雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。662Please respect copyright.ＰＥＮＡＮＡfLs09GXnp4
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。662Please respect copyright.ＰＥＮＡＮＡ3rDvBLJCAA

（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。662Please respect copyright.ＰＥＮＡＮＡlrAqBiwX1D
662Please respect copyright.ＰＥＮＡＮＡbF9MmJbwPZ
662Please respect copyright.ＰＥＮＡＮＡxqM1TRyjnK
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。662Please respect copyright.ＰＥＮＡＮＡuGjOBg8r6T
662Please respect copyright.ＰＥＮＡＮＡZdLVWFhMX5
（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。662Please respect copyright.ＰＥＮＡＮＡnEG9PwVfPc

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。662Please respect copyright.ＰＥＮＡＮＡfYxHGhHbvu
662Please respect copyright.ＰＥＮＡＮＡZlyz5JitIh
662Please respect copyright.ＰＥＮＡＮＡqvwcItObRy
選用Fe(CN)6 –4的原因基於其兩種特質。662Please respect copyright.ＰＥＮＡＮＡgk8KLoFClz
662Please respect copyright.ＰＥＮＡＮＡi9JBX1cnQV
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。662Please respect copyright.ＰＥＮＡＮＡOMG7zweUUr
662Please respect copyright.ＰＥＮＡＮＡgps5acZUQr
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。662Please respect copyright.ＰＥＮＡＮＡx88NkDcVvI
662Please respect copyright.ＰＥＮＡＮＡyp8w99Xa5A
（圖4）以下就是利用熱力發電的精髓要點。662Please respect copyright.ＰＥＮＡＮＡ56G3Za5ttT

662Please respect copyright.ＰＥＮＡＮＡq99Z3QMMXb
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。662Please respect copyright.ＰＥＮＡＮＡD21yXyIGja
662Please respect copyright.ＰＥＮＡＮＡ7xFj0FiBdt
2.電子在閉合電路走動，產生電流，讓燈泡發亮。662Please respect copyright.ＰＥＮＡＮＡDbuqbcFpf9
662Please respect copyright.ＰＥＮＡＮＡcY9MnICTrT
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。662Please respect copyright.ＰＥＮＡＮＡE0scMGwdu4
662Please respect copyright.ＰＥＮＡＮＡa1BKrYAbCL
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。662Please respect copyright.ＰＥＮＡＮＡ7rV6dUFy1N
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。662Please respect copyright.ＰＥＮＡＮＡgy4LSTXTz0
662Please respect copyright.ＰＥＮＡＮＡXbzGwc34qN
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。662Please respect copyright.ＰＥＮＡＮＡXVbyoWKTAr
662Please respect copyright.ＰＥＮＡＮＡUEzOJ2X8bT
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。662Please respect copyright.ＰＥＮＡＮＡ25QSyVh4Ho
662Please respect copyright.ＰＥＮＡＮＡ3rVJ6Wrt4R
（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。662Please respect copyright.ＰＥＮＡＮＡIy4Zp4GmPA
662Please respect copyright.ＰＥＮＡＮＡl3P4OfF0H0
662Please respect copyright.ＰＥＮＡＮＡqyFC9Sfk4z
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。662Please respect copyright.ＰＥＮＡＮＡjEpnYbqbji
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。662Please respect copyright.ＰＥＮＡＮＡJa7uCSJ7Ij
