The Groundfridge by Weltevree is the best thing since the root cellar and this is how it works.
Dutch company Weltevree has developed the Groundfridge as a new-age alternative to the old dug-in-the-ground root cellar. With the same capacity as 20 refrigerators the Groundfridge not only has a great deal of space, but can do the job without electricity.
This innovative polyester 'globe' was nominated for the Dutch design award in 2015 and may be for sale in the US by early 2017. Here's what it looks like to install it, use it, and how it appears in your yard:
At a steep, estimated price of around $16,000 this "fridge" is probably best suited for upscale users. Issues like groundwater (water table) and rock would certainly put a damper on this good idea.
Before we start to poo-poo the idea let's remember that it's very clean, unlike a traditional root cellar, and uses zero electricity. While the design doesn't allow it to store meat it will keep fruits and vegetables safe as well as your favorite drinks.
The best use for the Groundfridge would be a community garden or anyone with enough land and money to install one. Let's hope that this will find its way into the hands of the less fortunate perhaps via local government or charitable donation.
