Crafted by a potter named M Sivasamy, this clay pot was designed to help keep produce cool for days.

He made a cylindrical pot made out of clay with a tap on one side and an outlet to pour water on the other side. A smaller pot fits inside the bigger one where you can place your vegetables which is then covered with a lid. The technology is simple — the water in the pot remains cool keeping the vegetables fresh and cool. - BetterIndia

For places with no or limited electricity, this could help immensely. Especially considering terracotta(earthenware) clay is almost used worldwide.

    I was replying to dbx12 - they are implying that this method has only just been discovered. It’s been known for hundreds of years, these articles are gaining traction in western media as if its a new discovery and we should applaud how clever the locals are.

    Fair enough though, this article wasn’t, but my point stands.
