Abstract: A reflective concentrator can include a primary reflector and a secondary reflector located radially outward of the primary reflector. The primary reflector can be a rotationally-symmetric, convex conical shape, radial sections of which may include an off-axis parabolic reflector with a focal point radially outward of the primary reflector. A secondary reflector may be located radially outward of the primary reflector, and may include a rotationally symmetric section of a toroidal space surrounding the primary reflector. In some embodiments, the secondary reflector may be convex or concave. Incident sunlight generally aligned with a rotational axis of symmetry of the primary reflector may be reflected off of the primary reflector, off of the secondary reflector, and back towards a point near the central peak of the primary reflector. The reflective concentrator may be aerodynamically stable, and may include an aerodynamic fairing on its read side to further increase the aerodynamic stability of the structure.

The modules are movable between travel, intermediate, and deployed configurations. The travel configuration includes the longitudinal axes and the movement corridor being substantially parallel, and the openings being covered. The intermediate configuration includes the longitudinal axes being substantially perpendicular to the movement corridor, the junction sides facing each other, and the openings uncovered.

Abstract: Detecting a level of current in a conductor such as a power line can be accomplished using sensing devices that are coupled to the line. Such devices can have a clamshell or briefcase-style shape and close about the line. The line passes through a channel between the sides of the device. A quantum substance made of a material having a phonon decay sideband is arranged nearby the channel, and a light source and a scanning source work in tandem to cause the substance to emit light that can be analyzed to determine a magnitude of a magnetic field on the substance. By distributing such sensing devices about a grid or other electrical distribution network, current throughout the network can be collected and analyzed to ascertain the presence and location of interferences with the grid.
