雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。581Please respect copyright.ＰＥＮＡＮＡB2mpD1DuVW
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。581Please respect copyright.ＰＥＮＡＮＡXQuenefDJe

（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。581Please respect copyright.ＰＥＮＡＮＡd4kWtCUwnl
581Please respect copyright.ＰＥＮＡＮＡzk77IHGKsn
581Please respect copyright.ＰＥＮＡＮＡ4YneabAj6M
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。581Please respect copyright.ＰＥＮＡＮＡB8dL3o9b90
581Please respect copyright.ＰＥＮＡＮＡABlNXvtXX4
（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。581Please respect copyright.ＰＥＮＡＮＡPjPkVsGY98

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。581Please respect copyright.ＰＥＮＡＮＡi7rknW21fy
581Please respect copyright.ＰＥＮＡＮＡr1M15s84jx
581Please respect copyright.ＰＥＮＡＮＡqab4u8urQc
選用Fe(CN)6 –4的原因基於其兩種特質。581Please respect copyright.ＰＥＮＡＮＡ0QOfcqsKCs
581Please respect copyright.ＰＥＮＡＮＡByfWzJyC8n
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。581Please respect copyright.ＰＥＮＡＮＡBTK6xoMGdY
581Please respect copyright.ＰＥＮＡＮＡpUQMkLqA3m
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。581Please respect copyright.ＰＥＮＡＮＡhD5Vkuwo6k
581Please respect copyright.ＰＥＮＡＮＡyz8lF2BNh8
（圖4）以下就是利用熱力發電的精髓要點。581Please respect copyright.ＰＥＮＡＮＡDz6HYDFHUr
581Please respect copyright.ＰＥＮＡＮＡE1ED7AxiED
581Please respect copyright.ＰＥＮＡＮＡM9elNxWpyO
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。581Please respect copyright.ＰＥＮＡＮＡaOi2KmFbiH
581Please respect copyright.ＰＥＮＡＮＡtk4xJ7r9aJ
2.電子在閉合電路走動，產生電流，讓燈泡發亮。581Please respect copyright.ＰＥＮＡＮＡPzEBtYPFGe
581Please respect copyright.ＰＥＮＡＮＡO4wv5ZnoLp
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。581Please respect copyright.ＰＥＮＡＮＡCm58mPRHEs
581Please respect copyright.ＰＥＮＡＮＡcC2B4tQfwG
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。581Please respect copyright.ＰＥＮＡＮＡRP6fMupfAL
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。581Please respect copyright.ＰＥＮＡＮＡ2aft6aZZKJ
581Please respect copyright.ＰＥＮＡＮＡvBQeIyaLxw
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。581Please respect copyright.ＰＥＮＡＮＡLLFjsPq1oq
581Please respect copyright.ＰＥＮＡＮＡnGE8ceCd5o
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。581Please respect copyright.ＰＥＮＡＮＡ8u7fUy0y4D
581Please respect copyright.ＰＥＮＡＮＡdQ25yIiXwb
（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。581Please respect copyright.ＰＥＮＡＮＡ4JmwXliinI
581Please respect copyright.ＰＥＮＡＮＡeGxmcTZCid
581Please respect copyright.ＰＥＮＡＮＡkg3GVXm146
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。581Please respect copyright.ＰＥＮＡＮＡ8HhGLCGkYP
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。581Please respect copyright.ＰＥＮＡＮＡIlKilV5owX
