back when this was done [5KW nitinol engine] it was very pricey and no one was sharing the Why's or How Too's
a lot has changed price wise ,and hopefully we can make all manner of NiTinol shapes and sizes too ?

a nitinol bhaskara wheel
as a test bed
but with more mass in motion [no rubber bands] just off the shelf nitinol wire to start.

all comments welcomed and appreciated

It is much more efficient to use the mechanical energy of
the Nitinol directly as the driving force.
Rather than using it indirectly to utilize gravity.


Linear actuators could rotate a crankshaft
For example


This stuff needs only very small temperature differences
Which puts it in its' own category of heat engine.
And the extreme nature of the output defines it in a
category separate from the Carnot cycle.


I think the only thing holding us back was the price.
If that's gone down, we can design a limitless array of machinery.
