The fireman of the future won't be a burly man holding a big hose, if Harvard scientists succeed with their research in this field. Instead, it'll be a burly man with an electrified stick.
Their work has focused on the 200-year-old idea that sending pulses of electrically charged air at the fire can actually snuff it out. With any luck, it would be make fighting fires more affordable, and also make firefighters less reliant on water as a means to an end. Plus, it'd mean there's a greater chance of saving what's inside the house - and the foundations itself - from the damage water often creates. [Eureka via Popsci]
