Abstract: A portable, handheld exercise device comprises a spherical outer shell with multiple parallel handles mounted to the outer surface thereof containing a rotating mass therein. An inner shell located within is spaced from but attached to the outer shell. A gyroscopic energy-generating structure (GEGS) is located within the inner shell. The GEGS comprises a rotating disc or a rotating mass configured to simulate a rotating disc. The rotating disc or a rotating mass is powered to spin around a rotational axis orientated in a preselected orientation to the multiple parallel handles. When the one or more handles of the exercise device are held by an individual the spinning characteristics of the rotating disc or mass creates a force against the user's hands. An internal or external controller allows the user to vary the spinning characteristics of the spinning mass and the level and intensity of the resultant exercise provided to the user in counteracting the forces created.

Abstract: Provided are systems and methods for a wind-powered electrical generation and fluid pumping device, including: a drive shaft; a generator comprising a rotor, wherein the generator may be coupled to the drive shaft by means of the rotor; and at least one vane pair, the vane pair comprising ribs and a structural twist, wherein the at least one vane pair is attached to the drive shaft by screws and square washers and further wherein vane extensions may be attached to the at least one vane pair with rivets. The vertical wind-powered electrical generation device is also described. It utilizes unique improvements of shaft coupling (to generator and rotor), the strengthening of complete Savonius rotor system, and ease of assembly. The vane pairs may be a segmented Savonius rotor. They may also create a helix pattern as they are installed.
