雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。623Please respect copyright.ＰＥＮＡＮＡEm9d16sBtF
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。623Please respect copyright.ＰＥＮＡＮＡRtaURACWu9

（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。623Please respect copyright.ＰＥＮＡＮＡAv0ufJ17Bp
623Please respect copyright.ＰＥＮＡＮＡ3K8hE5bzaS
623Please respect copyright.ＰＥＮＡＮＡ8HjCw26CBC
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。623Please respect copyright.ＰＥＮＡＮＡEjatppeztU
623Please respect copyright.ＰＥＮＡＮＡWYsotYOmNp
（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。623Please respect copyright.ＰＥＮＡＮＡPFk0ffPu9p

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。623Please respect copyright.ＰＥＮＡＮＡAKFyznzYTh
623Please respect copyright.ＰＥＮＡＮＡOhEE0knfev
623Please respect copyright.ＰＥＮＡＮＡVu49GTV4cR
選用Fe(CN)6 –4的原因基於其兩種特質。623Please respect copyright.ＰＥＮＡＮＡ8QVff9YhxZ
623Please respect copyright.ＰＥＮＡＮＡ1JrcWWcDD0
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。623Please respect copyright.ＰＥＮＡＮＡWCVju4vhHd
623Please respect copyright.ＰＥＮＡＮＡe7iGNvWZtf
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。623Please respect copyright.ＰＥＮＡＮＡ7Ltw1WjBUg
623Please respect copyright.ＰＥＮＡＮＡwQDnyRpYCq
（圖4）以下就是利用熱力發電的精髓要點。623Please respect copyright.ＰＥＮＡＮＡxjkI4KTV0S
623Please respect copyright.ＰＥＮＡＮＡItScoZhwTu
623Please respect copyright.ＰＥＮＡＮＡwkKTOjSr1m
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。623Please respect copyright.ＰＥＮＡＮＡS7ZGInxWK2
623Please respect copyright.ＰＥＮＡＮＡej5CTtLvhh
2.電子在閉合電路走動，產生電流，讓燈泡發亮。623Please respect copyright.ＰＥＮＡＮＡ9Z3wjczEyC
623Please respect copyright.ＰＥＮＡＮＡXMSEK4xfkm
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。623Please respect copyright.ＰＥＮＡＮＡHppmlKMWjt
623Please respect copyright.ＰＥＮＡＮＡu1Z6VffCn9
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。623Please respect copyright.ＰＥＮＡＮＡQjIUZJLRot
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。623Please respect copyright.ＰＥＮＡＮＡnxcdTmH064
623Please respect copyright.ＰＥＮＡＮＡKTI7EOImQd
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。623Please respect copyright.ＰＥＮＡＮＡzrPXy0SpuU
623Please respect copyright.ＰＥＮＡＮＡCMmO9h6wY4
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。623Please respect copyright.ＰＥＮＡＮＡue4CFHul7p
623Please respect copyright.ＰＥＮＡＮＡ5PnFlEXOFc
（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。623Please respect copyright.ＰＥＮＡＮＡemHuDEkiVU
623Please respect copyright.ＰＥＮＡＮＡGuQL2TVGO3
623Please respect copyright.ＰＥＮＡＮＡaRnccKHbAx
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。623Please respect copyright.ＰＥＮＡＮＡb4CSI2UzWk
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。623Please respect copyright.ＰＥＮＡＮＡY8k3p25AUw
