I think the gas is created by decomposition rather than oxidation (flame) -- he notes the gas is 260 degrees Celcius which is actually quite cool -- certainly cooler than a rocket flame. Thus, it may be a pressure leak but not an actual flameout.

 

meilers your right about the decomposition reaction. But I think in the video something screwed up in the turbine causing the equilibrium in the H2O2 decomposition to get messed up and extra H2 to be formed changing it into a combustion reaction. EvoHunter as far as H2O2 as a fuel, it only decomposes or combusts at extremely high concentrations. The hydrogen peroxide you have in your cabinet is at about 3%, the concentrations needed would be 70-90% (military grade H2O2 used as rocket fuel). At these concentrations it would be horribly hazardous and corrosive making it a pain to transport and store safely plus when exposed to light and I think even air it decomposes easily into O2 and water which makes it even harder to store.
:banana:

 

He's right, hydrogen peroxide is EXTREMELY dangerous in high concentrations, it reacts with almost anything and is corrosive and explosive.

You can run a piston engine on vegetable oil, kerosene, N20, alchohol, methanol, propane, liquid propane and even hydrogen gas -- none of them has proved as cheap and as easy to store (or as safe) as gasoline.

OH, and BTW -- if he had combusted H2, you would not be able to see it. Hydrogen burns with an invisible flame and does not make smoke.

 

Hydrogen peroxide is essentially water. Does this device use the H2 or the O2 when it decomposes? I vote for water being essentially, unburnable.
