Another thing about electric cars

VW do eight years on capacity not dropping below 70%.

Fill a Fairy Liquid bottle with a suitable mixture, stick your hand out of the window and direct it onto the windscreen.

Infinitesimally adjustable speed, but they stopped when you put your foot down when going up a hill.

On my father's 1939 Austin Cambridge the dip switch extinguished the offside light and dipped the nearside with a solenoid moving the reflector.

The Pinto was the classic. Several incidents. There was a notorious cost benefit analysis produce internally by Ford calculating which would cost least, fixing the design or carrying on paying compensation to victims families.

Vauxhall - or rather some of them - had mechanical wipers driven direct from the engine. Rather like a cable rev-counter.

It?s not all about the chemistry, the designs are being improve to increase energy density and reduce charging time.

or passing a lorry generating a ton of spray

Energy density is ABSOLUTELY a function of the chemistry.

And so were screen washers. I remember buying a Paddy Hopkirk screenwasher kit for my first mini which involved drilling holes in the bonnet. Manually operated internally with a pushbutton operated pumper.

And as soon as you crested the brow, they waggled so furiously, the blade would sometimes get ejected :-)

No, my best mate in school was the son of the local Ford dealer. Lots++ of interesting old cars left in the huge yard and field behind the workshop. We would get them going and drive them around the field (age much less than 17). Also a constant procession of new vehicles arriving and being PDI'd in the workshop before moving to the showroom.

How cheap will the annual road tax be though ?.

Chemistry AND cell design.

Do you think the surface area of the electrodes is irrelevant to energy density of a battery?

Tim

In the limit, yes.

But we?re not at the limit yet are we? So clearly at the moment design IS important. So I?m absolutely correct to say that it?s not ALL about the chemistry.

Out of interest, what do you take for your blood pressure? Seems to me you spend a lot of your life being very angry.

Tim

That would be a bit second order - unless the first cells were designed really stupidly.

Yes. We are. See my experience.

Not for energy density.

So I?m absolutely correct to say that it?s not ALL about the

No, you are wrong

No, I dont.

So you would say that there been no progress in lithium cell capacity in the last 5 years? That EV range hasn?t improved dramatically over this time?
