just out of curiosity whats laughing gas ?

the same: N2O
the medical stuff is much cleaner than the automotive grade stuff (no oils, contaminants, etc)

note: NO2 is nitric oxide, N2O is laughing gas or nitrous oxide

the N2O assists combustion:
- it requires less energy to remove the O2 from nitrogen as it does water H2O or carbon dioxide CO2 - so the N2O is a willing participant in any oxydizing reaction such as burning petrol
- you help 'saturated' the atmosphere in the combustion chamber with compounds that release a great deal of energy when they oxidize (e.g. lots of extra fuel and very cold, dense NO2 gas)
- horsepower comes from the massive amounts of fuel and all the extra O2 released form the NO2 when heated and compressed in the combustion chamber, e.g. a much bigger bang when the spark plug lights up. If you get this mixture too lean (e.g. not enough fuel) expect the engine to die within seconds from massive detonation and pinging? i think you would want to run slightly rich if using N2O? Wink

important note: the explosion probably wasn't from the N2O burning - but from the massive release of pressure when the bottle opened up - N2O needs a fuel to oxidize with if you want lots of heat & energy - some of it will have reacted with water and other nearby stuff, but not in the way it performs in the combusion chamber. The heater (that led to this catastrophy) is to keep the gas bubbling off and to prevent the liquid N2O from freezing as the tank pressure fell from gas take-off.

... and all you ever wanted to know N2O (regarding your body):
It leads to loss of balance, loss of awareness of any stimuli, including loud noises, and speech, sharp mental deterioration and eventual lapse into unconsciousness.

The main effect is depression of the central nervous system, including the brain, stem and spinal cord, which eventually stops involuntary actions including breathing, partly because of the effect of the gas itself, but also because of oxygen deprivation.

A person rendered unconscious by nitrous oxide is likely to stop breathing within a few seconds. All it takes is a series of breaths without oxygen in between. If a person remains conscious and stops breathing the nitrous oxide, full recovery is likely within minutes. However, someone who continues to inhale the pure gas after losing consciousness will almost certainly die.

(search Google for "laughing gas NO" to find more)
