I have the same experiences with the list, and the same questions.
One poster in particular I have noticed that does not show up on the Yahoo
archives is Sheer.
My solution is to receive the list in "digest" format. Usually one per day,
(about 53K), unless the list is very busy or Bruce is posting newswire items
then maybe two per day.
Then I just scan through those and see the posts I missed.
I also wonder about the status of the Crest archive.
Answers to these questions would be great. :^D

Rudman's first charger used these with a transformer, variac and a bridge.
It worked just fine and still works today.
SCRs produce hash when you are using phase control. If you have a zero
crossing detector or are switching them very slowly, you will never notice.

Hi EVerybody;
Gees! Quiet here. Nothin' in the last few daze.Something must be down for
the holidays, or I'm unsubscribed? Anyhow, if I'm getting through. Happy New
Year, and a great EV year, for you, coming up. Will be the year for new
batteries, more range, speed, lighter cars. Best of all could it be a
turning point for EV's? GM an' Ford bringing back working cars for us?The
American Public? Stay tuned, should be an interesting year.

surprise, the mighty SUV isn't as safe as most folks think, both to
the driver & passengers and to people in other vehicles; only Pickup
trucks are worse.
Granted, this is the proper and scientific manner in which to
examine the data, but when asked why they're driving big SUVs, the
first
words you hear out of every Soccer Mom's mouth is that it's safer
for their children.
Of course, a critical analysis of the study shows that it doesn't
disprove Mom's instinct: the study doesn't examine injury effects,
nor does it examine vehicle occupants other than the driver. The
study does not use a regression approach to control for the vehicle
type of *both* vehicles in any given crash, and the study did not
explicitly control for driver type (although they did make a
preliminary effort to determine whether or not the impact of driver
type was overwhelmingly significant). I think it is also important
to note that the study was published by American Council for an
Energy-Efficient Economy, which bills itself as "a nonprofit
organization dedicated to advancing energy efficiency as a means of
promoting both economic prosperity and environmental protection."
While those may be laudable purposes, they are hardly an unbiased
source for a study of this nature.
This is a good study and provides some useful information, but I
would hesitate to leap to the blanket conclusion that SUVs are
intrinsically more dangerous than smaller cars. Of course, Mom's
instinct that SUV's are safer isn't well-founded, either, and may
very well be untrue. However, this study does not prove her wrong.

While Google-ing to find some past posts, I recently stumbled upon "The
Mail Archive":
http://www.mail-archive.com/ev@listproc.sjsu.edu/maillist.html
I don't think this is a complete or an official archive, but might help
for now?
Happy Christmas.

Looks like the list got a dose of laxative and is working again. Kind of
spooky that it got hosed right after I posted about the archives. Sorry, I
didn't mean to break it....
Thanks for the responses, at least those which have appeared on the Yahoo
archive. Daily digests aren't a good solution for me, I probably don't read
2 out of 20 posts most days, and it's a lot easier to pick which ones to
view in archive format.
Jim; your message about "The Mail Archive" got garbled by Yahoo, apperantly
because of an "@" sign in the address.
( see http://autos.groups.yahoo.com/group/EVList/message/33880 to check out
the damage). Any way to communicate the URL without it getting "sanitized"?
Of course, Yahoo is a poor substitute for a good archive. Anyone know
what's up with Crest? One page I happened upon ~swears~ that their
discussion lists will be functional this week
( http://crest.org/discussiongroups/index.html ). Guess we'll see. You get
what you (don't) pay for these days....

Obviously, a real fuse has been designed by experts and thoroughly
tested, so you KNOW it works. If you build your own, the burden of
testing and risk of failure is on you.

It's not that simple. A fuse is really a resistor, and it "blows" when
that resistor is asked to dissipate more heat than its surroundings
allow.
A naked piece of copper wire in air can dissipate an enormous amount of
power before it fails. This is because copper has a high melting point,
conducts heat well, and at high temperatures air is pretty good at
carrying away heat.
So the first thing they do is pick a metal with a lower melting point.
Second, they stick the fuse element in some kind of package to prevent
it from dissipating heat. Cheap fuses (like car fuses) use plastic, but
this melts and burns and so it unsuitable for high voltage fuses; they
use phenolic, glass, or ceramic.
Third, when a fuse does melt, at anything much higher than 30 volts an
arc forms between the ends. Arcs are fantastically hot. They can
superheat the air, causing high pressure inside the closed space so the
fuse case explodes. They can melt, burn, or vaporize any materials
nearby. The debris from this can itself be conductive, and so sustain
the arc.
So if you feel you must make your own fuse, look at real fuses and copy
them as closely as you can. For example, you can use a piece solder (not
copper) as your fuse element, and put it inside a piece of sleeving
(woven glass, not plastic), and secure the ends on a terminal block (so
the loose ends don't blow apart). Then TEST it to see where it really
blows, and to be sure it won't start a fire or let a live wire get
loose.

After jumping through hoops to prove to non-English
speaking faculty I could speak English, so I could
register for a required English course (what a
school system 'pain'), I decided to use the few days
I had to vent some frustration.
I took off heading down south to verify housing costs
and the job market in those locations.
I voyaged out into the great EV void:
S. Central Valley, Bakersfield, Mojave, etc.
I knew I had re-entered civilization when as I was
cruising the San Bernardino highways, and I saw a
'Electric Vehicle Charging' sign. These are like the
fuel and lodging highway signs for the next exit.
Seeing that EV charging sign on the highway brought
a smile to my face (that felt sooo-gooood).
All along my trip South and back, through Riverside, to
San Diego, and back North through Los Angeles, I saw
those signs. While I did not have time to check each one
out, you know I wanted to know if those EV charging spots
had the universal conductive AVCON charging head that any
EV could use, or an inductive.
Well, I'm back now. My Blazer EV did not get to have
Clare Bell's magic touch (we did not connect to get some
work done), I have a ton-o-email to respond to and
discussion group subscriptions that are pending.

I think though, that people would weigh the damage in Accidents more than
damage vs tree.
I drive fairly conservatively, and do not expect to go careening off the
road into a tree.
However I can not keep some dum dum from swerving and hitting me.
I dont think too many people think of it like nuclear or battleship
proliferation, where you want something bigger or heavier than the next
guy.. just in case you happen to meet up under less than ideal
circumstances.
So now if everyone just drove Excursions..just to be safe, would we really
be any safer?
does anyone know of statistics where they take into account hitting a tree..
or a 'like' vehicle.
instead of just taking raw data where some excursion mows down some guy in a
Geo.
Maybe stats from Korea? where they have vehicle weight limits?

I haven't used a solid state relay on a Russco, but have on variacs and
several transformer based chargers. They worked fine.
Yes, solid state relays can be a little noisy. But that should be
nothing compared to the noise from the Russco or any phase-controlledor
switchmode charger.
My main concern would be that big transformers and variacs draw
tremendous inrush currents. The solid state relay has to be a lot bigger
than you'd expect to handle these peak currents. Don't expect a 25 amp
relay to handle a 20 amp charger -- use at least a 40 amp solid state
relay!
Also, don't forget that solid state relays get hot. They need a big
heatsink and plenty of cooling air.
