Catalytic converter radiator

[freebeard]

Just A Car Guy: did you know vehicles radiators can be coated with an ozone reducing catalytic coating? Manganese oxide, a catalyst, not consumed during the conversion of ozone; therefore the catalyst’s lifetime is extensive, usually several years.

as it drives along, it reduces ozone, a component of smog, capturing about 75 percent of ground-level ozone and converts it to ordinary oxygen

The New York Times had an article on it in 2000

in the 1990s, Volvo worked with New Jersey-based catalyst company Engelhard to use the radiator as a sort of "filter" for smog-producing, ground-level ozone that passed through it in a system called PremAir.
....
Volvo's PremAir coating, the representative went on, only added about $50 per car...

One wonders how much it would cost as an aftermarket add-on. Can it be refurbished after 'several years'?

Pretty cool. If an area is windy, it seems to me it would be better to just place them along roadsides, but cars do have the useful property of moving through the air.

Vehicles drafting in convoy would maximize the effect.

Pairs well with ozone generators.
