Stuart,
I don't know what the additional 100 mg/L oxygen will do, I bet nothing because in the air there is about 20% of this gas.
About 50'000 mg/sec of pure oxygen in my LS1 engine at WOT
However: this of the beverage bottles is turning in my head since a couple of days. Is it realistic to fill one of those bottles with water or watever, pressurize the bottle and spray the liquid without a pump?
I think those bottles can handle some more pressure than 3 bar, so why not "spray from the bottle"?
A little 12V air pump
A pressure switch + safety valve for the bottle
A pressure switch to spray
Why not?
