#502: Smoke deflector
Despite the increasing restrictions placed on where people are allowed to smoke, I still frequently find myself surrounded by toxin-laden exhalations (eg when walking past the entrance of any office building).
Today’s invention is a way to limit the extent to which passive smoking is still inflicted on people.
The guts of several domestic smoke detectors would be extracted and attached to eg a waist belt. These would be capable of detecting even small quantities of smoke and their differential concentration readings used by a belt-borne pda to control a number of small fans, also carried on the belt. The nearer the smoke source, the harder would the fans be driven; resulting in active stench suppression.
It might also convey the message that standing ouside smoking is still not a healthy thing to do.
