不過而家例如ITER都係試緊用液氦冷卻嘅超導體,唔係啲用液氮就得嘅所以其實可能仲有排?

paper講的superconductors 都要用銅做其中一隻成份,唔一定會大跌

係咪即係電纜可以變成電線咁幼
2023-07-28 08:50:50
呢個講得幾簡單易明

咁多野可以J 做咩J 幼電線

呢個唔得
半導體入面
有dielectric field
距離太短鎖唔死啲電子
會breakdown個dielectric

冇heat loss都仲係未解決到呢個問題

咁又唔可以咁講,到時輸電成本應該低好多,又可以發展到好多區域

火牛 motor 都大改革
本身係因為heat loss同magnetic loss要balance先要做到咁大舊
如果r變咗0
得b field loss
唔知個發展會點

星期五了,唔通假嘅
2023-07-28 09:55:19
但係屋入面仲有好多嘢要AC
2023-07-28 09:59:20
冇咁快

又唔係乜Q複雜理論, 仲 peer review 乜春呀。
直接埋牙, 整到就堅, 整唔到就流啦

問題係啲pcb上面本身都有好多interference

不過我話縮細
主要係因為而家電腦有好多空間用左去放heatsink
就算有超導體
暫時並唔係咁多野都縮到

攞嚟做ram嘅cap解決流電問題

呢兩單都係世界大事
但連登仔:微辣收皮緊要啲

留名等睇改變世界

學術派唔睇好, by CMTC, U of Maryland, Dept of Physics

It is now time to do the unpleasant: deconstruct the non-experimental parts of the Korean room temp SC claims. This is relevant because the theoretical/background SC discussions in these papers are so naïve that if it were an undergraduate project at Maryland we would give an F

如果UofM UG 寫啲咁既野出黎佢會比F

Ref. 24 is mentioned as a key theoretical reference. This work, which provides a radical hole-based SC theory contrasting with the universally accepted SC theories, is not accepted by the community at all

關鍵理論並非主流, 唔受到圍內既人所接納

....as mentioned in the BR-BCS theory" This is total nuts-- the BR is Ref. 17, a well-known work... the celebrated Brinkman-Rice theory has NOTHING whatsoever to do with SC, except in the fantasy of the third coauthor HT Kim who wrote a paper in 2017 on "high-Tc mechanism through analysis of diverging effective mass.." which was never published (because it is manifestly insane as far as we can tell) and which received only 2 outside citations!

先寫一份原創理論, 得兩次out cite

... 2307.12008 cites as Ref. 52 a recent version of BR-BCS theory published in a journal which does not reject papers Sci Rep 11 , 10329 (2021) The underlying claim is so absurd that we cannot even laugh. ...This mistake falls in the 'not even wring' category, and we will not critique it further

再引份thesis入面既原創理論...

Nothing in what we say in this tweet thread invalidates the experimental claims in these papers, which can only be verified (or not) through actual experiments in independent laboratories. We hope that such verification process is already underway in many labs

希望佢份sample係能夠完全推翻現有理論既劃時代產物啦

手腳咁慢架
撈埋拎去焗爐焗咋嘛
2023-07-28 11:14:12
佢地寫咁多做咩啊其實拎出黎試下咪知

會用到摩打/會生產摩打嘅公司?

呎吋唔大唔細, 物理上同生產上要求無咁高
用到超導體嘅話, 摩打呎吋可以細好多, 效能可以高好多
其他嘢唔駛大執都用到超導體摩打
