@andrea
That is an interesting application. Rather than the entire housing you might be able to use a hydraulic ram.

Mmm I can't figure it. May you draw a scheme? Thanks  :)

OK i Scored a broken thermobile and have had a bit of a Eureka moment . I made a Nitinol Wire loop that is sensitive to air temperature . i warmed the brass pulley to body temperature then  moved from room to room in my house which is about 75-77f depending where you are and got my Annealed air temp loop on the thermobile to spin with just the air temp change . :) Video is uploading now .Link in a few.

http://youtu.be/dAmQUZDYRe8

I do not know about any other wires other than the guy selling the 40 foot roll Nitinol Wire but i Annealed this wire just before the color changed and got My best results . the wire is light blue at this stage . it is very sensitive to air that is 75-98.6f  I call this Air temp nitinol because it only need body temp and air to react and create motion on pulleys .Now that i have a working model i am putting the finishing touches on my 6 pulley air temp Nitinol  motor and calling it the ATM (Air Temp Motor) .Remember that this wire was supposed to react to 125f if annealed with very high heat as described in Nitinol Annealing pdfs everywhere on the Internet . what they don't tell you is if you don't use high heat you get a highly reactive tuned Nitinol in the range i am working in . I already have another design in mind . It will be a Triangle with three  brass heat points and three air cooling points along the line segments  . Nitinol seems to like brass and brass transfers and holds warmth very well.
A note About the antique Vintage TherMobile . They are not manufactured since the 80's and are Very rare . I was already offered 200 dollars for mine after i fixed it and do not want to sell it . These may be worth more . They do have an expensive alternative the Heatmobile purchased here http://www.grand-illusions.com/acatalog/Heatmobile.html

Hi Gadget,

That is excellent, very little temperature change.

Another idea is the difference in temperature between the ground floor and attic. If you ever walked into the attic in the summer time you'll know the huge difference. Take a stove pipe and mount two pulleys into the ends of the pipe with your wire. Attached is a cutaway view.

Actually this is kind of what i was looking for . Now you have made it a bit simple for me:) Instead of using the  attic and the lower floor  i could use a hole in the earth for the cool section and just expose the upper portion to the Summer heat .. And in the winter maybe enclose the upper portion in glass for the hot house effect. i like it .Thank you .

Hi gadget and other experimenters.
This is a must see video and has a lot of important information

I guess Mr. Banks has been working with this material for about 40 years and he says here that it has potential.


Have any practical devices been developed yet?


I have not seen any so far.


Very sad indeed.

Hi Resin Rat
I agree with your comments, it is sad. Interesting material however looks like a lot of fun. Has a personality lol

Hi guys . It's up to us to develop a useful device . The Oil Company s certainly don't want us to have free energy .  And they sure don't want Nitinol Motors that run from air temperature Differential that is a god given  everyday  occurrence. I like the pipe setup DreamThinkBuild rendered . As simple as it seems this could be put in your ceiling bathroom exaust fan holes and easily made to spin dc Motors which Charge caps or batteries and run lights . But I am building this to go in the Ground outside . I will have to use more than three sets of Wheels . I am using a Vintage erector set (Mecanno) and having a Blast Adding Pulleys and Loops of Nitinol . Once I get enough torque on My axle and maintain some Flywheels i should have a generator model working . I don't intent to leave my valuable Toys out side permanently to rust so Eventually Plastic Framing will be the way to go and Nylon and carbon Fiber axles ..The Nitinol Won't rust or wear out as it is Nickle and titanium .. Brass will turn green but stainless or aluminum pulleys won't . Been Thinking of using a BIG heavy flywheel i have off one of those Exercise Bikes . It has a Sprocket on it and once it is spun up by hand it only need a little help to keep it going . and it will rip your fingers off . I know i made a Bedeni magnet experiment with it and you cant stop it with the sprocket. Ok been Busy on several things and keeping My Little girl happy thru summer . It's winding down and about another three weeks school starts again for her  and Me.
Ok will let you see this contraption when i get the time . It has been Extremely HOT here in the east . Every day has been 110+ and ferocious Storms Nearly Every evening ,  There is certainly enuff air heat to run this . I just have to dig a nice deep hole for the temp differential of 25 degrees . 30-40 would be The optimum power.. still waiting for My No contact Thermometers to get a ground reading . I know its cooler in ground . the water well i have is freezing cold and condensates the pipes on the well motor and storage tank.. Ok any Ideas are welcome and i hope some of you grab some of this Stuff . The 40 foot roll is It . Not the "magic" 5 foot piece . I could not get that stuff cold enuff to bend . You need at least 29 degrees F to make it soft because at 32 degrees it still retains it;s shape . The good thing about the Magic 5 foot air temp or body temp wire is it is at its Maximum Strength at 32 degrees F and above ,, This might work in the artic or some place very cold . so 29 f and below it's martensite and 33f and above its full austenite .Looks to be only about 5-7 degree difference on "Magic" Wire . I can't use it .and don't have anything that cold until winter .. But thinking ahead when winter does come I se this outdoor system in reverse . the ground will be heat and the winter air Cold .It Might just work that way too.
Thanks Markdensie for the Video . It was refreshing to see a new Old one by the Man Himself .Mr. Banks.

Been doing a little thinking, based on the original wheel with the two tubs of water.  Instead of trying to have it turn a generator, what about attaching magnets to the outside of the wheel (where the speed is the fastest) and have it passing through wire or whatever to generate electricity there?  Will it not generate more electricity that way?  Of course it could be updated to todays technology (neo magnets, etc).

That would work fine and doable . i'll order some magnet . This will be good because no cogging if we use air coils .

Right, and less moving parts means less friction and more power/speed :)
