雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。663Please respect copyright.ＰＥＮＡＮＡjupRz2DDw5
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。663Please respect copyright.ＰＥＮＡＮＡYBfEdFx4mS

（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。663Please respect copyright.ＰＥＮＡＮＡf2SOrI5z7j
663Please respect copyright.ＰＥＮＡＮＡB3vv1OIvwW
663Please respect copyright.ＰＥＮＡＮＡ1ZsH6V2ZMI
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。663Please respect copyright.ＰＥＮＡＮＡNWhX1hw3rJ
663Please respect copyright.ＰＥＮＡＮＡW0h2qzuCGC
（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。663Please respect copyright.ＰＥＮＡＮＡ7CDdimu4rK
663Please respect copyright.ＰＥＮＡＮＡUDBIz9TL6P
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。663Please respect copyright.ＰＥＮＡＮＡqfjkZTRA8i
663Please respect copyright.ＰＥＮＡＮＡMSvfxOn4o8
663Please respect copyright.ＰＥＮＡＮＡx8ZLH30rK9
選用Fe(CN)6 –4的原因基於其兩種特質。663Please respect copyright.ＰＥＮＡＮＡVskkSdUV5V
663Please respect copyright.ＰＥＮＡＮＡdT1dA6LcCc
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。663Please respect copyright.ＰＥＮＡＮＡJj5Ad9XCNM
663Please respect copyright.ＰＥＮＡＮＡqvvnEMkS04
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。663Please respect copyright.ＰＥＮＡＮＡwGSk2hMMTB
663Please respect copyright.ＰＥＮＡＮＡovh2AssvFK
（圖4）以下就是利用熱力發電的精髓要點。663Please respect copyright.ＰＥＮＡＮＡtE2nBi1xVV
663Please respect copyright.ＰＥＮＡＮＡKttQ5QkbDw
663Please respect copyright.ＰＥＮＡＮＡrecJypOb2j
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。663Please respect copyright.ＰＥＮＡＮＡdl9o6cIvFu
663Please respect copyright.ＰＥＮＡＮＡ7n0jDTOmwt
2.電子在閉合電路走動，產生電流，讓燈泡發亮。663Please respect copyright.ＰＥＮＡＮＡ3bB457IAy4
663Please respect copyright.ＰＥＮＡＮＡGrsqhSP8ou
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。663Please respect copyright.ＰＥＮＡＮＡx97Lun64F2
663Please respect copyright.ＰＥＮＡＮＡZ0CTJrtntM
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。663Please respect copyright.ＰＥＮＡＮＡ87ST54EF1w
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。663Please respect copyright.ＰＥＮＡＮＡDyBY8HPEJv
663Please respect copyright.ＰＥＮＡＮＡyzWWku1jgb
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。663Please respect copyright.ＰＥＮＡＮＡdmgTr4OChn
663Please respect copyright.ＰＥＮＡＮＡlH9OGGzeKw
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。663Please respect copyright.ＰＥＮＡＮＡd8zlWHZ0cK
663Please respect copyright.ＰＥＮＡＮＡbZGyUIPRUD
（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。663Please respect copyright.ＰＥＮＡＮＡu9ZOfBpyzQ
663Please respect copyright.ＰＥＮＡＮＡC1P0r90cor
663Please respect copyright.ＰＥＮＡＮＡyV2WkLS3uX
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。663Please respect copyright.ＰＥＮＡＮＡIyaDy90Cbo
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。663Please respect copyright.ＰＥＮＡＮＡZDj3P6c4tw
