Let's be positive. Though it's a long shot and probably unlikely usable in the developed nation context, there are 7 billion people on planet earth many of whom might be stricken in the coming months (and years), if someone can put together a solid, reliable, simple piece of gear that works, it's not unfeasible that 'someone' could pay for rapid manufacture (this is definitely possible) and distribution in far-flung places wherein 'basic' might just be a lot of help. Or maybe not, but it's maybe worth trying. It 'starts somewhere', so I hope it works.
