Interesting memory metal, Nitinol

An interesting memory metal, Nitinol

It has been around for awhile, but on OverUnity.com they posted a video that talks about it. But here is the video posted on youtube a year ago. The memory properties are amazing.

The actual YouTube posting is from 2011 but the
content is from a 1982 CNN report and discusses
events from the 1960's (first heat engine).

Considering how long ago this "discovery" was,
if it was really all that big of a deal then some
company would have made a profitable product
out of this (for energy transformation).
But, so far, I don't remember seeing it used that way.

I have never seen it used before or even played with it, but I knew is was older than I was. What I was looking at is, that it is interesting and may be a fair idea to investigate a bit about it.

The videos and metal are very interesting. The government is supressing all forms of free energy so its no surprise that we have not seen any released yet.

On coast to coast am, there have been people interviewed that talked about metal found after UFO crashes. The metal was like a thin piece of tin foil. It could be balled up in the hand, let go and it would spring back to its original shape. The Nitinol videos reminded me of those interviews. They are very similar but the UFO technology was more advanced.

May be the element 115 of the Mendeleiv table?:

they said the metal doesnt fatigue and that is not true. The problem is localized temperature. If you want a lot of cycles out of it use lots of hair fine wires.

no, an alloy of nickle and titanium

50 ton of torque i am freaking out,this is amazing,why is this not happening,the direct pull is all i need, does anyone know is it available today or could i have it yesterday ,even if a rod broke every now and then its still massive energy,im gob smacked,Thanks AB fascinating.

A quick search shows websites with Nitinol springs available at different temperature activation points:

I was curious today if Nitinol memory metal would go back to its memoty state using the heat of a small electrical current instead of heated water.

There are many links with info on this including:

Small pulses might can keep the Nitinol running while its rotation creaes energy constantly

Thanks for the links Preston

I think I will purchase some and do some experiments and see what I can think of.

Cheers Preston,i have emailed them with some specs,wait and see,i was thinking, scopes to cool the springs after they have been heated by what ever ,electricity sounds great,the faster the rotation the faster the cooling .Andy many thanks

Hi Preston,got those specs back and it seems the direct pull on a rod only creates 3 percent stretch ,there are other ways of getting the energy out ,i was thinking of a bent tube and heating it and cooling it with air again, the reaction times show potential but i feel better off with solonoids ?.Iwill keep thinking on this material though.thanks again Andy.
