Well, I'm gonna patent "drinking water", "breathing" and "having sex".. I'll rule the world!

Patent: Compound Gas and all processes involving it
Compound gas that consisting of 78.08% nitrogen, 20.95% oxygen, 0.93% argon and 0.038% carbon dioxide, rest being of no significance. The gas can also contain water vapour to a varying degree. Can be used to transfer heat or move pistons with pressure. Also can be used to fill vehicle rubber wheels. Other uses include, but are not excluded to, gas transfer to and from blood, floating in it with a vehicle that has smaller net density than Compound Gas, or using foils and high velocity to create high and low pressure zones around the foils, which cause a varying amount of Compound Gas to move into a direction x, causing a force vector to be applied to the foil into direction -x (opposite of x).
I mean, it's kinda complex combination, it must've taken me some effort to figure out this kind of exact ratios for this gas... damn it has some curious applications too.
