There are times when simplicity rules over sophistication.
The Zeer pot could not be simpler or easier to make or operate and yet as a refrigeration device it is truly an example of just how simplicity can work when sophistication cannot. It is a simple fridge made of local materials, clay and sand, consisting of one earthenware pot set inside another, with a layer of wet sand in between. As the moisture evaporates outwards from the wet sand through the outer earthenware pot it cools the inner pot, keeping up 12kg of produce fresh for up to three weeks. The shelf life of Tomatoes and Guavas are extended from 2 to 20 days, carrots from 4 to 20 days and Rocket from 1 to 5 days.
Fruit, vegetables and water are all kept fresher for longer – providing much needed help to starving families and can mean the difference between potential starvation and having enough food.
The Zeer pot is cheap, easy to make (see the video) environmentally friendly and works on Solar Energy. Now didn't Paul say something in Phillipians 4:19 about God meeting our needs?
