雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。668Please respect copyright.ＰＥＮＡＮＡ7BmqxdcvuU
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。668Please respect copyright.ＰＥＮＡＮＡFXCOR7prHP

（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。668Please respect copyright.ＰＥＮＡＮＡDWo1U9MTx8

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。668Please respect copyright.ＰＥＮＡＮＡPxjYWF566S
668Please respect copyright.ＰＥＮＡＮＡAGd61Zq1Ei
（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。668Please respect copyright.ＰＥＮＡＮＡxztoJTCBZg

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。668Please respect copyright.ＰＥＮＡＮＡRGRatHNDAz
668Please respect copyright.ＰＥＮＡＮＡ9osbMw3No4
668Please respect copyright.ＰＥＮＡＮＡxbGoqA5DNQ
選用Fe(CN)6 –4的原因基於其兩種特質。668Please respect copyright.ＰＥＮＡＮＡzTlgNpLe63
668Please respect copyright.ＰＥＮＡＮＡ4kwZewHkgv
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。668Please respect copyright.ＰＥＮＡＮＡ9byy5O32hH
668Please respect copyright.ＰＥＮＡＮＡLDU8PGvaW6
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。668Please respect copyright.ＰＥＮＡＮＡZjMlP27jgo
668Please respect copyright.ＰＥＮＡＮＡkj80c3vGvq
（圖4）以下就是利用熱力發電的精髓要點。668Please respect copyright.ＰＥＮＡＮＡYWBrLbCXOU

668Please respect copyright.ＰＥＮＡＮＡgBBxzgPXSd
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。668Please respect copyright.ＰＥＮＡＮＡOlNsfzXXk2
668Please respect copyright.ＰＥＮＡＮＡyYBP02rVn5
2.電子在閉合電路走動，產生電流，讓燈泡發亮。668Please respect copyright.ＰＥＮＡＮＡAETQiBnjSZ
668Please respect copyright.ＰＥＮＡＮＡTAK6on9ZnV
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。668Please respect copyright.ＰＥＮＡＮＡEDtJNW0UDk
668Please respect copyright.ＰＥＮＡＮＡA94V4A2JBJ
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。668Please respect copyright.ＰＥＮＡＮＡjvBFV3LXx3
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。668Please respect copyright.ＰＥＮＡＮＡVq05tZOLbj
668Please respect copyright.ＰＥＮＡＮＡsYamCxGdpI
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。668Please respect copyright.ＰＥＮＡＮＡwLOpvpr3UG
668Please respect copyright.ＰＥＮＡＮＡRrYF2P6Dkp
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。668Please respect copyright.ＰＥＮＡＮＡDA66vtEuSP
668Please respect copyright.ＰＥＮＡＮＡbs5nVCBYQf
（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。668Please respect copyright.ＰＥＮＡＮＡdgpz3u55RL
668Please respect copyright.ＰＥＮＡＮＡ1rTSfykUcK
668Please respect copyright.ＰＥＮＡＮＡkXNlJVQhGG
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。668Please respect copyright.ＰＥＮＡＮＡnV7f83cj53
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。668Please respect copyright.ＰＥＮＡＮＡxtq9rljFif
