Mohammed Bah Abba
Mohammed Bah Abba was a man from Nigeria who invented a special kind of refrigerator that doesn't need electricity. You know how your mommy puts ice cubes in her drink to keep it cold? Well, Mohammed's invention works like that!
Here is how it works: Mohammed's refrigerator has two clay pots. The bigger pot has some sand in it, and is placed inside an even bigger pot. The space between the two pots is then filled with wet sand. When water evaporates from the sand, it makes the inside of the bigger pot really cold! So when you put your fruits or vegetables in the smaller pot and cover it with a damp cloth, it will stay cool for days without electricity.
This invention is really helpful for people who live in hot places without electricity, because they can now keep their food fresh without having to go to the market every day. It also helps them save money because they don't need to buy ice blocks or generators to keep their food cold.
