Re: Blowing up the engine

Chris,

The auto mfrs don't even measure the emissions on the highway any more.  
It's so much lower than cold start.  Virtually all of the current work on 
emissions is spent on cold start.

Has anyone considered that a cat converter really doesn't **clean** 
anything.  If you ask a chemist he will tell you.  All it does is convert 
(that's it name) illegal pollutants into legal pollutants.  The only way 
to really cut down on pollution is to burn less.  

I for one am not convinced that all the additional tons of hydrogen
sulphide, and sulphuric acid are more beneficial than the original stuff.

Has anyone noticed that acid rain is a much more serious problem since 
all the fly ash has been removed from the stacks of coal burning 
plants??  Fly ash neutralizes the acid.  

I guess my point is that the interactions are really complex and we don't 
think long enough to understand the implications of what we do.  After 
looking at some prehistoric climate studies it's interesting that for 
most of its' history the earth was seriously colder than it is now.  
Enough to really matter.  The current temps are really just the top of a 
sort of wide spike in the temp record.  I think that is something to 
think about.

Steve
