It's certainly an established fact that electricity can cause fires, but today a group of Harvard scientists presented their research on the use of electricity for fighting fires. In a presentation at the 241st National Meeting & Exposition of the American Chemical Society, Dr. Ludovico Cademartiri told of how they used a unique device to shoot beams of electricity at an open flame over one foot tall. Almost immediately, he said, the flame was extinguished... Apparently, it has been known for over 200 years that electricity affects fire – it can cause flames to change in character, or even stop burning altogether.
It turns out that soot particles within flames can easily become charged, and therefore can cause flames to lose stability when the local electrical fields are altered.
The Harvard device consists of a 600-watt amplifier hooked up to a wand-like probe, which is what delivers the electrical beams. The researchers believe that a much lower-powered amplifier should deliver similar results, which could allow the system to be worn as a backpack, by firefighters. It could also be mounted on ceilings, like current sprinkler systems, or be remotely-controlled. (more)Bill, don't cross the beams. ~Kevin
