Use a hand throttle like a motorcycle? Put the throttle inductor
somewhere else, and cable operate it? Leave the charger home and use the
space for a battery?

What about somewhere external to the body? Use a couple as the front
bumper? Rear bumper? In a trailer?
Could you use a couple as your "briefcase" Haul them in to work, charge
them, and bring them out when you go home (in a wheeled suitcase)? Use
them with a step-up DC/Dc to "charge the pack as a whole as you drive
home?

Yes, this can work. Acrylic plastic fiber is fairly cheap and can carry
the light for 10's of feet or so before the light is too dim to use.
Hobby stores, or places like Edmund Scientific or American Science and
Surplus sell it.

They are also actively solicting more new products... any EV's out there
close enough to ready if could pre-sell enough to make a production run
feasable? Maybe even a high-end conversion kit?

So he's got a go-kart with an AC drive system? On alternator motors?
Just to clarify, you're talking about the alternator, and not the
starter, right?
Odd, and very interesting!

Do you (or does anyone else) have a list of exactly which motors are

the NiMh pack came from an Insight. That seems like a pretty pricey

Why not see if a buyer can be found (on e-bay, perhaps?), and use the
money to build a real go-kart?
Actually, I picked this pack up off eBay! :-)
Sure, it was a little expensive ($500), but I've just got it sitting
around now. I thought that I should probably put it to some use before
it just sits there and rots away.

Geez - I haven't had physics homework in years. In other words I'm
rusty, but I'm sure any mistakes will be gently corrected:
In metric, you start with ~450 - 680 kg of wood, at a height of ~60 m.
So have 27,000 - 41,000 J of potential energy (mass x vertical
distance), or about 7 to 11 Whr of energy (1 KWH = 3800000 J)(yes, I had
to look that up).
I'd doubt that 10 Watt-hours would even overcome losses. :-(
Maybe if you bring down the entire seasons worth of wood at once...
And now back to my battery box homework, which is for credit. heh.

Yup, that's the one. I went in to my local ASAS today and checked it
out in person. It certainly looks like it can handle the job. I just
don't know what to do with the end of the shaft that I don't use. I
don't want it hanging out just spinning, it could be dangerous. Maybe
I'll put a cover over it or something.

Hello to All,

I went to a local Portland electrical supply house 'Platt Electric' and ordered the
chassis mount recessed flange type L6-30 male twist lock...this is the one I wrote
about
in my post 'What are the Odds?' about how this electrical connector slid right into my
30
year old Datsun's gas filler pipe hole and its perimeter screw holes all lined up
perfectly with the car's three perimeter screw holes meant for the gas filler pipe
flange.
Platt wanted to hit me full retail on this item at $36, but I was able to use a good
EVer
friend's business account and got it for a much more reasonable $23. You probably won't
find this specialty connector at anything other than an electrical supply house, the
kind
that sells wholesale to electrical contractors and such.
Both the male and female 'cord end' L6-30 twist locks can be found at either Home
Depot or
Low's home improvement type stores, because these connectors are quite common, usually
referred to as 'generator connectors' since they're often used on the 5kw-10kw sized
gas
generators. Home Depot handles the 'Leviton' brand...very high quality but a lot
higher
retail price than other brands, but they want a king's ransom for the L6-30 female at
$32...yikes! At Roy LeMeur's suggestion, I took a look at Lows. They offer the very
high
quality 'Eagle' brand and their L6-30 female is just $19, with the male L6-30 at just
$17.
For my multiple EV setup here, I needed to buy quite a few of the female ends, and
while
at the sale counter, after I had pointed out to the sales person that they were
charging
me too little at $17 for the female end (that was actually the male end price), they
argued with me that 'they knew their prices' and insisted I was wrong, so what the
heck, I
bought a couple more than I had planned on getting!

Hello to All,
Ye-a-h.....It seems that every once in a while, I revert back to a more primitive brain
function, back into that dark and murky Plasma Boy thing I'm known for, and in spite of
all that I've learned about EV electrical safety and caution from all of my
'adventures',
it just sometimes, somehow, all goes out the window!
I was inside the Wayland EV race car tow rig, my funky but oh so dependable '89 Ford
Aerostar van, doing a bit of battery maintenance and testing of the dump charge pack,
17
Optima YTs in series for a 204V pack. I was using one of my favorite quickie load
tester
devices, a 7 inch round, 300 watt aircraft landing light, a beefy sealed beam light
that
has a 50 amp initial surge that quickly ramps down to about a 25 amps of steady
current draw.
I've got a few of them around that are set up with nice 8 gauge wires and 50 amp
alligator
clips that allow the leads of a DVM to be inserted, so that clipped to a 12V battery,
I
can watch the battery sag.
I had been going around to each of the 17 batteries, clipping on the ACL and timing the
battery's discharge and charting the beginning and ending voltages. I was at the end of
the string close to the van's open side sliding door, where the beginning and ending
batteries are, and where the 1/0 gauge leads go to the 350 amp Anderson quick
disconnect,
when I had a major brain fart! For some unexplained reason, I had left one of the
ACL's alligator clips still connected to the negative terminal of battery #1, and then
I
simply and calmly reached over to battery #17 and clipped-on the other alligator to its
positive terminal.....BOOM!!!!!!FLASH!!!!!!ZORCHHHH! (yes, all simultaneously). Talk
about a major flash bulb effect, both from the ACL lit up at 17 times it rated voltage,
and from the intense arc that melted off half the alligator clip! There was a heavy
chest
impacting concussion inside the van that would put all of the combined Wayland
subwoofers
to shame, that hurt my body and made my ears ring for about half and hour later, as the
thick convex glass lens of the ACL was cleanly blown off and it shot across the van
like
some kind of cannon load, striking the van wall and cracking into two halves! To add to
the amusement factor, the reflector side of the ACL flew out of my hands and landed
upside
down onto a pile of paper towels I had been wiping the batteries with, and with 204 DC
volts applied, the thick wire standoffs that used to support the lamp's robust tungsten
filament, were now bridged by a bright electric arc (my version of a carbon arc lamp)
which instantly caught them on fire, which spread to a large bath towel that was also
in the
van. So, there I was, ears ringing, blown back against the van wall in a kind of
stunned
state, with my eyes still seeing a big spot, with nearby things on fire!
I grabbed the other alligator lead and pulled it loose to break the arc (the other one
was
welded onto the battery post with bits of molten lead here and there), lifted the
reflector up off the burning stuff, and then snuffed out the flames with the rest of
the
towel...whew!
Anyway, it seems my alter ego is alive and well :-)
See Ya......John 'Plasma Boy' Wayland
Anyone care to analyze how a sealed beam light can turn into a cannon?

Matt,
If it has a commutator and brushes (you can see this through
vent holes) it is universal. If you are still concerned, connect
it to your car battery and it will run slow (assuming it is a 120Vac
universal motor).

It wasn't that I didn't like the regen I just didn't like that It kept
braking but zapi fixed that for me the last time " we don't repair that
model as its out of date" Fixed right over the phone (joke) . Solectria is
AC? "Hills" I have heard of those things . The most I ever saw on the
meter was .1 ah go back in to the bats . Do you think that the AC regen
would hold up if you towed the car and had it on . could do some long dis
by getting a tow and charge and same time. You have an escort , I had a
lynx (almost the same) and it was the best EV I ever had, gone but not
forgotten
