 look at this picture . I want multiple wheels mounted on shafts for more energy output.the  difference will be using AIR Temp Nitinol and the heat will be the air and the cool will be the water .

 another peculiar property of Nitinol: it can be bent repeatedly without showing signs of metal fatigue. And although Nitinol gets warm at the bend point when bent, like any other metallic alloy, it becomes cool when bent
back to its original shape.This metal is sounding more and more like somthing from outer space .. This is some more reading pertaning to this metal might actually have been from some of the encounters http://bragalia.blogspot.com/2011/07/roswells-memory-metal-air-force.html

the best deal is the 40 foot roll $19.95 free shipping  .I have also ordered a 1000 foot roll of this particular wire . This is what is going to be the breakthrough in Cop > 1 . the wire has Incredible spring-back power . I made a small spring  and stretched it out and hung a vise grip on it and it lifted that heavy thing right up with some warm air. . i have uploaded a few experiments on Youtube . My Id there is 4Christonly1 .

 i annealed a piece and it reacts with air and body temperature or hot water .

Gadget, how do you connect it together to form a single loop, weld?

Mark , with a Variable temp soldering station set to about 600f-to 750f and some Tin/silver solder . You have to scrape the wire to get the solder to stick because the wire has a slight oxide on it .they recommend a special Nitinol Flux  but i have soldered some without it using some acid flux and without . 

I just can't believe the strength a small piece of this wire bent in cool water then placed near or in warm water . Its like a SNAP of the finger . you ever been thumped with a thumb and index finger flicked , thats how strong this is . It's tricky to make work because you have to anneal it first before you use it otherwise its simply a stiff piece of like piano wire you cant bend . well you can bend it but it just springs back to the original shape off the roll . you can run electric current thru it to get it to glow red while shaping it then in a split second dunk it in ice water . I do this maybe 10 times except i have used a torch lighter to get it red. then after that, make it cool and bend it then alternate to hot water . The Force actually increased 10 fold and set it to a lower transition temperature than the roll was supposed to have 125F. mine set to about 80degrees Fahrenheit and works really good in your hand or a warm room . This Nitinol has Power in it you won't believe . I am Glad the Department of Energy Declassified it.I believe this stuff is overunity in it self but don't quote me on it . the Guy that sold this also believes this to be true . WE need some who who can measure force verse temp to verify this as a calculation. This wire can lift 30 pounds almost 30 inches with a ~30 degree F change. i have done a small experiment where i made a crude coil spring 1.5 inches with a foot of this material and annealed it like above and it pulled up a pair of lock pliers with some air from a blow dryer almost instantly like 10 inches back to the spring length . the wire size is only .020"  . about the size of  the third  G string on an electric guitar. In ice water a small 1.5 inch piece bends in the glass from its own weight . wet noodle . but the instant you take it out the transformation begins to stiffen it to an unbendable Wire that just retains it's annealed shape.

Gadget, sounds excellent.   I also believe that this shouldn't be too hard to get an overunity engine from this stuff.  I was doing some thinking about the design and how you want to run multiple /pulleys strands of it.  If you run a two cog system, you could have multiple "channels" in each cog, kind of like the older pulleys on cars.  The pulley on the crankshaft has like 3 rows of belts to turn all the accessories, instead of one large belt.  Unless of course you can get wider nitinol wire.  Just an idea.

here are some of my brass pulleys i will use . I have approximately 75 other brass pulleys and flywheels on order in various sizes . I see no reason that multiple loops of Nitinol wires won't work on just one pulley so at least two per set .

Hi Gadgetmall,

Thanks for the links.

I wonder if you could get a copper pulley and aluminum pulley. Put some alternating magnets near the copper to create eddy heating and the aluminum should sink the heat away cooling the wire. Might need a starter motor to get the copper heated but with enough strands it might be able to overcome the loss in the copper. Has any studies been done on using nitinol to aid a motor? Let's say I have a small DC motor running nitinol strands to a pulley while the strands are friction heated on one side by a hard rubber or plastic surface and cooled on the other. Once heated it should start to aid the motor lowering the amp draw.

Hello Gadget,


Great project! 


Hope you don't mind me thinking along a little.


I was thinking if you take hollow axles, you could run heat/temp trough them without minimal loss.


Also to gain power, just add wires to the axel. I attach a picture.
It could be tested with some copper or aluminium pipes.



I will follow you with great interest.


Keep up the good work.

Or even better, your own Nitinol powered continues gearbox !


Power in all speeds an torques on demand from a little temp difference ;-)

Wonderful Ideas Guys . Both motor assist and hollow axle .I think the Hollow Axle i will have to try . The Brass pulleys i already have and the ones on order gave been used already with nitinol single wires . Using a hollow axle to feed water on hot and cool side sounds like a doer. just need a way to couple the water inlets while allowing the pipes to be used as an axle.

Cherryman . I Love your Drawings .Great Job.Did you use cad? I wonder is you could draw up three pairs of My pulleys mounted with Nitinolwire and the hollow tube method made from Stainless steel .I intend to put steam Engine Flywheel on the top section . I have a ton of brass gears ,flywheels , pulleys etc and with a 1000 feet of Nitinol that i know i can transform to low temp  Nitinol this could be much bigger with pulleys stacked and many loops of  NiTi .. also using a Niti pump to circulate cool water while the top portion is exposed to summer air will also be pondered .. The thing about Nitinol is is can also be electrically activated so as a back up, solar panel. .. and i can always use a panel and small pump to circulate waters .. The question is will it produce more energy that it takes to run it . If air is free and light is free and makes this run then the cost of solar would have to be put into the equations.I know after 20 some years of the Government researching this stuff they came up with most every conceivable idea but there is always something they didn't think about ..  heck i have even thought of winding a Jt with this stuff and using it as HHO electrodes..just a bit of dreaming ..

Hi Gadget,


I did gave it a quick and dirty try, pic attached


I guess you will be best of with some springs in between (as drawn) to keep a minimal tension.
Although it could work counter productive by loosing rotation due to linear reaction. That will depend on the moment the Nitinol stretches out. I guess some experimenting will make that clear.


I do have some remark, by I understand u want to re-use your brass collection ;-) using the brass pulleys i hope you will have enough temp difference. or you should put them submerged in a cooling liquid.


Second, i think with this particular design there is no need for a flywheel, although flywheels might have some more properties that could benefit, and you requested one.. So there it is.


Please keep us updated , preferably by video.. I like watching those fun experiments!




If I can assist feel free to ask.


C'man

Sweet . You are Good :) Yes i choose Brass Because the Thermobile Toy Uses it . From My Understanding it is the perfect Heat Sink for Nitinol drives. I am going to use 3 pairs of wheels so 6 total for the first Experiment .The top pair or warm/hot side will be the output shaft with flywheel. i think a heavy brass flywheel on the output shaft will help turn My Generator . I have a special Generator a  KOLLMORGEN PMI SERVO DISC MOTOR U12M4T US sells used for $1395.00 .  It has  hardly any cog and a slight rotation (finger twist)  will light the filament on a 12volt car interior  bulb. I think the VT1 Design has a few weights pulling tension so it has a little give but i like the Spring idea also.These two Generators i found at the local scrap yard for 5 buck . The other is a dynamo and works like a charm spitting out over 400 VDC for 12 in .I am sure other small generators and even magnet ,coil ,Jt designs will come after experimenting . If i can get 50 -100 rpm i will be happy . i understand some nitinol motor runs Fans at 350 rpm .

Hi Cherryman,

Great ideas and nice renders.

If you can reinforce a portion of your hot and cold water lines in the house you could reclaim some of the heating costs by running a nitinol powered generator off it.
