雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。575Please respect copyright.ＰＥＮＡＮＡGlu1j5yAJe
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。575Please respect copyright.ＰＥＮＡＮＡJJE8sN84Mw

（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。575Please respect copyright.ＰＥＮＡＮＡaGuHETIMi5
575Please respect copyright.ＰＥＮＡＮＡ7kEOw0HVw9
575Please respect copyright.ＰＥＮＡＮＡZA6c7k4kzb
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。575Please respect copyright.ＰＥＮＡＮＡmzFpNrXy5Y
575Please respect copyright.ＰＥＮＡＮＡmawFF6hJo7
（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。575Please respect copyright.ＰＥＮＡＮＡzw1wyJADRV

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。575Please respect copyright.ＰＥＮＡＮＡuK6HqZkjNY
575Please respect copyright.ＰＥＮＡＮＡzZfbus1hWq
575Please respect copyright.ＰＥＮＡＮＡReNfFap9wj
選用Fe(CN)6 –4的原因基於其兩種特質。575Please respect copyright.ＰＥＮＡＮＡPjDtkeoF9U
575Please respect copyright.ＰＥＮＡＮＡMp7kXhiImH
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。575Please respect copyright.ＰＥＮＡＮＡiC5rJxxqx9
575Please respect copyright.ＰＥＮＡＮＡQqRULPATGF
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。575Please respect copyright.ＰＥＮＡＮＡsrPWvuc0tw
575Please respect copyright.ＰＥＮＡＮＡTypjwQnjH2
（圖4）以下就是利用熱力發電的精髓要點。575Please respect copyright.ＰＥＮＡＮＡpONJepqZfF
575Please respect copyright.ＰＥＮＡＮＡ1uNAb7qNSL
575Please respect copyright.ＰＥＮＡＮＡejnRdySrXB
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。575Please respect copyright.ＰＥＮＡＮＡAPzndcs6Wf
575Please respect copyright.ＰＥＮＡＮＡbj4LV54OJU
2.電子在閉合電路走動，產生電流，讓燈泡發亮。575Please respect copyright.ＰＥＮＡＮＡ17iJGtD41Y
575Please respect copyright.ＰＥＮＡＮＡnrGzkKB0kh
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。575Please respect copyright.ＰＥＮＡＮＡzcnJ7TKRTb
575Please respect copyright.ＰＥＮＡＮＡ2dTBxPjRyE
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。575Please respect copyright.ＰＥＮＡＮＡBsQwrWlii6
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。575Please respect copyright.ＰＥＮＡＮＡeEInpHrNO3
575Please respect copyright.ＰＥＮＡＮＡ66hE97epAh
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。575Please respect copyright.ＰＥＮＡＮＡxYshwjHVsv
575Please respect copyright.ＰＥＮＡＮＡa6d9LhSnRe
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。575Please respect copyright.ＰＥＮＡＮＡ3m0kuuVAcw
575Please respect copyright.ＰＥＮＡＮＡfIDYELyfQD
（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。575Please respect copyright.ＰＥＮＡＮＡDLvQADm3f8
575Please respect copyright.ＰＥＮＡＮＡSmgSDy1asA
575Please respect copyright.ＰＥＮＡＮＡflsS3hnlMM
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。575Please respect copyright.ＰＥＮＡＮＡKo1Oobzwyv
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。575Please respect copyright.ＰＥＮＡＮＡlMWn8OQhjq
