The present invention embodies a solid state thermionic energy converter and is directed to a method and apparatus (10 104, 108) for conversion of thermal , energy to electrical energy and electrical energy to refrigeration. The present invention maintains a thermal separation between an emitter (12) and a collector (16) through a fractional surface contact (13 42, 44) of decreasing , cross-sectional area towards the point of contact. The fractional surface contacts (13, 42, 44) may be associated with the emitter (12) a barrier (14), or the collector (16). Maintaining a thermal separation between the emitter (12) and the collector (16) provides for ballistic electron transport through …

Why it's free to use
- Filed March 6, 2000 and granted July 12, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 6, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 6, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
