Recently I read that air pollution is associated with
deaths
and illness, particularly at the developing world.
Wikipedia says, “nitrogen dioxide is responsible for
23,500
premature UK deaths per annum” So globally that could
be
over a million.
A technology could put automotive style
catalytic
converters indoors very cheaply.
A recycled catalytic converter is about $125-200. So,
noting that the volume of air indoors is far smaller than
the
volume of a continuous stream of exhaust, perhaps
1/100th
the amount of platinum catalyst could be used.
So, for just $1 or $2 the core component of the air
purifier
could be constructed. It could be heated with a
filament,
or perhaps a laser pointer making a high temperature
spot
with a fan blowing air past the catalyst.
Places such as China frequently have indoor particulate
filters now. This could be an added feature. A $5
standalone unit might be possible with mass production.

Before becoming overly concerned about that number, perhaps it would be wise to establish accurately just how many of those individuals your world is better off without ? |

John Donne's assertion that "any man's death diminishes me, because I am involved in mankind. And therefore never send to know for whom the bell tolls; it tolls for thee." is glib and ill-considered. That bell tolling might equally well a cue for a song, specifically "Ding, dong, the witch is dead ! " |

Considering the vast numbers of talent-free worthless gits allowed to wander round unchecked, following careers in journalism, law, or politics, and using up perfectly good oxygen that could be better employed to sustain thieves, drug dealers and child-molesters, a bit of research would yield large dividends. |

Another version of this could work at central HVAC where a
possibly regular sized catalytic converter could remove all
the NOx from whole-building air circulated at office towers. |
|
| |
They could have a sensor at the HVAC to find out how much
NOx there was in the circulating air then energize
appropriately. |

// energize appropriately // |

So for government buildings, could it release Zyklon-B into the air handlers ? |
|
| |
That would be a huge benefit. |
