A Thermometer In A Nanotube

Stone Rhino writes: "Yet another marvel has been created in the quest to create minature machines: a thermometer of liquid gallium within a carbon nanotube. The New York Times has an article on this. The thermometer is 10 microns long and measures temperatures from 120-950 degrees farenheit. Of course, the part I find most impractical about it is the fact that you need a scanning electron microscope to read it."

    a better use of this (does this even have a use, other than proof-of-concept yet?) might be to, um, install one of these on nanobots, and have the liquid metal spurt from the end....somehow alerting the operator that the nanobots are about to overheat.

    that's fascinating though, i was under the impression that carbon atoms were pretty small, and a nanotube would only be about 6 atoms across...from what i recall, lithium is pretty far away from carbon on the periodic chart. how does one fit one (or more) lithium atoms inside this tiny tiny tube?
