The present technology is directed generally to phase change materials for cooling enclosed electronic components, including for solar energy collection, and associated systems and methods. In particular embodiments, a system directs warm air through an airflow path in thermal communication with a phase change material to liquefy the phase change material and cool the air. The system also directs the cool air into thermal communication with electronic components to cool the electronic components via conduction and/or convection.

A solar tracker bearing assembly has a rotating element sandwiched between two mounting brackets and held together by fasteners. The rotating element includes an arc-shaped slot such that the rotating element can pivot against the fixed mounting brackets. Bearings may be positioned within the arc-shaped slot. The rotating element can be configured to accept toque tubes of various cross-sections.

Supports for suspended solar enhanced oil recovery concentrators and receivers, and associated systems and methods. A representative solar concentrator system includes a curved reflective element oriented concave relative to a focal line, a curved first rib member carrying the reflective element and oriented concave relative to the focal line, a curved second rib member oriented convex relative to the focal line, and a plurality of cross members coupled between the first rib member and the second rib member. In further embodiments, the system includes a bearing having an inner bearing element in rotational contact with a concentrator attachment member, which supports a solar concentrator. A receiver interface member is fixedly engaged with the inner bearing element, and a receiver attachment member is pivotably connected to the receiver interface member. A biasing element biases the inner bearing element against the receiver.
