雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。628Please respect copyright.ＰＥＮＡＮＡvsHXUEy7kF
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。628Please respect copyright.ＰＥＮＡＮＡhnco0SFQGv

（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。628Please respect copyright.ＰＥＮＡＮＡNJw9b4lVUF
628Please respect copyright.ＰＥＮＡＮＡW0p2Evt6PD
628Please respect copyright.ＰＥＮＡＮＡHI8Lfuce9K
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。628Please respect copyright.ＰＥＮＡＮＡmonNe6cySG
628Please respect copyright.ＰＥＮＡＮＡEhi4CXRzD0
（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。628Please respect copyright.ＰＥＮＡＮＡyV4mTXYq93
628Please respect copyright.ＰＥＮＡＮＡwb7JckfZQC
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。628Please respect copyright.ＰＥＮＡＮＡ81VDoGJqXK
628Please respect copyright.ＰＥＮＡＮＡtPZzEGXdxJ
628Please respect copyright.ＰＥＮＡＮＡo20dY25lsa
選用Fe(CN)6 –4的原因基於其兩種特質。628Please respect copyright.ＰＥＮＡＮＡrHpb775g6p
628Please respect copyright.ＰＥＮＡＮＡn9I0wLwmiF
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。628Please respect copyright.ＰＥＮＡＮＡAErYJx21mE
628Please respect copyright.ＰＥＮＡＮＡPEMGtSI70E
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。628Please respect copyright.ＰＥＮＡＮＡKsUFzZ7GQ1
628Please respect copyright.ＰＥＮＡＮＡl2tUDo4FBb
（圖4）以下就是利用熱力發電的精髓要點。628Please respect copyright.ＰＥＮＡＮＡ5ImfKiSAEQ

628Please respect copyright.ＰＥＮＡＮＡOGMHL2kR3k
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。628Please respect copyright.ＰＥＮＡＮＡ4jnTZjCF8I
628Please respect copyright.ＰＥＮＡＮＡVJqcgmuTGJ
2.電子在閉合電路走動，產生電流，讓燈泡發亮。628Please respect copyright.ＰＥＮＡＮＡABb4zb1CmD
628Please respect copyright.ＰＥＮＡＮＡBFLv5hweXb
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。628Please respect copyright.ＰＥＮＡＮＡxlGxxY8bZv
628Please respect copyright.ＰＥＮＡＮＡpZ5vsxY9wr
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。628Please respect copyright.ＰＥＮＡＮＡRb5zIgZppy
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。628Please respect copyright.ＰＥＮＡＮＡJpqdSFHSX0
628Please respect copyright.ＰＥＮＡＮＡ6UV6nhgrTO
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。628Please respect copyright.ＰＥＮＡＮＡXWjOMl7VFr
628Please respect copyright.ＰＥＮＡＮＡYbDvVlGqLj
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。628Please respect copyright.ＰＥＮＡＮＡBffy0okooE
628Please respect copyright.ＰＥＮＡＮＡ3gH0RsriAj
（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。628Please respect copyright.ＰＥＮＡＮＡzF9UPlbWZ7
628Please respect copyright.ＰＥＮＡＮＡUk57qvgJ2L
628Please respect copyright.ＰＥＮＡＮＡPHDTsUGZ9Q
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。628Please respect copyright.ＰＥＮＡＮＡVVLmuPZmi7
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。628Please respect copyright.ＰＥＮＡＮＡayKHzf0C66
