A carbon nanotube 3 strut prism is proposed. The three carbon nanotubes are covalently tensioned, or tethered, at their cap pentagons by polyethylene polymer chains, by Needham, Wilson, and Yakobson.

The 3 strut prism can be used as a tripod, supporting an object. WV is a veteran user of tensegrity structures for camping. He has deployed tensegrity hammock stands. Below, a 3 strut tensegrity stand he built supporting a Bushcooker LT II stove. Photographed by WV while camping at Laurel Fork Wilderness, August 2010.

Multiplying The 3 Strut Prism

The 3 strut construction may be repeatedly applied to construct larger tensegrity structures.

Fuller created this pyramid of 3 strut tensegrities, yielding a 3x10 strut tensegrity. Photo, Stanford archive.

24x3 strut prism forming a bent torus

StructureMode, an engineering firm, repeatedly used the 3 strut prism to construct a torus that conforms with the perimeter of a hyperbolic paraboloid.

A torus, bent to support fabric, is formed by 24 3-strut tensegrity prisms. Vision at the London 2016 Exposition.

A 3 strut tensegrity has been constructed from DNA strands by Seeman's team. Below, a stereoscopic image.

Multiplying Each Strut in the Prism

In an alternate construction method, each structurally essential strut is repeatedly implemented. The new strut is redundant, structurally. Visually, the redundant struts articulate various forms as they apread out and away from one another. Pars experiments with this implementation; below two photos from his website.
