Good point in fact! But we are not talking about a thermodynamical process for conversion of chemical energy to mechanical energy. We are talking about a more efficent mechanical to electrical energy cycle. That means we are in the realm of electro mechanical conversions which tend to be three times more efficient.jddh1 wrote:And the braking energy does not need to be converted? If you design a motor that does not convert energy at all, you will be pretty rich I think.WhiteBlue wrote:Braking energy is pure mechanical energy which is the most valuable and not chemically stored energy which must always be converted to be used in a race car.
And there is another aspect. The weight of the KERS machinery can be taken out of the ballast if there were agreement to use a more fuel efficient technology. Pretty much all cars had 30-40 kg of ballast. If KERS was mandatory there was never an issue of any team being disadvantaged.
I do not see absolute performance as a crucial issue as long as F1 is the pinnacle of road racing open wheel performance. If loosing performance from ballst ever was an issue you could easily solve this by allowing 500 rpm more and equalizing that performnace loss while at the same time creating interest in reliability stakes.
