Air Temp Nitinol

[gadgetmall]

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.

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.
