A dome greenhouse has the advantage of minimal shading caused by the strong, efficient dome structure. Maximizing sunlight into a greenhouse is often more important than minimizing the loss of heat out of the greenhouse.

The Pillow Dome, pictured here in 1982, admitted maximum light and was also well insulated with three-layer inflated pillows. The high, open interior space included tall fish pond, a large fig tree, and vegetable beds.
