We are often asked ... Does an ‘Hydrogen on Demand - HoD/HHO Cell - work ?

The straight answer to that is ... YES ... hundreds of thousands ( in all shapes and sizes) are working today ... all over the world !

Put another way ... Hydrogen on Demand (or HHO) Cells work on any vehicle which uses a petrol or a diesel engine. Large or small ... 2, 3, 4 or 18 wheels ... all ‘hydro-carbon fueled’ vehicles are suitable; fuel and vehicle performance and exhaust emissions can always be improved !

An HHO Cell produces a gaseous fuel additive which both improves the range and performance of your hydro-carbon fuel and delivers a ‘near pollution-free’ exhaust stream.

Paradoxically, it is widely recognised that all ‘conventional’ internal combustion engines are very inefficient devices; usually delivering barely 40% of the energy in your fuel; often less - and doing so through a ‘less than complete process cycle’.

Conversely, up to 70% of the fuel’s energy is wasted, with unburned fuel needing to be burned in a ‘catalytic converter’ to help reduce emissions.

In ‘diesel-engined’ vehicles … precisely such a ‘special device’ is built into their exhaust system; It is called a ‘Diesel Particulate Filter (DPF).  When a driver is warned that the DPF is ‘full of particulate matter… soot from the engine’; he must have the DPF removed as soon as possible (for he is then using the vehicle illegally) from the vehicle and emptied. The ‘soot etc’ is destroyed in a special furnace and the DPF is replaced..

Eventually, catalytic converters can, and do, fail altogether: They are expensive to repair or replace; and before a complete failure - a ‘blocked’ catalytic converter costs both mileage and money for a replacement.

The ‘Hydrogen on Demand’ (HHO/HoD) Cell is used to create gases from plain water (with a commonplace additive, KOH -  Potassium Hydroxide - dissolved in it; and using, essentially, ‘spare’ energy in your vehicle’s battery. A correctly functioning ‘battery / alternator combination’ can always do this.

If you pass electricity through water; most school children will know that both Hydrogen and Oxygen are produced. Conventional teaching explains that distilled water is comprised of ‘Hydrogen’ and Oxygen’ (H2O) and describes how both gases can be extracted from water by the application of, low voltage, electricity.

Simple !  Well actually, there’s a little more to it than that.

Every litre of water contains exactly 111.19% Hydrogen and 888.81% Oxygen, by weight. That’s about 1850 litres of Hydrogen and Oxygen - in every litre of water - combined, at atmospheric pressure.

Furthermore, to make matters a little clearer. Modern science has discovered that by electrolysing water - and providing for the main, released, gases ... Hydrogen and Oxygen ... immediately to re-combine - the complete process actually produces not just hydrogen and oxygen but also some ‘trace gases’ combined in a more complex gas mixture.

This mixture has been named ‘Brown’s Gas’ after its discoverer; Prof. Yull Brown.

For further information look here ... Browns Gas

Presently, we cannot simply use ONLY electrolysed water to fuel a motor vehicle. But, history records that a researcher, an American engineer named Stanley Meyer, did achieve that result - in the early 1990’s. Tragically, mysteriously, he died from apparent ‘food poisoning’ after a meal with several persons who ‘made him an offer ...’ to acquire his secrets!

So ... let’s temporarily agree that Brown’s Gas - being produced in an HHO/HoD Cell, cannot, yet entirely substitute for the need for conventional fuel in your vehicle. Neverthless, in today’s complex world; it is abundantly clear that the Hydrogen on Demand (HHO/HoD) process does have a vital role to play in extending the life of conventional hydrocarbon fuels by:

  1. Increasing the ‘burn rate’ of your existing hydrocarbon fuel ....
  2. Raising the efficiency of combustion in engines, and especially ,,,

3. Virtually eliminating pollutants in the exhaust stream of any motor vehicle ...

   Simply put ...

Hydrogen has a faster ‘flame speed’ than any fossil fuel and

causing it to burn makes the hydro-carbon fuel to burn more completely.

Only a tiny amount of Hydrogen is needed; Yet, when mixed with a vehicle’s existing fuel, and combined with Oxygen and other traces of gas in Brown’s Gas - all derived, in real-time, from an HHO Cell - it will provide for a more powerful, more complete, and more efficient burn of the existing fuel.

Even Formula One racing cars could benefit from it ! ... I wish ...


Not only does this ‘enhancement’ of the fuel-mix cause an engine to run cooler; researchers have proven, beyond any doubts, that it virtually eliminates all carbon deposits - and other un-burned particles which would otherwise persist in the engine - thereby extending the life-expectancy of your engine.

In practical terms ... if a truck / car is producing a smokey exhaust ...

with an HoD Cell installed the smoke disappears !!

Whilst reflecting on the amazing work of Stanley Meyer, above ... and regretting those in the then motor and fuel industries of that time; who feared his science and wanted to eliminate him and ‘shelve’ his invention: And, being mindful of more modern ‘nay-sayers’ whose misplaced doubts and scepticism have largely dwindled into obscurity; It is important to note that many thousands of ‘hobbyists, experimenters and users’ in  the world - daily, drive their HHO Cell assisted vehicles - with smiles on their faces.

Note also, the growing lists of respected Motor Insurance Companies in the UK and elsewhere, worldwide, who have come to recognise an ‘HHO/HoD Cell’ for what it is ... simply an ‘attachment’ to improve fuel efficiency, which delivers cleaner exhaust emissions and a longer engine life ... whilst consuming no more electricity than a ‘fog light’ on a vehicle.

A typical HHO/HoD Cell, can easily be installed under the hood (bonnet) of your vehicle.

Normally, it will be fitted between the front grille and the radiator ... and, on larger vehicles, multiple cells - ‘in series’ - are required.  Supplied fittings allow for electrical supply and ‘earth’ connections; whilst the necessary, piped, connections provide for water ‘in and out’, via the water reservoir, and for output gases to be fed into the fuel intake.

Typical HHO/HoD cells can take an hour or so to fit; and any hobbyist, or motor technician, can do the job.

If there are additional ‘electronic assist devices’ to be fitted - as there sometimes are, today - an HHO/HoD cell will take a little more skill and time to install.

A fuse protected electrical supply, and a relay, must always be installed; ensuring that the HHO/HoD Cell only runs when the vehicle’s ignition is powered on.

Some quality HHO/HoD Cells are available here ...  De Verde Limited.

When the vehicle is started, the HHO Cell immediately supplies ‘Browns’ Gas’ to the engine via the hoses and vacuum connectors - connected into the vehicle’s normal fuel inlet system.

Driving the vehicle is EXACTLY the same as without the HHO/HoD Cell attached.

Optimum performance/economy/clean-exhaust results will result from a driver using ONLY the lightest touch on the accelerator - consistent with road conditions, the law, and the safety of the driver and passengers.

On modern vehicles - equipped with Instant and Average Fuel Consumption displays - fuel consumption can be optimised by the driver using this ‘light touch’ accelerator approach at all times.

In fact, it has become a personal habit of this writer, and many other experienced users, to drive on level (and downhill) main-road sections - using only the lightest touch on the throttle - with the speedometer typically showing over 70 MPH (the UK National Speed Limit) ... and with an Instant Fuel Consumption gauge showing in the region of 140 -190 MPG !

Finally, a few bullet points to remember :-

News Bulletin ... In the USA ... Drivers using HHO Cells can obtain a Personal Tax discount for driving a vehicle with an HHO Cell ... up to $2000 in (personal) tax rebates for anyone willing to convert their car to run on HHO gas together with conventional fuel. That’s a sure way to show that it does work ...

We are campaigning for the UK Parliament to make the same move ... soon please !

Just to make my point ... if you key this query into Google  ...

“US rebates to use HHO Cells, proof”

 ... here’s one of the answers ...

... another fact is that the US government will pay up to $2000 in (personal) tax rebates

to anyone who is willing to convert their car to run on HHO gas as well as fuel.

another sure fire way to show that it does work ...
