£15,000 subterranean 'ground fridge' keeps food cool all year round

A subterranean 'ground fridge' can naturally cool your food without needing a mains supply from your home – but it will set you back a whopping £15,000. Its interior temperature is affected by local factors such as soil type, groundwater levels, exposure to sunlight, mound vegetation and the average outside temperature The Groundfridge is apparently designed for storing wine, general provisions or fruit and vegetables grown in your own garden - and it has a lock on the door to keep intruders from helping themselves The colour of the fridge's door is green 'so it will merge in the landscape', while the body of the fridge is white to help reflect light. The Groundfridge is fitted with a battery-driven ventilator that gives the option of setting ventilation times to the user's desired specifications The giant cooler, which needs no electricity and has a 3000-litre storage capacity, has four shelves that go around its spherical interior, although it can be ordered without these at a cheaper price The colour of the fridge's door is green 'so it will merge in the landscape', while the body of the fridge is white to help reflect light No soil needs to be disposed of when installing the Groundfridge, which can also be buried underneath sand. The company says: 'The lightweight Groundfridge is very easy to transport and install and placing it doesn’t require any permits' No soil needs to be disposed of when installing the Groundfridge, which can also be buried underneath sand According to the Dutch firm, the interior temperature of the Groundfridge is affected by local factors such as soil type, groundwater levels, exposure to sunlight, mound vegetation and the average outside temperature in the country it's installed in. Unsuspecting visitors to your back garden may get a pleasant surprise when they open the door to a secret pod filled with tasty produce The company calls the Groundfridge 'an innovative version of the traditional root cellar for today’s sustainable companies and cosmopolitans with their own vegetable garden who lead modern, self-providing lives'
