Room Temperature Superconductor Found

They traded low temperature for high pressure. And even then only at a single point. So not really any closer to practical applications than before.

A superconductor is worthless if the power needed to pressurize it or supercool it is greater than the power it's supposed to be conducting.
 
I wonder if there are places in the Universe where the conditions for this superconductivity occur naturally?

I got as far as converting 200 Gigapixels to Kg/M2. It's 20394324259.558

A bit more Googling shows that neutron stars are not required. Pressures even at the surface of a neutron star are at least 12 orders of magnitude more than required!

Jupiter seems a better bet. Per Wikipedia "The temperature and pressure inside Jupiter increase steadily inward, due to the Kelvin–Helmholtz mechanism. At the pressure level of 10 bars (1 MPa), the temperature is around 340 K (67 °C; 152 °F). At the phase transition region where hydrogen—heated beyond its critical point—becomes metallic, it is calculated the temperature is 10,000 K (9,700 °C; 17,500 °F) and the pressure is 200 GPa. The temperature at the core boundary is estimated to be 36,000 K (35,700 °C; 64,300 °F) and the interior pressure is roughly 3,000–4,500 GPa
Just find a fully cooled down Jupiter and we may be on to something. :cool:

Not by any definition of shirt-sleeve environment, most commonly defined as, “ Shirt-sleeve environment" is a term used in aircraft design to describe the interior of an aircraft in which no special clothing need be worn.”

While the ISS is a shirt-sleeve environment, an EVA outside the ISS is not. Sure, you could try just wearing shirt-sleeves, but you would not enjoy it (for long).

It might be quite easy to have superconducting wires on the deep ocean floor then: cool and pressure.

Maybe cool enough but nowhere near the right pressure. " . . . pressure at the Marianas Trench to be about 1.1 × 10^8 Pa" ie 1.1 GPa. So a couples of orders of magnitude too low. :(

Turns out "room temperature" is also commonly commonly defined - to a much narrower range than "any room at any temperature is at room temperature". There are even specific ranges defined in some industries:

Ummm... wouldn't that be 0.11 GPa?
Code: 
Kilo = 10^3
Mega = 10^6
Giga = 10^9


So, even another magnitude too low.
