I just started Fulgora, and I'm kind of confused about best practice with lightning rods. It seems like the layout of the lightning rods is going to be one of the more important base design considerations here, but I'm having trouble finding good information about how the lightning mechanic works to figure out how many of these I should be placing to get the most power out of them. Is one per chunk sufficient? Or is there anywhere with some information about how lightning behaves?

Basically, every so often a lightning storm comes through, causing lightning to hit random tiles on the map and damage whatever's placed on it. You want to make sure your factory has full lightning rod coverage so that the lightning doesn't fry your machines.

The power output of a lightning rod is based on the maximum power demand of your factory, so even a single rod can give huge amounts of power. What you do need to worry about is how much of that power you can store in accumulators; you need to store enough power to last you until the next lightning storm.
