*Below is a quote from a scientific paper about measurements of energy in
an average lighting strike. My question: What's* MJ/m? Stan
"The energy released by lightning is measured in megajoules, also expressed
as MJ/m."
“For example a single megajoule is equivalent to about 200 food calories,

It might be the energy dissipated in air by the arc. Once the arc is struck,
the voltage drop (per meter) is relatively low, MUCH less than the initial
brekdown voltage.
