可口可樂綠色雪櫃   無電地區享冰凍汽水
大熱天時我們要飲一支解渴的冰凍可樂，只要打開雪櫃或者到便利店就可以。在哥倫比亞的城市 Aipir，當地氣溫往往高達攝氏 45 度，然而因為電力供應並不穩定，所以居民想用凍飲消暑絕不容易。可口可樂就間廣告公司聯手為當地人帶來毋須用電的 Bio Cooler 雪櫃，利用天然物料將飲品變冷。



Bio Cooler 利用兩種方式製冷，首先在雪櫃頂部種植植物，並且定時淋水，水份蒸發從而帶來降溫效果。然後再以鏡子反射陽光，激活一種能夠製冷的物質，令空氣變冷形成類似雪櫃的效果。片段介紹，放在 Bio Cooler 內的汽水可以降溫至只得 10 度。



Coca Cola uses the sun to cool drinks
In the town of Aipir, Colombia, the temperature can often get as high as 45ºC (113ºF), yet few of the residents have a reliable source of electricity. So, pulling an ice-cold beverage out of the fridge isn't really an option. Coca Cola and the Leo Burnett Colombia advertising agency therefore devised a "Bio Cooler" for the town – it reportedly chills cans of Coke, without using electricity.
The cooler was developed in collaboration with the International Physics Centre in Bogota, and is described solely in a short video released by Leo Burnett. It reportedly works by two methods ...

First, a compartment in the top of the cooler contains plants and soil, while the cans of Coke sit in a chamber below. When the plants are watered and much of that water subsequently evaporates, it has a cooling effect on the chamber.
Second, a mirror in the cooler focuses heat from the sun, which is somehow used to convert an unnamed gas to a liquid state, creating a cooling effect as that liquid is circulated around the Coke chamber. This could conceivably be something like a thermal-powered version of the CryoEnergy System, in which energy is stored by converting ambient-temperature gaseous air into cold liquid air.
