    Thanks to @Director for passing this onto me. This reminds me of something being shown around by an Italian guy, but I'm damned if I can remember who.

    Resonant Vacuum Arc Discharge Apparatus for Nuclear Fusion (Federally sponsored research)

    Abstract

    The present invention relates to a resonant vacuum arc discharge apparatus for producing nuclear fusion. A resonant high-frequency high-voltage alternating current (AC) power supply is used to efficiently power a fusion tube normally containing deuterium, tritium and/or helium-3 vapor. Metals that can hold large amounts of hydrogen isotopes such as palladium and titanium can be used to increase the target density. The nuclear fusion device can be used for energy production, well logging, uranium mining, neutron activation analysis, isotope production or other applications that require a neutron source.

    This lapsed patent is evidence that such plasma-based LENR systems (similar to the SK) are probably very difficult to construct and operate efficiently - all very well in theory but in practice a bit of a nightmare operating at potentially lethal voltage levels.

    Funnily enough Russ put a lot of prior art for this on the internet 20 years or so ago- his neon-sign derived glow-discharge tube that produced meshuggenons. The sputter-capture rings by the electrodes in the patent are a refinement to overcome a problem (gradual coating of the inside of the tube with sputtered metal until it arcs across) but much of the rest is worthless because of prior art. He doubts the patent author ever built the device illustrated.

    Quote from Alan Smith

    It means the fees have not been paid. I'm not sure how much grace (if any) is allowed, but basically the IP is free and clear.

    The IP is free and clear, but this is not a patent that was abandoned because fees were not paid. This is a patent application that was abandoned, likely because it became clear to the inventor that it would never be issued as a patent.


    From the public PAIR site, I looked up the application and found the following which I have edited to remove the uninteresting parts:

    He responded to one rejection, had an interview with the examiner, then gave up when he got the next rejection. The file history shows six patents that were cited as prior art including this one with James Patterson as sole inventor:
