Problem Statement: All kinds of vechicles 
                    (2/4/mass transportation systems ...railway diesel /petrol based)
                   emitt gasesous emissions ...which consist of carbon black as the
                   a major proposition 

Opportunity : Given that carbon black is a resuable commodity,

              it offers good opportunity to harvest the gaseous emissions from
              vehicles.


              Carborator ideally offers a good option for the above ...or
              using a deep freezer ...that immediately solidifies the gaseous
              particles ....should also offer a viable option where applicable.


Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
