Have you considered using the front end from an S-3 Malibu? A little
different look, and a few aftermarket pieces are available.

Hello James,
To make the build easy in using aftermarket fiber carbon parts that will
fit the year vehicle you choose. Look at a lot of catalogs that supply
these items for a certain range of vehicles.
My problem with my EV which is a 1977 El Camino, is that they skip the
years from 1973 to 1977 for replacing a lot of the panels with these
panels. If I have chosen a 1978 year, I could have replace the front with
a fiber air dam and bumper, hood, front and rear fenders, hood, doors,
rear gate, and hatchback and rear fiber bumper.
The weight of the vehicle alone in stock form is 4400 lbs would have been
reduce to 2600 lbs. Replacing the frame with a chrome molly space frame
and install aluminum inner panels, the weight of one of these El Caminos
was down to 1300 lbs with a engine, which was built as a funny car by
parts from the El Camino Store.
Another way to go is to build the body out of magnesium steel aircraft
type of panels or something like a alclad alloy. To form these panels
will take a english forming wheels, rollers, and tig welders.
You can form a flat piece of metal to a round curve shape by cutting out a
wedge section out of the metal and than pushing that edges of the cutout
wedge together and weld that joint together. This will form a curve
section in any direction you want. This is a Italian method in forming a
custom made panels.
For maintenance ease, I would hinge the whole front and rear back. Could
make a mid motor assembly where the motor is connected to a transaxle and
a independent suspension system. There could be no wheel cut outs in the
side panels, because hinging the sections allows you access to the wheels.
One thing I used in my EV is a Air Ride Technologies suspension system and
Mark Williams axle systems which handles the added weight and height of
the car.

Subject: Full size pickup
List,
I would like to build a full size pickup truck. From the frame up and
build
it right. I am going to strip an older full size truck down to the frame.
And begin there. I want it to make a statement. I am going to lower it
and
replace most of the bodywork with fiberglass components to lower the
weight.
I want to get some ideas from the group on what they would recommend. I
would like to be able to take it to the track, shows, and schools to show
what can be done.
I am open to any and all suggestions.
Regards,
James Mckethen

Great pix. Some of the best I've seen of a hydro plant.
Those ARE little generators. 24MW is about half what it requires to
run a nuclear (or large coal) plant's Balance of Plant equipment -
pumps, fans, lights, etc.
Just to put things in perspective, that entire hall of generators
makes 9*24= 216MW. A single nuclear unit generates from 800 to
1400MW. A two unit plant can make up to 2800MW. Browns Ferry, a 3
unit plant, makes 3600MW.

So the new S10 truck doesn't have a heater anymore. Not a big loss; the
heat unit is a small 2kw water heater that is kinda small actually. I
want instant heat.
Which brings up a question: Bosch and some other companies make flash
water heaters for houses. In the category of 120amps at 240 volts of
heating power. Has anyone thought about connecting one of those to a 300
volt pack for really quick water heating? Even backing it down to 40amps
(one set of heaters) would put 12,000 watts of warmth in the water pipes.

I was never able to get a camera in BFNP. I have some others such as
TMI but I never too the time to take those grand overview photos that
show the entire turbine deck or whatnot. Usually photos of whatever I
was working on.
Look here for some excellent photos of various plants.
http://www.nukeworker.com/pictures/
I spent a couple of days going through those photos awhile back. I
recall some good photos of an alternator overhaul but I can't recall
which plant.
One note about ratings. Much documentation contains nominal ratings.
These were extremely conservative and it was always assumed that the
power would be boosted at least 20% or so after commissioning and
commercialization.
Over the last decade there has been a MAJOR effort by the industry to
uprate nuclear plants. It's just too hard to site a new plant so
upgrades are the name of the game. The alternators were always
under-rated and just loafed along. The issue was power density
(kilowatts per linear inch) of the fuel rods. Mainly the result of
operating experience, the permissible density has been upped.
Sometimes when steam generators are replaced, larger ones are
installed as part of the uprating.
If you look at the literature, Browns Ferry will be rated nominally
900MWe per unit if I recall correctly. These have been uprated to
1200MWe per unit, three units. Sequoyah NP near Chattanooga was
nominally a 1200MWe per unit plant. If my memory from my last
conversation with an engineer friend there, the current rating is
1400MWe per unit, two units.
As far as size goes, there is just no way to comprehend just how big
these plants are until you visit one. I spent most of my career in
one plant or another and I still have a hard time believing just how
big some things are.
I have some scanned photos that I can put up on my web site when I get
a round tuit. Nothing very remarkable but a few are interesting.
Remind me if I forget.
John

Interesting!
I wonder why they put batteries in each vehicle? Given that it operates
on an elevated track, I would have thought a third rail would have made
more sense for powering it.

A battery trailer is a viable way to extend range. Hitch it up when you
need more, leave it at home when you don't. It's also available to help out
if you, uh, overestimate your range. The only real disadvantage is that it
makes the car a bit more awkward to handle, but I think there are double-
link hitches that can help with that. Someone else here may know more about
such hitches.
A battery trailer worked nicely for Team New England in two (maybe more)
Tour de Sol events. IIRC, they placed first at least one year (2001?
2002?).
Regrettably Olaf Bleck's website with pictures of it has vanished. Here's a
rather small black and white pic from NESEA (look quickly before they take
it down; many of their other old pics are now dead links) :

Hi Mark, these are what I use in my New Beetle. I have about 10 months on
them, with no issues.
Gel cells do not deliver as much current as AGMs or wet cells, but last very
long and have been known to hold their cell balance better than other
technologies.
These are also the battery that is used in the Solectria cars. Check with
the Solectria yahoo group if you would like more information.

Sure; lots of them are out there. My first thought would be to get a big
surplus industrial EV charger. These monsters are basically just a big
transformer and rectifier in a box with some simple controls. Most are
built for lower voltages like 48v or 72v, but could be rewired for 2x
this quite easily. Heavy, though.
You could also build a bigger version of a bad boy or variac charger.
These a not isolated, so you need a lot more care to avoid shock hazards
and ground faults.
A motor-generator is another possibility. If I were going to do this,
I'd use the EV's own motor as the generator, and just add an
appropriately sized AC motor for the charge rate you want. You'd need to
have your EV set up so you can do regen, but then it's available while
driving as well. The AC motor could also be used as an AC generator, so
your EV could easily provide near-perfect sinewave power during power
blackouts.
Finally, a dump pack in the garage is an easy approach. That could give
you a very fast bulk charge, faster than a home's AC service would
otherwise have allowed.

Steve,
Here is some data:
I drove the Voltbuggy 45 miles round trip to work for a couple years.
(23) 6v t125s, in summer I could do it with a couple miles to spare (avg
temp 90F) In the winter 1/2 mile short normal driving (had to conserve in
winter - avg temp 50F). The pack was strung for 138v used on GE 90 v
motor. The pack weight was 1556lb the total vehicle wt 2930lb. P/W
(Power wt ratio or batt wt/total wt) was 53%. This was a minimum set up
for 45 miles, lots of stop and go at the time, no regen.
I would figure you need (23) if your P/W is the same, since it is probably
less, and you dont have regen you need (25)T125s.
Just a WAG Good Luck,
Jimmy

You can series and parallel power supplies to get more voltage or
current. It's straightforward in principle, and fairly easy with simple
"dumb" supplies.
But things can get entertaining if the supplies are "smart", i.e. have
regulated outputs. Then you can have problems getting them to
synchronize and agree on what they are doing.
You have to think about what will happen if one shuts off and the other
keeps running. Will the "on" one force current to keep flowing through
the "off" one? If so, this can reverse the polarity of the "off" one's
output, and blow its output capacitors or other circuitry.
When two supplies are independently trying to regulate voltage or
current, they can get into "fights" with each other. The resulting
voltage can become unstable or oscillate.
It's usually simpler to use each supply to charge half the battery
string independently. But if you do, provide some test mechanism to
insure that you will know if one quits and the other keeps working;
otherwise you could try to drive off in the morning with half your pack
uncharged!

Oh, one little nuke that you can almost wrap your arms around :-)
Actual numbers are still classified (one of the worst-kept secrets
around) but I can say that Tom Clancy made me shake my head, wondering
"how the hell did he get that info?" One little tidbit that is in
open literature. A Seawolf class fast attach sub can do a battle
start (go from shutdown to full power) in "under 15 seconds".

That'd be a good theme song for WZ. Rig it up so the first chords hit
when he nails the throttle! Hmmm, a few check valves and nozzles and
that stereo system could probably generate thrust.

Hello Dave,
The front nose on the EV now which is a EL Camino call Transformer I is
custom built by Creative Industrials in Detroit. To see this nose section,
just type in your search engine:
Roland Wiench Transformer I
You will get to a site call Second Owner. You will get to a page with a
Mars II EV and just page down and you will see a white EV call Transformer
I.
There is a upgrade that I will get in the future for this EV that will have
fuel cells, supercapacitors, and a new set of cobalt batteries for it.

David, and everyone else too :-)
Last month I posted this following thread on some C&D AGM-25 -48V Telco
Rectifiers with automatic float and equalize. They are modular and come
with 2 (out of 3 possible) 7.5A modules. Last I checked we still have 34 of
them. He want's $100 a piece plus shipping if you want them all. As I said
in my previous post I don't have the funds or space to take them all.
However the warehouse manager said he'd let me deal them off 1 at a time if
I pulled them and shipped them myself from the warehouse. So, if you just
want 1 or 2, for $150 each plus the shipping from Anchorage AK (zip 99503)
I'll pay the $100 to our warehouse and pull and ship the thing to you.
Shipping can be by the carrier of your choice.
Since these are all packed new in the box with only 2 modules (for 15 amps
capacity), if you wanted the full 22.5 amp capacity with a 3rd module, you'd
have to buy two boxes. $150 for a chassis and 2 modules is much cheaper
than even a single refurbished module.
My original post follows, as well as this link to the specs:

Subject: C&D AGM-25 -48V dc Rectifiers Cheap
Arcin' deal on some C&D AGM-25 -48VDC Rectifiers. The the warehouse manager
for the communications company I work for has been buggin' me to help get
rid of old junk we do not use anymore and he's down to throwing stuff away.
Last year he sent truck loads of older C&D 60A -48V rectifiers to the dump
that were deinstalled from all our older satellite earth stations. What he
didn't tell me though is that he also had 54 new in the box C&D
AGM-25 -48VDC modular rectifiers. He didn't throw them away because they
were new in the box. He figured he'd sell them to PICS Telcom or other
salvage that re-sells recovered telco equipment. They told him for the
price of shipping from Anchorage it wasn't worth taking them. (I'm not so
sure I believe that) He's been stewing for the year because he can't sell
them on e-bay because of a company policy. He can however sell them to
anyone off the street. Rather than sell them individually 1 or 2 at a time
he's looking to unload them in bulk for. I've already taken 6 for myself.
I worked the deal for a Telco small out in the bush to buy 9 of them so
there are 39 left. I forgot to mention why we aren't using them. Before I
came to work here two of our small earth stations blew up because they
didn't have H2 sensors in the battery compartment. They were just about to
put these into 50 sites when this happened and realized that the newly
required H2 sensors would not interface with the disconnects. So they've
been on our shelves since 1998.
The chassis' are C&D P/N 110-4025L-3A ( the -3A stands for List 3 for those
looking up Specs) AGM 25 Full Feature Power Plant, -48V, up to 22.5 AMP,
includes terminal block for load connections, battery connections, RFA alarm
output, control inputs for HVSD, includes 8 GMT fuse positions load and
battery shunts, tests jacks for plant voltage and current, microprocessor
controller, low voltage disconnect in load leg, and battery temperature
compensation. (1 ambient and 2 battery sensors)
Each chassis takes three but these shipped with two each 7.5Amp rectifier
modules p/n 100-7507-48XT HFM48AC7.5 rectifier 48V, 7.5 AMP (120/208/240
VAC Only).
Fully populated these will put out 22.5A @ -60VDC.
A manual and original manufacturer Test Data Sheets are included in the
boxes.
There's currently 3 for sale on E-Bay $750 for the chassis and $250 for each
modules. You can check the specs listed there or also view them at
http://www.battery-usa.com/C&D_Tech_Powercom_AGM25.htm
He's told me anyone wanting the whole lot can have them at $250 for each box
containing 1 Chassis and 2 Modules.

Subject: go-kart charging
Last week I finally got the chance to teach my daughter how to drive
"her" go-kart ("surplus power" from the evalbum). It's been a while
since we've lived someplace we can actually drive it.
Our neighbor's kid, who constantly harrasses anyone on bicycles by
buzzing around them on his 4-wheeler, was annoyed he couldn't catch it!
It's not too quick off the line, but it is, as one person who
commented after I put it on the photo album put it, "scary fast!" I
need to add a chain tensioner, as the chain is as tight as I can get it
by hand, but is still loose enough to jerk and occasionally come off.
It doesn't help that the drive sprocket is almost as big a round as the
wheel.
Anyway, I'm reluctant to spend the huge amount that it seems like a 48V
charger costs, and so I wind up charging the batteries 1 at a time,
which takes a while.
Any ideas for an inexpensive 48V charger? I currently have 2 12V
chargers. One is "well behaved" (charges at up to 10A, then holds at
14.5V) and the other is as stupid as they come (I've seen it get up to
16V). Currently I bulk charge with the stupid charger since the other
one rarely gets even close to it's rated current, and usually charges
at less than 5A.
The batteries are surplus Hawker Oddesey 40 Ahr AGM's (The controller
is surplus, too - hence the kart's nickname). I also have a Hawker
G13EP as an "Aux" battery to run the contactor (and lights that I plan
to add).

Chris,
My re-converted US Electricar had its water heater removed
(no big loss, it was inadequate anyway as has been discussed
on this list before) so when I have time and a good lead on
a ceramic heater, then I'll open the dash (instead of fiddling with
the old water heater core) and put the ceramic heater in place
of the old heater core.
Why waste so much power heating water if you can get instant
heat from only 1-2kW in a ceramic heater?
40Amp means that you are removing about 1/3 of your range!

Subject: Really big heaters...
So the new S10 truck doesn't have a heater anymore. Not a big loss; the
heat unit is a small 2kw water heater that is kinda small actually. I
want instant heat.
Which brings up a question: Bosch and some other companies make flash
water heaters for houses. In the category of 120amps at 240 volts of
heating power. Has anyone thought about connecting one of those to a 300
volt pack for really quick water heating? Even backing it down to 40amps
(one set of heaters) would put 12,000 watts of warmth in the water pipes.

Hello Dave,
The front nose on the EV now which is a EL Camino call Transformer I is
custom built by Creative Industrials in Detroit. To see this nose
section, just type in your search engine:
Roland Wiench Transformer I
You will get to a site call Second Owner. You will get to a page with a
Mars II EV and just page down and you will see a white EV call Transformer
I.
There is a upgrade that I will get in the future for this EV that will
have fuel cells, supercapacitors, and a new set of cobalt batteries for
it.

Have you considered using the front end from an S-3 Malibu? A little

IGBT is the abbreviation for "Insulated Gate Bipolar Transistor."
It is a less expensive, more lossy, higher voltage and slower switching
relative of the MOSFET.
The performance gap is closing, therefore there is less performance
difference now than in the past.

Personally I don't think a full size truck is a good EV conversion
candidate. However, my opinion is irrelevant.
I think you should take a look at the fiberglass components that are
available and how much they weigh. You might be surprised to find out
that they usually weigh as much as, or in some cases more than, steel
does.
Yes they make lightweight flimsy parts, but these are generally intended
for racing and are not very durable.
The major exception would be the bed. FIberglass beds that are as strong
as the steel ones weigh a lot. However, since you want to convert a
truck for the looks and not the utility, you might be able to get away
with a light weight bed that isn't actually useful for hualing anything.
If I was building a truck for looks, then I'd just go with a lightweight
bed. Replacing the rest of the parts (fender, hood, etc.) isn't worth the
effort. Even if you used the light weight flimsy parts, the weight
savings would be pretty minimal compared to the total weight of the truck.
Another thing to consider would be to really start from scratch and build
your own light weight space frame and use lighter weight components
(axles, transmission, suspension, etc.) from a smaller truck, say
something like an S10. Aside from the significant weight savings, you
could then use commonly available parts for converting the smaller trucks;
transmission adapter plates for example.
Add a light weight bed and use an existing cab from a full size truck
(strip out all the useless weight like sound deadening material, etc.) and
voila'.
Good luck.
