Here are some facts.

You can get a 1.2V 3.8Ah NiMH cell that weighs 27g.

That's 5.9g / Wh

(note that the EV1 lead battery-- 1,200 lbs--is heavier and holds more
energy than this) 4.5 miles per KWh is typical experience of EV
builders. (that's 150 mpg eqiv)

What on earth are you doing talking about lead-acid batteries ? That technology has
no place in this discussion.

My battery would weigh under 100kg. A tenth of a tonne. Les than a tenth of a US ton.

I said 48 miles range on 15kWh. That's 3.2 kWh per mile. That's because I'm taking a
more conservative approach to my engineering and it's not some 'mini car'. The idea
is to make a genuinely viable typical 'family car' as a hybrid EV, not some daft
'technology demonstrator'.
