Will the cost of these toilets ever make sense for that?<p>When I see things like &quot;Turn a 2L bottle into a light&quot; for a really poor area - I think awesome, something they already have laying around can make their lives way better.<p>When I see things like &quot;Nano-polmer super toilet for those without running water&quot; I just kind of shrug. Seems to cost more than adding running water, while still not providing a clean place to drink.<p>What am I missing?
