Octahedral space frames and associated systems and methods

A concentrating solar collector assembly, comprising:

• an octahedral space frame, including:
• a plurality of double octahedral structures disposed in a first row in a longitudinal direction, adjacent ones of the plurality of double octahedral structures sharing two common members, the plurality of double octahedral structures collectively forming a V-shaped opening in the octahedral space frame, as seen when the octahedral space frame is viewed in the longitudinal direction,
• each of the plurality of double octahedral structures including respective first and second single octahedron structures joined in a transverse direction and sharing three common members, the transverse direction being orthogonal to the longitudinal direction;
• and
• a parabolic trough disposed in the V-shaped opening in the octahedral space frame.
