     Well, let's think about this. You can probably draw about 10A through 
     the ciggie lighter without burning out the wiring. So at 12v, that's 
     120W. 
     
     Have you noticed how effective a 100W bulb is at heating anything -- 
     not very. You probably need about 500 to 1000W in order to notice any 
     kind of effect from a heater in a car. I don't think your wiring will 
     cope very well with  40 - 80Amps through the ciggie lighter wiring. 
     Also, your alternator/dynamo might have a little problem keeping 
     up.....
     
     Regards,
             Simon
