A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

A concentrated solar power generation system includes a movable platform having a groove, a Fresnel lens located in the groove of the movable platform, a header located below the Fresnel lens, a plurality of heat collection tubes arranged in a circular array, a reflector with a tapered surface, and a support base. The header has a water circulation pipe, an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe each are communicated to the water circulation pipe. A lower end of each of the heat collection tubes is fixed on the support seat, and an upper end of each of the heat collection tubes contacts the water circulation pipe. The reflector is mounted on the support base and located in a space enclosed by the heat collection tubes.

A method of modulating the impact of electromagnetic irradiance on a predominantly enclosed space, including providing at least an inner shell of the predominantly enclosed space, placing a plurality of spatially adjustable functional elements in an exterior position relative to an outside facing surface of said inner shell and/or placing one or more panels, containers, or reservoirs, each including a thermal carrier medium, in or proximate to said predominantly enclosed space to increase the thermal capacity of the inner shell. A control system adjusts the position of the functional elements and/or the spatial distribution of the thermal carrier medium. The control system acquires data from one or more sensors and detects a catastrophic even related to the predominantly enclosed space.

A solar panel mounting system included a top hub and bottom hub comprising a receptacle in a center portion of the hub shaped to receive a pole and a plurality of attachment points affixed to an exterior portion of the receptacle, a girder assembly comprising: a plurality of top girders and a plurality of bottom girders each of the plurality of bottom girders being configured to be mechanically fastened the bottom hub at their proximal ends and each of the plurality of bottom girders being configured to be mechanically fastened to the plurality of top girders; and a plurality of mounting module purlins, wherein each of the module mounting purlins connect to at least two of the plurality of top girders, and wherein each of the plurality of mounting module purlins is radially connected to at least one other of the plurality of module mounting purlins.

A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.

A screw anchor for a trussed foundation system to support single-axis trackers and other structures and related methods of driving such a screw anchor into underlying ground. A hollowed tube of uniform diameter is open at both ends with a thread form beginning at one end and circumscribing a portion the tube, the thread form having a tapered lead-in. The open-ended geometry allows a mandrel or rock drill to be inserted and operated through the anchor during driving to expedite the driving process. The tapered thread form provides a lead-in for driving the anchor into a rock bore.
