Mohammed Bah Abba
Mohammed Bah Abba (1964–2010) was a teacher from northern Nigeria who developed the pot-in-pot refrigerator in the 1990s. This refrigerator is extremely simple and does not require power, making it suitable for use in desert environments without easy access to electricity or repairs. It consists of a small glazed earthenware pot placed inside a larger unglazed one, with the space between the two filled with moist sand. The inner pot is filled with whatever is desired to be cooled (fruit, vegetables, drinks) and covered with a wet cloth. The evaporating water draws heat from the inside through the porous outer pot, cooling the interior by up to 14°C. Abba hailed from a family of potmakers and tapped into the large underemployed local workforce for the project. Local pot-makers he hired produced the first batch of 5,000 pot-in-pot refrigerators. He received the Rolex Award for Enterprise Rolex SA () is a British-founded Swiss watch designer and manufacturer based ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pot-in-pot Refrigerator
A pot-in-pot refrigerator, clay pot cooler or zeer ( ar, زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the outer liquid draws heat from the inner pot. The device can cool any substance, and requires only a flow of relatively dry air and a source of water. History Many clay pots from around 3000BC were discovered in the Indus Valley civilization and are considered to have been used for cooling as well as storing water. The pots are similar to the present-day ''ghara'' and ''matki'' used in India and Pakistan. There is evidence that evaporative cooling may have been used in North Africa as early as the Old Kingdom of Egypt, circa 2500BC. Frescoes show slaves fanning water jars, which would increase air flow around porous jars to aid evaporation and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Region, Nigeria
Northern Nigeria was an autonomous division within Nigeria, distinctly different from the southern part of the country, with independent customs, foreign relations and security structures. In 1962 it acquired the territory of the British Northern Cameroons, which voted to become a province within Northern Nigeria. In 1967, Northern Nigeria was divided into the North-Eastern State, North-Western State, Kano State, Kaduna State, Kwara State, and the Benue-Plateau State, each with its own Governor. History Prehistory The Nok culture, an ancient culture dominated most of what is now Northern Nigeria in prehistoric times, its legacy in the form of terracotta statues and megaliths have been discovered in Sokoto, Kano, Birinin Kudu, Nok and Zaria. The Kwatarkwashi culture, a variant of the Nok culture centred mostly around Zamfara in Sokoto Province is thought by some to be the same or an offshoot of the Nok.
