How much air can you add to a container with pure hho gas so that it will still burn?  Just wondering what the ideal air/hho ratio for an internal combustion engine would be. Stoichiometric air-fuel ratio for Hydrogen is 34:1 by weight which is over twice that of gasoline.  But you are also adding pure oxygyen so the ratio would be even be higher? Is it realtively easy to calculate the required volume of hho + air needed?.  Just thinkin out loud...sorry
