| 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. | |
