Oh what aobout Fun???
Most of us do it for the fun...
Hey Goldie Could use some seat covers...
Some bondo... and other things that Rich Racers have.
Money is NOT what we do it for.
Win?? it's been years since Goldie held a record of any sort.
It's fun Racing with the Boys.
It's not ego... It's mostly fun with some friends Showing what we can do
with out Gasoline.
The power, Range and charging and conversion costs.. Oh that my day job.
That's what allows me to play on the strip.

Not to split hairs (!), but in CA, the HOV (car pool) lane is separated
from the other lanes by two double-yellow lines, usually with about 18
to 36 inches between the sets of doubles. This is practically another
"lane" for a motorcycle, and indeed, you'll see motorcycles in this lane
all the time, continuously for miles, including CHP. I've asked CHP
about this, and they say that riding between the lines like this is
legal. It's illegal to _cross_ these lines to move from the HOV to a
standard lane, or vice-versa; this is an HOV lane violation, and a car
would also be ticketed for crossing these lines. On a bike, you can
move between the lines, and back to your original lane.
If this isn't considered being on the centerline (as the two double
yellow are considered the divider between lanes), I'm not sure what is.

I have to agree with GW. It's all about what you are accustomed to. In the
rest of the world lane splitting is a common occurrence. Take the
peripherique in Paris for example. In Paris as in many other European
cities, a huge number of people (I don't know the percentage but is high)
ride scooters and bikes. Scooters ride in between the lanes of cars. It's an
everyday thing. No one gets startled, no one except maybe a startled
American tourist yells at them or honks their horn. In fact there are as
many scooters as cars, so it's probably futile anyway - akin to a herd of
Antelope running along a herd of Buffalo. They run together without flipping
each other off. Sure the occasional antelope turn into mush, but in general
they coexist. Why cant we? Answer: Because we in America have personal space
issues. We have expectations that people will "give us our space", whether
it be in a car or walking in the mall. When we don't get it, we get
agitated. Motorcycles and smaller vehicles fill the space because they have
can. Drive safer, the roads are only going to get fuller.

Jody:
Another option to modifying the unibody/frame is using
engine/transmission mounts from the 4-cylinder version of the car,
rather than the 3-cylinder mounts (e.g. Suzuki Swift vs. Geo Metro/Chev
Sprint).
The 4-cyl mounts offset the transaxle further to the left (to accomodate
the longer 4-cyl engine block) and will give you roughly 4 more inches
of space to mount the motor.
See here for photos illustrating the difference:
http://www.gassavers.org/showthread.php?p=32242#post32242
FYI, the "motor" in the photo is about 15 inches long, and the adapter
plate is about 5/8.
If you do use the 4-cyl mounts, you'll have to also use the axles and
the shifter linkage & "control rod" from the 4-cyl car. (I happened to
have a dead 4-cyl car available which is why I did this.)

Subject: Re: Blind EVs
On this subject.. and VERY EV centric.
A couple of weeks ago I did one of my political events with Prius blue and
the White Bird from Wenatchee. The Event was in Olyimpia, Washington. The
capital of our state for you Right cost listers.
And I drove Sage, my Ford Escape Hybrid. Since I was not showing my Hybrid,
I was there for support and to learn more about this years Plug in messages
from our State's leaders. I had to park a couple of blocks away from the
display location. I found a spot for public parking, and hoofed it back
towards the capitol Building. Crossing the main street, It's 4 lanes or
more. My first thought was what a over designed Safe for everyone type
crossing, Yea I could have been in a wheel chair and deaf and blind and
still made it across there. Hey this is right out in front of the Capital, I
am sure it meet all current codes and some that I have never heard of. Great
I was in a hurry and it was handy. It had Beepers, it had lights and it was
full of congress people.
What I didn't see and what was impressive, happened later.. I had to go
make a Dongle for showing we could use a "Standard house hold current" for
recharge. This is one of the political requirements, it is just so Damned
important that the world has to see a 120 volt 15 amp cord hanging out of
any Plug in, That I get sent out to destroy a percectly good extention cord
just for the cameras and the masses to see. Be very certain it was a #12
gage industrial grade cord that was sacrafised for the cause. Not some
whimpy 16 gage zip cord. You send Madman to make a cable.. it's coming back
about 2x the size you thought it was. But..back to the story... I hopped
into Sage and left like on a mission...'Cause I was. And I then had to cross
this Cross walk. with a Sea of folks using it. OK. Slow.. and quite, and
then the street lit up with flashing strobes... in the Actual road surface,
Whoa !! now that's cool!. And as a driver.. that's not blind, but may be a
little hard or hearing.. THAT got my attention.
You can't drive blind, But you can drive Deaf. So..... the drivers need
visual clues. Beepers aren't going to help a driver see anything.... The
drivers are the ones that make the life and death decisions while driving...
not the blind guys stepping off the curb.
This whole argument boils down to personal responsibilities and the
defensive driving skills of the driver, NOT the EV or the ICE or the
Kenworth, or the Rice Rocket bike.
So this Thread has made it clear to Everyone on this list, Becarfull out
there we drive quite powerfull vehicles that most folks can't hear. So..keep
a watch out for pedstrians.
I an sure that my drivng instructor said the same thing when I was in
highschool in the 70s...

Really???
I thought inductance had a little to say about that fine little point.
And I wonder how Otmar can read that 20Khz switching hash and really have
the motor voltage locked to 170 volts.
Also the arcing on the brushes also seams to look like 170 volts not full
pack voltage.
So..I am not sure Physics supports your Theory.

I'm not sure if gas mowers have improved much over the
years but my my hacked together electric craftsman
mower is batteryless and I haven't found a reasonable
replacement for my acre yard.
Is there anything new out there I'm just not finding
for an electric mower that would handle that area
without taking days to mow?
I can only think of two options and I'm not sure
either would work.
I have thought about converting a gas reel mower. I'd
think the reel mower would be more efficient then a
tractor with a hydrostatic transmission. I don't mind
the walk but would it do at least half an acre if I
used two batts instead of the one the evalbum one has.
http://www.austinev.org/evalbum/546
It just says 2 small yards. Here in some towns a small
yard is the 10ft to the curb in my town it is an acre.
My 2nd option is a trailer for the sears and stick
some big batts in there. There isnt' much if any space
up front I only had 42 volts of 30amphr bb600s as all
that would fit and that took about 4-5 charges to do
my lawn. The mower normally pulled 60-80amps when
mulching. If I put 4 EV145s in a trailer that would
add roughly 400lbs which I don't know if it could
pull. If it could and it didn't up amps that much it
may mow my yard.
If I had another use for the batteries, had a free
reel mower sitting around or had spare batteries I'd
just go do it. But it is all a little expensive to get
the stuff only to get disappointed that it won't work
and be stuck with stuff I can't use or return.

Do you also need a diode across the motor with a contactor controller?
Seems like there will be a slice of time, on the order of several
milliseconds, while one contactor opens and the other closes, during
which the motor needs to freewheel.

Thanks to Felix Karamer and Cal Cars News for bringing these to our
attention. These 3 video pieces are extremely GOOD on the subject of
PHEV's and BEV's especially the last and un-edited 17 minute interview
with TESLA.
Enjoy !!!
My Netscape browser had some problems bringing them up, but my FoxFire
worked just fine.

Well yeah, the Friendly Robotics Robomower.
It's designed to run unattended. Earlier models you'd put in the yard
and press Start, later models have a docking station that they leave and
return to on a programmed schedule (can't automatically go between
unconnected lots like back to front of course). You have to stake down
a closed loop permeter wire to indicate your yard. It is slow, can take
hours or even multiple charges for a decent size yard, but being
unattended runtime is not especially important.
It's a pretty good system. Also it's just freakin cool. It is
expensive however.

This can be used to reduce sparking, but is not required as contacts do not
die from a voltage spike like electronic controllers, you only see a flash
between opening contacts. It may increase the life of contacts, so the
anti-parallel diode can be an investment in longer contact life.
(Anti-parallel means that it is placed in parallel to the motor, attached to
both motor contacts, but the current can only flow though in the opposite
direction from normal battery feeding, otherwise it would never allow the
motor to run.)
Note that the diode must be able to survive repeated currents to the level
of the max motor current, so it must be a big diode or many parallel! For
example, if you expect to see 600A motor current, then the diodes must be
able to get at least a 600A peak every time you switch "gear" through the
contactor controller.

I'll gladly admit that I sometimes miss the finer points of motor
dynamics, so if the great madman would care to explain what I missed
I'd be happy to listen and learn.

Well my flux capacitor is already finished, so as soon as I perfect my Mr.
