake manifolds, and even HHO generators. You need to check with yours, but chances are they are not going to like it (mostly because they are not familiar with the technology).

Now, yes, there was a Moss Magnusson Act passed ( I have a copy of the bill here), here in the US, that is designed to prevent dealers from Not honoring warranties for aftermarket products added on, as long as that product could not be blamed for any warranty work. For example- you take your car in to get a broken door hinge fixed, and they void your whole warranty because you added a high flow intake to help with mileage. This prevents them from making a blanket judgement like that- they have to prove that the add on caused the damage. However- you may not want to take the fight on with your dealer and risk your warranty. If you install them and maintain like we show, they will not harm your engine.

Most customers save gas and reduce emissions all year, and will just quickly remove the generator prior to warranty work and then reinstall after. We did that with our Nissan Maxima for years with no problem.

20. What if I run out of water - will it burn up my system?

No! The only thing that happens is the unit will stop working. The water acts like a wire or conductor for the electrical current to travel through so: no water = no current = no hydrogen.

It will not burn up, though it might get some oxidation on the plates inside. We have a product that can be poured in and flushed out- renews the plates if that happens. Most of the time- the simple solution is to just add more water.

The thing is: you will notice immediately when the kit drops performance- not as much pep or acceleration. Amps will change dramatically. All indicators before you run out completely. It does not use a lot of water-  and is easy to check once a month.

21. If I decide to install your kit on my car, will I get rust or corrosion?

Not any more than any normal engine produces through condensation (you see this coming out as water from the tailpipe when cars are warming up on a cold day). When the hydrogen-oxygen gas combusts, it reverts back into water, and super heated steam (in very small quantities) which helps clean the carbon and sludge off the inside of the engine. Normal engines produce moisture and condensation all the time- the reason most exhaust systems are now made of stainless steel.
