Peter Lindemann knows well about it, it seems Free Energy | February 2012 Update
Quote : "The point is clear. Tremendous amounts of mechanical energy can be produced by the proper mechanism that allows NITINOL to be warmed and cooled just a few degrees. There is no debate anywhere within the "scientific community" that the behavior of NITINOL turns the Laws of Thermodynamics on their ear." End quote ....

Here is a supplier of Nitinol in China. If you do end up buying something from any of them, make sure you do it using an escrow service. I got ripped off once and always use one since.

Nitinol SMA Spring direct from

My business builds catamarans in China and believe me, if you do your research there are a lot of good quality products and materials being made there.

@ dambit, thanks for the advice.
I don't think I'll buy nitinol anytime soon, because I am a globetrotter, and move every few months/weeks. I don't have a fix place ... so I don't have a workshop.
I am a VIRTUAL TINKER (ahahaha) since several years, but I hope this info will be used by someone
How is life in China ?
Cheers, Jules.

[dambit]

No worries, I understand the globetrotter part. I don't live in China, I just commission factories there.

Your info has been very informative, great stuff

Dj?

Hey JT, aren't you a DJ or a music producer of sorts?
Maybe i'm just confused with someone else with a similar name?

I like this Nitinol alloy, it has actual potential, rather than make believe.

nitinol wires Body and air temp varities

I have some Nitinol wire ordered . first is a 5 foot section of .020 and has room temp activation 70degrees f . next is 5 ft 98.6f and finally 50 foot of 113degree f wire . looking to build a motor with wheels and a shaft to spin some magnets to capture the energy . the air temp nitinol will be very interesting as the cold temp has to be lower that the activation temp of 70F .. and the body temp wire should work nice outside cause it has been 115 degrees for three days now . HOT . so cooling can be plain old water while the air temp is over 99 most every day here in eastern nc .
anyone else getting some wire? Its on ebay for cheap . Also there is a video on youtube to show that you can solder this wire with available temp iron at about 600 degrees and use TIN/silver solder to make continuous loop for a few VCR wheels and make a thermobile

perfected Air transition Nitinol Annealing

If anyone is still working on this stuff as i am . I have perfected a specific Nitinol wire for transitions as low as air temp 75-98.6f both phases and a lower version 52f soft to 74f stiff . We have some very interesting motor concepts using no water just God's outside air and earths underground temperature .No water or at least no HOT water . we might use cool ground water .
we also have designs that can be retrofitted in your vents in your house that go to your attic . you could replace your bathroom vents with a nitinol air temp motor and run your light in there from variations of inside temp verse attic heat .
I have perfected the Annealing process of a certain wire you can purchase on ebay . It comes in 40 foot roll for 19.95 shipping included . I can make this wire phase change in any temperature as low as 10f-55f cold and as high as 72-160 hot and anything in between .get it here Super Elastic Nitinol Niti New Power Technology? | eBay

the other wires from grand illusion will not work nor some of the other brands as they need freeze spray or colder than 32f to bend . and high temps to recover ..

My Thread is here if intrested in some of the designs the guys came up with ..Thanks

No more Air Temp Nitinol for sale

Unfortunately there are no sellers selling the Pure grade NITI that has the capabilities of the wire to change in Air Temps. I have 1000 feet of it . The two sources on the Internet jdmedical and nitinol com both want a fortune for a 3 foot piece . I got a quote for 130 dollars for a 1 meter piece of .020 with the properties of Air Temp nitinol . Don't wast any money on Kelloggs stuff . It is junk and usless unless you get some cans of freeze spray to make it soft . He is advertising it as "AIR TEMP" and the the FACT verified by several others including myself is this wire is stiff in ALL air temps . You need greater than -0C

or about 30F to begin the Martensite stage . This requires you live in the Arctic or use freeze spray and therefor requires more energy needed to transform than any other wires we have tested. It contains more titanium and is not suited to be called magic wire .They sell it also in rods . these also require large amounts of freeze spray to bend them .

Hi fusionchip. I got some of the Kellogs 1mm 'super-heavy-duty' standard temp wire a few months ago and as far as I could determine, it performed as advertised - ie. below 30-40degC it lost its spring. Can't comment on any of the other grades of wire they sell.

It didn't matter though, I completely underestimated the problems involved in the 'annealing process'. The wire was way too heavy for heating with the measly blow torch I have, and it became apparent very quickly that the wire must be clamped very securely before applying any heat as it seems to almost come alive under the torch, kind of what it must be like when trying to barbecue a live snake. Also, like you recommended, I tried using some really crap Chinese supercaps I got almost 2 years ago to heat the wire - I actually bought $200 worth,ranging from 5F to 390F and intended selling what I didn't need on EBay, but they turned out to be real junk and as I didn't need the bad Karma, I still have them! BTW the manufacturer was HETER - avoid like the plague! Suffice to say, The annealing with caps didn't work for me...

My only advice to first-timers looking to play with nitinol is to start with light wire.

Build me a Nitinol Wheel Engine

Hey First post and i hate typing.

I want a Nitinol wheel engine like in the 1970 video on youtube.
I have no way of building one as i'm crap!

I'm not a free energy believer but i do believe in higher efficiency + scale = good thing. anyway!

I want a Nitinol wheel and will pay for it however i need the axel to extend below the level of the baths as well as above.

Can You Do It?

reply to the thread if you think you can and i'll tell you more.

[DeadCat]

Can you build me one of these??
with 2 additions

[RAMSET]

hope all is well

Ash
long time here.

I did reboot your topic and added another link where we will be building

Air Temp Nitinol

a wheel from a Swedish fellow, member Gwandau at OU.com [his friend actually ] which was said to run as a gravity wheel ,although with no real power .

would seem a very nice design for a NiTinol engine with minimal investment
and maximum potential .

teaching the next generation the whatifs ??
and maybe ...just maybe ???

all comments welcome and appreciated
respectfully
