雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。613Please respect copyright.ＰＥＮＡＮＡlLCGTMPC6C
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。613Please respect copyright.ＰＥＮＡＮＡRFOJu2bOmi

（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。613Please respect copyright.ＰＥＮＡＮＡHKdENnPB0s
613Please respect copyright.ＰＥＮＡＮＡop08IpjPIZ
613Please respect copyright.ＰＥＮＡＮＡ2HcSifQO9G
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。613Please respect copyright.ＰＥＮＡＮＡqhUK147Jt8
613Please respect copyright.ＰＥＮＡＮＡD0UtqamKeE
（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。613Please respect copyright.ＰＥＮＡＮＡw50vF0XhaX

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。613Please respect copyright.ＰＥＮＡＮＡoXl8ygx2p9
613Please respect copyright.ＰＥＮＡＮＡBnzZZGzm4v
613Please respect copyright.ＰＥＮＡＮＡkpXHbJKVZk
選用Fe(CN)6 –4的原因基於其兩種特質。613Please respect copyright.ＰＥＮＡＮＡL18yHrHZlj
613Please respect copyright.ＰＥＮＡＮＡtgEB74HBPp
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。613Please respect copyright.ＰＥＮＡＮＡb8FIymsmZA
613Please respect copyright.ＰＥＮＡＮＡfW1wwrZs7K
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。613Please respect copyright.ＰＥＮＡＮＡkfASyffwK0
613Please respect copyright.ＰＥＮＡＮＡmLcuYJJxnV
（圖4）以下就是利用熱力發電的精髓要點。613Please respect copyright.ＰＥＮＡＮＡntFLRj0AWQ
613Please respect copyright.ＰＥＮＡＮＡTQjCHqID89
613Please respect copyright.ＰＥＮＡＮＡhDT1tT4UPV
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。613Please respect copyright.ＰＥＮＡＮＡWPDVtJAPYM
613Please respect copyright.ＰＥＮＡＮＡirGBcA4bpZ
2.電子在閉合電路走動，產生電流，讓燈泡發亮。613Please respect copyright.ＰＥＮＡＮＡuoJV8EnhcV
613Please respect copyright.ＰＥＮＡＮＡzuHQRiZof8
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。613Please respect copyright.ＰＥＮＡＮＡwSNbSvbUOG
613Please respect copyright.ＰＥＮＡＮＡ7JYvS8ks9a
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。613Please respect copyright.ＰＥＮＡＮＡfa4maiYS2C
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。613Please respect copyright.ＰＥＮＡＮＡrW9jSJ8xn3
613Please respect copyright.ＰＥＮＡＮＡyL7LPm2b9n
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。613Please respect copyright.ＰＥＮＡＮＡUtA3U6bYDE
613Please respect copyright.ＰＥＮＡＮＡTo9LsAnJct
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。613Please respect copyright.ＰＥＮＡＮＡj5BjtnwBGA
613Please respect copyright.ＰＥＮＡＮＡPdE6TKw99n
（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。613Please respect copyright.ＰＥＮＡＮＡd7kwiuqGgv
613Please respect copyright.ＰＥＮＡＮＡsxImegTC8s
613Please respect copyright.ＰＥＮＡＮＡUtNwyffH1Q
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。613Please respect copyright.ＰＥＮＡＮＡ69b1bUKmz2
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。613Please respect copyright.ＰＥＮＡＮＡjCAdcmgtoy
