The geometrics of this protective enclosure are well designed. By narrowing the top exposure, wind and night sky radiant cooling are reduced. By maximizing ground exposure, warmth radiating from the soil is captured at an increased rate.
So for me, it appears to be based on sound theory. Actual field conditions may confirm, or refute the concept.
As I look at the photo in greater detail, I see there's a floor on the bottom. This would block the warmth from the soil. I believe this may not be as practical as I originally thought.
The design may be eye catching for marketing purposes. A bit like designing fishing lures to catch the eye of the angling customer more than the actual fish.
