Water as Fuel

There are two or three main objectives for creating a Hydrogen Generator Unit - increasing the Miles Per Gallon (MPG) performance and reducing the harmful emissions are the top two priorities, while running the vehicle on water alone is a future objective.


The first two objectives are readily achievable, but running a vehicle on water alone is not going to happen for almost everyone. The internal combustion engine has efficiency less than 50%. This means that at least half of the energy available from the fuel which you use is wasted and does not produce useful mechanical output power. In many cases, that percentage can be as high as 90% wasted; but let's be generous and assume that your particular engine is especially good and manages 50% efficiency.


The main way of running an engine with water as the only fuel, involves splitting water into hydrogen and oxygen and then burning those gases to power the engine. To be self-sustaining, the splitting of the water has to be done by the electrics of the vehicle and that means that the efficiency of the water splitting has to be more than 200% efficient. That just doesn't happen with simple systems, so please forget the notion of building some device in your garage with a couple of hours work and waving goodbye to filling stations forever - it is not going to happen.


Just to set the record straight, it is possible to do just that, but the difficulty level is about the same as building a rocket capable of going into orbit, which is something well beyond the capabilities of most people. Please understand that it calls for exceptional skills, very considerable expenditure and a great deal of patience, so for the time being, please forget about it.


What can be done quite readily and at a low cost is to construct a device which will raise the efficiency of your engine. This is done by feeding a hydrogen/oxygen gas mix (called hydroxy gas, Brown's gas, HHO gas) into your engine along with the air which is drawn in to make the engine run. A device of this type is called a "Generator or a Booster" as it boosts the fuel burn, extracting a greater percentage of the fuel's available energy. An important side effect of this improvement in the burn quality of the fuel is the fact that unburned fuel no longer gets pushed out of the exhaust as harmful emissions.


Another effect is that the engine has greater pulling power and runs smoother. Inside your engine, carbon deposits will have built up from previous un-boosted running. These deposits get burnt away when you use a booster and that extends the engine life.


Some people worry about the fact that burning hydroxy gas produces water and they imagine this water causing rusting inside the engine. What they do not realize is that the ordinary fuel used in the engine is a "hydrocarbon" which is a compound of hydrogen and carbon and that fuel actually splits up to form hydrogen which the engine burns. Actually, it is the carbon part of the hydrocarbon fuel which is the problem, producing Carbon Dioxide (greenhouse gas), Carbon Monoxide, and physical carbon deposits inside the engine. A normal fuel burn produces water anyway, but you don't get rusting inside the engine as the temperature there is so high that any water is in the form of steam or vapor which dry out completely when the engine is switched off. Adding a small amount of hydroxy gas has no adverse effects at all.



Just to make sure that you understand what is involved, a booster is a simple container which holds a set of plates submerged in water which probably has an additive to make the water conduct electrical current better. A pipe from the top of the container feeds the gas into the air filter of the vehicle, via one or two simple safety devices. Adding this gas causes a major improvement in the quality of the fuel burn inside the engine and cuts harmful emission to near zero.


As a consequence of this, it is possible to reduce the amount of fossil fuel being sent to the engine. This is not something which should be done if hydroxy gas is not being added as the engine is liable to overheat and some damage could occur. It is a completely different matter if hydroxy gas is being added. However, all recent engine designs have an Electronic Control Unit (ECU) which controls the amount of fuel being sent to the engine. The ECU  accepts input signals from an "Oxygen Sensor" placed in the exhaust stream, and often a second sensor after the catalytic converter to make sure that the catalytic converter has not failed.


Unfortunately, the much improved exhaust caused by the better fuel burn caused by the hydroxy gas, causes the ECU to think that the engine fuel-air mix must be too low, and so it pumps in more fuel in an effort to compensate. Ideally, this can be dealt with by adding a circuit board which adjusts the signal coming from the oxygen sensor so that it is correct for the improved fuel burn.


So, to recap, the only practical device which you can build yourself and use to improve automotive performance is a "Hydrogen Generator/Booster". Using a booster improves the efficiency of the fuel burn inside your engine and that results in more power, better torque, smother running and vastly improved exhaust emissions. If the ECU is not adjusted or its input signal not controlled, the MPG figures may actually get slightly lower due to unwanted excess fuel being pumped into the engine. If a control circuit is used to correct this ECU error, then MPG gains will be produced.


There is the possibility of your MPG actually decreasing. The most common cause is a vacuum leak caused by the installation of your device. But too much hydroxy gas mixed with your gasoline can cause your motor timing to fire too soon - before Top Dead Center. Hydroxy is very explosive. Its flash rate is many times faster than gasoline. The more of it you put into your engine, the more volatile your air fuel ratio will become. If your gasoline burns too fast, it causes a negative force on the piston before it gets to TDC. That is like trying to drive with your foot on the brakes; it slows the vehicle and wears the parts down. To over come negative MPG gains, it may be necessary to change the timing of the motor. Retard the timing so that it fires closer to TDC or in some cases after TDC.


There is another alternative for us to consider; Plasma Arc.
