The brand's Bio Cooler does not need electricity.

Coca-Cola worked with Leo Burnett Colombia on the Bio Cooler Project to bring cool drinks to parts of the world that have extremely hot weather without a regular power supply.

The Coca-Cola Bio Cooler is a fridge that does not need electricity to function. The design of the cooler is based on ancient tech that cools air through water evaporation, so it works even better the warmer it gets.

The Bio Cooler is a rectangular device with four legs and an array of small plants on top of it. Its “cooling” system works two ways. First, when the plants are watered, the evaporation that occurs cools another chamber. Second, the heat of the sun is captured by a mirror installed in the device and is used to turn a gas into liquid – which creates an even higher cooling effect.
