Perhaps just for comparison, during the discharge (only!) of an average lightning (lasting from 100 to 150 millionths of a second) is above ground, also underground radiated energy, thanks to that would long and loaded freight train (thousands of tons) travel several tens of kilometers, and a full loaded truck (tens of tons) hundreds or thousands of kilometers.
Marahil ay para lamang sa paghahambing, sa panahon ng paglabas (only!) ng isang average na kidlat (walang pagkupas mula sa 100 150 millionths ng isang segundo) sa itaas lupa, underground din radiated enerhiya, salamat sa Iyon ba mahaba at-load kargamento tren (Libo-libong mga ton) ilang travel sampu ng mga kilometro, at isang buong-load trak (sampu-sampung tonelada) Libo-libo o daan-daang mga kilometro.
