When I was about 10, I was impressed by a tv show (I believe it was NOVA) on PBS, that demonstrated college students attracting lightning with wires and rockets. I remember they had some equipment that would tell them a somewhat optimum time to fire it. Does anyone know what equipment that was and maybe where I could find their research? I remember they were making sand castings of lightning in 5gal buckets and actually succeded a few times, but I can't find them anywhere or remember what university they were with.

I have this Nova 'Lightning' on Dvd,
it contains footage of guys in Florida, and the Langmuir Laboratory in New Mexico,
who fire rockets into storm clouds with the intent to attract lighning into buckets of sand with the hope of discovering a new form of carbon.

I saw an episode like that a few months ago. Did you check the nova site, they might have an episode list with info?

Mike> Yeah, no results.

But Bennem, that sounds like the show I'm talking about; is that the title? There's one at NOVA's site called "Lightning!" but it's about the dangers of lightning and what it causes or something.

Google did return a site on New Mexico Tech's website, but their server is apparently down right now. frown But now I know what to look for. Thanks!


EDIT=> SWEET! I found some pics! Link2
What's up with the banjo effect in the last one? confused

Hi Part Scavenger,
The Dvd i have is by Nova titled 'Killer Twisters and Super storms'
it has two episodes on one disc.
On the disc it says 'Super storms as seen on NOVA as lightning'
so perhaps 'lighning' by Nova is the same episode of the show you saw?

Darn it! I can't find that DVD on their site, nor can I find the original name for the program or airtimes. I'll check amazon for the dvd when I get time.

I did find some cool stuff on laser guided lightning and rocket triggering. NMT seems to be where all the interesting stuff is, but their site is down.

Thanks.

The main research team featured in that episode of NOVA is the one led by Dr.Uman and Dr.Rakov for the University of Florida.
Their website can be found at this link. Link2

The equipment they use is a combination of standard meteorological stuffs and an array of electric field mills. Link2

Not meaning to rain on the parade, but why use rockets? Because it looks cool?
If I'm not much mistaken, some guy a few years back used a kite and a key or somesuch to discover that electrickery nonsense. Wouldn't it make so much more sense to loft a kite attached to a bit of 20AWG?

"Some guy a few years back"... yeah that was Ben Franklin =P

A rocket seems like a good way to pinpoint the cloud... how do you tie a kite to a post and fly it? :P
