HHO gas is a fuel additive that has been around for the best part of a century. During World War 2, Pilots flying low over water reported having much better fuel efficiency. Further Research showed that the HHO Gas Vapor created from the heat of the plane mixed with the fuel in the engines and resulted in a more controlled gas burn.
What does this mean?
Well put simply, these pilots were getting much better gas mileage from the addition of this HHO gas.
Unfortunately even though HHO gas (a.k.a. Brown's Gas and OxyHydrogen) has been around for years it was never released to the public. Fortunately for us a few creative inventors raided a patent office and were able to get HHO Generator plans to share with the world.
Chemically, HHO Gas is simply free floating Hydrogen and Oxygen atoms. The baking soda which you add to the generator acts as a catalyst inside the HHO generator and helps to break apart the Water Molecule. This Gas is then piped into your engine through the air intake (diesel engine) and the vacuum lines (on a petrol engine), it then mixes with the fuel vapours in the engine increasing the octane rating of the fuel.
The way an engine normally works is you have little metal plugs called pistons moving rapidly up and down at (hopefully) a constant rate, this generates the power for the car. When a piston lowers it creates a small vacuum which sucks in fuel and oxygen (Intake). When it rises it compresses the fuel (Compression) and the spark plug ignites it (Power). An engine will ideally only fire the piston when it has completely reached the top of its tube, however, most engines fire early and don't burn the fuel completely. This creates inefficiency, reduces your Gas mileage and creates pollution. (Exhaust) If your vehicle was 100% efficient you would have zero emissions and we wouldn't be contributing as much to global warming like we do.
When the HHO Gas mixes with your gasoline it increases the Octane rating and the amount of compression required before the Gas ignites. The piston must then compress the fuel completely before it ignites, and the added Hydrogen and Oxygen allows the fuel to burn more completely reducing the amount of waste (emissions). So because there is less fuel being wasted as exhaust fumes you use less fuel. This also adds a bit more power to the engine, which increases its efficiency and improves your Miles per Gallon giving you better gas mileage.
How do we make the HHO?
So it's all very well knowing what HHO does, but how do we make it.
What you have is a jar or specially made casing which must able to be sealed completely. I used a large glass spaghetti jar and then made a stainless steel sleeve to protect it a bit more from the heat of the engine and any knocks it may get. The lid has a thick plastic thread on it so it seals completely. Glass is good to use as it has as in credibly high melting point and is a good insulator.
You can make your own casing, a good plastic to use is Lexan (a type of polycarbonate) as it has good Impact and temperature resistance so it wont start to lose its shape like some acrylics will in the heat - it is quite expensive though so unless you really want to make your own casing for some crazy design you might be trying, then get a jar of some sort.
The jar you end up using should have a thick lid on it. The first one I made had a very flimsy lid and in the end it just cracked and wasn't very good. The one I am currently using has a stainless steel lid which is incredibly strong and is just much better in general. The only thing to note when using a metal lid is that you will have to use gromits on the bolts that go through the lid as otherwise they will short each other out through the lid and your generator wont work.
You fill this container with water and a catalyst (baking soda works well to make the water more reactive), mix it together and you have the electrolyte. This is the main "ingredient" in your fuel cell. You can use tap water or rain water but distilled water (de-ionised) is good to use as it is just pure water with no chlorine like in tap water or other pollution you might get in rain water. One litre of water expands to 1800 litres of gas so you get a lot of gas from the water you actually put in. You should change the water every few months and clean the fuel cell as it will get residue build up and it should go brown as well as you are making browns gas (HHO - named after the guy who discovered it).
Top the water up every few hundred miles or you could incorporate a water pump into your design but that is all explained in the guide you should get.
Next off then is you have stainless steel in your generator which acts as the conductor. You either have wire, plates or tubes (if you're feeling adventurous) - all three use different principles and designs to make them work. 316L is the top grade stainless steel you should use as lower quality stainless steels will have a much shorter life. The main idea is that you run a 12volt DC charge (the same as the battery in your vehicle) through the conductors, one is positive and one is negative (anode, cathode). This opposing charges force the water molecules to split and bubble off as oxygen and hydrogen (HHO).
The gas then goes to your engine as described earlier on and you save fuel! Fantastic!
And before anyone asks - IS IT DANGEROUS?
Let me tell you now that it is NOT DANGEROUS as long as you follow the guide and do everything as you're supposed to. You WONT BLOW UP as the HHO that you produce in the fuel cell is extracted and then used on demand, i.e. it is used up straight away in the engine, so there is no chance of it blowing up. Also nothing is pressurized, there are no pressurized containers filled with hydrogen fuel so you don't have to worry about anything going off like a bomb. If we were to store the HHO and pressurize the container then there would be cause for concern as a spark of any sort would set it off - the way WE do it, there is NO CHANCE OF AN EXPLOSION. I hope that puts a few minds at rest for those who think hydrogen = danger - it does not.
So hopefully you now know a little bit more about what HHO is and how it works.
This system can be used on anything with an engine - so the skies the limit!
You could use it on an energy generator in your home to reduce your fossil fuel usage to heat your house. Just an idea.
Thanks for reading.
