There is a company[1] in Indonesia that actually makes very nice versions of this tech.

I may have had an early version of this at home in Indonesia as a kid. Given how close we were to both sea level and the equator, the fact that the water was cool, even when site power failed for days, was bliss!
Ceramic filters are very common in Brazil, used in clay recipients which also keep the water cool even in summer without spending energy.
