The way I'm understanding it, it is more difficult to build up heat in a small
composter, so the solar dome helps boost the internal temps. The outer area of the bin acts as an insulating layer, which also helps keep the temps up. The center of the bin is the composting chamber.
Moisture condenses under the dome, and it is sized so it drips back in at the outer perimeter where it waters the plants. The center where the
real composting is taking place is kept drier, so there is less need to
add dry material. (That's a real bonus because our kitchen waste is usually very moist.)
the dome doesn't cover the whole top of the composter so air is still allowed in.
I would guess that keeping rain off the main compost area is also a benefit, to prevent the nutrients from being washed away.
The plants root reach down to the bottom of the planter for the nutrients.
They say you can put worms in there, also. They avoid the heat in the center and so spend their time closer to the plants roots.
I'm thinking strawberries and cherry tomatoes would be perfect in this thing.
