A COOL WAY TO KEEP FOOD FROM SPOILING

 

 

A few degrees can make a big difference when it comes to food storage.

Foods can go bad if they get too warm. But for many of the wolds´poor,

finding a good way top keep food cool is difficult.Refigerators are costly

and they need electricity.

 

 

Yet spoiled food not only creates health risks but also economic

loss. Farmers lose money when they have to through away

products that they cannot sell quickly.

 

But in nineteen ninety-five a teacher in Northern Nigeria named

Mohammed Bah Abba found a solution. He developed the Pot- in- Pot

Preservation/Cooling System .It uses two ground containers

made clay. A smaller pot is placed inside a larger one. The space

Between the two pots is filled with wet sand .The inner pot can be filled

with fruit, vegetables or drinks, A wet cloth covers the whole cooling

System.

 

Simple evaporation process. Water in the sand between the two pots

evaporates through the surface of the larger pot, where dryer outside air

is moving.

 

The evaporation process creates a drop in temperature of several

degrees .This cools the inner pot and helps keep food safe from harmful

bacteria. Some foods can be kept fresh this way for several weeks.

 

People throughout Nigeria began using the invention. And it

became popular with farmers in other African countries.  Mohammed Bah

Abba personally financed the first five thousand pot-in-pot systems for his

own community and five villages nearby.

 

In two thousand, the Rolex Watch Company of Switzerland honored him

with the Rolex Award for Enterprise.  This award recognizes people trying

 to develop projects aimed at improving human knowledge and well-being.

 

A committee considers projects in science and medicine, technology, exploration and discovery,

the environment and cultural history.

Winners receive financial assistance to help develop and extend their projects.

 

The award is given every two years. The next one will be given in two thousand eight.
