Behold Coca-Cola's newest happiness machine: the Bio Cooler, a soft-drink dispenser that doesn't need electricity or batteries to operate.
The unit, developed by Leo Burnett Colombia and the International Physics Centre in Bogota, uses two cooling methods based on ancient technology. Watering the plants atop the device produces evaporation, and a mirror at the top is used to convert gas into liquid inside the cooler. Coke claims the cooler works better the hotter it gets, and the brand chose to demonstrate in Aipir, Colombia, where temperatures can approach 115 degrees Fahrenheit and residents travel 12 hours to fetch ice.
