Look up "ball lightning" (with quotes) in the Google custom search box at LENR-CANR.org and you will see that several people have speculated about this. Especially E. Lewis, as noted:

Sci. 2 (2009) 13–32 > http://www.lenr-canr.org/acrobat/LewisEtracksofba.pdf I just added this to the index: Lewis, E., *More Evidence of Microscopic Ball Lightning (Plasmoids) in CF Devices.* J. Condensed Matter Nucl. Sci., 2012. *7*. http://lenr-canr.org/acrobat/BiberianJPjcondensedf.pdf#page=13 - Jed
