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.

My reaction: You have posted a link to some invention, without explaining why it is related to singularity more than any other random technical invention. Sure, there are three hyperlinks where I can get more information, but I would like to get some explanation from the article itself. Or maybe you just use "how does X advance singularity timelines?" as a synonym for "X is cool"; I don't know, and you didn't help me avoid this suspicion.

What would I like to find in articles like this? A short explanation of context (for people who know nothing about carbon nanotubes, which is not a typical LW topic), and explanation of why do you think this invention is exceptional (even when compared with hundred other inventions made and published in the same year). Something like this -- the following text is completely made up, just to better illustrate what I mean:

Estimates of Singularity timeline are often based on the Moore's law. However, in recent years the progress in computer speeds has slowed down. Computers are not getting faster anymore. Their increased power is mostly gained by adding more processor cores, which is not the same as making faster cores. Also the electric power consumption increases linearly with the number of cores, so even if in 2050 we get a computer capable of simulating a human brain, it would require more power than is produced by Sun. One possible solution is to avoid an integrated-circuit approach and build the computer directly, atom by atom. (Just like we got a thousandfold increase in capacity and speed by replacing vacuum tubes by integrated circuits in 1960s.) To make it possible, we need a material that is able to do -- blah blah blah -- but material with such properties is not known yet. However, recent experiments with carbon nanotubes suggest that they are similar to what we need. More details about physical properties of carbon nanotubes are here: [1], [2], [3].

Any you don't have to put "Singularity" in the name of the article. "Recent advances in carbon nanotubes research" would work fine.

Or maybe you just use "how does X advance singularity timelines?"

Very much not this. I was a visiting fellow at singinst and discussed timelines with many people. I still feel some level of ethical obligation to provide a more complete analysis as I was actually converted to have some worry about this recursive self improvement, though I tend to worry more about IA than AI (even if just because of the IA-->AI path) I'm also poking a little bit at the LW codebase again and wanted to try to stimulate a discussion and explore the site. I was ... (read more)
