Cool fridges

Nick Kempson, a 2007 Volunteer & Founder Member of the Mercy Home Foundation just FaceBooked me with this fabulous invention.

Mohammed Bah Abba actually invented the fridges in 1995 but they're so simple its definitely worth spreading the news as far as possible.

"You take a smaller pot and put it inside a larger pot. Fill the space
in between them with wet sand, and cover the top with a wet cloth. When
the water evaporates, it pulls the heat out with it, making the inside
cold. It's a natural, cheap, easy-to-make refrigerator

Thanks to Chris Gupta for passing it on.
