Let me go check the exchange rate...
...yep, that's about £240, *way* more money than I can afford to spend.
(Then again, I don't have anywhere approaching 1TB of data to store.)

I don't mean to imply that quality is *necessarily* an issue, just that
it *can* be more of an issue. As you say, it depends who you buy from.
I often buy from Maplin because 1) I don't have to wait for it to be
delivered, 2) their staff actually have a frickin clue, and 3) they
don't argue about returns.
Then again, ebuyer.com are usually very good, so...

Me too - my car has 180 BHP, yet when I drive carefully my record is 960 km
on a single 50 litre tank! To me that is just amazing, a car I had that was
20 years older had only 60 BHP and could do only 400 km on a tank (probably
a bit smaller tank as well though).

I think the biggest improvement is that today, even if you haven't used your
car for 2 weeks and it's -15 degrees outside, you can turn the key and the
engine will fire up perfectly within a second and then idle smoothly. My
dad had a car (actually he still has it) that has no choke at all, not even
a manual one, starting that is a PITA unless you are very good friends with
the accelerator pedal - and it won't idle at all until warmed up fully, so
you need some tricks with your feet when in traffic to stop it stalling!

I wonder how long the "pulse" of radar would need to be - the engine could
charge up a big capacitor to discharge in a roof mounted dish - hmm maybe
not that sounds a bit too much James Bond :-)

then drive it for 400 miles before needing to fill up again.

My dad has had more old bangers than I've had hot dinners, but I've
never seen problems starting the car because of the weather. (Except
when it's actually snowing.)
Then again, in the UK the temperature never, ever, for any reason,

I can't believe anyone who has lots of old bangers has never needed to get
out the WD-40 in wet conditions to start the engine. In cold conditions the
oil just gets thicker, if the engine is a bit "temperamental" then a very
cold morning can make it difficult to start.

Oh, he's had plenty of cars that *never* start properly. But I guess in
the UK it just never gets cold enough to significantly effect things one
way or the other...

Huh? That doesn't sound right. An old strategic option the USSR apparently
had was to detonate a -real- big (50 megaton) thermonuke over the US, but
out in space / low orbit. The idea was to melt all radios and computers,
the entire US telephone network, etc. As far as I know EMP damage is caused
by the massive radio waves generated by a nuclear explosion (besides all
the "hard" gamma radiation, and other nasty stuff besides heat and light).
These induce current in conductors (i. e. they fry microchips).
Radio definitely travels in a vacuum where there is no magnetism - IMO,
magnetism CAN effect radio but just to distort or interfere with it. So I'd
think that a magnetic field will -moderate- or interfere an EMP pulse a
bit, not be the part-cause of it?

Not sure what it is in BHP (oh you continentals!) but my car has a 1595cc
engine with max. output of about 71KW (kilowatts). In city driving I get
about 680km to a tank (40 liter capacity, unleaded, o' course) and on the
freeway it does about 810km on 40 liters. Guess it doesn't compare as
linearly, but the Ford I referred to in my post is a 2995cc V6 (the so
called "Essex big six" - 101.5KW at 5900 rpm) dating from 1969 with a
double-barrel Webber and mechanical ignition. It struggled to do 400 kilos
on a 65 liter tank even when it was new. Yup, he still has it.

I KNOW THAT FEELING! The Ford Cortina I refer to above behaves much like
that too. Once it is running though it is quite ok, but I've also had to do
the "pedal dance" with it once or twice when I cranked it up to take some
trash away. Its got one of those "auto chokes" Ford used to have where you
depress the gas pedal all the way to the floor, firmly, then try to start.
But often its better to pop the hood and set it manually on the side of the
carb before even thinking of cranking it in cold wheather. It also likes
priming - i. e. it is much easier to start if you pump the pedal ten times
or so before trying to start, especially if it was standing for a week or
more.

Maybe not, that's sounds like a good idea! If you can aim and modulate it
right a one-second high intensity burst might do the job on a computerised
injection and ignition system... You'll just have to deal with the lawsuits
and damage claims if you zap somebody's car who is innocent...!
And hope the criminal isn't wise to the deal and driving a mechanically
ignited and carb'ed vintage model. Or a diesel!

Yeh an old CAD program we had here (ported from Unix) worked like that.
You'd navigate using some standard Windows file open dialog box (at least
they managed to use that) then when you chose the file it would give a "File
not found" error! If you didn't remember this then you'd be sat there
thinking WTF why can't it open this file...
