雪櫃、冷氣機、水煲等等各電器不時都會散發出熱力。714Please respect copyright.ＰＥＮＡＮＡ7BYFPx9Rvy
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。714Please respect copyright.ＰＥＮＡＮＡB1CYkf4XYt

（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。714Please respect copyright.ＰＥＮＡＮＡKIcGNlnymV
714Please respect copyright.ＰＥＮＡＮＡkjijcYjWre
714Please respect copyright.ＰＥＮＡＮＡlYFkp2y9dM
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。714Please respect copyright.ＰＥＮＡＮＡogU8znWpea
714Please respect copyright.ＰＥＮＡＮＡci2eGySTdI
（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。714Please respect copyright.ＰＥＮＡＮＡJYB6E0KaIQ
714Please respect copyright.ＰＥＮＡＮＡ6npoFVC60W
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。714Please respect copyright.ＰＥＮＡＮＡovruxtA8Dv
714Please respect copyright.ＰＥＮＡＮＡBfgd1wR4Ks
714Please respect copyright.ＰＥＮＡＮＡW7tPx467fQ
選用Fe(CN)6 –4的原因基於其兩種特質。714Please respect copyright.ＰＥＮＡＮＡR2Ck1YxBfP
714Please respect copyright.ＰＥＮＡＮＡsxDkWjjyX4
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。714Please respect copyright.ＰＥＮＡＮＡxNszy1iHOm
714Please respect copyright.ＰＥＮＡＮＡB2ejrWXjbR
2.它遇熱的時候會放出電子並成為Fe(CN)6 –3。714Please respect copyright.ＰＥＮＡＮＡnxBiErlXNu
714Please respect copyright.ＰＥＮＡＮＡvO4PnON1t5
（圖4）以下就是利用熱力發電的精髓要點。714Please respect copyright.ＰＥＮＡＮＡRqJLWDanAp

714Please respect copyright.ＰＥＮＡＮＡ9SCz4aUW84
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。714Please respect copyright.ＰＥＮＡＮＡJh1bh5evLd
714Please respect copyright.ＰＥＮＡＮＡnm8Ysa0ILr
2.電子在閉合電路走動，產生電流，讓燈泡發亮。714Please respect copyright.ＰＥＮＡＮＡum51LLUZLJ
714Please respect copyright.ＰＥＮＡＮＡjHvB7nMOpu
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。714Please respect copyright.ＰＥＮＡＮＡLNqg3iINDF
714Please respect copyright.ＰＥＮＡＮＡO375vmRP2h
4.Fe(CN)6 –4在Guanidinium ion的輔助下變成固體結晶。714Please respect copyright.ＰＥＮＡＮＡLfQpskBEdQ
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。714Please respect copyright.ＰＥＮＡＮＡ4zEmNoYpet
714Please respect copyright.ＰＥＮＡＮＡQdhZCkX14b
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。714Please respect copyright.ＰＥＮＡＮＡ6DcmphtaYg
714Please respect copyright.ＰＥＮＡＮＡZSPgPJQ9sX
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。714Please respect copyright.ＰＥＮＡＮＡQ5drrdXpzH
714Please respect copyright.ＰＥＮＡＮＡQ2xGLK1W5F
（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。714Please respect copyright.ＰＥＮＡＮＡA9aCYJ9GB9
714Please respect copyright.ＰＥＮＡＮＡrDGiYBvkL2
714Please respect copyright.ＰＥＮＡＮＡkLR0503nJ0
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。714Please respect copyright.ＰＥＮＡＮＡkbquijRoqy
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。714Please respect copyright.ＰＥＮＡＮＡaczEFTG0zz
