(Nanowerk News) Through a process known as thermionic conversion, heat energy -- such as light from the sun or heat from burned fossil fuels -- can be converted into electricity with very high ...

Arxiv – Thermionics (electronics for converting heat to electricity) previously had efficiency limitations due to “space current” – build-ups of electrons mutually repelling each other and choking the ...

(Nanowerk Spotlight) Heat energy can be converted into electricity with very high efficiency through a temperature-induced electron flow process known as thermionic emission. The basic operating ...

An evaluation of the many new devices proposed, in recent years, for power production. Among these are fuel cells, thermoelectric generators, thermionic generators, and solar cells. Comparisons of ...

Researchers discover a new theory that paves the way for the design of better graphene electronics and energy converters. When a metal is heated to a sufficiently high temperature, electrons can be ...

GIBRALTAR, Iceland--(BUSINESS WIRE)--Dec. 1, 2003--A hybrid electric automobile using thermionic devices to drive electric motors could provide an efficient and low cost alternative to current designs ...

So rapid have been the advances made in radiotele-graphy and radio telephony that the author has found it necessary to rewrite much of the first edition of this useful book. The invention of the ...
