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
there's no reason I should be throwing away any bottle at all to get tap water with bubbles in, and I don't want to have to buy proprietary CO2 cylinders that contribute to apartheid in occupied palestine
@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.
@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!
