@Gogarty.news.bway.net:

You make a very good point. Are there not emergency stills that work on
sunlight?




Yes. Only trouble is they are evaporators, not stills. Biology grows
right up to around 180F so these solar evaps are easily contaminated, a
source of nasty bacteria because they are just right inside in temperature.

If you don't see it boil, it just isn't safe.
