Abstract: A power generating system for operating below a surface of a body of water includes a fuel cell stack configured to react hydrogen and oxygen to produce electricity. An oxygen source is configured to provide oxygen to the fuel cell stack. A hydrogen source is configured to provide hydrogen to the fuel cell stack. The hydrogen source is at least partially submerged in water and incorporates a non-hydride metal alloy that reacts with water to produce hydrogen from the water.

Abstract: A hand tool comprising first and second jaw members and first and second handle members, the first handle and both jaw members being cooperatively connected by a force multiplying linkage system. A force applied to the first handle drives the linkage system to close the jaws to crimp or cut a work piece. In one embodiment of the invention, a link in the linkage system has a first end movable between first and second positions relative to its first end pivot pin wherein the first and second jaw members close a first distance when the link first end is in the first position and close a second distance when the link first end is in the second position. Other embodiments comprise other step-wise changes in distance between force-bearing pivot locations in the linkage system to close the jaws progressive distances with successive closures of the first and second handles.
