From Discover:
This futuristic method is based on a centuries-old observation that electric fields can do funny things (videos) to flames, making them sputter and even snuffing them out.
The researchers’ early-stage prototype consists of a 600-watt amplifier hooked up to a electric beam-shooting wand, according to their presentation at the American Chemical Society meeting earlier this week. In tests, they were able to quickly zap out flames over a foot high.
I look forward to the day when I can dial 911 and get the ArcAttack guys over to put out the blaze!
