… Methods being researched for this purpose include MHD power generation, EHD power generation (electrohydrodynamic power generation), and thermionic power generation. Here, EHD power generation stands for electrohydrodynamic generator, which aims to generate electricity electrostatically by giving an electric charge to a high-temperature, high-velocity combustion gas and passing it between positive and negative electrodes placed in the direction of the flow. Thermionic power generation is a similar attempt to generate electricity electrostatically by using an electron flow emitted by thermionic electrons from a metal surface heated to a high temperature instead of the combustion gas mentioned above. … *Some of the terminology that refers to "electrohydrodynamic generator" is listed below.

… このような目的で研究されている方式としてはMHD発電のほか,EHD発電(電気流体発電),熱電子発電などがある。ここでEHD発電とは,高温高速の燃焼気体に電荷を与え,それを流れ方向に設置された正負電極の間に通して静電的に発電を行わそうとするもので,electrohydrodynamic generatorの意味である。また熱電子発電とは,上記燃焼気体の代りに,高温に加熱された金属表面から熱電子放出された電子流を用いて同様に静電的に発電を行わそうとするものである。… ※「electrohydrodynamic generator」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
