Great invention Nick and will undoubtedly save lives but the only problem with this is if lives are saved in great numbers that would otherwise die from natures natural selection then sooner than later there won't be enough water or food for that matter to feed these people or millions of others

There is going to have to be a lot more thought put into this than meets the eye in my opinion

This has been bugging me. I cannot, in all sincerity, accept that letting people die unnecessarily and agonisingly from dysentry, polio, cholera, etc. can be either rational or, indeed acceptable.

Two points spring to mind: First, natural selection has nothing to with this. Whether it's an Asian tsunami, a flood, an earthquake, or even day-to-day living, it is morally unacceptable to say "Let them die, it'll help keep population down!" Secondly, one reason why the number of children born per family in third world countries has been (and still is) so high, is the problem of high infant mortality. If third world countries had a better standard of living, the birth rate would go down naturally, as it has in the developed world.
So, there's nothing to think about, IMHO. This device should be made widely available throughout the world.
