What is HHO?

5. How do i know what gauge wire to use in my HHO system?

HHO is a gas composed of two molecules Hydrogen & one molecule Oxygen and is created by the splitting of water through electrolysis.The electrolysis of water produces a burnable Green Gas. HHO is commonly reffered to as Brown's gas, Oxyhydrogen, Klein's gas,Green gas, Hydroxy,Di-Hydroxy and Water gas.

HHO gas packs three times more energy than gasoline and will ignite in concentrations of less than 4% of the air volume. It has been recognized around the world as a viable alternative to gasoline. As Hydrogen Generators develop and become more effecient, our need for fossil fuels will decrease and so will pollution and global warming.


Why do i need an HHO PWM?
Pulse Width Modulators are a crucial component of any HHO system. Just ask any commercial HHO system installer what the number one problem they encounter is and they'll likely tell you it's " heat ".

Secondly, conventional electrolysis will only get you so far. To really see what your HHO Cell can do, you need electronics.

HHO Pulse Width Modulators are very effective in reducing heat and controlling amperage. We strongly discourage wiring any HHO Generator directly to the battery without  an HHO PWM.

Use the chart below to determine the correct amperage wire to use with your HHO PWM.
Can i increase production by reversing the polarity of my HHO Cell?

Switching the polarity of the plates will hurt production. If you watch the liquid while the unit is running, you will notice that the water is moving. What you are seeing is the magnetic pull of the oxygen and hydrogen particles. The hydrogen molecules are attracted to the negative plate and the oxygen to the positive. While switching polarity may knock off the bubbles that are stuck, it will probably hurt overall production. Once the polarity switch is made, the magnetic field will change directions which means the water will have to slow, then reverse its direction.
When HHO gas combusts the hydrogen and oxygen gasses rejoin only to become water again.
But that doesn't mean you will have water pouring from your exhaust either.
There is always less water coming out of the exhaust then first went in, this is where the energy is lost and dissipated as heat.
The HHO generator, ( HHO cell ), will always need to be refilled with water thus it is not free energy and thus is not breaking the laws of thermodynamics.
The energy is coming from the water, that water will eventually run-out and then need to be refilled.
This need will always be there.
Some of the newer design HHO systems have large capacity resevoirs with check valves for this reason.
What Effect does vacuum have on the boiling temperature of my HHO electrolyte?
Use the chart below to see the effects of vacuum on water's boiling point.
Will Hydrogen Gas damage my engine?

A: NO!, The only way of damaging the engine would be from running it too lean or from hydrogen embrittlement. We would also state that even though many thousands of HHO cells have been installed around the world we have yet to hear of one case of engine damage from the hydrogen itself. Here is an excerpt from Wikipedia :
" Tests have shown that aluminum and beryllium copper alloys are some of the least susceptible to hydrogen embrittlement along with few other metals. " So those with aluminum intakes and aluminum cylinder heads need not worry. Here's one more: " High-strength and low-alloy steels, nickel and titanium alloys are most susceptible. Steel with a ultimate tensile strength of less than 1000 MPa or hardness of less than 30 HRC are not generally considered susceptible to hydrogen embrittlement. " Most engine blocks are made from " Grey Cast Iron " and wikipedia states the following, " Silicon is essential to making grey cast iron as opposed to white cast iron. When silicon is alloyed with ferrite and carbon in amounts of about 2 percent, the carbide of iron becomes unstable. Silicon causes the carbon to rapidly come out of solution as graphite, leaving a matrix of relatively pure, soft iron. " So it being a soft metal alloy makes it an unlikely candidate for embrittlement.
