  • palvarezcruz reply It seems expensive. The people from places where this would actually bring an advantage aren't wealthy enough people to afford it. And if they could, they'd be able to afford water so it becomes pointless. Donating these for a whole community would probably be too expensive. Maybe a community toilet that several families use could work. As long as it can withstand that kind of use. It's pretty interesting and it's always good to see people developing things for good.
