Air Temp Nitinol

[Mark69]

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 ;-)
