Why the emotional response?

I just searched altavista for "lightning detector."  Several hits, one
looks like the same device.  No info though.

Anyone remember the "lightning mapper" project in Amateur Scientist SciAm
years ago?  It basically was a VLF radio direction finding circuit, with
crossed loop antennas going to X-Y on a CRT, and a field sampling antenna
functioning to darken the trace so the spikes of light on the CRT screen
would point out the proper compass direction to the impulses.  I remember
being in 5th grade and having grand dreams of building such a thing
someday.

Much easier today to buy one out of the back of Weatherwise magazine.  One
company sells one which interfaces to a PC and plots lightning azimuth and
direction on an XY display.
