Nitinol: Free And Virtually Unlimited Fuel To Heat Your Home

[redpoint5]

I explored the use of that material as robot actuators in the 90's, but they aren't efficient and have slow cycles because the relaxation part of the cycle depends on how quickly one can waste the heat.

Does it take paint?

As for the idea of cheap durable body parts, the answer is neither nitinol nor what's currently used.

Sandy Munro predicts the future and it's kinda relevant to this use:

I believe nitinol is used in body parts, as stints for arteries.

This is the kind of Sandy content I enjoy, not him talking about Jigawatts.

I would fugeddabout paint, and the house altogether, but I prefer to remain married. If she's going to have me paint, I've got to get her to like something that won't turn the house into a gloomy cave.

That's a relevant efficiency topic, LRI (Light Reflectivity Index). It's the percent of light that a particular paint reflects rather than absorbs. Higher LRI make more efficient use of lighting since it bounces it around instead of absorbing it.

I like the way materials speak to his fingertips and tell him what they are.

5:04 it's never going to be stainless
5:06 steel stainless steel you could never
5:08 make a car that's swoopy like that out
5:10 of stainless it just doesn't happen

Never? Not even once?

Press molded stainless steel perhaps, but duckduckgo.com/?q=3D+print+stainless+steel

Is CF frame damage repairable? At any rate, part of the reason to make a frame out of steel is to absorb energy, which rigid materials simply transfer to the occupants. I suppose one would create crumple areas out of steel and attach it to CF for things that don't require a crumple zone, like the roof and doors.

Basalt fiber bends instead of shattering like carbon fiber. It's a composite so if the matrix (resin or whatever) is thermoplastic (multi-hundreds of degrees via microwave?) or disolvable it might be repairable.

Nitinol is an interesting material, especially with its shape-memory properties and potential for energy conversion. It’s been explored for heat engines and alternative energy applications, but the efficiency and scalability seem to be limiting factors. If it ever becomes viable for home heating, it could be a game-changer.
