A fridge that works without electricity, here is an alternative to our good old traditional fridge! How is this possible? As long as you have a little piece of garden and you can bury it? Explanations.
Che underground refrigerator was designed by designer Floris Schoonderbeek, of the company Weltevree in Holland. Built by digging a simple hole, it can be installed in any soil and requires no specific building permit and can be used as a cellar or refrigerator.
How does it work?
The Ground Fridge uses the insulating effect of the earth and the cooling effect of the water table. Whether it's freezing or very hot outside, the temperature in the fridge remains stable throughout the year between 10 and 12°C, which is the ideal temperature for storing fruits, vegetables, wine and cheese. Up to 3000 litres of food can be stored here.
Spherical in shape, it is buried and covered with excavated earth. This layer of earth is one meter thick and insulating, allowing the temperature inside the refrigerator to hardly vary.
It can also be seen as an innovative version of our grandmothers' pantry or the traditional cellar... ecological since it works without electricity. Selling price: 7 450€ to date.
This innovation was nominated for the Dutch Design Award which rewards the innovations of Dutch designers.
