Coca-Cola - Bio Cooler

Some places it takes time to get some ice during a hot day. As a solution, Coca-Cola has invented a fridge, that doesn´t need electricity to operate. The evaporation after watering the flowers, cools another chamber and turns a gas into liquid, creating a cooling effect. The Happiness campaign brought some smiles into a Colombian village that did not have electricity to get refreshments in extreme hot weather.
