Breakthrough MOTOR Is Made From Artificial Muscles

A refrigerator has been developed by the team at Saarland University and the Center for Mechatronics and Automation Technology (ZeMa) It is a small, compact prototype made of nitinol wire which can transfer heat between zones and could be revolutionary cooling technology.

It’s a simple spring-swashplate heat pump. My old physics professor claimed to have invented the concept using rubber bands.

This kind of technology has probably already been tested way before, this why we use gas powered refirigiators instead to transfer the heat, than using elastic bands.
It won't work for very long before those bands or strings will snap or lose their efficiency.
Just by looking at how many parts that motor has as potential failure points, it will not develop into the mainstream.
It will stay as an experiment.

It cannot cool really, it can lower its temp but while operating a motor generates a lot of heat that would interfere with the cooling

I remember when Nitinol was first announced. There was so much excitement about what it could potentially be used for. Turns out, not much. However, I do have Nitinol stents in my chest right now.

It's the rubber band fridge 10.0 that's cool 😎.

[overunityinventor]

what's the name of that material?
is it nitinol?

A guy made a small cooling fan with rubber bands and legos to use this exact transference of heat to cool the air in the volume inside the lego box, which act as a walk in cooler levels of fridge which is decent but not crazy breakthrough or anything and it only decrease the air that then releases in a blow direction to the guy's face by 5 degrees, which is to be expected due to entropic heat transference by overtime!

I remember reading about this in the 1970's. It has taken a very long time to manifest.

Since we only have pencils and paper, testing this concept could take 10 years to develop, and 20 years to produce. See, it takes that long to add up the profits from making sure manufacture equals current tech.

[rickhale]

The statement that the wires can expand and contact many times questions it's durability. It would be nice if that problem was better explained. Why is the physical deformation necessary for it's thermal properties? I imagine it releases heat when it coils and uncoils when absorbing heat.

[NoidoDev]

Can this be made into a relatively small motor? It's not explained very well in the video.

[gioni]

Fun fact, it is being used in experiments with bionic arms and legs and in early stages robotics,

Peter Hamiltons Technik aus der Commonwealth Saga ist keine dystophie mehr💪🏼

[christophercampanella]

Aren't those alloys all made from common metals too?

[Frank-qgik]

I wonder how much energy it dumps back into the coolant before it can cool the intended target?

[woodzyfox]

do you have ANY IDEA how OLD this tech is LOL! im 40 and we played with this back in high school :P

[hartwarg]

They powering things with a dang BLT motor 😂

[interhaker]

The only material that has an endurance limit is steel.
Every other material fails eventually with cyclic loading no matter how low the load

[trancetechkid]

I guess I just lack the knowledge to know how this would be useful in any way compared to the classic AC compressor or heat pumps we have now. Maybe there’s a specific test case or something. Neat theory though.

What is nindull wire ? Can’t find any info on it…
