Re: [DML] Electric Conversion Issues

I'm going to ignore Bill-sourced-threads and answer these issues 
directly because I wrote a paper on the subject last year (the 
feasibility of electric cars given current technology) and still find 
the subject fascinating.

In terms of energy, once you store enough battery power to rival a fuel 
powered car for range, the amount of power consumed by a heater becomes 
negligible and you can use use a resistive element much as a hairdryer 
or heat gun does - this is lighter and a lot less hassle than having a 
closed loop cooling system transferring heat from the drive motor(s) 
and/or battery. AC is more complex and still the most thermodyamically 
efficient system is a compression-expansion refrigerator, aka air 
conditioning and run the compressor from an electric motor. Although I 
do like the idea of using the peltier effect, but this while much 
lighter and smaller is dreadful in the efficiency scheme of things.

The bottom line, and the conclusion of my paper is that until battery 
tech comes along in an order of magnitude (ie ten times the capacity for 
the same weight), pure electric cars will never rival fuel powered ones
