Carbon nanotubes: The weird world of 'remote Joule heating'

Minimizing Joule heating remains an important goal in the design of electronic devices^1, 2. The prevailing model of Joule heating relies on a simple semiclassical picture in which electrons collide with the atoms of a conductor, generating heat locally and only in regions of non-zero current density, and this model has been supported by most experiments. Recently, however, it has been predicted that electric currents in graphene and carbon nanotubes can couple to the vibrational modes of a neighbouring material^3, 4, heating it remotely⁵. Here, we use in situ electron thermal microscopy to detect the remote Joule heating of a silicon nitride substrate by a single multiwalled carbon nanotube. At least 84%of the electrical power supplied to the nanotube is dissipated directly into the substrate, rather than in the nanotube itself. Although it has different physical origins, this phenomenon is reminiscent of induction heating or microwave dielectric heating. Such an ability to dissipate waste energy remotely could lead to improved thermal management in electronic devices⁶."

These experiments seem extremely important in constructing AI singularity timelines, what does lesswrong think?

What is the impact on life extension research?

I don't see a line of inference free of holes, but one can imagine the sort of uses a scifi author would come up with.

Thanks for explanation. Now my model is that you consider carbon nanotubes very important technology for increasing computational power (more than many other hardware-related technologies), so they are also a very important component in calculating Singularity timeline. Makes sense, though I lack the knowledge necessary to discuss it.

I posted the most relevant abstract. If they spent some fairly large time writing that, why should I assume I can do better?

Because they were writing for a different audience -- for people who already know a lot of context.

Now it's your choice whether you want to discuss with an average LessWronger, in which case you should provide more content, or you want to discuss only with people who are experts in some area, which is completely legitimate, but perhaps you should state it more explicitly.

It is indeed kind of mean that I ask how this piece fits into everyone's puzzle without disclosing my puzzle, but I do worry about security and that sort of thing and this was a good experiment on how people would respond

That's good. I was hoping you will not get the impression that we are somehow biased against discussing singularity or carbon. :D

I think it tends to be most useful to do things that support multiple different plans, so I had a lot of motives for putting this up here. I don't have a lot of time, so that's how I try to roll anyway...

Here is what my motivations were :

In general play with the site - I did a little bit of work on it in the summer of 2010 and I was talking about making a contribution again, so I wanted to play with the interface and understand the code better.
I enjoyed my time at singinst, but was one of the rare people that had never read lesswrong when I arrived
