Air Temp Nitinol

[Mark69]

Gadget, which engine are you going to build?  What I would like is one I could put in the basement/ attic and drive a generator.  This way I could sell back electricity to the electric company.  I would also like one to run an a/c and heater.  Heck, if they work great, maybe even one to put in a garage.

Nitinol Motors have been reported to be way more efficiant and have more torque than a Sterling heat engine . Now with the release of Air temp Nitinol there should be lots of people getting onboard for large Engines to connect to Electrical generators that run simple on our planet that has perpetual sun and air . And we all know that somthing as simple as a  joule thief can light many many leds for a fraction of the input compared to running the leds with normal current and at the very least my failed attempt proved that you can harness very high amperages with a simple Joule thief charging a massive Ultral capacitor to full charge from just a 1.2 volt battery . Generator design has been greatly inhanced over the last few years as show by tak22's link . My plan is to make single wire loops like the old thermobile toy except multipled . one problem is SLIP on the pully.. i thing with the right pully surface it will stick better . One has solved this with single Nitinol wire by making his own Nitinol Chain and using sprockets instead of a smooth surface pully My Hopes are to spur intrest and others make their own versions of Nitinol Engines.this stuff is cheap enuff now that anyone can experiment with it . You might even  have a piece of nitinol .back in the 80's old motorola flip phones had the Nitinol memory wire antenna's.other old cellphones with pull up antennas were tended to be made of memory metal covered in a poly jacket.Also if your wife or girlfriend has an old playtex miricle underwire bra there is memory wire there also
So Guys let's start ripping those bras Apart :}

I checked out the link, which has more links to a site called grand-illusions.com, where you can buy some nitinol.  They have a nitinol heat engine toy, which you also can buy.  Is this the design you will be trying to scale up?  I could see that being possible.  At the top, have a generator along with the fan.
