雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。710Please respect copyright.ＰＥＮＡＮＡXGnDbrpSEq
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。710Please respect copyright.ＰＥＮＡＮＡgs9I6hClr2

（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。710Please respect copyright.ＰＥＮＡＮＡzeO35OzIMp
710Please respect copyright.ＰＥＮＡＮＡFN9tJ4kfNn
710Please respect copyright.ＰＥＮＡＮＡJL8vhJSQpY
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。710Please respect copyright.ＰＥＮＡＮＡ7J2lplEno9
710Please respect copyright.ＰＥＮＡＮＡiDz4JJ5nMZ
（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。710Please respect copyright.ＰＥＮＡＮＡAepPtW9b9T

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。710Please respect copyright.ＰＥＮＡＮＡulrBqgcVW8
710Please respect copyright.ＰＥＮＡＮＡw3NNuABR82
710Please respect copyright.ＰＥＮＡＮＡHZYxGQ9P7t
選用Fe(CN)6 –4的原因基於其兩種特質。710Please respect copyright.ＰＥＮＡＮＡPGK5YRA865
710Please respect copyright.ＰＥＮＡＮＡX6wOebIPn4
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。710Please respect copyright.ＰＥＮＡＮＡ1rpmezecpT
710Please respect copyright.ＰＥＮＡＮＡGSneR6bDXs
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。710Please respect copyright.ＰＥＮＡＮＡm1GvgrQWWd
710Please respect copyright.ＰＥＮＡＮＡ1K7eUMw5Z0
（圖4）以下就是利用熱力發電的精髓要點。710Please respect copyright.ＰＥＮＡＮＡgaj457UQFo
710Please respect copyright.ＰＥＮＡＮＡQuofUlJMnc
710Please respect copyright.ＰＥＮＡＮＡGjlgEAXE2I
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。710Please respect copyright.ＰＥＮＡＮＡ6xxCPsSyGP
710Please respect copyright.ＰＥＮＡＮＡ2vQopkIhqP
2.電子在閉合電路走動，產生電流，讓燈泡發亮。710Please respect copyright.ＰＥＮＡＮＡZl0zuc0qSi
710Please respect copyright.ＰＥＮＡＮＡiuvWLZh8F7
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。710Please respect copyright.ＰＥＮＡＮＡyBDekZ40bT
710Please respect copyright.ＰＥＮＡＮＡMHLZfJ0D49
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。710Please respect copyright.ＰＥＮＡＮＡWehfsmSvKX
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。710Please respect copyright.ＰＥＮＡＮＡyIzEI17GeJ
710Please respect copyright.ＰＥＮＡＮＡ2oFeGCoUAH
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。710Please respect copyright.ＰＥＮＡＮＡuN5WiRkfRm
710Please respect copyright.ＰＥＮＡＮＡIMiBZ29Mhm
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。710Please respect copyright.ＰＥＮＡＮＡTo2Lj1CeAj
710Please respect copyright.ＰＥＮＡＮＡis2vavRvpq
（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。710Please respect copyright.ＰＥＮＡＮＡehQ7LwsGPl
710Please respect copyright.ＰＥＮＡＮＡOqb6IE5Abs
710Please respect copyright.ＰＥＮＡＮＡs5fmwGhSb4
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。710Please respect copyright.ＰＥＮＡＮＡy6Vthq3xQH
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。710Please respect copyright.ＰＥＮＡＮＡ1YV1OSTX2k
