Could Mercury be used as robotic blood?

Gallium supercools very easily so the pool might not freeze until it was a fair bit colder than that.
Yes, I didn't want to get complicated...

Also I suspect that the molten metal would do a very good job of conducting heat from the body so, even at 30C it might feel rather cold.
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.

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.
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.

It would be messy (and very expensive) but not fatal.
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 have seem two new noble prize winners in one day: Esaki(with his tunnel) and Onnes(superconductivity). I like this :D

Is still useful, the only issue would be the way to keep that temperature in the robot...

Yes, fill it up with liquid helium.
But what is a superconducting robot (heehee) going to do anyway?

with some i7 processors it may be able to bake some cakes.

Yes, fill it up with liquid helium.
And for how many minutes can the robot operate before it heats up from the environment?  :)

Did anyone realize that at 4.3 K the Hg is not exactly fluid?

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.
Geddit now?

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

Why, it is a robot. Why does it need 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.

No.
With loose conductors the orchestra loses its rhythm.

I'm very pleased with this turn of events. I had not thought about superconductivity. This is why this topic was not loony! The whole point is to try and solve problems in an idea that seems unfeasible.

You mean something like: "given the fact we have found a robot with mercury as blood in an alien's spaceship, what should it be used for?" ?

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

Probably a complete waste of a post, but -

HILARIOUS.
