The Coca-Cola Bio Cooler uses heat from the sun to cool stored items, in two different ways. Firstly, water poured onto a plant housed at the top of the cooler is evaporated, which cools the chamber situated below. Secondly, sun heat is captured by a mirror, which is used to turn a particular gas into liquid, creating an even greater cooling effect.
Interestingly, when Coca-Cola’s latest innovative device becomes hotter, it cools better. The new cooler was recently trialled in the small Colombian town of Aipir, where temperatures can reach as high as 45ºC.
