The Mitsubishi Pajero Owners Club®

EssexBoy

While having my tints fitted last week, the guy who owned the place showed me his prototype HHO generator for his truck. This was basically a jam jar containing water, baking soda and coil of wire attached to the battery. Once the current was running, gas was produced which is fed into the air intake on his truck. His claim was that this vastly enriches the air using the pure oxygen and hydrogen produced. Result - better combustion and hence better fuel economy. He claimed he had heard of people achieving 50% better fuel economy as a result.

A bit of googling shows that there is a bit of a cottage industry out there doing this (mainly with jam jars), and also some commercial ventures selling books and kits.

Anyone have any experience of this? Is it bunkum or does it work?

RED and NECKS Springs to mind Wink

Sorry but....................... if it was that simple

Our Government would Tax water by 1.000% Evil or Very Mad

I've done some research and analysis on this now. It appears that the principle is true! Electrolysing water creates a mixture of oxygen gas and hydrogen gas. Using this to enrich the air supply to the engine would have the effect of making for a better explosion in the cylinder (and hence the need for less fuel to get the same power output).

A back of an envelope calculation tells me that my 2.5L Paj sucks in about 3750 litres of air per minute at 3000 revs. This 3750 litres of air contains 787 litres of oxygen - the rest being mainly nitrogen and a bit of CO2.

So to give me 10% more oxygen (a reasonable uplift in order to get a boost), I'll need to deliver more than 78.7 litres of the H2 and O2 mixture per minute. Sadly, this would require me to lug around a huge tank full of salty water with massive electrodes in it and an almighty power source. The weight of all this and the power drain would more than negate any benefits.

So the principle is good - but let down very very badly by the practicalities.

There are tons of websites out there advocating this technology - but I couldn't find one which debunked it in the simple terms above.

It's basically a load of bull! And anybody who really believes that you can run a car on water, with current technology, really does need to take a reality check ... 'snake oil' is a phrase that comes to mind ...

It is absolutely proven that you can produce Hyrdrogen gas from water, after all, water is 2 parts hydrogen, 1 part oxygen, commonly known as water, but also referred to as H₂O, oxygen di-hydride, hydrogen hydroxide, HOH, etc ...

The problem is, the energy required to seperate water into its gaseous components (Hydrogen and Oxygen) is significantly MORE than the energy produced by re-combining them (with combustion) ...

It's worse than a joke - which is why this topic is locked.

Just wondered if any one has tried or would try running paj on water we are trying it. Have built the hydrogen chamber connected to car battery and had it working on a gas cooker hob which worked, however the chamber blow up (water every where) couldn't see the flame and didn't have a one way valve on it so flame was sucked back up pipe and exploded how ever all is not lostd as once the container is replaced testing can begin again and all looks promising i will keep you posed all ideas and input is welcome

Personaly, if the car/engine manufacturers have spent billions, and decades trying to refine this sytem, and haven't succeded 100% yet, they do have them, just unit cost prohibits production, then a guy in the kitchen has no chance, but every chance of a house fire.

Good luck, get the first aid kit ready Laughing

working outside in the open for saftey(lol) this has supposedly been done before however will not be allowed as standard as no tax will be added. lots of info on the net about it

This topic keeps coming up ...

If it could work, it would solve many of the planet's pollution issues in one go ... (Obviously, it won't help the issue of billions of plastic shopping bags littering the planet Rolling Eyes

) ... still ...

It can't be a viable option with current technology though Sad

...

The energy required to extract the Hydrogen gas from the water is greater, (because of the energy dissipated in the process), than that created by subsequently burning it.

Now ... if you could harness solar power, to produce the electricity required to extract the hydrogen from the water, I guess you could be on to something dontknow

But - at what environmental cost to produce the solar panels (if you go that route) ... maybe you could concentrate a beam of sunlight to super-heat the water ... a bit 'James Bond' perhaps Rolling Eyes
