Abstract: The present invention is directed to wind turbine blades that include an additive manufactured system-integrated tip. The disclosed wind turbine blades reduce the levelized cost of electricity (LCOE) for both new and existing wind turbines.

Abstract: The present disclosure is directed to towerless vertical-axis wind turbines with pre-tensioned rotors. The present disclosure is further directed to a vertical-axis wind turbine (VAWT) with supported blade ends (e.g., Darrieus type) which replaces the center tower with tensioned supports, such as tensioned guy wires, and blade pre-load.

Abstract: An ambidextrous magazine release for a firearm is provided. The magazine release may include a release rod configured to be operably coupled to the firearm, and a lever operably connected to the release rod and rotatable relative thereto. A portion of the lever may be configured to engage a magazine received within the firearm. When a first force in a first direction is applied to the release rod, the release rod may move the lever to cause the lever to disengage the magazine. When a second force in a second direction is applied to the lever, the lever may rotate relative to the release rod to disengage the magazine.

Abstract: Various technologies described herein pertain to a vertical axis wind turbine blade configured to rotate about a rotation axis. The vertical axis wind turbine blade includes at least an attachment segment, a rear swept segment, and optionally, a forward swept segment. The attachment segment is contiguous with the forward swept segment, and the forward swept segment is contiguous with the rear swept segment. The attachment segment includes a first portion of a centroid axis, the forward swept segment includes a second portion of the centroid axis, and the rear swept segment includes a third portion of the centroid axis. The second portion of the centroid axis is angularly displaced ahead of the first portion of the centroid axis and the third portion of the centroid axis is angularly displaced behind the first portion of the centroid axis in the direction of rotation about the rotation axis.

Abstract: An adjustment mechanism selectively attachable to a rifle. The adjustment mechanism includes a riser body configured to be operably connected to a butt end of the rifle and a butt plate rotatably connected to the riser body. The butt plate is configured to be selectively rotated between at least a first position and a second position relative to the riser body. In some instances the butt plate attaches to a butt pad of the rifle and as the butt plate rotates between the first position and the second position, the butt pad rotates correspondingly. The adjustment mechanism also includes a cheek piece rotatably supported above the riser body and selectively rotatable relative to the riser body between a support position and a release position and in the support position the cheek piece extends along a top surface of the rifle and in the release position the extends along a side of the rifle.
