Groundfridge keeps food fresh, no electricity required

• http://www.gizmag.com, By Adam Williams

The prefabricated Groundfridge uses the earth's own insulating properties to keep food fresh, no electricity required.

Of course, root cellars aren't a new invention by any means, but the Groundfridge looks well-built and relatively easy to install. Weighing in at 300 kg (661 lb), and measuring 2.28 m (7.48 ft) in diameter, the prefab cellar is built from hand-laminated polyester and ships with integrated cabinet and lighting. Access is gained by a hatch-like door and steps lead into the cellar proper.

Weltevree rates Groundfridge's storage as equivalent to around 20 typical refrigerators and says that it can store the harvest from a 250 sq m (2,690 sq ft) vegetable garden, or 500 kg (1,102 lb) of food. The firm further states that Groundfridge maintains a steady temperature of between 7 to 15º C (44.6 to 59º F), even if the temperature upside varies anywhere between -10 to 35° C (14 to 95° F)
