雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。632Please respect copyright.ＰＥＮＡＮＡTlr3ZpC8D1
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。632Please respect copyright.ＰＥＮＡＮＡikPXEDIka1

（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。632Please respect copyright.ＰＥＮＡＮＡR4n3F0FH7Y
632Please respect copyright.ＰＥＮＡＮＡl84U4eBAD4
632Please respect copyright.ＰＥＮＡＮＡlTXgSa2NUC
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。632Please respect copyright.ＰＥＮＡＮＡUx192NmqDR
632Please respect copyright.ＰＥＮＡＮＡC43Nq3hWzh
（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。632Please respect copyright.ＰＥＮＡＮＡlzdjPtOIsv

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。632Please respect copyright.ＰＥＮＡＮＡ6SQ7MHVIwT
632Please respect copyright.ＰＥＮＡＮＡbMHdh54FP5
632Please respect copyright.ＰＥＮＡＮＡtYf2Kd3Mlp
選用Fe(CN)6 –4的原因基於其兩種特質。632Please respect copyright.ＰＥＮＡＮＡotmASDVnZO
632Please respect copyright.ＰＥＮＡＮＡGTHnT3Ri2o
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。632Please respect copyright.ＰＥＮＡＮＡ3IDKeT7SsR
632Please respect copyright.ＰＥＮＡＮＡ6J3S2NPy6O
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。632Please respect copyright.ＰＥＮＡＮＡz2fh5f6tlr
632Please respect copyright.ＰＥＮＡＮＡjkacIA1F6P
（圖4）以下就是利用熱力發電的精髓要點。632Please respect copyright.ＰＥＮＡＮＡITVRsg7Oan
632Please respect copyright.ＰＥＮＡＮＡh4qQ1naa3w
632Please respect copyright.ＰＥＮＡＮＡVrdPyrNCPG
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。632Please respect copyright.ＰＥＮＡＮＡCG3Al8a7mb
632Please respect copyright.ＰＥＮＡＮＡ1antTvXI2l
2.電子在閉合電路走動，產生電流，讓燈泡發亮。632Please respect copyright.ＰＥＮＡＮＡ1qCpnMKdwY
632Please respect copyright.ＰＥＮＡＮＡUyUPLeas5g
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。632Please respect copyright.ＰＥＮＡＮＡDuytfmId9W
632Please respect copyright.ＰＥＮＡＮＡtdldaHL4CK
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。632Please respect copyright.ＰＥＮＡＮＡ2jHisVtx4q
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。632Please respect copyright.ＰＥＮＡＮＡiZCdupRBHh
632Please respect copyright.ＰＥＮＡＮＡmHE7WI3OAL
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。632Please respect copyright.ＰＥＮＡＮＡnhL3QG327p
632Please respect copyright.ＰＥＮＡＮＡvMXEr08umc
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。632Please respect copyright.ＰＥＮＡＮＡ6g1Vug2ZUD
632Please respect copyright.ＰＥＮＡＮＡ3ni9blfTQr
（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。632Please respect copyright.ＰＥＮＡＮＡoU9uIFPlAi
632Please respect copyright.ＰＥＮＡＮＡZf8R20HsXe
632Please respect copyright.ＰＥＮＡＮＡKhByrkVGI0
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。632Please respect copyright.ＰＥＮＡＮＡpo4vQTik1c
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。632Please respect copyright.ＰＥＮＡＮＡePMaSFZ5rR
