Abstract: An exercise device for exercising at least one of a human hand, wrist, and forearm, may include a pair of handles that rotatably mounted within sockets by exerting a force that can be adjusted. Further, levers may be pivotably mounted relative to handles to facilitate developing grip strength. Further, a vibrational force may be delivered to at least one of the handles to promote bone and muscle generation and inhibit their loss.

Abstract: A solar collection device includes a solar energy collector assembly being received and supported by a base. The solar energy collector assembly includes: a plurality of lenses secured within an elongated holder. Positioned concentric to the axis of the holder is a cylindrical glass shroud through which a tube passes. A first end of the tube, which is preferably formed of a high thermally transmissive metal, receives a supply of water, which is heated within the evacuated glass shroud by sunlight passing through the lenses and being focused onto the tube. The solar collector assembly is rotatably mounted to the base and may be caused to rotate at a slow speed by a drive means, or may be rocked at a slow speed. The elongated holder may be cylindrical, or may have a polygonal cross-sectional shape, with lenses staggered along each side of the holder to increase collection capability.
