Nickel costs a lot and it's difficult to produce decent chemical ratios for the alloy. A big thick bar is a LOT more material and will costs way too much. A .006" thick sheet 8" by 3" costs ~$500z. Imagine a thousand sheets for a brick 8x6x3... $500,000
Shockingly poor and inaccurate reporting! Not only is the subject matter old and outdated, it (Nitinol) is very well understood and in common, everyday use. This video should be removed from the internet.
I heard of Nitinol decades ago, and these devices are exactly what I envisioned then. The big questions are:
Why haven't we seen any of this developed into machines or power generation? Who has been sitting on it?
Why are the only industries that are using Nitinol medical and dental instead of heavy industry?
With its superelasticity (not mentioned here), why aren't they making it in THICK bars and rods, which would allow for MUCH more total force? Why only thin wire?
@TravelerDiogenes This video and some of the comments made by the scientists are sort of misleading. Nitinol is NOT a source of energy. It is not the key to a perpetual motion device. Its phase transitions/mechanical hysteresis allows it to be used in energy conversion devices. The energy still has to come from somewhere, be it oil or solar or what not. No one is burying anything, I have a piece of single crystal shape memory alloy in my hand right now.
@TravelerDiogenes The term "free energy" refers to the fact that a solid state heat engine such as the ones shown here can get useful energy that would normally be wasted as heat from other processes. So, in effect, it is free because you don't have to burn any additional fuel to get more energy. It's just not (currently, anyway) economical to strap a nitinol solid state heat engine onto every heat-producing process out there.
Dieses sogenannte gedächtnismetale brauchen sehr wohl eine externe energiequelle in form von wärme.Ohne wärme nehmen sie ihre ursprüngliche form nicht an.Die dabei freigesetzte energie ist nicht größer als die energie die man reinsteckt um das wasser zu erwärmen.Das ist fakt!
Can this be coupled to a heat-pump to drive the temp differential needed - enough to drive the motor?

Das hat mit free energy nichts zu tun.
Dieses sogenannte gedächtnismetale brauchen sehr wohl eine externe energiequelle in form von wärme.Ohne wärme nehmen sie ihre ursprüngliche form nicht an.Die dabei freigesetzte energie ist nicht größer als die energie die man reinsteckt um das wasser zu erwärmen.Das ist fakt!
