- About 1970 there was a first important stage of developing nitinol engines. But since then, 45 years (!), nearly nothing important happened. When I started to discover this phantastic material nitinol I had the illusion, this might be an easy way and i can construct nitinol engines within several days or weeks.
But after a short time I began to understand, why this developement stopped for a long time. This material is so strange and in spite of my complexe knowledge in materials and developing things I understood nothing und no engine was running. First it was incredible boaring. But then I recognised, that I have to go again in the "first schoolclass" and this exciting material is my teacher.
Now, three years later, I feel to come into the 4th class... - and a lot of machines are already running. But I still have to learn.
I had to develope new theories and methods of handling nitinol.
So, in the next time I will offer this knowledge to interested persons and show in further films, how to handle this material.
For me it is the miracle of one of the simplest engines with the
most complex processes inside.
This engine produces energy with only 20 degrees temperature difference between the cold and warm side. And this engine produces even energy using temperature differences below zero !!
No thermoelectric device or stirling motor is working efficient
using 20 degrees temperature difference. Where this efficiency comes from and further interesting things - you can experience it in further films on youtube

Seit 1970 hat sich auf dem Gebiet von Nitinol Motoren so gut wie nichts mehr getan. Das hat seinen guten Grund. Dieses Material ist bisher in seinen Eigenschaften nicht wirklich erforsch und erkannt worden. Als ich vor drei Jahren damit anfing, mich mit Nitinol Kraftwerken zu beschäftigen, hatte ich die Illusion, in vier Wochen einen kleinen Motor zum Laufen zu bringen. Es hat zwei Jahre gedauert und ich bin fast verzweifelt. Die Erklärungen, die ich im Netz fand, waren zwar nicht ganz falsch, aber sie halfen mir nicht wirklich weiter. So ließ mich dieses faszinierende Material nicht mehr los. Heute läuft fast alles, was ich konstruiere, ob vom kleinen 5cm hohen Motor bis zum 2 Meter langen Generator. Die Leistung geht von 0,1 - 70 Watt. Und es werden immer mehr.

Used to create components for engines at large scales, or at very small scales, this is a powerful force multiplier for engine efficiency. That alone is something missing from the last 40 years and there is no excuse for it.
Well said.
20W from a 20 degree temperature difference: Better than a Stirling engine!
Hallo horst, i am so glad our nitInol wire can be used in your nitinol engine, when you need more, feel free to contact us by the way, nitinol sheet is also avalible with us. thanks Emma
+Donerven Emma Hi Emma, nice to hear you ! So you see what I did with your nitinol wires. They work quite well and i will contact you for nitinol sheets. So - my best regards from Germany Würzburg to China - Horst
+Donerven Emma I had too much spam - is working again
As I understand, you don't need to boil the water. Only a temp difference. The greater the difference, the more power. Passive solar is good in summer. A wood stove could heat water, in winter. Better yet. Keep the water cold in winter, and minimal energy to keep it from freezing. Insulate the tank as well. It doesnt even require a lot of water. Tons of options. Metallurgy is the key. Getting that material to last longer and be cost effective.
This is really fantastic. Very cool.
Dad brought little 25-cent piece sized thin discs of Nitinol, home to play with...each had a bump in the center on the convex side, and a dimple in center of concave side. Heated by rubbing with fingers, relaxed the convexity, turning it "inside out" slightly. Then, set it on cooler table top, bump-side down, and it cooled, suddenly flipping back to it's imprinted shape, causing it to have a jumping-bean effect. That was back in the 1950's or very early 1960's. He worked for Convair, which became General Dynamics...both of which had been doing some reverse engineering on certain things found at certain crash sites, in the 1940's, for instance.
Very impressed . Keep up the great work . Regards Bob ( london Uk )
Hi Merlin
I prepare the wires myself, you cannot buy them. And that is the reason why my engines are running.
Usually shape memory wires with a AF point about 50-80C are the wires in the few models you can buy.
But I use superelastic wires and preapare them in a special heat treatment. The nitinol wires have
another until now ignored feature: there is not only a programmable shape memory effect but also
a programmable strength memory effect. The AF is adjustable in a range of about 80 degrees C.
And this wires are much better for my purpose.
Horst
how do you solder them together with silver and the special flux?!
+Vladimir: - which nitinol wire do you use - because this is very important !
+Horst Wagner what about NiTi and NiTiCu
+Vladimir Nachev Co?! for cobalt
This is great tech, need to combine it with a sand battery. So heat the sand with a solar panel hooked to an electric hotwater element during the day and then allow the water underneath the engine to loop through the sand battery to maintain temperature overnight.
Excellent! Very impressive!
Well done horst. Great stuff.
How much metal would you need for a 1 kilowatt engine? It seems that these kinds of engines are not very scalable for if you would want a 1 megawatt engine you might end up needing hundreds of tons if not more while a 1 mw diesel generator will fit in a cargo truck.
Hi Horst. Good job. May I ask where you obtained your nitinol? Which alloy do you use NiTiCu,NiTi, NiTiFe? I have heard that NiTiCu is best for a heat engine, do you agree?
What diameter is your nitinol that you use for the best results? Thanks in advance.
Excelent, I liked. this have very applications.
Gute Arbeit Horst :)
Hi. Did you use the rapid cooling (or was it heating?!) technique to "program" the wire? Ps. What alloy combination did you use?
It was the heating
will you provide a video showing ' how to handle this material' ? thanks
Have you built an engine similar to the four parallel bar engine shown in the Ridgeway Banks documentary on Vimeo? Apparently he built very few and I'm trying to find someone who might have one.
Mit wieviel Ampere Strom den man durch den Draht schickt , kann man ein 1 Kg Gewicht via Nitinol Draht heben um ein paar cm ?
Ist dafür eher dünner Draht besser, weil er sich schneller erwärmt ,so dass man besser viele Drähte dazu nimmt, die alle in Serie geschaltet sind ?
Vielleicht gepulst mit nem Power Joulthief ansteuern. ...
Angaben über die Stromstärke findest Du im Netzt - etwas rumgoogeln - dünnere Drähte reagieren sehr viel schneller - es kommt also darauf an, ob es langsam gehen kann - dicke Drähte- mehr Strom -aber weniger Aufbau Technik
baut sone maschine , nitinol ist die lösung aller energie probleme, baut es!
after getting to its original shape by heating. Does after cooling will it go again to its stressed
form?
hello where you can buy nitinol springs? I need it because I would like to build such a engine
please tell me how do you make a loop or where do you buy them
Hello Mr. Wagner! I'm from the US, do you know any good websites or placed where I can purchase this material?
Hallo - I am so sorry - I prepare the material myself and we have not yet the possibility to offer it -
so keep contact and ask me again during this year - best regards - Horst
Cardi Sn: Don't believe this guy, I've bought nitinol several times on eBay, it's not to expensive. Just do Your own research & don't believe everything these people tell You. Good luck & keep in touch with me, I've made some progress, but I don't have the time to really get into it the way I want.
great video! first time watching nitinol engines
great music, can you describe the name of the musician?
Hey! Really impressed. I tried to make one like the ones you showed and I got a couple of technical problems:
when I tried to mount the loop on pulleys, and submerged half of the bottom pulley in hot water, the wire does not move. How do you get it to rotate? Is there any specific ratio of pulley sizes to be used?
Is there a way to prevent slipping?
is why the engine is fake
@@estebanvseinfarth9665 its not fake xd
How long does it take until the alloy wears down and the motor breaks and stops working?
See: Compost-Powered Water Heater provides Free heat for the Hot Tub and helps me grow organic food.
Would the water temperature be hot enough to run a nitinol engine and make some electricity? Maybe for off grid applications in the countryside?
Hi Sir
Is there is possible for replacing the wind mill turbine blade material with nitinol instead of Glass fiber reinforced plastic material..
+Vasanth Moovendan Hi - no, this does not work, because the blades would change their shape when
the temperature changes - greetings ! Horst
Well the main used of the nitinol is the blower of the hot engines and heat detector analyzer it can be used as a substitute to the mercury in the temperature analyzer
This is going to put hamsters out of a job.
Robin Stuyvesant poor hammy
Robin Stuyvesant..poor hammi
Best comment iv'e seen all day. I must be pathetic!
Realmente estupido el comentario... No da para más
Where you get so much Nitinol? I neeed to buy.
hi, what is the music in the video?
wie hast du den Draht verbunden das es ein Keilriemen wird ? Löten ,schweiße , pressen ?
How do you make the nitinol wire into a loop? Do you weld it or buy it like that?
We produce and prepare them - we try to offer them during this year -
can you tell me the ratio in the metals? and the process to make? or what is the unrestricted shape of the loop when all of it is hot at the same time? a perfect circle?
Hi David - the shape is straight if the wire is hot - but it is bent to a loop - so there is a force in direction
of the circle
Hello Horst, Perhaps you can try a solar mirror, and/or a magnifying glass on to the wire to see if it heats the wire enough during the day. Then you wouldn't need to boil water.
What if you directed the light directly onto the nitinol strip instead?
@@gregorythompson8627 thats what he said
then you could make solar panel and not need nitinol
Hi Vladimir
You can juse both, silver and normal tin solder - but important - you have to clean the Nitinol wire before -
and the rest is training, because the solder must be sucked into the gap between the wire and the
pipe. Good luck
Hi Horst. Do you have contact information so that we can contact directly? Your machine may have applications in waste energy utilization. Also would you be willing to share your special heat treatment of superelastic nitinol?
@@wagnerwerkstatt Use solar heated oil in base and fan blades attached to top for cooling. Remember yer sprocket on top for chain drive generator.
I think the area of lost energy would be, if you made an engine from this, is that the nitinol would quickly wear out and break, then you have to remelt and make more wire.
Nope. Milions of cycles. Every machine wears out, anyway.
Can this be used in a lake or river with hot water.
This ist awesome. Make a Nitinol powered Bike please :)
These nitinol engines appear to have quite a lot of potential.
puttin energy in it as heating the water... yes a lot of possible use, one can simply use a generator when we are putting heat in then leat it produce something realistic
do you believe this has potential and thank you for sharing this information
nice
enerjiyi çoğaltmak gibi
Could you post a video on how to build one of these heat engines?
Thanks for the enquiry! I hope I can do this - but it takes a lot of time to produce the video - we are just testing
and that takes all the time we have. We also try to produce the wires ourself and offer it. Is in progress - so keep on with your interest - Horst
Lötet man den Nitinol Draht am besten zusammen oder wie bekommt man da am besten eine Schleife ???
Die Drähte werden gelötet - aber das ist sehr anspruchsvoll - wir haben fast ein Jahr gebraucht, um das
Problem zufriedenstellend zu lösen
Horst Wagner Danke. Wie geht es denn am besten mit dem Löten .? kannst ja mal nen Video machen...Danke.
What happens if you connect the Nitinol engine to a heat pump so that the rotary motion is dually connected to a dynamo that gives the small ammount of electricity needed to keep the refrigerant warmed and cooled ? Surely the tremendous force with only a twenty degree or less difference needed would approach over-unity. If the right liquids or gasses are used in an enclosed system so that the Nitinol is passing through two distinct temperature zones powered by itself then it might actually keep going indefinitely ?
Argon
This must be incredibly inefficient
how do these engines stay running with no ignition setup?
Nitinol is a metal with shape memory that works when heated up, so when the wire touches the hot water it creates tension and pulls the wheel.
Can regular spring steel be used?
no Nitinol is the metal
What practical use is this? That’s what I want to know. I can’t see it in a car or airplane, for obvious reasons.
Miuch enjoy, lots of applicates
I remember when nitenol was classified. I had a hole I. My heart. They used nitenol when it was no longer classified.
The experiment seems interessant. The problem is that you must have hot water, and hot water needs energy. How can we solve this? Und I think that the wheel with greater radius should have contact with hot water to obtain more revolutions with the wheel with smaller radius. Can this be a Self-sustaining energy source?
nitinol+thermal water -free energy
The SUN
the problem of using nitinol is that the water will get too cold so for that to work you would need an nitinol engine powered boiler
NO, you use waste heat. Solar is ideal.
Lense, concentrate
unglaublich unglaublich unglaublich ...
is this real and it appears simple to make
But the hot water is not really cheap or handy.. energy is still needed. Would be cool if it would work with room temperature vs outside temperature for example. Or fresnel lens to heat it.
you actually have free energy
No you have to heat the water.
Yes with free energy systems, but this is not a free energy system, though with modifications it could be close. while you may get more energy out than you put in, the nitinol will still degrade over time, similar to free energy magnetic systems, as the magnetic Flux will never degrade, but the material causing the magnetism will, and the alignment of magnetism may degrade over time. Etc...
I can see a kit being made for bikes with quick release wheels 😁👍 for travellers
Hallo bist du noch aktiv mit den maschinen :) ich hab einen schraubendampfmotor entwickelt der auch mit kleinen temperaturen laufen kann und nur aus einem bewegten teil besteht und keinem zyklenabhängigen verschleis unterliegt wie das beim nitinol der fall ist
(Maschine: siehe bei meine neueren videos ;)
Freu mich über jede zuschrift Danke!
so what has happened? I see many engines with various means of generating energy but no one seems to be powering their home with it. Why not?
There are many reasons out there and each engine might have one or more... they can be inefficient, expensive, impractical, unreliable and even if they do good on these factors they must be better than current technologies to replace them.
Also it's FREE ENERGY... the government doesnt like the word free lol or else they would have already made them available. inefficient or not. Keep up the good work, you've come so far! I already want 1 lol
how do you heat the water?
I have a great idea what about using thin niti sheets instead of a white?!?! it should do an awesome work
Hi Vladimir
first to your question - NiTiCu is a low hysteresis alloy (5 degrees C cause the switch), NiTiFe is a heavy duty
alloy. Than there are some combinations - everything works but....: you have to prepare the alloys. If you use
the alloy you can buy, you get much less power. I treat superelastic wires with a special heat treatment.
If you want to use plates of nitinol etc. it seams to be easy, but it is`nt. The flow of heat and the forces you create are very difficult to handle. This is one of many reasons, why the developement since 1970 stopped. But play with
nitinol and make experiences and if you want you can ask me. The material is so exciting. I create new films and show step by step the features of Nitinol. The result looks easy, but there is a little universe between the trials and the result.
Best regards
Horst
There are 0.02mm niti sheets that work over 40C you can easily make a solar heating panel combined with a heatsink radiator in a water bath and run your niti engine also the remaining heat energy can be harvested with peltier plates :)
1:00 So it extracts heat from the source fairly quickly? I would like to have this to cool down my tea! 😁
Better use would be scavaging heat from combustive motors.
how much for the small 70 watt engine?
+Leo91 Hi - I just prepare a better version of this engine - it will take me 2-3 month - I can put you on my list
and inform you, when I can offer this engine - best regards - Horst
that's great thanks
Do you sell other ~100watt Nitionol engines
why it is not used to create electricity?
إخواني ممكن شرح الطريقة مع ذكر نوع المادة السائلة أرجو إيضاح هذه الفكرة
Why we don't have such power generators in real life till today..
Where to buy cheapest nitinol?
Maybe a motor like that could be used to operate a heliostat
Hey how to join nitinol wire ?
Hi - please read the text below - there I described how to join the wires - good look an best regards
Horst
kinda free energy depending on the heat needed
Perpetual motion posible?
no
@@kkknotcool porque??
@@MrSupersonico123
Because energy cannot be created or destroyed. Only transformed. In this case the heat of cool in the water is exchanged with the room temperature air to make energy.
I feel like a spring design would generate more torque than a loop
Less torque with springs. But greater distance.
By the way to increase the torque of your engine, you may use also synchronization cable. See for example this master thesis theses.lib.vt.edu/theses/available/etd-02102001-172947/unrestricted/ETD.pdf
how to make the wire?
I would like to tell it, but it is a complexe process und so it is to complicated to write it down - I tried it without
success - so I hope to produce and offer wires during this year -
Horst Wagner Sell us the wire please...thanks.
Use the Engine to power a Water Heater ?
No,the water heater powers it.
Chain cam cog leverage
Sir,Pls send me this project report
I want to share with you my idea.. Build a 250 watt nitinol engine and create electricity.. With electricity run a heat pump home aitconditioner with Cop >1 there are units with Cop --Eer 12.. Use this heatpump to heat one side of nitinol and cool the other side.. Just put the evaporator on the cold side and the condenser to the hot side.. The result is that you have created an atmospheric tempereture differentia frel engine.. Not perpetual motion energy is coming from energy earrh temperature..
Doesn't work, because it violates 2nd law of thermodynamics.
@@andreasschmitt2307 It's moving a temperature difference. The 2nd law doesn't say that's not possible. Thats like saying all heat pumps don't work.
@@jaymiew3389
Did you read the original comment? That's a very typical perpetuum mobile of the second kind.
Hallo Horst was ist aus dem Projekt geworden?
Hallo Gernot - wir sind weiter dran und haben inzwischen rausbekommen, was die Stärken und Schwächen von Nitinol sind und welches Wirkprinzip hinter der Wärme-Kraft Wandlung steckt. Leider reicht die Zeit noch nicht, um die Infos weiter zu geben - ich gehe aber heuer in Rente und dann hoffe ich dass ich einiges nachholen kann - beste Grüße und Danke für das Interesse - Horst
Why hasn't any one made a 9meter ,8mm by 50mm ?
I have an Idea, put some magnets on the wheel powered by the nitinol engine and put a loop of copper pipe in front of the magnets to heat the water needed to power the nitinol engine, then you have a free energy engine, or perpetual motion!
Hi Ernie - you always loose energy if you convert it - perpetual motion does not work - sorry...
Free energy can exist, perpetual motion cannot. Materials, even those that are aligned properly to create magnetic fields, ware down over time. So in a perfect system you will only have energy for so long, and this energy must come from an outside source, most of the time. You could argue that a windmill gives free energy, but it collapses too quickly to be used for long. Magnetic free energy systems also can speed up too quickly over time and quickly become a hazard to all around. And then the magnetism wares down too quickly for it to be of much use.
I THINK IF YOU FLATTEN THE WIRE INTO A RIBBON INCREASING ITS SURFACE AREA..YOU WOULD GET A MUCH MORE EFFICIENT REACTION.. REQUIRING LESS WIRE..
Now I know how Uri Geller did his spoon-bending magic trick.
i was thinking the same; that b+++++d!but he had several different gimmicks

sir, nitinol is the future. i hope more indian engineers realize this
Hi
liquid nitrogen,for cold, then heats own water
we have this tech and still have shity hybrid cars? oil man has more power than I realised
Why is the wheel on the top big and the bottom small,How does it affect work?
What the 1% don’t want you to see.
Why do aliens build spaceships
Nitinol: Element that companies and CEO's hate the most!
Mario Mirdita why so
43 years later still not on the market. Technology suppressed by big oil.
Suppressed? How exactly? The technology is right there if anyone wants to use it. It's just not useful, that's all :)
@@iforce2d how is it not useful?
Heat required to operate.
Steam engine.
Use solar heated oil in base and fan blades attached to top for cooling. Remember yer sprocket on top for chain drive generator.
why not make them turn turbines? generate electricity
Hi Vladimir
Look at this video - a sheet of nitinol - but I guess, this guy had a lot of problems running the machine
with efficiency and for a longer term...
ruclips.net/video/Nc-vH1ctM1g/видео.html
If you want to contact me at -wagnerwerkstatt@arcor.de - I can give you the heat treatment basic knowledge.
I will put it into youtube later.
I decided not to make patents at this point of my research - it is more important to spread the knowledge so
many interested persons can develope this engines - open source - our planet needs solutions for a more natural energy production - this may be one of them. Thermolelectric is no solution, I am specialiced in this for many years - the efficiency is not enough.
This is my thermoelectric toy I developed some years ago
