A simple idea can change lives. We are talking about the solar fridge created by the 21 year old Emily Cummins as part of her school project. We hear, the fridge is now improving lives in Africa. And this isn’t the first time Cummins noble ideas have made a difference. Earlier too, she came into the limelight with her toothpaste squeezer for arthritis patients and the water carrying device.

The fridge in reference is sustainable and is based on the principle of evaporation. It is effective in storing perishable goods like milk and meat cool for days together at a temperature of 6 degrees; that is without using and power.
 
You will find two cylinders in the fridge, one inside the other. The inner cylinder is made from metal while the outer one can be made from anything at hand like even wood and plastic. Cummins said that her inspiration came from the human body itself; how we cool biologically We are impressed!
