Re: Who killed the electric car?

I definitely think that manufacturers are looking at pollution/cost of motoring from the wrong direction.

Sure, an electric car has less moving & serviceable parts, but what about the REALLY expensive part - the batteries? At the moment, they are using batteries similar in tech to mobile phones & laptops, and even bearing in mind the short life-span of these products before they are rendered obsolete & thrown away, there is a thriving business in selling replacement batteries...

Tells it's own tale, imo.

The 'range-extender' principle has more viability, yet, I cannot see any practical benefit in making a car heavier, to make it more economical. Why not use the money it costs to add batteries/motor, etc in more exotic materials which would allow conventionally-shaped cars to weigh a fraction of what they currently do? This would either give a car with similar output, sportscar performance with half the fuel consumption (and emissions), or allow for smaller engines to be used, which again would be at no detriment to performance, but would significantly decrease the fuel consumption.

Lighter cars need smaller tyres/brakes/wheels - reducing unsprung mass, again a significant saving.

Cars wouldn't corrode, or need replacing - but that is maybe the 'real' reason.

All the vehicles you can buy have a strong degree of built-in obsolesence, therefore, we keep on buying.

Cynical? Moi?


This job should never be complete - the day I think I've done it all, is the day I resign.
