According to Q-FFF string Theory, most eletromagnetic particles seem to be able to merge into an unstable string knot ( also called Higgs black holes) of 3 or 4 strings. Much larger knots are less unstable and form ball lightnings or micro comets radiating light for some stable time.
Two ways to make Higgs black hole alike Ball Lightning Nuclei powered by the broken vacuum.
Interference Tokamak Hotspots or ball lightning.

“Free Vacuum Energy from two Negative Charged Black Holes (string knots) in an electric adapted modern VAJRA"
Violation of the second law of thermodynamics.! by BL flight direction opposite to the local wind direction !!!
Multiple Lasers focussering to one point seem to form such knots easier than magnetic Tokamaks.
This could be the reason that lasers are better than Tokamaks.
