While researching the refrigerator
root cellar I came across an interesting concept known as a spiral
root cellar. This design is for folks with very little space who
want to have easy access to their chilled products. Most versions seem
to be installed in the kitchen floor with a trap door for access. This
solution seems to be only available in Europe, and it's not cheap.
About 12 thousand dollars, which in the long run would be cheaper than
an expensive wine cooler thanks to the fact that it uses the earth for
cooling. Of course I'm wondering if some modification can be made to be
able to build one yourself, but I think we will be sticking with the
refrigerator root cellar design for now.
