The Bio Coca-Cola Cooler Doesn't Require Any Power to Chill Drinks

— June 5, 2014 — Eco
The Bio Coca-Cola Cooler Project was developed with the aid of Leo Burnett Colombia and the International Physics Centre in Bogota, aimed at bringing refreshing beverages to extremely hot parts of the world that are without access to power.

Instead of electricity, the Bio Cooler puts an old technology to use, making use of cooling through water evaporation, which actually means that the hotter it is, the cooler the fridge is able to be. The Bio Cooler cools in two parts, starting with an evaporation system that comes from watering the plants atop the cooler are watered, and second, an internal mirror turns the heat of the sun from gas into liquid.

The Bio Cooler was tested in La Guajira, an area where going to get anything iced or chilled usually takes a full day.
