The Boxcooler is a refrigerator in a backpack by designer Sebastian Bertram. It has room for both food and dishes and "thermoelectric Peltier elements replace the traditional “freezer batteries” which defrost after a while. Therefore, the food inside stays fresh and cool for a longer time. They are supplied by a storage cell which can be reloaded inside the car or at home." Sweet, this Sebastian character might be on to something
