Oxy hydrogen?

Question

Oxy hydrogen?

Answer 1

Doesn't appear to be useful as  fuel.  Particularly  since it can't be stored at high pressure.  I bet you are looking at one of the SCAM systems out there that claim magical increses in fuel efficiency with this source.  They are all a crock of lies.  I found several websites touting it's use but I simply don't believe them.  I won't put a link to them here as I don't want to perpetuate a false idea and steer people wrong.

Oxyhydrogen is a mixture of hydrogen and oxygen gases, normally assumed to be in a 2:1 atomic ratio, the same proportion as water. When ignited, this mixture combusts to water, making 142.35 kJ (34,116 gram calories) of heat for each gram of hydrogen burned: that is 286.97 kJ/mol of enthalpy. The flame is hottest in the burning of that stoichiometric mixture. It is less hot when there is an excess of oxygen or hydrogen, or when an inert gas such as nitrogen is mixed in, because there the same amount of heat is added to a larger amount of matter.

Oxyhydrogen of stoichiometric proportion can be made by water electrolysis and most commonly is.

At normal temperature and pressure, oxyhydrogen can burn when it is between about 4% and 95% hydrogen by volume[1]. Although, if the gas velocity out of a torch tip is too great there will be ignition difficulty as the flame will tend to blow itself out.

Oxyhydrogen explosions can be a hazard where water electrolysis happens unintentionally, for example in large lead-acid batteries.

Oxyhydrogen cannot safely be stored at useful pressures because of its explosive nature. Relatively low pressures can be achieved, allowing the application to pressurized torches.

Answer 2

Oxy-Hydrogen gas is easy to make. Of course this gas is too dangerous to be of any practical use, but who wants to be practical ALL of the time? Please note that this gas is OXY-Hydrogen, and not pure hydrogen. Pure hydrogen can be stored safely, but Oxy-Hydrogen is HIGHLY EXPLOSIVE and CANNOT BE STORED SAFELY under any circumstances!!
