Today’s invention is a fire safety device, to be used in confined spaces where smoke inhalation can be very dangerous.
It takes the form of a ‘cooker hood’ (green) attached to a powerful fan (pink). The hood is attached to the (low) ceiling on a rail so that it can be positioned nearer a fire. This draws in a large percentage of any smoke being generated and passes it over a 3-way catalytic converter.
The proximity to the flames activates the catalyst’s chemicals and their effect is to strip out many of the most noxious pollutants.
The hood might also carry a conventional extinguisher. It could, in addition, allow the water produced by the catalysis process to fall onto the fire.
This provides people with more time to escape.
