    • A space frame connector is provided for attaching an oblique strut tube to an axial chord of a space frame. The space frame connector includes a collar adapted to fit over an axial chord. The collar is equipped with one or more attachment flanges. The space frame connector also includes a strut tube having an extrusion flange formed in at least one of its ends. The extrusion flange is made up of two parallel leaves that define a slot between them. The slot is sized and shaped to fit over an attachment flange on the collar that is positioned over the axial chord. The extrusion flange can be formed using simple press and punch tools. Space frames used to support solar energy collector arrays can be assembled in the field, including formation of the extrusion flanges on the oblique strut tubes, or multiple strut tubes can be attached to axial chords and compactly packed and transported to the field for use in constructing space frames, for example for supporting large parabolic trough solar collectors.

    • Described herein are linear receivers for use in concentrating solar collection applications. For example, linear receivers incorporating a volume displacement element within an internal volume of a linear solar radiation absorbing element are provided. The volume displacement element provides, for example, enhanced heat transfer characteristics between the absorber element and the heat transfer fluid, efficiency improvements associated with maintaining a position of the linear receiver at an optimal location for absorbing concentrated solar radiation and/or the ability to recover the linear receiver from a freeze event. Also provided are methods for making a linear receiver, methods for collecting concentrated solar radiation, methods for recovering a linear receiver from a freeze event, methods for improving overall receiver efficiency, such as by reducing bowing/sagging of the receiver element, and methods for reducing a circumferential temperature distribution of the absorber element.
