天哪!懸浮超導體和臭名昭著的懸浮滑板

特拉維夫大學的研究人員釋出了一個關於超導物理學的精彩 YouTube 影片,特別是關於被稱為“量子俘獲”和“量子懸浮”的現象。

在影片中,我們看到一個陶瓷圓盤懸浮在磁性表面之上。陶瓷圓盤被冷卻到零下 185 攝氏度以下,在那裡它變成超導體,透過平衡磁場中的擾動,圓盤的方向可以鎖定在兩個軸上的位置,使其能夠以一定角度在表面上滑行。

不難想象,使用這樣的技術來開發新一代高速列車;用於傳統軸承或襯套可能不足以勝任的製造應用;在光伏系統中跟蹤太陽;或作為化工廠中的一系列感測器。當然,將陶瓷冷卻到零下 185 攝氏度並非沒有成本,並且需要能量。

對於我們這些在 80 年代長大的人來說,擁有交通運輸領域的終極裝置的夢想——馬蒂·麥克弗萊的懸浮滑板或盧克·天行者的陸地飛車——可能離現實更近了一步。或者至少是更高效的製造工藝。
