Re: [Vo]:Nitinol heat engine
Although there's no doubt some compression of any loaded deuterium in the nitinol system, I suspect that mechanical deformation of the nitinol by way of electrical impulse will not be sufficient to bring deuterons close to one another or to lattice sites by many orders of magnitude. (One of the reasons I like electric arcing as a motive force is that perhaps it could be strong enough to do something like this for the brief lifetime of the arc.) Eric

CB Sites, Yes, nitinol does not hold up well to hydrogen loading. I did several electrolysis experiments with it in 2012/2013 with H. Thicker wire held up better. You can see a video of one of the experiments here: http://www.lenr-coldfusion.com/2013/01/23/automated-android-electrolysis-system-nitinol-demonstration/ I was trying to do the same thing (load hydrogen and induce contraction).

Re: [Vo]:Nitinol heat engine
I don't believe that nickel or titanium can be loaded with hydrogen. Is such loading even possible?

Re: [Vo]:Nitinol heat engine
Axil, unless there is some limit on loading your talking about, both Nickel and titanium will load hydrogen/deuterium into their lattice. Titanium was what Steve Jones first used in his first CF experiments because it would load more deuterium than palladium greater than one I believe. . Nickel doesn't load deuterium at all though, but would load hydrogen up to 0.8 H/Ni. Correct me if I'm wrong. Anyway nitinol does load hydrogen just a little too well. What ever causes nitinol's shape metal properties disappears has hydrogen concentrates in the lattice.

It's still not a bad idea, but we just need a material that doesn't get brittle after hydrogen or deuterium loading. I'm clueless as to what that would be.

Very interesting comment on Rossi's blog passed along to me by a friend. Watch the nitinol heat engine video. 1. gaby de wilde March 11th, 2015 at 8:55 AM http://www.journal-of-nuclear-physics.com/?p=874cpage=9#comment-1061270 Hello Andrea Rossi, I would like to point your curiosity at the [forgotten] Nitinol engine ( memory metal / Nickel-titanium ) It could be interesting as such engines run amazingly efficient even on small heat gradients. The original idea [back in the days] was to use waste heat as a source. The video here gives some historic perspective. http://blog.go-here.nl/8652 Hope this helps! Good luck!
Re: [Vo]:Nitinol heat engine
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.
Re: [Vo]:Nitinol heat engine
Dale Basgall suggests that gadolinium expands when exposed to a magnetic field and contacts when the field is removed. In our past discussions, he was thinking you could create a rapidly oscillating pressure in the cell using some gadolinium and EM pulses. We have also long thought nitinol may have some application to LENR because of the mechanical shifts in the metal lattice when heated and cooled (and associated effects on hydrogen loaded into the lattice). An interesting application of gadolinium based on its magnetocaloric properties (refrigeration). http://www.eurekalert.org/features/doe/2001-11/dl-mrs062802.php On Wed, Mar 11, 2015 at 8:21 PM, Axil Axil janap...@gmail.com wrote: A shape memory alloy can operate at very high temperatures in excess of that produced by the dog bone.
