HHO generators were first proven in the welding industry but have
now become a hot commodity in the automotive industry as well. HHO
generators for cars are built or bought by many who want to save
on gas mileage and reduce emissions.
Electrolysis of water is the basis for HHO generators that usually
also require some electrolyte in order to make the distilled water
more conductive to electricity. Sodium hydroxide (NaHO) or Potassium
hydroxide (KOH) are two electrolytes commonly used in some hydrogen
A word of caution is due here. Electrolysis of water (H2O) creates
hydrogen and oxygen (HHO gas) which is very flammable and combustible
so proceed carefully if you decide to build your own HHO unit. Also
NaHO and KOH also need to be handled with care using gloves and
HHO generators for cars, trucks and other vehicle create the oxyhydrogen
(sometimes called hydroxyl) gas from water, inject it into the vehicle's
intake system where it helps the gasoline or diesel fuel burn more
cleanly with less emissions. Fuel mileage is also increased, many
Most HHO generators are arranged in a parallel cell or series cell
configuration. Some DIY builders have reported disappointing results
when using a small single cell with the incorrect mix of electrolyte.
Arranging several HHO generators in a series is sometimes needed
in order to produce enough oxyhydrogen gas, along with the correct
mixture of electrolyte.
HHO generators are endorsed by the National Hydrogen Association
and just the companies listed with the NHA have logged over 50 million
miles of road use. The NHA also calls them hydrogen fuel injection
Now, I would like to just mention the HHO torch used in welding
since I have another page devoted to this subject. Names like William
A. Rhodes, Yull Brown and Denny Klein have all used an HHO torch
with demonstrated success and there are some of these devices currently
To sum up, whether you're a welder or a driver, HHO generators
may just be the clean solution for which you've been looking. Since
you can build and HHO generator yourself why not give it a shot?
Most people find it is worth their time and very small investment.
