雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。599Please respect copyright.ＰＥＮＡＮＡResL1xUrfR
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。599Please respect copyright.ＰＥＮＡＮＡLcpRw22MJL

（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。599Please respect copyright.ＰＥＮＡＮＡmplXzXYSLx
599Please respect copyright.ＰＥＮＡＮＡMQjPIi6HkA
599Please respect copyright.ＰＥＮＡＮＡgcZj4IStfk
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。599Please respect copyright.ＰＥＮＡＮＡCNOIq5Vqbx
599Please respect copyright.ＰＥＮＡＮＡA2BG2ZlnVz
（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。599Please respect copyright.ＰＥＮＡＮＡTiyBvCYw6b

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。599Please respect copyright.ＰＥＮＡＮＡ6Q2Mnn4aSs
599Please respect copyright.ＰＥＮＡＮＡyWujW4mPhu
599Please respect copyright.ＰＥＮＡＮＡILKrBBsVJj
選用Fe(CN)6 –4的原因基於其兩種特質。599Please respect copyright.ＰＥＮＡＮＡwn7jnuCpvm
599Please respect copyright.ＰＥＮＡＮＡU0QBN0JV1M
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。599Please respect copyright.ＰＥＮＡＮＡKryNStcNAt
599Please respect copyright.ＰＥＮＡＮＡ15tw9hbhVl
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。599Please respect copyright.ＰＥＮＡＮＡNDj2rzjbCI
599Please respect copyright.ＰＥＮＡＮＡJxmG4zfTtY
（圖4）以下就是利用熱力發電的精髓要點。599Please respect copyright.ＰＥＮＡＮＡj0qsWzOTwT

599Please respect copyright.ＰＥＮＡＮＡMocFMnWnOC
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。599Please respect copyright.ＰＥＮＡＮＡHSUUzFunHd
599Please respect copyright.ＰＥＮＡＮＡAHyV982LjM
2.電子在閉合電路走動，產生電流，讓燈泡發亮。599Please respect copyright.ＰＥＮＡＮＡOXFHPitvPi
599Please respect copyright.ＰＥＮＡＮＡtjPnS0jx32
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。599Please respect copyright.ＰＥＮＡＮＡwg0DBjX6AC
599Please respect copyright.ＰＥＮＡＮＡZ4k1RBPDzy
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。599Please respect copyright.ＰＥＮＡＮＡzEzVpjBOBI
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。599Please respect copyright.ＰＥＮＡＮＡedn70477N8
599Please respect copyright.ＰＥＮＡＮＡmPsibCCSCO
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。599Please respect copyright.ＰＥＮＡＮＡ9J1fwtiSJy
599Please respect copyright.ＰＥＮＡＮＡSfTotUIYGC
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。599Please respect copyright.ＰＥＮＡＮＡFMOQT8NgnV
599Please respect copyright.ＰＥＮＡＮＡQyqB4uDAmM
（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。599Please respect copyright.ＰＥＮＡＮＡF8nz9Ffro1
599Please respect copyright.ＰＥＮＡＮＡatlhnHWiNE
599Please respect copyright.ＰＥＮＡＮＡFOoWx5Qctk
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。599Please respect copyright.ＰＥＮＡＮＡIyuwLZ4G3N
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。599Please respect copyright.ＰＥＮＡＮＡ16GmKz7bgc
