间接的，比如电厂汽轮机发电。
直接的，分为thermoelectric和thermionic两种。thermionic在工业界主要是高温区。
在汽车引擎的低温区thermoelectric热电转化的瓶颈，主要是功率的问题。类似光伏太
阳能器件，功率拉高了，对材料的寿命和转换效率的影响很大。
热电转换，一直是工业界和军工的热点难题。
呵呵
：汽车引擎能量转化效率25%-35%.
：如果热能到电能的转化效率也差不多，那电车也不会减少fossil fuel的用量啊。 |

reducing the current in the thermionic filament, until only one electron
appears on the screen, at any small interval of time. |
