Wait a minute. Are you saying you are unaware that nearly all fuel

REFERENCE for this?

Apparently you require one to 'prove' that Varta can make a simple 2700mAh > NiMH cell !

I suppose you think Varta are lying ?

Wow.

WOW indeed.

Just buy a Varta 2700mAh NiMH and check it out. On sale now - the battery > you claim *CAN'T BE MADE*
!

Don't be a fool. I'm not doubting 2700 mAh AA NiMH batteries.

You were a few posts back.


No I doubted your assertion that 2700 mAh proved that Honda's figures
were off by a factor of three.


I'm doubting that such batteries have energy densities 3x higher than
accepted figures.

Early NiMH AAs had a capacity of ~ 1000mAh. Which one conforms to 'accepted figures' ?

I tend to think Honda's experience with EVs is to be trusted more than
your gut instincts and poor math skills. haha.. I know that's a
shocker to you, and a blow to your inflated ego. But that's my
position, and you haven't said anything to change it. Though I'm
still talking to you.
..
This whole issue arose from Graham's statement that the figures Honda
quoted in their EV website as being 1/3 the currently accepted figures
for NiMH batteries. Graham said that not me.

I never referenced Honda. You introduced them.

That's right. I pointed to the experience of Honda as a reasonable
expectation. You said you could go 100 miles or so with 160 pounds of
NiMH batteries and I said Honda can go about 100 miles with about 800
pounds of NiMH batteries - and doubted your figures. In response you
said you were better at building cars than Honda and their engineers
didn't know a damn thing about batteries and to prove it you did a
calculation with a AA battery you bought which proved their numbers
were 1/3 the value you got and they were all wet or using old data.

In response I asked you to show me any literature anywhere that touted
a 3 fold increase in the energy density of NiMH -

At that point you launched into a vituperous personal attack of me and
interestingly enough academics and peer reviewed literature. haha..

At that point I marked you off as a self-important nutjob.

But I'm still interested to see what you're going on about... lol

I have no interest whatever in what they have to say on
the matter.

Oh no, I agree, your abilities and experience in building automobiles
far surpases theirs! HAHAHAHAHAHA!

Their work was clearly with older technology batteries.

That's not clear at all. More likely you got your numbers wrong and
they're using the very same batteries - except they're really
engineers who know what they're doing and you're just a guy with a AA
battery and the package it came in doing your maths wrong.

This came from the observation that Honda needs 800 pounds of
batteries and Graham said he can get the same performance out of 160
pounds of the same kind of batteries because a) his auto design is
better than the best Honda can do, and b) he uses more modern
batteries are 3x more energy dense per kg than Honda is able to come
up with.

In response to these bold claims I asked Graham for pointers to any
literature that supports his latter contention. To which he came up
with some figures about AA NiMH batteries- which I found unconvincing
- and still do.

The energy density figures are a fact.

Please point to anything anywhere that says that NiMH is 3x more
energy dense today than it was a few years ago, and prove that Honda
doesn't know what they're doing.
