Neutron Bursts in Lab Lightning "nuclear reactions occur in lightning. However, physicists have been unable to identify which reactions" ..."which process initiates the discharge is still a matter of debate" We here at vortex know that LENR is an electromagnetic based reaction. "The neutron flux fell off more slowly than the inverse distance squared (1/ r 2 ), implying that the neutrons originate from an extended region, rather than a localized point. " Whenever the electric flow is favorable(vortex circulation), LENR will occur. By the way, transmutation also happens in lightning.
