Coca-Cola invented a refrigerator that works without electricity.

HOW MUCH MORE HEAT MAKES, WORKS BEST NOW THAT THE COOLING METHOD WORKS CONTINUOUSLY FROM THE IRRIGATION OF THE PLANTS AND EVAPORATION.

Bio Cooler, the ecological Coca-Cola cooler, It is much more than a striking invention that it seeks to promote the popular drink even more, If it is worth.

Its use in hot areas, almost uninhabitable, where does the electricity, It manages to work the miracle of self-sufficient cool cans. It makes it almost by magic, Thanks to an ingenious system that takes advantage of high temperatures in their favor and that, in the future, It could even change the shape of food preservation.

One of those remote places is Aipir, a Colombian village that keep food fresh supposed to do endless journeys of a minimum of 12 hours to bring ice. Just, thinking in this town, one of the hottest in the country, Coca Cola created this fridge that does not require electricity to operate and, made once, He gave it to Aipir for use and enjoyment of its inhabitants.

The operation of the machine, a practical portable fridge on four legs cover plants on top, It relies on leverage this extreme heat, taking advantage of the steam of water or evaporation and the Sun captured by small solar panels to cool its interior.

The gadget has been developed by Leo Burnett Colombia and the International Physics Centre in Bogota. The invention uses the old system used by ancient cultures used plants and damp earth to keep fresh foods in ceramic Chambers.

The eCool is another witty beverage cooler which is also inspired by ancient traditions. Invented by a Danish Youth, It keeps fresh cans within a subterranean fridge provided by nature itself.

As the Cooler Bio, the eCool needs no electricity. It keeps the cans cool throughout the year taking advantage of the low temperatures of the Earth's interior, an idea which is linked to the habit of storing food in cellars or caves. In this case, a one metre hole is dug to install the equipment, that keeps fresh up to 24 cans of beer or other drink in the garden.

With projects such as the Bio Cooler and new dresses to paint green Coca Cola always, However, It is clear that the ecological and solidarity are in fashion. A greener planet is trend, Fortunately, but the truth is that only when the change is substantial sense.
