Iirc (and as an extreme novice) superconductors allow for transfer of incredible amounts of energy with little to no loss, but require extreme supercooling to do so. A superconductor that doesn’t need that cooling would allow super-efficient energy transfer with very little to no cooling needed, meaning the overhead costs are reduced dramatically.

This would be a wonder technology if proven to be true, but my understanding is most of the rest of the world is highly skeptical at the moment. It’s like having your cake and eating it too.

Most scifi movie things you can think of would be on the table.

Way more efficiency, almost no heat generated. Quantum computers in your pocket. No need for fans in computers anymore, even for supercomputers. Way more efficiency at sending electricity long distances. Things like maglev trains and fusion reactors and MRI machines can use superconductors without needing to keep the temp at negative 450 F. Cheap MRIs mean accessible, inexpensive MRIs for all. The list goes on and on.

Yep. You know how hot your phone gets when charging? Or how hot a playstation gets when gaming for hours at a time?

That's due to heat-loss generated by the circuits. Superconductors would allow them to run much cooler generating essentially zero heat. Which means they can run more efficiently or faster without the need for larger heatsinks or complicated expensive cooling systems.

• Much less heat output
• Much less power usage because the components traditionally used to cool are not required (which makes it much cheaper to run)
• Lossless power transfer which is much more efficient

And faster computers
