Could Mercury be used as robotic blood?
« on: 17/01/2009 17:58:18 »
I have a fastination with mercury and its ability to flow at room temperature but think its properties must be underused. So can Mercury be robotic blood? Any other theoretical uses would be most appreciated.

Mercury has one huge downside, it's poisonous. I'd say that's the main reason why it's not used i.e. in thermometers.

But in a sealed unit, surely it could have some uses.

I don't know much about robots, but I don't think it could be used for something in there. Or you intended specifically to find a use of Hg as a veichle of chemicals or of energy or as coolant?

Duh ... they're robots - so it won't matter.  [^]

Mercury is a metal, so it could be used to conduct a current in a robot body rather than a wire.

I don't think they'll get past airport security! But they'll also be very heavy, the robots that is. They would have to be very well insulated because any leaks could mean trouble.

The European Union has banned exports of mercury from 2011, in order to cut emissions of the toxic metal into the environment. Meanwhile, the US is expected to pass legislation that would see its mercury exports banned from 2013.

Where are they going to obtain mercury for so-called eco-friendly fluorescent lightbulbs ?

Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal.

Under EU legislation adopted on September 25, from March 2011 mercury waste from industrial processes - such as the manufacture of chlorine and the production of vinyl chloride, the monomer of PVC - will be stored in steel containers in underground salt mines.


Quote
The EU chlor-alkali industry is currently phasing out its use of mercury electrodes to manufacture chlorine and caustic soda, and expects membrane technology to have replaced them by 2020.

The CFLs will probably be replaced by something else, I think...

Why would a robot need blood?
Mercury isn't a very good conductor of electricity so I wouldn't use it for wires unless there were some really good reason.
On the other hand it might be useful for cooling things.
Since mercury dissolves quite a lot of other metals, I think that it could be thought of as poisonous from the robot's point of view.
Please disregard all previous signatures.

If you mean "robot's blood" for electronic impulses it won't really work that good. because its conductivity measure in Siemens is: 10.163s/cm compare to cooper that is 595.8s/cm and silver's 630.5 s/cm.
the power dissipated by mercury will be as much as 58 times greater than cooper and 62 times greater than silver.
for any electronic circuit we want as much efficiency as we can.  [;)]

Not in large quantities. My grand mother is a nurse, one day I liked the way mercury looked so i broke the thermometer and start playing with the it. [xx(]
what I remember is that it did not blend back together. Why is that?

can you explain how to calculate mercury's tension ,and compare it to water's tension.

Don't worry, it didn't do anything to you (I hope you didn't swallow it, right?  [:)]). But that amount of mercury could be dangerous if you let it in the pavement (or in any other place without being closed in a container) for a long time without opening the windows: its vapour tension generates dangerous concentrations of the vapour in air, with time.

Because the drops' surfaces became dirty and so the drops couldn't touch effectively.

is that they are sharing n/2 bonds, just like semiconductors. For example a tetravalent (silicon) is bond with a boron (trivalent) to make a extrinsic molecule.

I'm afraid at one stage people weren't quite so aware of the problems Mercury presents. I would say about 30 years ago it was common for children to push the balls of Mercury around in a tray as part of their science lesson.
One of my lecturers was ill for a month after topping up a manometer with Mercury. He was riding home on his motorbike and suddenly lost his balance. He couldn't stand up and had to crawl along the footpath and into a pay phone. He somehow managed to ring 999 for help. He had not been told that he should take precautions with Mercury at all.

Do you mean that he only opened the manometer? How much time was it left opened?
Some years ago I heated with a flame some grams of Hg with some grams of tin in a test tube to speed up the formation of amalgam (no hood!), for about 1 minute; in those conditions the Hg vapours concentration in air shouldn't have been so low. I knew it was dangerous but I only took the test tube with a hand at ~ 0.5 metres from me. I didn't experience anything strange.
