雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。656Please respect copyright.ＰＥＮＡＮＡqVUSPcrRPY
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。656Please respect copyright.ＰＥＮＡＮＡEZzKFWS5D8

（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。656Please respect copyright.ＰＥＮＡＮＡuLIeBaD0Jb
656Please respect copyright.ＰＥＮＡＮＡ1dNkSOpiAe
656Please respect copyright.ＰＥＮＡＮＡdTldS71r9m
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。656Please respect copyright.ＰＥＮＡＮＡWYMFJl5LXx
656Please respect copyright.ＰＥＮＡＮＡ7ptH6InpM6
（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。656Please respect copyright.ＰＥＮＡＮＡ20IdIyJqju

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。656Please respect copyright.ＰＥＮＡＮＡp0yRFOI6sT
656Please respect copyright.ＰＥＮＡＮＡu8TkaVFRxK
656Please respect copyright.ＰＥＮＡＮＡCJpOVDh7g0
選用Fe(CN)6 –4的原因基於其兩種特質。656Please respect copyright.ＰＥＮＡＮＡ4PjESreTre
656Please respect copyright.ＰＥＮＡＮＡPart3EOBRT
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。656Please respect copyright.ＰＥＮＡＮＡPulZlez6bH
656Please respect copyright.ＰＥＮＡＮＡKBqL3wQCdC
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。656Please respect copyright.ＰＥＮＡＮＡFz46DW08nE
656Please respect copyright.ＰＥＮＡＮＡnQy7plnQpJ
（圖4）以下就是利用熱力發電的精髓要點。656Please respect copyright.ＰＥＮＡＮＡOuz1t9oOOn
656Please respect copyright.ＰＥＮＡＮＡuQ0Awz3NN1
656Please respect copyright.ＰＥＮＡＮＡlmZF1ZY8cE
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。656Please respect copyright.ＰＥＮＡＮＡOdm9TyX66S
656Please respect copyright.ＰＥＮＡＮＡxSgKTUBddH
2.電子在閉合電路走動，產生電流，讓燈泡發亮。656Please respect copyright.ＰＥＮＡＮＡ8a61kHjKfB
656Please respect copyright.ＰＥＮＡＮＡ0yDUiUS5FP
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。656Please respect copyright.ＰＥＮＡＮＡUI20GJ4ZH8
656Please respect copyright.ＰＥＮＡＮＡTQIcq3pTGF
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。656Please respect copyright.ＰＥＮＡＮＡHwyQONbi9W
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。656Please respect copyright.ＰＥＮＡＮＡaaUkyk2Sec
656Please respect copyright.ＰＥＮＡＮＡPDDLCLgJjn
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。656Please respect copyright.ＰＥＮＡＮＡM7uFrAYF9d
656Please respect copyright.ＰＥＮＡＮＡKphJQrjohd
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。656Please respect copyright.ＰＥＮＡＮＡyeCn4TN7i9
656Please respect copyright.ＰＥＮＡＮＡ2WrPziktbW
（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。656Please respect copyright.ＰＥＮＡＮＡLNu4gDcAg6
656Please respect copyright.ＰＥＮＡＮＡl71KYwJs7R
656Please respect copyright.ＰＥＮＡＮＡ8tKEKm330D
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。656Please respect copyright.ＰＥＮＡＮＡ107i9qw7KL
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。656Please respect copyright.ＰＥＮＡＮＡdhF55imc5c
