Could Mercury be used as robotic blood?

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.
I have sloshed enough mercury round in my time to wonder if what caused him problems was coming off his bike rather than mercury.
Did anyone actually meassure his mercury exposure?
(it's not difficult to measure Hg in urine)

No he really did have mercury poisoning. He fell off his motorbike because it effected his balance. He was ill for months. He was quite a character. He had no eyebrows and some facial scars from burns. He was a proper mad prof.

You look a bit stunned. Are you sure that it has nothing to do with your exposure to mercury?

50/50. the environment in conjunction with the genes made me that way. maybe I don not have a robotic blood but i know how natural selection works.

Can we get back on topic. Does anyone have any sensible uses for mercury that have not already been tried. Let's say that we could make it none toxic.
Please tell me if you think this thread is "Loony" as it has been mentioned in another thread. I was trying to write some sexy threads as suggested in the other thread. Seems my efforts are not appreciated. I can't say I'm very pleased! What do you think?

But she shoud monitor the pool temperature very carefully: if it goes down 29.76 C, the liquid solidifies, and we have a statue of Make it Lady...embedded in a solid pool   [;D]

Galium supercools very easily so the pool might not freeze until it was a fair bit colder than that.
Also I suspect that the molten metal would do a very good job of cnducting heat from the body so, even at 30C it might feel rather cold.
Since the metal; is roughly 6 times as dense a water and people are roughly as dense as water then about 5/6 of the person would be on, rather than in the liquid. If it froze them most of the person would be in the air and their body heat would keep the Ga that was on their skin molten. It would be messy (and very expensive) but not fatal.
Please disregard all previous signatures.

Yes, I didn't want to get complicated...

But if you swim in water at 30C it shouldn't be much different: new water continuously removes heat from your body; furthermore, the skin and the tissues between the hot internal blood and the cold surroundings have a limited conduction coefficient, which is what, in my hopinion, actually represent the significant parameter in the heat conduction in this case. However it's an interesting question.

About this last statement I'm not so sure, just for the high conductivity of the metal; I touched a clump of 30 g of gallium and I noticed that it didn't melt until all the metal started melting. However with greater amounts it could be as you say, I cannot decide.

Then I propose a variant: a dive in strongly supercoold gallium: as soon as she is inside...cheese please!  [;)]

I just found this:
Quote
A Dutch physicist, H.k. Onnes found the first superconductor. In 1911, Onnes realized that mercury had no resistance at 4.3 above absolute zero
Quoted from: ISBN 978-0-07-312634-0

MIL, there is still hope.  [:D]

I said before: "what is a superconducting robot going to do?" and the answer: an orchestra...

Another meaning of conduct is to lead a group of musicians or a musical performance (i.e, orchestra) by signalling the beat with a baton or hand gestures, giving cues, and offering suggestions for interpretation or expression.

At what point would the conductivity be stop? does the high surface tension give it elasticity?

because vibration causes semi-solids to tear apart. If that happen the mercury will not conduct so good, and with loose conductors overheating issues would hurt the robot.

Maybe they do not have  termoregulated structures in their dermis, and they might not have a hypothalamus. so they use the dilatation of the mercury to control their temperature. [:P].lulz [;D] [;D]
