'[TECH]Fire fighting using electrical impulses?'

A report by the American Chemical Society at their March meeting, was on
revisiting an obsevation made 200 years ago that fire reacted to electrical
waves in the vicinity .

"Scientists today described a discovery that could underpin a new genre of
fire-fighting devices, including sprinkler systems that suppress fires not
with water, but with zaps of electric current, without soaking and
irreparably damaging the contents of a home, business, or other structure.
Reporting at the 241st National Meeting & Exposition of the American
Chemical Society (ACS), Ludovico Cademartiri, Ph.D., and his colleagues in
the group of George M. Whitesides, Ph.D., at Harvard University, picked up
on a 200-year-old observation that electricity can affect the shape of
flames, making flames bend, twist, turn, flicker, and even snuffing them
out. However, precious little research had been done over the years on the
phenomenon.



Fighting out of control fires could become faster and
more eco-friendly with an unusual technique that
snuffs out flames using blasts of electrical waves.

“Controlling fires is an enormously difficult challenge,” said Cademartiri,
who reported on the research. “Our research has shown that by applying
large electric fields we can suppress flames very rapidly. We’re very
excited about the results of this relatively unexplored area of research.”

I'm still not convinced wandering around with a 600W amplifier strapped to
your back does much other than impair your hearing.

"Sounds like fun - but these people don't seem to have heard of EMP,
or considered it's lesser cousins.

EMP extraordinaire at 900 miles.

For an only vaguely related education that may recall  more recent events, try:
