Abstract: A fishing lure device including a weight, a weight shaft extending from the weight and terminating in a shaft eye configured for attachment of a fishing line, and a hook having a hook eye that encircles the weight shaft between the weight and the shaft eye, wherein the hook eye is freely rotatable around the weight shaft. The shaft eye may have a diameter larger than an internal diameter of the hook eye such that the shaft eye retains the hook eye on the weight shaft. A bait may be attached to the hook. The bait may be a buoyant elastomeric lure configured to maintain an upward orientation when the weight rests on a bottom substrate. The freely rotatable connection between the hook eye and the weight shaft permits the hook to move independently of the weight in response to water currents.

Abstract: A thermal energy storage device for use in a pulsed power supply to store waste heat produced in a high-power burst operation utilizes lithium hydride as the phase change thermal energy storage material. The device includes an outer container encapsulating the lithium hydride and an inner container supporting a hydrogen sorbing sponge material such as activated carbon. The inner container is in communication with the interior of the outer container to receive hydrogen dissociated from the lithium hydride at elevated temperatures.
