I can assure you there are not....

I know, you have told me before

but you are just a random person on the internet so why should I
attribute more weight to you than to all the other "random" persons on
the internet who disagree with you.

Some of whom are actually academic physicists (even if I have never
heard of them) and some people with a very real interest in it
actually being right.

I have no personal opinion on who is right, but you really do not have
the visibility for me to believe that it is you.

Especially when, without these two orders of magnitude improvement,
electric cars for the masses, that automotive companies are investing
billion in, are never going to happen.

Tim, I'll be amazed if you can find any scientist who thinks you can
get two orders of magnitude more storage in a chemical battery. The
limits are down the the reaction energy of the elements involved, and
these are well known.

So why aren't these scientists explaining to politicians that their
aspiration of 100% electric cars/vans/lorries is unachievable.

To get mass take up of electric cars you have to have a range of 350
miles (in real use), a residual value after 5 years (so the initial
battery needs to be useful for 10) with base models (still with that 350
range) selling for under 15 grand (today's money).

At least 3 times a year, I have a requirement for a 400 mile, one day,
journey - each way.

At the moment we have electric cars that don't have the range for main
family cars and that are too expensive for second cars.

If we are never going to break out of that circle the sales for electric
cars are never going to exceed 10%.

And yet, worldwide, politicians ARE expectation to cast the IC engine to
history by 2025.

And I won't even start on how they expect people to charge up at home
with planning rules that allow developers to build hundreds of houses on
an estate with only communal parking.

One space per household round here. Even if the family has 2 cars -
needed
when public transport doesn't run at weekends and not after 5pm (or before
10am)

as there is round here

but it isn't the same space, and if you aren't one of the first 3 people
back home the next free space isn't always convenient.

So it's impossible to put in a charge point that is fed from my electricity
meter, which means that it will have to be commercially operated and charged
for
