A shape memory alloy can operate at very high temperatures in excess of that produced by the dog bone. It may the possible to build a mechanical device that produces a sharp pressure increase in the hydrogen gas to activate increased LENR reactivity through nanoparticle creation via supercritical pressure induced gas nucleation.
We might design a mechanical muscle that rapidly contracts added by leverage to produce the pressure wave then relaxes slowly to make the next pressure cycle possible. Shape memory acts in a limited temperature range. A small electric current can heat the shape sensitive material above its transition point to activate an explosive pressure pulse much in the way that the mantis shrimp uses contracting mussel power to produces cavitation bubbles to kill its prey. These smashers deliver the fastest punch of any animal <http://blogs.discovermagazine.com/notrocketscience/2008/07/19/the-mantis-shrimp-has-the-worlds-fastest-punch/>. As the club unfurls, its acceleration is 10,000 times greater than gravity. Moving *through water*, it reaches a top speed of 50 miles per hour. It creates a pressure wave that boils the water in front of it, creating flashes of light (shrimpoluminescene <http://en.wikipedia.org/wiki/Sonoluminescence> – no, really) and immensely destructive bubbles <http://en.wikipedia.org/wiki/Cavitation>. The club reaches its target in just three thousandths of a second, and strikes with the force of a rifle bullet. We just need to put a few of the pieces together.
