I stand corrected, apparently West Africa gets the most lightning, something like 280 storm days per year. (no offense to Singapore who still beats us)
Also I heard it was the almight Ben Franklin who invented the first lightning rod. Interesting bits though, the most obvious place to put the first rods was the highest building around, the church. However some churchgoers initially thought that it was defying God's will to resist the lightning strikes, but apparently it was ok that they stay dry from the rain?
Also early lightning rods also incorporated glass balls which would shatter and fall off when struck, so you knew the rod was working. I think that's an important design consideration, people want to know that their stuff is working and shattering glass is much more dramatic than just "not getting killed by lightning".
