Schoonderbeek's Groundfridge for Weltevree,
This spherical refrigerator is buried underground, keeping food cool without using electricity.
Groundfridge is based on traditional root cellars – spaces dug into the earth to preserve food and drink. It is designed to be buried underground where, due to thermal inertia, temperatures are constant throughout the year.
According to Weltevree, burying the fridge allows it to remain consistently between 10 and 12 degrees celsius throughout the year, meaning it can be used to store produce such as vegetables, wine, or cheese.
The company claims the storage capacity is comparable to that of 20 standard refrigerators, meaning it can hold up to 500 kilograms of food.
Constructed from lightweight laminated polyester, the Groundfridge is resistant to intrusion from roots of nearby trees or plants.
