This is sort of a follow-up to the S.A.M.E. alert project I was attempting last summer. Back in 2002 I read about lightning detection devices being used in national parks and college campuses to warn of dangerous conditions. Some were even advertised as being accurate enough to antipate individual strikes and activate a local alarm.
Spring is coming so naturally my interest in all this was revived. With the variety of devices that are able to measure electric fields (MOS comes to mind), it doesn't seem unreasonable to attempt a device that could detect a dangerous field. I once heard of something called an electron mill that used a spinning disc to accumulate a measureable charge in a variety of condidtions. Unfortuananly googling for it now yields few results which makes me suspect it really went by a different name.
Anyway, my question is: are there any devices or projects out there that would have this capability? And what types of lightning warning methods are out there in general? If someone could make a low-cost system, they'd be swimming in $$$.
