Note that at 1:31 in the video they give the formula, and display a molecule of water as having 2 oxygen and 1 hydrogen atom (or HO2). Such elementary (no pun intended) mistakes don't earn you much credibility.

Aside the technical boner that therealblankman noted, this seems rather legit. The science behind it, however, is not appearant. Unless he's figured out how to break thefirst law of thermodynamics (though they mention plugging in the machine), I don't see how this machine is economically feasable. I will say, watching the one guy (Byerly) touch a lit torch that can supposedly cut through steel intrigues me.

The car is plainly impossible. You can't make fuel on the fly and get better (or even close to) the efficiency than we have now with out breaking the first and second laws of thermodynamics.

Video cut out for me toward the end, but I see a whole lot of problems. First of all, how is HHO different from H2O? The "2" after the "H" signifies two hydrogen atoms... water could be written as HHO, so I'm not sure what they're doing to water to make this gas.

Second, even if there is legitimate chemistry behind what they're saying, the claim that this will work as a fuel source is dubious. The machine that makes HHO has to be plugged in, and therefore is probably not self-sufficient. How much electricity does it take to make this gas? How much fossil fuel does it take to make that electricity? What's the efficiency loss during that process?

At best, it seems like they've maybe found a slightly better gas to use for welding. At worst, this is a pretty lame prank/scam.

on the contrary,it is very feasible.
The main problem with gasoline engines is the issue of inefficiency. Imagine a pie chart. Surprisingly, only around 15-30% of the energy stored in gasoline is transferred to the ground, the rest being lost as vibration, and mainly heat. Beyond this, there is still leftover fuel in the exhaust that isn't burned. By creating hydrogen and oxygen, not only are you creating two very volatile gasses, you are generating an extra source of oxygen for the combustion of the existing fuel.
