The Hydrogen on Demand System works by adding a small amount of a mixed hydrogen/oxygen gas,  into the vehicle's fuel system. This enriched mixture of hydrogen, oxygen (oxyhydrogen) and gasoline is bonded together molecularly and magnetically. The combined fuel results in better fuel economy and an increase in miles per gallon. Usually this increase is in the range of 25%-50%!

Improved mileage is not the only benefit resulting from the use of the Langs' Gas Power Booster. Other benefits may include:

A noticeable increase in engine power. Less pressure is needed on the accelerator pedal, to get the vehicle up to speed.
The new fuel mixture burns cleaner, burns more completely and burns more efficiently. It cleans up carbon deposits in the engine and prevents future carbon build up.
Exhaust emissions harmful to the environment are greatly reduced.
The combustion chamber temperature drops slightly, contributing to better fuel combustion and a quicker flame spread ratio.

Adding Brown's Gas to the fuel/air mixture has the immediate effect of increasing the octane rating of any fuel.“Octane Rating” means how much that fuel can be compressed before it ignites. Low grade gasoline (what's called “Regular” or 87 octane in California) ignites faster than higher octane fuels. It takes less compression to ignite. This fact causes the gasoline to ignite before TDC (Top Dead Center, the point where the piston is at the highest point of its motion), making it less efficient because the explosion of gas fumes pushes the piston down and out of sequence (it's too early so it goes a bit in reverse) and therefore the “pinging” noise and less power from Regular gasoline. Brown's gas or water vapor causes regular low-grade fuel to ignite more slowly, making it perform like a high octane gasoline! A higher octane rating means stronger horse power due to combustion occuring much closer to TDC, where it has a chance to turn into mechanical torque (rotary push) the right way and without pinging Each piston transfers more energy during its combustion cycle, so combustion becomes more efficient – as well as SMOOTH. More efficient combustion translates to less fuel being consumed.


You see, this technology does not mean we're running on water, but introducing HHO simply and effectively creates the effect of using the same bad gasoline in a more economical way. It supplements and actually CORRECT the behavior of gasoline. Free energy does exist, but it has to be triggered by something. In this case, the interaction between water and gasoline is how it happens.

This is the main component. It is called the Electrolyzer.

HHO (hydrogen hydrogen and oxygen) burns so efficiently it can increase vehicle mileage anywhere from 30% right up to a staggering 250% for large trucks. An HHO conversion kit is added to the existing gas or diesel engine thereby reducing the need for so much of your normal fuel.
Although is is environmentally very friendly, the main attraction for most people is the money it saves them. Most people have covered the costs of the HHO conversion kit within a month or two by simply saving on gasoline at the pumps. It won’t affect your vehicle’s warranty and can be very easily removed at any time without having any impact on the existing engine.
In fact, by incorporating HHO fuel into your engine, it will reduce heat as well as carbon build-up. A Brown’s gas (HHO) hybrid increases the power or torque of the engine, thus exerting less strain on the engine, particularly when pulling uphill. Most engines, if converted from new, will last approximately 70% longer than a car, truck or SUV run solely on gas or diesel.

Not all cars, loads and driving conditions will gain the same, obviously. For ethical reasons we do not build up expectations for more than 30%-50% improvement in fuel economy, however we are getting daily success stories from experimenters who are seeing gains of 80%-100% in various vehicles. For some, significant economy gains inflict a revelation that something can be done about it, while for others it's a life changing factor.
