 Hi Gunther:

 Would that  "liquid helium"  possible  be liquid nitrogen?

liquid nitrogen - boils at 77 K
liquid helium -  boils at 4 K

superconductivity occurs near 0 K

 Hi DednDave:

 So helium is colder than nitrogen.

probably the only place you'll see it - lol
can't imagine what would happen to a human body at that temp   :icon_eek:

 Hi DednDave:

 I assume your body would freeze and break in to pieces.
 A bit like dry ice on steel.

More or less, but I seem to recall something about new materials that support superconductivity well above absolute zero, but there was a problem fabricating functional wires from the materials.
Well Microsoft, here’s another nice mess you’ve gotten us into.

Hi,

   It looks as if they are getting to the point that superconductivity
using a coolant other than liquid helium may soon be possible.

High-temperature superconductivity

I seen two teenage boys showed a special ceramic could use liquid nitrogen as coolant in a school in halmstad sweden
It was actually come up from someone researcher who won nobel price

Hi Steve,

I hope so, because we'll have a large problem with helium in the future.

Get your facts first, and then you can distort them.

Gunther, why it will be so? (sorry for incompitent question)

the universe is almost out of helium
they used it all up at CERN   :badgrin:

Just scoop couple buckets of it up from the closest star, Dave :biggrin:

The US sources of Helium, and I think this represents a lot of the world sources, are running out and the rate of new (terrestrial  :biggrin:) production is extremely slow.
