雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。649Please respect copyright.ＰＥＮＡＮＡqv1CNMTYJs
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。649Please respect copyright.ＰＥＮＡＮＡQkmuonl6XN

（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。649Please respect copyright.ＰＥＮＡＮＡR5G5HlZwCP
649Please respect copyright.ＰＥＮＡＮＡTTqQdh1qPa
649Please respect copyright.ＰＥＮＡＮＡbrN49hIjZC
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。649Please respect copyright.ＰＥＮＡＮＡmT0UCsbtQP
649Please respect copyright.ＰＥＮＡＮＡqUEM8JUXw3
（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。649Please respect copyright.ＰＥＮＡＮＡpnWSA0LEVk

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。649Please respect copyright.ＰＥＮＡＮＡqjln0ywsdf
649Please respect copyright.ＰＥＮＡＮＡ9Qhw2r6Irn
649Please respect copyright.ＰＥＮＡＮＡFTuD8i7oR2
選用Fe(CN)6 –4的原因基於其兩種特質。649Please respect copyright.ＰＥＮＡＮＡVxsZlu0q3k
649Please respect copyright.ＰＥＮＡＮＡVfebggNpdY
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。649Please respect copyright.ＰＥＮＡＮＡ3gzSi7QmVS
649Please respect copyright.ＰＥＮＡＮＡHIBbLyLo90
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。649Please respect copyright.ＰＥＮＡＮＡtbWVc9AT2V
649Please respect copyright.ＰＥＮＡＮＡjt0syF39SP
（圖4）以下就是利用熱力發電的精髓要點。649Please respect copyright.ＰＥＮＡＮＡ9Dc42zXKSS

649Please respect copyright.ＰＥＮＡＮＡdSEuo3Fnmq
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。649Please respect copyright.ＰＥＮＡＮＡK96Uxqb0x8
649Please respect copyright.ＰＥＮＡＮＡcwDIRikgIX
2.電子在閉合電路走動，產生電流，讓燈泡發亮。649Please respect copyright.ＰＥＮＡＮＡFvWnyTu3QH
649Please respect copyright.ＰＥＮＡＮＡfkTMtCksRc
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。649Please respect copyright.ＰＥＮＡＮＡDG2E00FTjx
649Please respect copyright.ＰＥＮＡＮＡgO0YULa4IZ
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。649Please respect copyright.ＰＥＮＡＮＡsmil7VpEF6
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。649Please respect copyright.ＰＥＮＡＮＡPtavyPybFv
649Please respect copyright.ＰＥＮＡＮＡVncvG4bNme
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。649Please respect copyright.ＰＥＮＡＮＡt3oqQ0hRos
649Please respect copyright.ＰＥＮＡＮＡHqG5SXymUw
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。649Please respect copyright.ＰＥＮＡＮＡ3Ng79WZeqr
649Please respect copyright.ＰＥＮＡＮＡ3bcNBK4NNi
（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。649Please respect copyright.ＰＥＮＡＮＡCjZ3Du66hp
649Please respect copyright.ＰＥＮＡＮＡZREfliMSez
649Please respect copyright.ＰＥＮＡＮＡiiJho7i4cp
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。649Please respect copyright.ＰＥＮＡＮＡGl7Uo8Lmg3
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。649Please respect copyright.ＰＥＮＡＮＡLcJ0wqr3g4
