The enclosure of this biodome, then, would be shaped as durably as possible, with a dome
overhead, an inverted-dome foundation below, and a curved vertical wall connecting the
perimeters of the two domes, as shown in (Fig. B), (Fig. C), (Fig. D), and (Fig. E).
When properly constructed, then, the shape of this enclosure is the strongest building shape there
is against every type of live load or dead load, including lateral loads, vertical loads, bending
forces, and shear forces. This is because this enclosure is entirely non-developable. In other
words, the structure cannot be flattened or bent in any direction without ripping or tearing. And
considering that the structure would be built entirely of a high-strength steel or alloy that would
exhibit high toughness, this is not likely to happen. Furthermore, all walls and floors of the biodome
would be completely interlocked with the perimeter wall of the biodome, thereby acting as vertical
and horizontal structural ribs that would strengthen the perimeter wall beyond its own capacity as a
structural membrane. So, with this type of perimeter structure in place at the base of the dome
overhead, all loads that the dome would place on the structure would be resisted readily.
The enclosure of this biodome, then, would be built mostly of curved panels that measure no more
than 12-square, because, at this size, the panels could be cast of a high-strength, noncorrodible
steel or alloy that otherwise could not be cast into buildable parts because of their larger size.
These panels, then, would interlock in a way that would give maximum structural integrity to this
enclosure, enough, in fact, for the enclosure to span distances of 1,000-feet or more. To add,
these panels would be interlocked together in a way that would eliminate visible seams, so that all
the water and air of the biodome would be prevented from escaping the enclosure, and so that
there would be no seams for ice to form in, thereby permanently eliminating freezing and thawing
