What is a Walipini?

What is a walipini?  It's not an exotic animal from down under and it is also not a hybrid between a watermelon and a zucchini.

It can best be compared to an earth contact home. The Walipini is dug down into the earth about eight feet, facing the winter sun and covered with a plastic-sheathed roof angled at about forty degrees.

And it can be used to grow crops all winter long.
