Some time ago, Fred or Horace (can't remember who) mentioned the connection between a particularly important voltage potential and a number of anomalous properties - one of which "could possibly" and coincidentally cross-relate between Ken Shoulder's all-important mass-energy value of 2 keV (he calls it a "narrow range') and the gravitomagnetic field. This figure turns up in the Claytor and Graneau work as well.
Of course getting a uniform 2 keV of electron mass-energy from a potential of 2 kV is no easy chore. But ignoring that problem for a moment... 2 keV is a value that does seem to have anecdotal importance - but I cannot remember the exact details of why - so maybe someone can provide the exact math. (If memory serves, it is related to the gradient value where the electron acceleration in the vector of the applied potential in free space is equal to c minus c*alpha ?? Jones
