packet sized water plant?
A few cents for 2.5 gal of water.
It's an interim step towards getting clean water everywhere, but it is a huge step forward.
I've said it before, I don't care who makes it happen. I want to be part of the process, but if it's someone else, that's fine as well.
1 packet, 1 piece of cloth, and enough water for a family? It's almost the ideal box, pour water in, get clean water out. It's cheap, and easy to do.
Perhaps there's hope yet.
