EP.48 能運作300萬年！歷久不衰的「超電流」！粉絲專頁:https://www.facebook.com/scientists543/ 高溫超導體新技術，研究出連兩年幾乎沒有衰減的「超電流」，不需持續供電，可持續產生磁場三百萬年！超導磁鐵本身沒電阻，產生不會發熱的「超電流」，電流也不會衰減，但要做出一個高溫超導體很不容易，除了讓磁場穩定，因為高溫超導體本身是陶瓷結構，做線圈跟接頭是很困難… 日本理化學研究所（RIKEN）的柳澤吉紀所主導的團隊，以RE-BCO高溫超導體做出了線圈與接頭，剛開始衰減率是每小時10億分之一，到了第二年時，每小時的變化率僅有300億分之一(不供電情況下，可運行三百萬年)！本集以高溫超導體新技術，來聊聊歷久不衰的「超電流」！＃高溫超導體＃超電流＃RIKEN -- Hosting provided by SoundOn
