Default 'Steam' powered cars...

Doctor Drivel ) gurgled happily, sounding much like
they were saying :

The thread that's mainly been
solid facts against you


The thread has been nothing of the sort. From fools like you who
initially said batteries could only go a few miles it is now proven
battery cars can get 200-300 miles.


At a pootle. At speed, the range plummets.

From people like you saying it
takes all day to charge, it now is proven it takes a few minutes and
brake re-gen too.


Umm, no, it hasn't.

You've shown that itty bitty mobile phone batteries can be quickly
recharged, but the very link you gave states that they're nowhere near good
enough at energy density for vehicular applications.

BTW, Mitsubishi have new all
electric range in a few years time with motor in the hub.


Indeed.

That'd be derived from this autumn's Evo MIEV concept, would it? The one
with 2300Ah of batteries, which all-up weighs 100kg more than the petrol
equivalent despite the very clever lightweight hub motors? And an *optimum*
range of 150 miles?

And at real world speeds?

Now, lemme think...

2300Ah batteries at 15v.
4 x 50Kw motors, so 200Kw.

I wonder how long those batteries can be expected to last at full power?

Oh, look, top speed's not much over 100mph, so they will be working fairly
hard at motorway speed, won't they?

I tell you what, DrD, you're the electrickery guru - you do the maths...
