This eco fridge demonstrates the newest technology is not always the most disruptive. Evaptainers are "sustainable refrigeration units" that use an ancient cooling method to keep your food from spoiling.
The electricity-free refrigerators only require sun and water to work. The 4000 year old non-electric refrigeration technology also renders the appliances mobile, making it easier to keep food fresh for longer when you are on the go. The portable eco fridge has water between two containers that evaporates, which also removes the heat from the inside container. This is capable of keeping contents 35 degrees Fahrenheit cooler than they would be outside.
The lightweight, flat pack design will likely appeal to campers and hikers in addition to less developed communities where food security is an issue.
