& Clack Talk Cars
by Tom and Ray MagliozziDear Tom and Ray:
My daughters boyfriend
bought a used car from a dealership. The
dealership had a 127-point check to ensure that
its used cars are safe to sell. After driving it
for a month and a half, the battery needed to be
jumped. A friend of mine helped the owner of the
car jump the battery from another vehicle; the
car wouldnt start. So, they removed the
battery and set it on the ground. A while later,
one of the guys bent over the battery and merely
put his hands on the sides of the battery, and it
blew up in his face, causing the loss of his
eyesight in one eye. Why did this battery blow
up? It was not dropped. It was in a Volkswagen
Passat and was an Autobahn battery. - Ana
RAY: Yeesh. Thats awful,
Ana. Its very rare that batteries actually
blow up. But obviously, it does happen
occasionally.
TOM: It has nothing to do with
the battery being on the ground. The reason
batteries explode is that dead or dying batteries
can emit hydrogen gas. And we all know - see
"Hindenburg" - that mixing hydrogen gas
with a spark is a bad idea.
RAY: So, the question, in your
case, is where did the spark come from? Was
anyone around the car smoking? A floating ember
could easily have provided the spark.
TOM: Or was someone wearing
polyester pants? If your friend had built up a
static charge walking around and then touched the
battery, a spark could have jumped from him to
the battery.
RAY: So we dont know what
provided the spark. But something ignited the
outgassing hydrogen and that caused the
explosion.
TOM: But this is a good
reminder that safety glasses really can save your
eyesight. So wear em.

Changes
Dont Faze Renault F-1 Engineer
We spoke recently
with Pat Symonds, executive director of
engineering for the Renault Formula 1 team.
Symonds is one of motorsports top engineers
and executives.
ZYLA: Pat, your
Renault team is leading both the driver and
constructor categories with just a few races left
this year. You have perfected the V-10 Renault
engine and have great drivers. However, 2006 F-1
rules call for V-8 engines only no more
V-10s. Where does this new rule put Renault right
now?
SYMONDS:
Well be fine here at Renault. Its
easy to say, "leave everything alone;
dont fix what isnt broken." But
I wouldnt necessarily say its the
case.
One thing this
team has demonstrated time and time again is our
ability to handle change. We have a culture
within the team that encourages lateral thinking.
It doesnt jump on mistakes. We welcome
change. We think it gives us more ability to
out-think the others.
So, the change to
the V-8? Why not? Its an engineering
challenge, and its what were here
for.
ZYLA: How about
the two-race motor rule? What are your feelings?
SYMONDS: When it
was first proposed that we take engines through
two races, the common Formula 1 reaction was,
"You cant do that. It will never last
two races." I said that there are guys
running around LeMans for 24 hours with race
engines, and I expect to drive my (street) car
for 100,000 miles minimum, so anything can be
done. So, we rose to the challenge, and
weve had fantastic reliability with our
engines. I have had no problems with that.
