Various apparatuses and methods are provided for measuring the likely environmental impact of a particular geographic location on power generation properties of potential solar installations at the particular location. In an example embodiment of one such apparatus, a measurement device is provided. The measurement device includes a base portion comprising a base frame element disposed on a plurality of supporting legs, and a top panel comprising a series of connected members and one or more measurement modules whose planar dimensions are defined by the series of connected members. The top panel is connected to the base portion by a joint such that the top panel can rotate about the joint, and a panel support element is configured to fasten the top panel immovably at a desired degree of rotation in relation to the base portion.

There is provided a renewable power generation farm for fishing work, the farm comprising: a plurality of mutually connected floating ships, wherein each ship is configured to generate an energy using solar and wind power, wherein each ship comprises: a main elongate floating structure; a wind-based energy generation device secured to the main elongate floating structure; a transverse beam extending perpendicularly to a longitudinal direction of the main structure; a longitudinal beam extending in a parallel manner to the longitudinal direction of the main structure; connection beams connecting both opposing ends of the transverse beam and both opposing ends of the longitudinal beam respectively; auxiliary pillars vertically extending through the both ends of the transverse beam and the longitudinal beam respectively; solar-based energy generation devices disposed at top ends of the auxiliary pillars respectively; and auxiliary elongate floating structures disposed at bottom ends of the auxiliary pillars passing through the ends of the transverse beam.

A driveline joint may include a driveline shaft that has a plurality of slots and a shaft coupling positioned in an interior of the driveline shaft in which the shaft coupling includes one or more openings with each of the openings corresponding to one or more respective slots of the plurality of slots included in the driveline shaft. The driveline joint may include one or more spherical bearings that are each positioned between an interior lateral surface of the driveline shaft and an exterior lateral surface of the shaft coupling and against one of the openings of the shaft coupling. The driveline joint may include one or more fasteners, wherein each of the fasteners extends through one of the slots and one of the openings of the shaft coupling.

A device for utilizing a surface, such as the surface of a floor, outside wall or roof, for a variable function, including a first functional element with an active surface area the size of at least a part of the surface, at least one second functional element with an active surface area the size of at least a part of the surface, and a rotatable carrier for varying, on at least a part of the surface, the functional element with which the surface is utilized. A method for utilizing a surface for a variable function is also shown.

A rotating, pivoting mount for mounting a panel is disclosed. The mount can include a mounting block, a driveshaft, and a base. A socket in the mounting block can be mounted on a ball of the base to pivotally couple the panel to a structure. The ball can also include a cam profile, while the mounting block can include a complementary cam follower. As the mounting block rotates, therefore, the cam follower can follow a path set forth by the cam profile to tilt the mounting block about one axis as the mounting block rotates about a second axis. In this manner, the panel can be rotated and tilted—or moved about two axes—using a single motor. The use of a single motor can, in turn, reduce the cost and complexity of the system, while maintaining high efficiency for the panel (e.g., a solar panel) mounted thereon.
