Photon-enhanced thermionic emission is a method of solar-energy conversion that promises to combine photon and thermal processes into a single mechanism, overcoming fundamental limits on the ...

However, [Nick Poole] wanted to investigate an alternative method, using thermionic converters for solar power generation. [Nick] has been gearing up to produce various styles of vacuum tubes ...

Unencumbered by a deep understanding of how vacuum tubes work, [Nick] proceeds to fill this void by imagining Integrated Thermionic, a fictitious company that exists in an alternate history where ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 13, No. 2 (Feb. 15, 1927), pp. 43-46 (4 pages) ...

Ubiquitous in the field of electric propulsion, thermionic hollow cathodes are electron sources which utilize thermionic emission from a low work function insert material to achieve large extracted ...

1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born. The principle of ...

He began to reanalyze thermionic energy conversion technology that was used by NASA in the 1950s and 1960s. From there, he used his knowledge and skills gained from the Purdue Certificate in ...
