雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。698Please respect copyright.ＰＥＮＡＮＡjQDnuFMTcD
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。698Please respect copyright.ＰＥＮＡＮＡyXkMUyBjdH

（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。698Please respect copyright.ＰＥＮＡＮＡ8Q8roIOWdP
698Please respect copyright.ＰＥＮＡＮＡF998wTLuyf
698Please respect copyright.ＰＥＮＡＮＡkncqmzHZQm
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。698Please respect copyright.ＰＥＮＡＮＡXhry2xqoec
698Please respect copyright.ＰＥＮＡＮＡb0OU4Kkan5
（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。698Please respect copyright.ＰＥＮＡＮＡW4SOj5VS6C

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。698Please respect copyright.ＰＥＮＡＮＡuSH2ZwVKMq
698Please respect copyright.ＰＥＮＡＮＡKMCa3Jp4Bt
698Please respect copyright.ＰＥＮＡＮＡ7Wv5pW0uFK
選用Fe(CN)6 –4的原因基於其兩種特質。698Please respect copyright.ＰＥＮＡＮＡ4M4wHKUvy2
698Please respect copyright.ＰＥＮＡＮＡWI6uEu0kBr
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。698Please respect copyright.ＰＥＮＡＮＡQ3ThjfhcpS
698Please respect copyright.ＰＥＮＡＮＡ34MaZYHSrv
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。698Please respect copyright.ＰＥＮＡＮＡV325b3CNnZ
698Please respect copyright.ＰＥＮＡＮＡzdHbf8RDHI
（圖4）以下就是利用熱力發電的精髓要點。698Please respect copyright.ＰＥＮＡＮＡYgopbnMBo2

698Please respect copyright.ＰＥＮＡＮＡ5UNuLFiFRW
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。698Please respect copyright.ＰＥＮＡＮＡKRxevxpPH1
698Please respect copyright.ＰＥＮＡＮＡI0VEjxDAzJ
2.電子在閉合電路走動，產生電流，讓燈泡發亮。698Please respect copyright.ＰＥＮＡＮＡBjqCp7qkLY
698Please respect copyright.ＰＥＮＡＮＡ8ChQgalbDL
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。698Please respect copyright.ＰＥＮＡＮＡxJAC8bAWGC
698Please respect copyright.ＰＥＮＡＮＡ48OPAJQkh3
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。698Please respect copyright.ＰＥＮＡＮＡUveciCRnZR
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。698Please respect copyright.ＰＥＮＡＮＡfMdONlmYmu
698Please respect copyright.ＰＥＮＡＮＡ5K50GfscmZ
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。698Please respect copyright.ＰＥＮＡＮＡ0PtbwQK73G
698Please respect copyright.ＰＥＮＡＮＡo42coa9qOs
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。698Please respect copyright.ＰＥＮＡＮＡAg4C8PT92t
698Please respect copyright.ＰＥＮＡＮＡOhxTRod3YR
（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。698Please respect copyright.ＰＥＮＡＮＡZetyW48caD
698Please respect copyright.ＰＥＮＡＮＡluq9uJxCIR
698Please respect copyright.ＰＥＮＡＮＡ1G9qxeOa1p
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。698Please respect copyright.ＰＥＮＡＮＡARoH5iQdXP
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。698Please respect copyright.ＰＥＮＡＮＡeITawDvNgE
