雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。711Please respect copyright.ＰＥＮＡＮＡsmDVHJqwpH
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。711Please respect copyright.ＰＥＮＡＮＡ2uo6QDlsMc

（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。711Please respect copyright.ＰＥＮＡＮＡJXFE9vgOZV
711Please respect copyright.ＰＥＮＡＮＡQrcGQTarHf
711Please respect copyright.ＰＥＮＡＮＡGUOdcomz7q
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。711Please respect copyright.ＰＥＮＡＮＡy8am5aglPm
711Please respect copyright.ＰＥＮＡＮＡi41J3epIHG
（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。711Please respect copyright.ＰＥＮＡＮＡVrsKanJ2QP

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。711Please respect copyright.ＰＥＮＡＮＡFE94qgj0f0
711Please respect copyright.ＰＥＮＡＮＡH6IIdnKQ9G
711Please respect copyright.ＰＥＮＡＮＡNg2wDN1QLX
選用Fe(CN)6 –4的原因基於其兩種特質。711Please respect copyright.ＰＥＮＡＮＡZ7xVgnBmnx
711Please respect copyright.ＰＥＮＡＮＡhKKnukMCKA
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。711Please respect copyright.ＰＥＮＡＮＡuVIHCwuHpe
711Please respect copyright.ＰＥＮＡＮＡbigPVZWFld
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。711Please respect copyright.ＰＥＮＡＮＡaTNbyV8uG5
711Please respect copyright.ＰＥＮＡＮＡSPxQ5jfLfr
（圖4）以下就是利用熱力發電的精髓要點。711Please respect copyright.ＰＥＮＡＮＡwaU3axkisc
711Please respect copyright.ＰＥＮＡＮＡpOpgKAIwSq
711Please respect copyright.ＰＥＮＡＮＡsPq3e9Qvs0
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。711Please respect copyright.ＰＥＮＡＮＡ8N3mZwpj0H
711Please respect copyright.ＰＥＮＡＮＡlhNCHfKRNC
2.電子在閉合電路走動，產生電流，讓燈泡發亮。711Please respect copyright.ＰＥＮＡＮＡ4bIH9vCxTJ
711Please respect copyright.ＰＥＮＡＮＡqE44x7gQPs
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。711Please respect copyright.ＰＥＮＡＮＡqX2JEUaevt
711Please respect copyright.ＰＥＮＡＮＡyQ6kfHzRFg
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。711Please respect copyright.ＰＥＮＡＮＡ6TapYZLfi3
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。711Please respect copyright.ＰＥＮＡＮＡVxsUiHG4oO
711Please respect copyright.ＰＥＮＡＮＡjWwxMSvdhG
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。711Please respect copyright.ＰＥＮＡＮＡenRqItMdnn
711Please respect copyright.ＰＥＮＡＮＡlZ05xROBii
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。711Please respect copyright.ＰＥＮＡＮＡYZM2QPkUjO
711Please respect copyright.ＰＥＮＡＮＡxxJHjT9P7H
（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。711Please respect copyright.ＰＥＮＡＮＡzD8bf3PwCO
711Please respect copyright.ＰＥＮＡＮＡDz6u2wXLgY
711Please respect copyright.ＰＥＮＡＮＡBZqRRf7ujP
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。711Please respect copyright.ＰＥＮＡＮＡ0vaozUOnOY
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。711Please respect copyright.ＰＥＮＡＮＡi2sCNoSOoK
