Problem statement:  Most vechiles (cars,bus,aircraft,truck) ....provide a Air-conditioning
                    systems or provision a overhead kind of a table top fan!!.

Opportunity and Objective: Deriving from the design of a Hair dryer (a electrical fan
                           with a coil surrounding ...heat the air)

                          ...modified version of hair dryer offers a better opportunity
                             to be used inlieu of current air inlets or regulators being
                             used in the most of these vehicles.

                             The ideal design (for such a utility ...hair dryer) provision
                             to use it as air blower viz. turn off the heating coil ...or
                             turn it on ...when hot air is required  ...with provisions to
                             control the heating as well as quantity of air (viz. usually
                             translating in to ...fan speed).                             

                             Deriving from the above ...a handy battery powered hair-dryer
                             ...that can be used as a fan cum hot air blower i.e. neutral
                             heating of air aswell for out-door activies.
  

                                
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

       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.
