if you want to encourage responsible use of non-renewable materials, please sell growlers and get someone to R&D a municipal water growler fill station that works off industrial CO2 cylinders @PCC@twitter.com
@vogon I thought 425g CO2 cylinders were industry standard.
@jautero huh! I was always under the impression that the socket end was proprietary and patented, but that might be a mistaken impression. I'll do more research, thanks!
@vogon It seems to be at least ISO standard. I think the reason is obvious. Good luck getting your proprietary pressurized gas container pass all safety regulation.
