You know how it is, it’s hot and you are thirsty! To make things even worse the only drink you have with you is a can of something fizzy that is warm, what a nightmare! However, not if West Coast Chill has their way, as they have developed a can that uses a built in heat exchange unit (HEU) that at the press of a button turns warm drinks into ice cold drinks, now you are talking!
According to their website, this how the West Coast Chill can actually works;
It has long been desired to provide a simple, effective and safe device, which can be housed within the food or beverage container for the purpose of cooling or heating the food or beverage on demand. In many instances ice or refrigeration is not readily available in locations such as camping, boating, fishing, beach, etc. In a Self-chilling beverage can such as West Coast Chill, the beverage can has a built in Heat Exchanger Unit (HEU) which uses a C-CO2 adsorbent-desorption system to cool the beverage in the can. The HEU has CO2 gas adsorbed to activated carbons at 10bar.
