However, people obtained the same result much more sustainably before the advent of the Industrial Revolution. In hot, dry climates, we used porous earthenware jugs that were not only re-usable, but also kept water cool by taking advantage of natural energy sources.
The best known example is the Spanish 'botijo', an unglazed ceramic container that cools beverages by evaporation. Similar drinking containers can be found in other Mediterranean countries, as well as in Mexico (where it is known as a 'búcaro') and on the Indian subcontinent (where it is called a 'ghara', 'matka' or 'suhari').
The ceramic water cooler probably originated in the Indus Valley Civilization, which would make it 5000 years old.
