SELECTED IDEAS OF BUCKMINSTER FULLER
TETRAHEDRA: DOUBLE
COUNTER-TETRAHEDRONAL ANCHORING

In 1963 Fuller patented a method of anchoring structures so that they were horizontally stable under all conditions.

He arranged two sets of tetrahedronally shaped anchors in such a way that they counter-torqued each other.

The anchored structure could thus move in and out, but not laterally.

For example, he foresaw the day when large passenger and cargo

submarines would need to make transfers in mid-ocean.

 -
To that end, he designed large floating sub-surface ocean islands.
