Well, not really, but you are more than welcome to believe it is.
Making "hydrogen" is actually really difficult, the bond between hydrogen and oxygen is very strong (which makes water very stabil).
Takes a lot of ENERGY to break that bond.
That energy must come from somewhere.
So, you must PUT energy INTO the process in order to get hydrogen.. That is nothing more than converting one energy source to another (IE LOSS)..
Sure, running IC on hydrogen may turn up the efficiency of a IC engine, but because of the huge input of energy that was used to get the hydrogen it ends up as a total loss, more energy in the end used to make that IC engine pure than if you used good old fashion gas from a well..
Man has tried for many years to make things run on nothing, but it cannot be done.
Those devices are called perpetual machines or OVER UNITY machines..
HHO is bunk, it take huge amounts of energy to net a small amount of hydrogen, a 12V battery cannot provide enough energy to make enough HHO to make a engine cough..
As far as practicality of running IC vehicles from hydrogen, price out the cost of a hydrogen cylinder.. Then consider how many cylinders it would take to drive several hundred miles.. Then try to figure out just how you are going to get them filled when empty..
Then consider just how dangerous that would be in a accident..
Yeah, lets all strap a few hydrogen tanks to our vehicles :E
Not practical on so many levels but yet folks gravitate to junk science.
