雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。648Please respect copyright.ＰＥＮＡＮＡcUYTqvEDec
如果將這些多餘的熱力轉化成為電力，便能夠更有效運用資源，不作浪費。648Please respect copyright.ＰＥＮＡＮＡLDHDWy9dp3

（圖2）繼續深入講解之前，我們先以非常簡單的方法概括一下發電的原理。648Please respect copyright.ＰＥＮＡＮＡCW1FukVD56
648Please respect copyright.ＰＥＮＡＮＡEkfkjMNhxr
648Please respect copyright.ＰＥＮＡＮＡ8D2JBwQsDz
只要電子在閉合電路單方向流動，就能促成電流，提供電力讓燈泡發光。648Please respect copyright.ＰＥＮＡＮＡWtEaax8Ljr
648Please respect copyright.ＰＥＮＡＮＡMOEPBbaz32
（圖3）要把熱力有效轉化為電力，我們需要一樣能夠有效傳遞電子而同時又不會傳遞熱力的物料。648Please respect copyright.ＰＥＮＡＮＡ1E9VY96J5w

有科學家最近發表文章（Ref1)，利用化學物ferricyanide ion Fe(CN)6 –4作為媒體把熱力轉化為電力。648Please respect copyright.ＰＥＮＡＮＡjPhdcfLZZf
648Please respect copyright.ＰＥＮＡＮＡh3lQpLwUFr
648Please respect copyright.ＰＥＮＡＮＡO8QhsJCvE1
選用Fe(CN)6 –4的原因基於其兩種特質。648Please respect copyright.ＰＥＮＡＮＡvcg6UnCPMD
648Please respect copyright.ＰＥＮＡＮＡJljSmk4SVj
1.它遇冷（約攝氏20度左右）的時候，再加上Guanidinium ion的輔助下便會變成固體結晶。648Please respect copyright.ＰＥＮＡＮＡnL3NIUD7MA
648Please respect copyright.ＰＥＮＡＮＡdAdw5BSgBT
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。648Please respect copyright.ＰＥＮＡＮＡJ4IFhD1qSu
648Please respect copyright.ＰＥＮＡＮＡhwHxJJsdIk
（圖4）以下就是利用熱力發電的精髓要點。648Please respect copyright.ＰＥＮＡＮＡr0qpqfUhsa

648Please respect copyright.ＰＥＮＡＮＡCOdczAOhsR
1.Fe(CN)6 –4遇上外間熱力（例如電器所散發出的熱力），因而會釋發電子並成為Fe(CN)6 –3。648Please respect copyright.ＰＥＮＡＮＡeQbQbfIjKz
648Please respect copyright.ＰＥＮＡＮＡQ9OqNQpglK
2.電子在閉合電路走動，產生電流，讓燈泡發亮。648Please respect copyright.ＰＥＮＡＮＡGWyHxErw6b
648Please respect copyright.ＰＥＮＡＮＡNbvx26TK7w
3.電子到達另一端的凍金屬棒（約攝氏20度）後，從第1點所得來的Fe(CN)6 –3便會接收電子，變回Fe(CN)6 –4。648Please respect copyright.ＰＥＮＡＮＡscxCOCOKy1
648Please respect copyright.ＰＥＮＡＮＡAsWcSRjbQY
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。648Please respect copyright.ＰＥＮＡＮＡM7Qakj0WsI
固體相對上傳熱的能力比液體較弱，因而減低了熱金屬棒把熱力傳到凍金屬棒的效率，促使凍金屬棒及熱金屬棒維持著溫差。648Please respect copyright.ＰＥＮＡＮＡPv5C0iFncC
648Please respect copyright.ＰＥＮＡＮＡoXD6zcluwb
5.在地心吸力的影響下，固體結晶會趨往金屬棒那方。而在熱力的影響下，固體結晶變回液態Fe(CN)6 –4，重回第1點不斷循環。648Please respect copyright.ＰＥＮＡＮＡy0Mi3U6dy1
648Please respect copyright.ＰＥＮＡＮＡ2YONSunfpt
綜合來說，科學家巧妙利用了Fe(CN)6 –4遇熱釋出電子的特點，以及遇冷配合Guanidinium結成固體、固體不易傳熱的特質，建造了有效傳遞電子而同時又不會有效傳遞熱力的物料。648Please respect copyright.ＰＥＮＡＮＡK5NpOCEOdq
648Please respect copyright.ＰＥＮＡＮＡO9hEOL1G2k
（圖5）科學家在文中亦嘗試利用20個圖4的模組，在兩極維持50度的溫差下，提供電力予各用途之上。648Please respect copyright.ＰＥＮＡＮＡxPdPwak32n
648Please respect copyright.ＰＥＮＡＮＡozjeygUyfo
648Please respect copyright.ＰＥＮＡＮＡtk8WTD0I7b
現在需要解決的問題，就是找出收集多餘熱力的有效方法及物料，引導熱力到模組裡頭。648Please respect copyright.ＰＥＮＡＮＡgPzILjbP1c
文章作者表示現時已積極尋找物料，相信假以時日絕有可能會在市面見到收集電器熱力發電的設備。648Please respect copyright.ＰＥＮＡＮＡiMiN1Sb1PC
