Apparently a single lightning strike contains the equivalent of about 40 gallons of gasoline. It’s very powerful but not that significant on the scale of a whole city.

In fact a quick back of the napkin math suggests it would only power a city of a million people for half a second.

This comment made me wonder about the idea of harvesting lightning as a power source. Obviously it’s incredibly challenging, but I wondered if we had magic sci-fi technology that allowed it, how useful would it be?

Back of the napkin math suggests that even with theoretically perfect prediction, capture, storage and distribution you’d still get at best ~1% of the US’ energy through lightning capture.

  • We don't even universally accept that sun and wind could be enough to power everything we ever want to do. Not sure how well lightning harvesting will be received.

I wonder what the average property damage is per strike. And if forcing lightning reduces or changes storm power. Maybe for preventative reasons you put them outside of towns and such.
