雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。868Please respect copyright.ＰＥＮＡＮＡr17c301H2G
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。868Please respect copyright.ＰＥＮＡＮＡZC9Ezz5eBH

（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。868Please respect copyright.ＰＥＮＡＮＡ19KSbPDpTm
868Please respect copyright.ＰＥＮＡＮＡ34GajxS6IR
868Please respect copyright.ＰＥＮＡＮＡYxmSkxvgOn
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。868Please respect copyright.ＰＥＮＡＮＡNXbheCIvEw
868Please respect copyright.ＰＥＮＡＮＡ0mdb2DjawA
（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。868Please respect copyright.ＰＥＮＡＮＡfePvzIgI26

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。868Please respect copyright.ＰＥＮＡＮＡw5I5HBJYZF
868Please respect copyright.ＰＥＮＡＮＡZgISjdJpgd
868Please respect copyright.ＰＥＮＡＮＡopF8OcnB3u
選用Fe(CN)6 –4的原因基於其兩種特質。868Please respect copyright.ＰＥＮＡＮＡQLq31BZ3dR
868Please respect copyright.ＰＥＮＡＮＡY4Mux7ijEu
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。868Please respect copyright.ＰＥＮＡＮＡ8oYCXHxLkW
868Please respect copyright.ＰＥＮＡＮＡ1UIA3yGNJu
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。868Please respect copyright.ＰＥＮＡＮＡZwrR1oLF7x
868Please respect copyright.ＰＥＮＡＮＡLoRbDCJek4
（圖4）以下就是利用熱力發電的精髓要點。868Please respect copyright.ＰＥＮＡＮＡmMk3RWFuk0

868Please respect copyright.ＰＥＮＡＮＡoEavNZzkuf
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。868Please respect copyright.ＰＥＮＡＮＡm4uw3hgR4s
868Please respect copyright.ＰＥＮＡＮＡMpOt4kb2sm
2.電子在閉合電路走動，產生電流，讓燈泡發亮。868Please respect copyright.ＰＥＮＡＮＡG7BTlmbj9T
868Please respect copyright.ＰＥＮＡＮＡrArhlp5MGH
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。868Please respect copyright.ＰＥＮＡＮＡbmXAufD3RV
868Please respect copyright.ＰＥＮＡＮＡifRvgt9NGa
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。868Please respect copyright.ＰＥＮＡＮＡGM7Wqtd5DA
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。868Please respect copyright.ＰＥＮＡＮＡa2tHecjSQg
868Please respect copyright.ＰＥＮＡＮＡNboDHjhLzf
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。868Please respect copyright.ＰＥＮＡＮＡsPrPy9XGjK
868Please respect copyright.ＰＥＮＡＮＡr27l8cnFcP
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。868Please respect copyright.ＰＥＮＡＮＡv9Z0Zh9N1G
868Please respect copyright.ＰＥＮＡＮＡBKCV0tficz
（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。868Please respect copyright.ＰＥＮＡＮＡqFzFZLKx0n
868Please respect copyright.ＰＥＮＡＮＡhmVs9iQt82
868Please respect copyright.ＰＥＮＡＮＡ1MMxShFtY7
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。868Please respect copyright.ＰＥＮＡＮＡj1b13nrOSM
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。868Please respect copyright.ＰＥＮＡＮＡWwrrexs5EZ
