How Does It Work ?.

That's a good question. Probably you should also need to know the term 'hydrolysis'. From Wikipedia
Hydrolysis is a chemical reaction during which one or more water molecules are split into hydrogen and hydroxide ions which may go on to participate in further reactions... bla bla.
And similarly this product 'ayaQ' makes use of the process, simple as that. So next step is, we collect the gaseous at the top of the tower and connect it directly to the air-filter, which later will be sucked into intake port and mixed with gasoline for internal combustion.
I think that is more than enough theory for that process.
What do we use ?. We use distilled-water.
