Gregory's Server@dr2chase I thought of something similar, but I wasn’t sure how usable it would be for the target audience.
I think corporations will probably be able to replace the plastic shell with some other material.
They absolutely have a profit motive to do so.
@AngryBull007 the larger problem with plastic is when it is disposable plastic. The bottle is durable, ideally, you would use it for many refills from a larger supply. HOWEVER, the default product delivery (for that product) is not via refills, but new bottles, so, that's a flaw.
