雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。669Please respect copyright.ＰＥＮＡＮＡvzI40vRfVr
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。669Please respect copyright.ＰＥＮＡＮＡEmXWUV2Mic

（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。669Please respect copyright.ＰＥＮＡＮＡThO3FsWpZF
669Please respect copyright.ＰＥＮＡＮＡRBddwzdYb6
669Please respect copyright.ＰＥＮＡＮＡtH8oW2egPb
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。669Please respect copyright.ＰＥＮＡＮＡUIkVctJnSy
669Please respect copyright.ＰＥＮＡＮＡxpQjOd8lQD
（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。669Please respect copyright.ＰＥＮＡＮＡQM4SlZeUAa

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。669Please respect copyright.ＰＥＮＡＮＡgEttFZPeZg
669Please respect copyright.ＰＥＮＡＮＡbYfgdTYcMD
669Please respect copyright.ＰＥＮＡＮＡXkVQja8ATj
選用Fe(CN)6 –4的原因基於其兩種特質。669Please respect copyright.ＰＥＮＡＮＡkfN9OHszY9
669Please respect copyright.ＰＥＮＡＮＡpicXQRraZy
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。669Please respect copyright.ＰＥＮＡＮＡ15hUpPdG5Y
669Please respect copyright.ＰＥＮＡＮＡwOgQzL3VDE
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。669Please respect copyright.ＰＥＮＡＮＡSf2PjndGR1
669Please respect copyright.ＰＥＮＡＮＡ8feXzTXr5l
（圖4）以下就是利用熱力發電的精髓要點。669Please respect copyright.ＰＥＮＡＮＡ3mlGoogVjQ
669Please respect copyright.ＰＥＮＡＮＡW3TDNVJCVJ
669Please respect copyright.ＰＥＮＡＮＡmXeMi0okUA
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。669Please respect copyright.ＰＥＮＡＮＡJJYHKHZMuK
669Please respect copyright.ＰＥＮＡＮＡxGdYrjiU1R
2.電子在閉合電路走動，產生電流，讓燈泡發亮。669Please respect copyright.ＰＥＮＡＮＡvHNwNz3aIF
669Please respect copyright.ＰＥＮＡＮＡoifqBb4ri6
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。669Please respect copyright.ＰＥＮＡＮＡD28twlXbzr
669Please respect copyright.ＰＥＮＡＮＡztFKy35D1h
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。669Please respect copyright.ＰＥＮＡＮＡWLJOql6iP6
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。669Please respect copyright.ＰＥＮＡＮＡFpSZ4ZFe0Q
669Please respect copyright.ＰＥＮＡＮＡ6TVruy1jaR
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。669Please respect copyright.ＰＥＮＡＮＡ7Q6EZzPr3q
669Please respect copyright.ＰＥＮＡＮＡ4pDhOL1qlx
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。669Please respect copyright.ＰＥＮＡＮＡ2zJzJSlA4y
669Please respect copyright.ＰＥＮＡＮＡ2gF6HaA8Hr
（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。669Please respect copyright.ＰＥＮＡＮＡ5vbObwqXPO
669Please respect copyright.ＰＥＮＡＮＡ9xBojgaFKF
669Please respect copyright.ＰＥＮＡＮＡ22SdcZZnzM
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。669Please respect copyright.ＰＥＮＡＮＡ6jEKTOrUs9
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。669Please respect copyright.ＰＥＮＡＮＡWZ7zfY3f6p
