Deep Descent Through the Crust With Molten Iron

using a batch of molten iron to take instruments all the way to the
mantle.
Supposedly the weight of the iron would cleave right through miles and
miles of rock.
I can't remember if there were any details like the quantity of the
iron, at least hundreds of tons if not much more, or how the
instruments would be insulated from the heat and still be able to use
sonar? to get the information back to earth.

They were probably using molten iron that did not transfer its heat to the
surrounding rock, and turn into a solid long before it melted more than a
few feet of the surface. This type of molten iron can only be found inside
demented skulls, it is referred to as "pig iron".

Of what materials would the instrument package be constructed not to
uncreate the electronics through temperature and pressure? The
diamond stability field is no more than 100 miles deep. If that made
any sense at all - like canthariasis in a hippo's rectum - why not use
molten lead? As soon as you get down to where the rock is hot taffy
(the USSR's deep holes), the lead will sink like a... lead sinker. If
you want it denser still, add a few tonnes of tungsten dust.

It was a telemetric geoprobe of faith. We all know how hundreds of
tonnes of molten iron in foundry crucibles keep slipping down into the
Earth's core. That is the real world source of Global Warming.

Maybe the instruments were on the surface. Some noise should be
detectable if it's busting through all that rock.

About 5% of SN articles slip past the 3 overworked editors.

The wires would melt

Copper would float on top of the iron while melting.
The 'instrument' package must be denser than iron or it will
also float out.
So maybe we take all the real hot & heavy isotopes from spent reactor
fuel rods, plus all the excess plutonium warheads etc, stir briskly and
pour .................

How far do you think it would get before it cooled down enough to
solidify?
How fast would it move (viscosity counts!)?
How big would it have to be to make it all they way without freezing?

How much is it heated by the friction of plunging through
rock that gets hotter and hotter the deeper it goes?

The pressure is in the millions of psi which would crush anything
period.
The only way to do anything is to monitor the iron from the surface.

Liquid metal has a high heat transfer coefficient so maybe a hundred
gigawatts cooling +/- an order of magnitude. A 100,000 ton batch
would cool 1000 F in less than an hour +/- an order of magnitude.
They might beat the bore holes but the iron in the center of the earth
didn't get there by this process.

seriously, as a disposal mechanism for the "hotter" types of radioactive
waste. Basically, drill deep into a suitable stable batholith with 500mm-
scale hole diameters ; load up the holes with canisters of 'hot' waste,
keeping them cool in the process by flushing with water ; carry out
conventional cementing operations above ; repeat /ad nauseam/ , probably
as a "birdsfoot" well profile, multiply sidetracked.
After a few decades, your batholith will heat up enough to lose
structural strength, and your hot waste starts sinking, in it's immediate
containment, into the depths.
If someone managed to surreptitiously (!!) drill down towards the
waste to try to get it back, the drilling fluid used to sweep the cuttings
out would chill the cutting face of the rock, making it harder.
Interesting idea, but I don't think you'd get many buyers.
