It is a Hoax, obviously, even worse than the cold fussion one. 
Nothing new, except that H2 and O2 are gases at room temperature and pressure, not liquids, and they are not very soluble in water, specially H2.
Burning H2 (gas) and O2 (gas) is how the space shuttle works, it burns H2 and it uses O2 as the comburent.
As Xenocrates says, the hydrolisis proccess is energy consuming, and if you combine the two reactions (hydrolisis and combustion) you have water at the beginning and water at the end. Therorically the best you can do is to break even in energy terms. In practice, the energy you obtain burning H2 and O2 is less than the energy necessary in the electrolisis proccess.
That is not the way. If you ionize H2 into H+ you'll loose electrons and you'll release a lot of energy in the process, so you'll lose the energy needed to ignite the tip before it gets combined with O-.
Same happens with the ionization of O2, BTW, the best you can do is O2^2- as in oxigenated water, O^2- or O3 (ozone) which is very toxic and reactive in lower atmosphere. There is no O- ions.
Yeah, supposing the other things were correct, all you are really doing is storing energy (not electricity). That is the truth behind the hydrogen car technology. The problem, though is to store the hydrogen (H2, not H+) and make it available. And in this case if it is ionized hydrogen is not H2 and ionized H+ gas per se (alone) is not stable at room temperature. Not even hydrogen radicals are stable at room temperature.
The only way to have H+ in water is having a counterion stabilizing it. When you dissolve HCl gas in water you end up having H+ and Cl- dissolved in water. But those H+ are not going to react with O2 or with any other form of oxygen and feed a flame, Why? because combustion is an oxidation proccess, H+ ions are already oxidized and there is no way H+ can loose more electrons because it doesn't have any left. H+ is just a proton.
As a side note, pure water have some H+ dissolved in it, more or less at a concentration of 10^-7 molar. That is what pH of water = 7 means. They are in equilibrium with H20 molecules. H20 <---> H+ + OH-
Yeah, strong acids tend to react with metals. It is not strictly a rotting proccess. Rotting is produced by oxygen, who gets reduced (gains electrons) by oxidizing the metal (who looses electrons). The acid attack happens when H+ gets reduced to H2 and oxidizes the metal.
