What is the minimum formation energy required for a ball lighting phenomena? Could it possibly form in a sub station or circuit if there is a fault ? https://en.wikipedia.org/wiki/Ball_lightning#Vaporized_silicon_hypothesis I wonder if a blown transistor can make it possibly to fuck something else up in a circuit? (in a one in a million odds).. |

Most current research points to "ball lightning" as a neurological condition triggered by strong electromagnetic fields. |

its on high speed video at least read the wikipedia article. these are interesting too, it looks kinda like high life time welding spatter ftp://ftp.aip.org/epaps/phys_rev_lett/E-PRLTAO-98-047705/ i think thats a silicone rod or substrate. imagine that flying in side of a enclosure. |

We have experienced a ball lightning. A lightning went past our workshop and continued past the house, between the house and rainwater drums. In the workshop we lost a printer and a PC while th actual lightning was eyewitnessed by our mother. A few seconds had elapsed and a loud bang was heard in the village down the road from us followed by a whole bunch of alarms going off. |

While I like Helius' explanation ;D the weight of evidence seems to be leaning towards the "it's dirt" theories. Some Chinese researchers seem to have captured a spectrum on film: https://physics.aps.org/articles/v7/5 Apparently, so the theory goes, a lightning strike vaporizes some soil constituents which can then form the luminous burning ball. This seems to explain a number of observations, but not all, e.g. the well attested sightings on aircraft. It is not at all clear that the ball-like discharges obtained in laboratories are the same thing as naturally occurring ball lightning, so the OP's question is impossible to answer. |
