==How much | ==How much material for the container: Estimating the ''absolute bare minimum'' required== | ||
Using physics, there is a general formula to estimate the theoretical minimum material-to-gas ratio, for ''any material'' containing ''any gas'' at high pressure. | |||
a = 1.5 R T D / (S M) | a = 1.5 R T D / (S M) | ||

Stainless steel contains more than just iron & carbon. It also contains nickel & chromium, which are scarcer resources. {{pn|Need to do an analysis regarding mineral reserves.}} | Stainless steel contains more than just iron & carbon.
