The new Scientific American has a nice article about how lightning starts
and the X-rays they are now finding in lighting strikes! About 250,000
eV. Great article for those that are interested in lightning ;-)

Along the lines of lightning tests..
Has anyone here in the US that's an IEEE member read the
article in this month's issue titled "Stealing Celestial
Fire" ? It looks to be along the lines of the 'N2 laser
triggered spark gap' thread we had awhile back..
For those of you who haven't read it..
They're using a Teramobile (titanium sapphire) laser to
create a plasma channel between a charged electrode and a
grond point. The laser is capable of 100 fempto-second
pulses with a max power of 5 terawatts. Rips the electrons
right form the air, creating what they're calling a
'filament'. From the pictures it looks like one heck of a
triggered gap. The idea is to scale it up a bit to reduce
lightning strikes at airports.
Someday I'll have a job like this.. ;)
