So, then, could you use the one that has it's memory set straight at room temperature and then use a cup of cold water to create the motor effect in the same way? If so, then could you use it to power a small boat motor in a cold body of water, but with a warm ambient air temperature out of the water?

@@allylilith5605 you could keep some room-temperature water in the boat and have the wire wrapped around the wheels in a figure 8 formation, so that the narrow point of the "8" is above both bodies of water.

If it was full-sized, then you could sit in the room-temperature water to stop it from cooling down. Or you could have the tiny buckets attached to the room-temperature wheel, to catch bits of room-temperature air and force them to bubble through the water in the boat, to maybe stop it from cooling down? No, put something black over the water in the boat, so it will absorb sunlight and so stay warmer than the water the boat floats in.

general electric actually did a feasibility study on nitinol robotic actuator back in the 80s. Unfortunately its energy efficiency is extremely low about 16% base on experimental data, compare to electric motor of 95% and internal combustion energy of 30%, and even lower than pezoelectric motor of around 25%. And another issue is once you get to full scale actuator, it's very difficult to get the heat out to reset nitinol wire, so its cooling energy need for the equivalent power is much higher compare to other similar type of engine. Nitinol actuator does have pretty small packaging though, so in situation where power efficiency is not needed and it's operating in a thermal stable environment, some thing like endoscopic robot. Another setback that nitinol actuator suffers is since heat conduct through actuator material it self, so unless you have a very accurate heating and cooling control, its position precision control is much less when compare to pezoelectric motor that can have micron level precision at a high seek rate. So overtime nitinol actuator lose out to pezoelectric motor on the precision front and lose out to electric motor on energy efficiency front. Its only niche left is that it has very small packaging need, so mostly used in endoscopic robot that go through small pipe or go through human blood vessel to clear out plague.

I think this explains it, from Wikipedia: "Nitinol alloys exhibit two closely related and unique properties: the shape memory effect and superelasticity. Shape memory is the ability of nitinol to undergo deformation at one temperature, stay in its deformed shape when the external force is removed, then recover its original, undeformed shape upon heating above its "transformation temperature". Superelasticity is the ability for the metal to undergo large deformations and immediately return to its undeformed shape upon removal of the external load. Nitinol can deform 10-30 times as much as ordinary metals and return to its original shape. Whether nitinol behaves with the shape memory effect or superelasticity depends on whether it is above the transformation temperature of the specific alloy. Below the transformation temperature it exhibits the shape memory effect, and above that temperature it behaves superelastically."

I believe the way you'd do that is to heat it above the austenitic phase he mentioned in the video. This would cool down in the shape you put it in, form the rigid austenitic bonds, and then further cooling relaxes those bonds into the martensite phase which makes the metal exhibit plastic behavior.

Also with different materials. Also the bubble created appears to be plasma but has never been studied in any way.
