無線電力傳輸!Sony 也來參一腳

Filed under: 家電, 特色玩意


無線電力傳輸技術也說了很多年,但除了偶爾一現的接觸式充電設備之外,無線電力傳輸似乎就那麼懸在現實的邊緣上,每隔一段時間就會有個不知名的公司出來宣稱新產品「就在地平線上」,但隨後卻又音信全無。但現在看來一切都再次有了希望,因為 Sony 今天發了一個新聞稿,說明他們在無線電力傳輸方面的進展。基本上他們已經可以傳輸 60W 的電力 50 公分的距離,雖然傳輸本身大約只耗損 20%,但整個由輸電側交流電轉到無線傳輸,再到受電側換回交流電輸出,大約會耗損 40% 的電力,有點多了。

大概因為這個原因,目前 Sony 的無線輸電系統也還在試驗階段,商用化時程「未定」。好像又回到原點了啊...
