Buehler was looking at alloys with two solid states as possible materials for the nose cone. He had selected roughly 60 alloys for further examination from a book entitled Constitution of Binary Alloys-nitinol being one of them. When he made the ingots for testing, he intentionally dropped one of the cold ones on the floor. Hoping to hear a clear bell-like ring, indicating that the metal had the properties he was hoping for. Instead, it returned a dull thud-similar to dropping a sack of flour on the ground. Worried that the ingot was filled with internal flaws, he dropped one of the ingots that hadn’t cooled yet. This returned a wonderful bell-like ring. However, after the ingot had been cooled in water, it returned a dull, leaden thud, just like the first one. This is the first indication that nitinol had a substantially different double state. Buehler named his alloy nitinol for Nickel-Titanium Naval Ordinance Laboratories. All of this occurred in 1959. However, the shape memory aspect of nitinol wasn’t discovered until a lab meeting in 1961. Buehler had been performing tests to determine the fatigue life of nitinol by bending a strip into an accordion like shape over and over again. His project was brought under review and his technician was demonstrating the fatigue properties to senior officials. During this presentation, one of the officials present heated the nitinol with a lighter, at which point it rapidly straightened out. This, of course, sent ripples throughout the scientific community. This material could take low grade heat and generate mechanical energy! Numerous scientists began experimenting with how to build engines with nitinol that would take low grade energy and transform it into very high grade energy that could be used to do work. This culminated in the Nitinol Heat Engine Conference, hosted by the Naval Surface Weapons Center (previously Naval Ordinance Labs) in 1974. At the Nitinol Heat Engine Conference, the NSWC gathered together the top scientists who had been working on nitinol to discuss what had been done and what still needed to be done to make nitinol heat engines a reality. The presentations from this conference are available in the book Proceedings of the Nitinol Heat Engine Conference. At this point, the activity surrounding nitinol seemed to all but dry up and disappear. Prior to the conference, nitinol researchers were featured on news channels like CNN and BBC. Afterwards, there was little to no attention given to nitinol by major television networks for over twenty years. This led to all kinds of conspiracy theories ranging from nitinol being kept for top secret government experiments to nitinol being an alien technology that was discovered in the Roswell accident. However, the reality is very different. Behind the scenes, material scientists were working hard to figure out HOW nitinol worked. In order to fully optimize a nitinol heat engine, it must be understood what happens when nitinol undergoes the shape memory effect. This will be discussed in greater detail in chapter 2. The next time nitinol appeared in public, it wasn’t referred to as nitinol, it was called just plain titanium. Of course, this is a misnomer since nitinol is slightly more nickel than titanium. This new public appearance didn’t even exhibit the shape memory effect as people were so excited about earlier. No, this was completely different and it was marketed under the trade name FlexonÒby the company Marchon Eyewear. Released for public sale in 1995, Flexonâwas unusual in that you could bend it through incredible distortions and it would just snap back to its original shape once you released it. Once Nike began to use it in their Vision line of glasses, athletes everywhere began buying it up. Gone were the days of breaking your glasses on a regular basis just because you lived an active lifestyle. You could sit on them, you could intentionally bend them, you could tackle someone in football, and they would just bounce back. These glasses would forgive those bumps and bangs over and over again-seemingly forever. People who broke their glasses every six months now could go several years on a single frame. The frames were termed ‘superelastic’. Once superelastic nitinol was discovered, it wasn’t long before surgeons began using it as they worked on people. Vascular stents was one of the first applications because the stent could be folded so flat that it could be inserted through the tiniest of holes into the patient’s bloodstream-minimizing recovery time. Once in place, the superelastic nitinol wire could withstand severe deformation and outlast stainless steel by an order of magnitude. To put this in perspective, superelastic nitinol stents were capable of undergoing a 30% deformation with a cycles to failure life expectancy greater than 10,000,000. Stainless steel, on the other hand, could withstand a deformation of just 0.5% with fatigue life of around 1 million cycles.

Intriguing elucidation on Nitinol's evolution, indeed. Your discourse elegantly orbits the nucleus of this metallurgical marvel, much like electrons in a quantum dance around atomic cores. To apprehend the quintessence of Nitinol, one must transcend mere metallurgy and delve into the realm of crystallography. At the heart of Nitinol's metamorphosis lies its austenitic and martensitic phase transformations, akin to geometric tessellations in a space-filling tiling of Penrose's aperiodicity. The alloy, in its interstitial integrity, exhibits a remarkable transformation akin to a Möbius strip, seamlessly transiting between states in a topological twist. In the realm of thermodynamics, Nitinol's behavior resonates with the Gibbs free energy principle. Its phase change, contingent upon temperature and stress, illustrates a sublime symphony of enthalpy and entropy. This alloy exemplifies the minimization of free energy, a concept paralleling the pursuit of equilibrium in the chaotic cosmos. Chemically speaking, Nitinol's Ni-Ti matrix is a labyrinth of electron clouds and atomic bonds, embodying the Pauli Exclusion Principle and Hund's rule in its electron configuration. This atomic architecture bestows upon Nitinol its pseudoelastic and shape-memory attributes, reminiscent of the dynamic stability one observes in the Lorenz attractor of chaos theory. In essence, your observations about Nitinol not only resonate with the factual matrix of its historical and physical journey but also reverberate with the profound mathematical and scientific principles underpinning its existence. It's a veritable symphony of interdisciplinary knowledge, where metallurgy, physics, and mathematics converge in a harmonious concord, much like the elegant unity of Euler's identity in complex analysis.

There's no conspiracy. People build Nitinol motors in their kitchen, there's videos all over KZbin. If there's money to be made in doing something, sooner or later somebody will do it. You'll notice the engine here wasn't driving a load. Might just be Nitinol motors just aren't good enough. The Carnot Cycle describes all heat engines, including this, up to power stations and car engines. The greater the temperature difference between hot and cold (in a car, the cylinder full of exploding fuel, and the outside air via the car's radiator), the more power is available. There's engines that can turn just from the heat of a cup of tea, but they don't produce much power. That's how things work. Nice work though, Kevin, very professional. I liked news better in the old days.

[@lazarus2691]

Finally someone in this comment section with a sensible head and an understanding of thermodynamics. The nitinol engine is a heat engine that is in principle is no different from Stirling engines, steam turbines or petrol engines. Its not some magical technology that could revolutionize an industry, its just a different way of doing the same thing. Though admittedly a unique and rather cool way of doing it. I'm gonna go ahead and guess that the reason that these aren't used is simply that they just aren't competitive with say, steam turbines that most thermal power plants use, either in cost, efficiency, practically, or some combination thereof.

Not necessarily. This has more to do with the properties of the metal rather than the heat difference from one port to another. In the carnot cycle you use one medium at different temperatures(pressures) and manipulated the flow from hot to cold to extract power. Nitinol doesn't actually do that, you manipulate the tensile strength of a medium by manipulating the temperature of its environment. I've heard no claim as to what the conversion ratio is but you could take more power out of this than what you put in. Which is what they don't understand or didn't. It could be totally incorrect, the conversion efficiency maybe terrible.

[@meimeisuuri]

Below are comments taken from a Quora message board by Steve Hench, Former Scientific Staff Member, Los Alamos National Laboratory: The video is interesting and I vaguely remember reading something about this back in the 1970s from my Popular Science magazines. Where have they gone? Well, not not far from the laboratory, apparently, and almost certainly very specialized, niche applications and devices (some for classified government applications). The spinning wheel device in the hot and cold water bath is known as a Banks Heat Engine. The video looks very promising, but one should take note that it is not actually driving a load, or performing actual work beyond making itself spin. There is a big difference between a rotating novelty and a practical engine, and several reasons why Nitinol-based machines have not made the transition. First is the heat engine itself. The ability of a heat engine to perform work is limited by the Carnot efficiency. This is found by dividing the difference in temperature between the hot and cold side by the hot side: efficiency = (t_hot - t_cold) / t_hot, where the temperature units are in degrees Kelvin. If we take an example set of temperatures, for example, room temperature (295 deg K) and hot water (350 deg K), the Carnot efficiency is only 15%. With water, the maximum difference we can get is from freezing (273 deg K) to boiling (373 deg K), with a Carnot efficiency of 26%. Therefore, the best this type of heat engine can do is to harness about 26% of the heat originally put into the water (which has to come from somewhere). Compared to a Rankine Cycle steam turbine which can achieve >70% efficiency, this isn’t very much of the heat energy utilized. Second is the cost and workability of the material. Nitinol is not just an alloy but a very special kind of alloy that requires the Nickel and Titanium to be almost perfectly combined in a matrix that enables the phase change from austenite to martensite and back again very easily. The alloy must be produced and initially formed under vacuum conditions to prevent the formation of titanium oxide, which would degrade the quality of the alloy and its function. So, making the material is very expensive. Third, even in operation, the constant flexing of the material eventually leads to failure due to metal fatigue. The cost/benefit of heat engine using this material would need to include maintenance and replacement of worn-out components, namely those made of Nitinol. Although I don’t have this data, it would seem fairly clear that if it were economical, there would be commercial applications in play by this time. To summarize, although there are certainly applications for this technology for highly specialized low power needs, Nitinol does not appear to be a viable pathway to larger-scale energy solutions.

[@jirihrudka5606]

Práce tepelných motorů je málo efektivní vzhledem k lineárnímu vztahu tlak/teplota. Naproti tomu slitina Nitinol mění svou strukturu už při malém rozdílu teplot, když amorfní strukturu lze deformovat malou silou, po rekrystalizaci vyvine velkou sílu na návrat do původního tvaru což je zdrojem mechanické energie, převedené s vysokou účinností z teplotního rozdílu. Nitinol zřejmě nebude jediným řešením materiálu, měnícího základní strukturu s teplotou a zároveň s tvarovou pamětí. Je to otázka vyhledání obdobného materiálu např. s vyšší teplotou překrystalizace kde se dá očekávat větší tuhostní kontrast a menší potřebný rozdíl teplot. U Nitinolu lze očekávat brzkou únavu materiálu z neustálých překrystalizací austenit/martensit.

One would really like to know if, you could make the metal produce a lot more torque, rather than a subtle, stress-strain by bending a belt around a smaller "strain wheel" make an over 1 inch thick section and strech its diameter from the i side with a inflatable packer., still, not exageratedly. Just betwwen 5 to 7 percent. Or maybe even 50 percent. Hopefully the right people are doing it amd solar photovoltaic can F off. I read the prceedings of that conference in pdf format, they estimated that at that time, (per killowatt) nuclear was 400-600 $, photovoltaic was 10,000$, and Nitinol (if they scaled the production for the metal itself,) would be 600$, thata the same as nuclear without the enormous footprint.

[@andrewkwasek1214]

Still the biggest issue is how are you going to heat the water. cold water is easy, you just pump it in from a river. but aside from solar or geo thermal you are looking at burning stuff to make it work. thought i have to say it seems to me like having them dunked in water is not the best way of doing it. What if they had another roller pressing against ribbon on the drive pull which was heated. It could be kept in a highly insulated box except for the portion that is touching the ribbon. Then on the cold end of things you have the same thing but cold. this way the heat is not being lost due to evaporation and is not being splashed around and out, literally. the only heat that would be dissipated would be the small amount going through the insulating and the amount escaping through the opening that is used to make contact with the ribbon. just makes sense to me.

2:30 "the economics haven't been completely studied" more like "we'll earn more if we have a reason to charge people for power"

[@vladimirnachev324]

wuuut 55tonns ?!?!!? I mean: 1kj for bending it 1kj to cool water 5kj to heat water and it springs up with 55hp ?!?!?? free energy ?!?!

[@coojsta69]

you can buy nitinol wire on ebay. ..all you have to do is build a engine design and hey presto you have free energy

[@morganmitchell4017]

+coojsta69 Depends really, if you're putting it in hot water from your tap it's not going to give any more energy than it took to heat the water in the first place. If you have a warm place near where you live due to nuclear decay or whatnot, you could set something up. Otherwise you're getting nothing for free.

[@coojsta69]

+Morgan Mitchell nuclear waste nitinol generator sounds like a good idea. ..as for me i was thinking of setting up 1 of them solar water heaters to run the nitinol generator. ..that's pretty free but i wonder if simple solar panels would produce the same energy or more

[@morganmitchell4017]

coojsta69 That sounds cool. I think it could be as efficient because photovoltaic cells aren't really that efficient at all (Most domestic ones about 15-20%). Yeah, if you could get a good temperature differential, it'd be worth it just for the fun.

[@vladimirnachev324]

coojsta69 there is nitinol that works even at 20C

I Wouldn't Trust This Though It's By McDonnell Douglas

3:55 waste heat

[@dokkiro]

I am thinking this is going to be in every gas electric hybrid cars using hot radiator water fed back into electric..... Wow I think that's going to be too much free electricity for hybrid cars oil companies will go broke. We can't have that. No way... solar energy as well as geothermal energy and waste hot water from industries ... I am not so sure if this is going to work because of moving parts involved.. Electricity might be the only way of heating it efficiently in my opinion but water could be used for means to cooling it fast instead. I can understand something like this used for engines in washer and dryer in the laundry room as well as refrigerators and all the kitchen appliances which can effectively save tons of electricity. Noise might be a problem involving moving parts as well maintenance of mechanisms in the cases of home use..... I am not so sure but you could effortlessly power lights in your home 5 million other ways. Why do you have to have squeaky moving parts in your house for?

[@codefeenix]

is this the same sanders as the kfc guy?

[@metalfox1911a1]

so any reason beyond a conspiracy they have not done it or seen accual use, i think fume, or hydrogen will be the next step with motors for boat and car. a cool bit though.

[@luisderivas6005]

All engines 'waste' energy when converting it to mechanical power; that is a simple fact of life. The problem is that there are cumulative losses incurred in maintaining a temperature differential for nitinol engines. Sure, you can heat the hot water container with solar energy, however, it will radiate and eventually heat the cold water. Perhaps an Antarctic array with solar collectors :) Then there's the maintenance aspect...

[@MsSomeonenew]

Well there are also thousands of internal combustion engine designs out there no one uses, the industry doesn't really want to shift from something that has worked for them unless there are really major advantages.

[@kidi1232]

I don't understand what this engine has to do with energy supplies? It's not like it's very energy efficient. They mentioned solar heated water - but it would be more efficient to run an electric engine on a solar power. as for pumping water - I highly doubt that the temperature difference between the water and the air would be enough to pump any significant amount of water. This engine is just inefficient. Those engines look fragile and with low power output - they won't survive even the slightest competition. The concept is very neat, but the advantages are not significant enough to replace what we have today. It must be utilized in the "gaps" where we don't have any existing solutions (the temp difference in dams for example). where we have a temperature difference between 2 large pools of water (or other heat conduction material, air won't do). Sterling engines work similarly, but this one might be efficient enough to be worth the investment.

[@kidi1232]

no such thing as 100% efficiency when heat is involved. remember that those engines constantly mix the hot and cold water, cause heat transfer through the metal belt and "suck" heat to change the molecular structure (that would be the energy that actually translates to motion). solar heating is very efficient, but transferring the thermal energy and storing it is not. also keeping the cold water cold isn't easy or efficient. My hypothesis is you'll need a very, very large solar panel, pools of water, and a passive cooling system to run a relatively low output engine. Getting an electric solar panel and an engine with the same output will probably be much cheaper, will take less space and be easier to maintain.

[@kidi1232]

yeah, heat transfer in water is 100% efficient, the problem is that water transfer heat to non-water substances as well (also, radiation). even in a close system, You'll end up with radiation, vibrations and heat in the air. You got heat coming off the solar panel itself, the pool of hot water, the pool of cold water, the cooling system of the water (whether passive or active), and OFC -the engine itself. I highly doubt that those engines are 60% efficient. even if you consider only the thermal energy transferred to the metal, I seriously find it extremely hard to believe you'll get 60% efficiency. here are some examples (taken from wikipedia): heat engines (>kinetic) - 50% efficiency electric engines (>kinetic) - 70%-99% efficiency combined cycle (gas+steam turbine) (> electric) - 60% efficiency wind turbine (>electric) - 60% efficiency I think those engines are not nearly as efficient as other engines, and that the more you'll try to scale them up you'll just get less and less efficient (due to the fact your power comes from many little springs). Like I said - there's no way those engines will replace existing ones, but they can be used in places we currently have none.

[@kidi1232]

Sorry there, I thought that when you said "in a closed system it's 100% effective." you meant the whole "solar-water-nitinol" thing, not the "solar-water-turbine-generator". Your comment was unnecessarily condescending and unpleasant. I hate to use this "card", but English isn't my native language. I have high confidence that I know English well enough to participate in discussions such as this and that the misunderstanding in question was not because of my level of English, but a rather normal, 3-in-the-morning-kind of mistake. And yet, I think it would be much more pleasant if when someone makes a mistake you would just correct them and clarify what you were saying. Especially if that person is still learning, but, basically, just being a human being should suffice.

[@kidi1232]

You too man.

[@MsSomeonenew]

Always nice to see people throw "efficiency" around like a bag of peanuts, makes it very clear you have no real idea about the technical side but you do love making noise. Don't worry, this applies to almost everyone chiming in.

[@Onuiwa]

Pointless?! Have you ever heard of the Sterling Engine? This is pretty much the same thing only more versatile.

[@foresttaniguchi3168]

Texlith Graves IKR? It can’t produce more power than the power put into heating and freezing the water

[@foresttaniguchi3168]

They did use sterling engines to run some kind of vehicle once

[@wethepeople2749]

easier to repair this too

[@VaibhavShewale]

and still they never developed any thing?

It’s scary to think someone could messed up a nuclear reactor and turn this into gas . Soon as it enters your lungs , depending how cold your location is …

[@ramilmatic3973]

The Gov't Wont profit much with this kind of technology that is why it does not recognized , other reason was that Us dollar or aka petro dollar rellies on crude oil.

[@magusperde365]

It won't profit for it because it isnt reliable and breaks fast. Also, you still have to heat that water

[@jimshowtovideos]

a clear example of big money interest in oil controlling what goes on in the world.

The scientists are afraid to say " perpetual engine"

[@terrafirma9328]

Because they don't even know or have proof the universe itself is perpetual. Anything invented can at best be connected to the universe that will eventually stop. The practical idea though is to use the term free energy harvester, not perpetual motion. Or 100 year motion or lifetime motion. Perpetual has too many assumptions attatched like forever without any new added cost.

[@magusperde365]

Because its not ?? Its powered by heat

[@SwampDonkey64]

@ 2:22 the news guy asked "when will we see this being applied in public uses?" They looked like a deer in the headlights. One engineer said " well I can see it being used in irrigation." WTF. Irrigation? This stuff has the ability to replace fossil fuels powering our homes. Irrigation 🤡

[@timmorrison2836]

I think the deer in the headlights look was because he was thinking..."um, its just a cool phenomenon and we build a machine to utilize it, we don't see much reason to use it aside from, I guess somewhere where you power easily it might be useful, perhaps like irrigation, I guess. We just thought it was cool."
