xx (Q-FFF Theory) postulates that you only need 3x magnetic- or 4x x-ray strings to form a real string KNOT which is the base for an unstable micro black hole or ball lightning.(image below)
If the string knot is much larger, it will become more stable and it will last longer before the balllightning will die. ( see image of the splitting ball lightning falling from the pole below)
Recent NIF ( Livermore) observations of 2x laser focuss interference points seem to support this phenomenon. (see image) and report the production of extra output energy obove the imput laser energy.
According to Q-FFF Theory, inside the focuss points, series of string knots will produce lots of Fermion pairs (- and + or energy boiling) out of the ( Axion-Higgs) oscillating string vacuum, wich remain entangled just as in the big bang Herbig Haro dual blackhole process.
However The NIF uses lots of energy which seems to be not needed to for such photon knots. Only good focussing seems to be needed to form ball lightning free energy effects.
Even the Nijmegen (NL) FEL seems be a good start.

The Q-FFF Theory says: there are no point particles, only Rigid STRINGS making even Black Holes, it is postulating the raspberry Multiverse as a base for uncertainty (ER=EPR) and Libet's consciousness measurements (RPI and RPII).
