The point for me is that Nitinol engines produce very little power for their cost and size. There are far better heat engines out there.

NASA engines ?[Sterling] yes please more info/ideas ?

this Nitinol is cheaper now to play with ... we have been discussing a bit in PM's what is the best wire for My Build [Gwandau hybrid wheel]

I have a weakness for this wheel [I believe it can work] and must build it , but at the same time wish to keep the door open for
a Gwandau/ nitinol hybrid  ,[if the original wheel proves too difficult to replicate.

you should keep in mind that some of us here wish to stimulate younger minds with these builds [involve the kids]
with the whatifs on the kitchen table at night [magnets and gravity and now nitinol....
simple  open source projects...
and yes a sterling engine  does this too but a bit more involved for the kids

I personally am not interested in the traditional 'OU' ideas involving gravity, buoancy, flywheels, magnets etc, as I see them as dead ends. Involving kids in critical thinking is great (adults too!). Imho critical thinking is key to determine where efforts are most likely to pay off. Don't confuse wild ideas with critical thinking.

I have actually trained my own springs using a small oven (max 1,000degC). The cooling cycle does not have to involve ice water.

True - any ad-hoc method can produce 'some' functionality
But to truly exploit these alloys I think the methods developed
by the industry over the last 30 years may prove beneficial.
Training techniques have led to higher quality functionality
as well as increased durability.


Recently, these techniques have opened the door to multiple memories
imbedded in the same piece of metal.
