I feel like this massive caveat was buried half way through the article. This is why I dislike university press. I mean, the wizardry is impressive, but it isn't gonna revolutionize anything anytime soon if it requires a vacuum and liquid Krypton-ish temperatures.
- hanniabu 2y agoCould be useful in space where those are the default conditions
- chongli 2y agoSpace is a fantastic insulator. Space suits for astronauts have to be cooled, not heated.
- syntaxing 2y agoI think it’s more appropriate to say conduction and convection doesn’t work well. When you have a suit, it’s meant to block radiation and that’s the mode of heat transfer in space. If space was a fantastic insulator, the suit itself would eventually overheat since you have to remove the heat somehow (they boil off water in vacuum similar to sweat).
- Tade0 2y agoIt's not that bad - 118K is slightly above the boiling point of LNG(~112K), so achievable at scale.
- mjfl 2y agoIt’s basic research
- pbhjpbhj 2y ago>but it isn't gonna revolutionize anything anytime soon Reminds me of CCD. Back in the day CCD only worked effectively at liquid nitrogen temperatures; a couple of decades of development and you could have one in a pocket camera. Maybe that's what you meant.
- okwhateverdude 2y agoIndeed, that is what I meant. This is a neat result, just not practical yet.
- Ma8ee 2y agoWe are on the other hand still waiting for the room temperature super conductor and the fusion reactors. I’d say that most interesting breakthroughs never reach the stage where they are useful.
- mensetmanusman 2y agoSo it works at room temperature in low earth orbit.
- floxy 2y agoBecause of solar radiation, you have to take special measures with heat shields, etc, to achieve low temperatures in low earth orbit. https://www.grc.nasa.gov/WWW/k-12/Numbers/Math/Mathematical_Thinking/estimating_the_temperature.htm https://www.grc.nasa.gov/WWW/k-12/Numbers/Math/Mathematical_...
- kolanos 2y agoCould it have a practical use in space? Which is both already a vacuum and close to absolute zero temperature wise?
- idunnoman1222 2y agoA practical application of storing data in space that could just easily be beamed to earth to be stored?
- r3trohack3r 2y agoFrom everything I’m seeing so far, all protocols for space are stateful to deal with the incredibly high latency. I can see a future where the space between earth and mars is a constellation of massive caching servers.
- worthless-trash 2y agoPlease, we can only get so excited.
- m463 2y agoyou could have rotating disks that can encode data as they turn towards the sun. Or the sun's light could drive the rotation using magnetic force.

- megablast 2y agoExactly. I can’t believe they published something if we can’t buy it and use it right now.
- 52-6F-62 2y agoThat’s good. Ideally we won’t have a scattering of profit seeking engineering firms casting magnetic fields everywhere when we have the most cursory scientific understanding of high spin metals in the brain. If anything, we might reassess our current usage… https://pmc.ncbi.nlm.nih.gov/articles/PMC8189590/ https://pmc.ncbi.nlm.nih.gov/articles/PMC8189590/ https://web.stanford.edu/group/solomon/research.html https://web.stanford.edu/group/solomon/research.html https://www.sciencedirect.com/science/article/pii/S2666522023000011 https://www.sciencedirect.com/science/article/pii/S266652202...
