In Namibia, Miss Emily Cummins is known as “The Fridge Lady”. This is because she invented a solar-powered refrigerator that is can help many poverty-stricken Africans.
The solar-powered refrigerator works with two cylinders, one inside the other. The inner cylinder is metal while the outer one is wood or plastic. In between these two cylinders is either sand or soil, which can be soaked with water. The sun’s rays heat the wet material, and as the water evaporates, the heat is removed from the inner cylinder. This keeps the fridge at a cool six degrees Celsius.
This solar-powered fridge could easily change the world as we know it. Now perishable goods such as meat and milk can be stored for days in areas where there is no grid electricity. Miss Cummings spent a lot of time in Africa showing the people her invention.
This is pretty cool (excuse the obvious refrigerator pun) considering that Emily Cummins is still in her early twenties. She has won awards for some of her other inventions including a toothpaste squeezer for arthritis sufferers and a water carrying device, also for use in the Third World.
She is a graduate of Leeds University, and was once refused a place on an engineering course because “she didn’t have the correct qualifications”. She qualified now?
