Weltevree’s Groundfridge is a prefabricated cellar that when installed, keeps a large amount of cheese, wine, fruit and vegetables cool without a requirement for electricity.
It’s capacity is that of about twenty conventional refrigerators. The temperature is said to go no higher than 50-53 degrees F, which is 10-12 degrees Celsius. It consists of a polyester shell which has an accompanying staircase and rail. It has a ventilation system, and when people are out, it is airtight and virtually vermin proof.
It is possible to have a builder build a similar device for you, although it would likely be more expensive than this particular device. An LED strip lighting package and a cabinet are options that may be added at extra cost. Shelving is standard. Floris Schoonderbeek is the designer and the recipient of the 2015 Danish design award for this device.
Information from Weltevree itself:
The Groundfridge is a buryable, autonomic operating (cooling) cellar. The Groundfridge uses the insulating capacity of the soil and the cooling effect of the underground water. This allows the temperature within the Groundfridge to remain a steady 10 – 12 °C ( 50-53 ºF) throughout the entire year – the perfect temperature to store, for example, fruits, vegetables, wine and cheese.
No electricity bill
Keeping your food stored chilly without using a refrigerator and thus without using energy? Not only is this possible, it is in fact based on an age-old principle. The Groundfridge has as much storage capacity as 20 refrigerators.
How does it work?
The Groundfridge is transported and delivered to you, dug in and covered up with the soil taken from its new lodging place. This covering layer of soil is about 1 meter thick and has ample insulating properties for a steady core temperature within the Groundfridge as the underground water provides additional cooling. Added benefit: installing the Groundfridge requires no permits, and when digging it in, no soil need be carried off of the premises.
20 refrigerator capacity, zero electricity
The Groundfridge has a storage capacity of 3,000 liters. This equals the contents of 20 refrigerators and will store 1,102 lbs (or 500 kg) of food (the harvest of a 250 m2 vegetable garden). That’s enough to prepare 350 meals – enough to feed a family of 5.
