    I've been interested in these = off and on.  The argument against them has always been that = there's so much airflow through the cowl, that Halon might not be = effective.  We still have Halon in some of the MRI suites, but = those systems are automated to close doors, and turn off any = ventilation systems when they're activated.  I know these types of = systems are used in race cars, but I imagine they're usually activated = after the car as come to a halt. 

     
    I'd be interested to hear = some thoughts on this.
