Cool. I had never heard of Franklin bells. An interesting read.

It's certainly a lightning detector, too, although I guess it will detect only hits -- no distant lightning.

It will also detect an atmospheric potential gradient, even in the absence of lightning. Such a gradient nearly always exists, but it's stronger when clouds are present -- especially clouds that grow vertically, like cumulonimbus.

I didn't know any of this (except the part about clouds and electric gradients) until you set me reading, LYT. Thanks!
