I have mine on the front and it works fine.Ive had it up to 39mph going full
out downhill. Mine is only 36V though, with SLA batteries. It works fine on
pavement dry or wet. However, the biggest difference is that mine has a
STREET tire which is smooth and grippy, not an offroad tire with knobbies. I
doubt front or rear makes *much* difference at all since the majority of the
weight to the wheels is the rider which is positioned between the axles. Yes
I understand physics and moments and all that.
Combine twice the voltage, a smaller diameter wheel, and lithium batteries
and you're talking about 2-3 times the torque on a less capable tire. Yeah,
it might slip a bit..

Why is the hub motor on the front wheel? No wonder
they have no traction. Maybe it was much quicker and
easier to integrate it on the front hub, but if it was
on the back they could have the advantage of running
the motor in the most efficient range depending on
speed with gearing. They would also have better
traction with the weight distribution.
I didn't watch the whole video, so maybe they had an
explanation.
Cool bike EV though.

My Rabbit conversion's front disc brake pads (semi metallics) are
at the wear limit, and it looks like I will be doing the
replacement job. This will be my first time on my own, as when
we converted the car back in 1994 (a long time ago it seems now),
I had the person helping me replace the brakes. Several years
ago, the shop down the street upgraded the brakes to vented
grooved rotors and semi-metallic linings for the pads. The
stopping power was much better than the stock situation for the
heavier conversion, and pad life was somewhat better. However,
the person who was in charge of that affair no longer works
there, and I no longer do business with that shop.
My #1 ? has to do with how the thicker rotor (off the top of my
head I believe it is 20mm as opposed to a stock rotor's ~5mm (?))
is accomodated by what I believe is still a stock set of calipers
(I think they are Kelsey-Hayes (sic?)). Something has to give.
I haven't seen any sign on the internet that brake pads vary that
much in thickness to accomodate varying rotor thicknesses. So
the only thing I can think of is that the pads will push the
pistons further back in their bores or that a shim or spacer of
some sort was added to the caliper housing by the shop previously
mentioned. How is it normally done?
Another shop that I contacted a couple of months ago recommended
PBR Metal-Master pads. This shop seemed quite open to doing the
brake and strut work that needs doing on the car, but they
disappeared into the ether when I started an email give and take
about which struts I wanted to get installed on the car. I've
found sources for these PBR pads on the Internet, but want to get
clear as to what is going on with the thicker rotors before I
order pads and find out they won't fit. Replacing pads looks
do-able in the apt carport. If I have troubles, I can always put
the tires back on the car and let the car down. With struts,
things are a bit more problematic vis-a-vis the apt carport scene
if I run into troubles, and I don't want the car up on jacks for
more than a few hours.
Any opinions from the Rabbit / brake gurus as to what is going on
with the thicker rotors? I have Porterfield carbon-kevlar street
shoes in the rear drums, and I'm mighty impressed with
them -they've been in there for a long time and show virtually no
sign of wear, and are capable of locking the rear tires on my
steep hill with a stout pull on the E-brake handle (the stock
organics died early back there, and didn't slow the heavier
conversion at all on the hill with an E-brake pull). But the
shop above that recommended the PBRs said that carbon kevlar
would not be a good choice for the fronts. Thoughts on that? I
think my main beef with the semi-metallics (if they are cold) is
that my blood pressure goes up a bit if I have a panic stop
(rare) till they warm up in a second, then it's tail up time as
they haul things down in a hurry. They still won't lock the
fronts unless the road surface is wet - that will probably
require upgrading to larger wheels and rotors.
I assume I need to get some Sil-Glide, or whatever it is, to help
the pads slide back and forth easier on their tracks to cut brake
drag. Let's see, brake cleaner fluid. Also will need the tool
to force the inner pad back into the bores. My master cylinder
reservoir is not full of fluid (it's at the level of the
horizontal seam somewhat down from the top), so hopefully I don't
have to remove any fluid (yuck!) to avoid overflow when I push
those pistons back (will have to get a syringe if I do).
Anything else or gotchas?

Hydratus? Magnesium rods?
http://www.fuelcellsworks.com/Supppage6510.html
Anybody know more about this?
I'm skeptical because the stock bulletin I read on it sounded like it
was written by a used car salesman.
Additionally, the legendary Tesla car early in the 20th century
supposedly used magnesium rods inserted into a container of unkown
substance to produce speeds up to 90MPH. None of us was there to
either confirm or deny if this is myth or fact. Supposedly Tesla kept
the technology under his hat because society was laughing at him at the
time and out of resentment he felt they didn't deserve it.

Subject: Your Car of the Future
Date: 11 Jan 2007 18:06:35 -0500
From: NOVA: Car of the Future <[EMAIL PROTECTED]>
Reply-To: NOVA: Car of the Future <[EMAIL PROTECTED]>
Greetings from NOVA,
First of all, I want to say thank you for taking the time to write in about our
?Car of the Future? project. It?s been gratifying to hear from so many people
like yourself who have ideas for the program and Web site.
We received a number of emails like yours saying something along the lines of
?I already drive a car (or bike or motorcycle) of the future? or ?My dream car
of the future is ??. The range of innovative vehicles (and passionate
individuals!) is impressive, and something that we want to share with our
audience. Given that we can?t include all of these vehicles in the documentary
itself, we are launching an effort to produce a Web feature tentatively called
?My Car of the Future? to profile various vehicles and the people behind them.
I?m writing in the hope you may want to contribute to this feature. Our plan is
to include 10 ? 30 entries selected from those submitted. Each entry will
consist of a photo of the vehicle/owner as well as brief text, and we may also
include audio or video clips for some entries.
If you are interested in making a submission, here is what we would like to
receive from you:
MANDATORY:
***A photo of the vehicle***
We would prefer a color image that shows both the vehicle and the individual(s) behind it. You may send multiple images for us to select from. You must have the authority to grant WGBH the right to publish the image on the NOVA Web site (e.g. you must own or legally control the copyright in the image and have all necessary permissions to show the individual(s) and vehicle in the image) and to use the image in the NOVA series and its related materials.
You may send image(s) to the mailing address indicated below, or email electronic copies of images to the email address below. Please make sure you include your name and address when you send the image(s).
***A 25 to 50-word text piece written by you***
The text can be informal in style and ideally will reflect your personality. In some cases, the emails you already sent in, with slight tweaks, are suitable. We are looking for a brief description of the vehicle and why you drive/ride it?the key points you would want to share with a wide audience. In addition to the 25 to 50-word piece, you may also submit longer text, but we may not be able to include such expanded text on the Web site. Please note that WGBH may edit your text for style.
Please email an electronic copy of the text to the email address indicated
below and also include a printed copy of the text (with your name and address
on it) with your Materials Release Form, which must be mailed to WGBH.
***A completed WGBH Materials Release Form***
The attached document must be completed, signed, and returned to WGBH in order for us to consider including your entry on our site. After the words ?Licensed Materials,? please write all materials you are submitting, e.g. ?Image, text, and video of my orange electric car.? Please note that WGBH may post on the NOVA Web site your full name, city, and state and that the WGBH Materials Release Form permits WGBH to use the Licensed Material on the NOVA Web site, in a NOVA program, and their related materials.
Because your signature is required, you must send the materials release via post to the mailing address below.
OPTIONAL:
***Video***
If you would like to submit footage featuring yourself and your vehicle, we would love to see it. We may be able to include short clips (1-3 minutes in length) on the Web site. You must have the authority to grant WGBH the right to put the video on the NOVA Web site or to use the video in the NOVA Series and their related materials (e.g. you must own or legally control the copyright in the video and have all necessary permissions from any individual(s) appearing in the video and permission to have filmed the vehicle in the video). Please DO NOT include ANY music on the video.
Please send the video, clearly labeled with your name and address, to the
mailing address below.
* **Audio***
You may submit an audio file in which you talk about the vehicle and why it is your choice of a ?car of the future? (at least today). Again, we may include short clips (shorter than 3 minutes) on the NOVA Web site. You must have the authority to grant WGBH the right to put the audio recording on the NOVA Web site or to use the audio recording in the NOVA Series and their related materials (e.g. you must own or legally control the copyright in the audio recording and have all necessary permissions from any individual(s) speaking in the audio recording). Please DO NOT include ANY music on the audio recording.
Please send the audio, clearly labeled with your name and address, to the
mailing address below.
DEADLINE:
The deadline for submissions is Monday, January 22, 2007.

I think you are looking for Rabbit GTI brake pads. The Rabbit and GTI
used the same caliper but the GTI got the vented rotor and thinner
pads.
The 1980 thing kinda throws me off a little because that was a change
year. It seems you have the newer style brakes. I don't understand all
the interchange rules between '70's Rabbit front end parts and '81 up
late type Rabbit parts. Perhaps others here will have more detailed
info specific to 1980, or whatever year parts you actually have up
front.

I didn't say at the same time, just average. EV
Calulators say 150 mile range at 35mph, 80 mile range at 75
mph, the max steady I reccommend on the stock set up and
hard to do in real life, traffic for long. Higher power,
speed is available as an option. It's wthr/mile should be
between 60wthrs/mile and 130wthr/mile.
We'll see shortly what exactly it will do.
My stock pack is just 12 T105's, nothing costly.
It's not a minimal vehicle, just low drag,
lightweight. About the size of a compact car and 6" taller
with room for a 6'5" 275lb with a 5'-8" 200lb inside at the
same time without rubbing, which amazed and pleased me. It
has room for cargo and tows a trailer when needed.
>>

Ok, if ICE's put engine costs, lubes, service,
breakdowns, wear, transmission, ect. With my little, lightly
stressed because of it's excellent range pack should last
5-8 yrs allowing it to comfortably be cost effective against
ICE's. Being able to easily repair it means you have little
or no mechanic costs, body repairs from rust, time wasted
waiting to be repaired. It uses low cost, widely available
parts, both EV and glider ones.
I call it Freedom EV because you get freedom from big
auto parts gouging, big oil, mechanics/dealers, ect, saving
really big bucks ;^D
That's why I don't include battery cost. But if you
did, it would be about
$.02-.04/mile.

Yes that's my plan, using a much lower drag vehicle,
designing it to take advantage of EV's best points and
minimizing their bad points. By doing it that way, reducing
the power needed, thus a smaller battery pack that gets
great range at reasonable speeds, lower costs.
Now if others would do that too, I'm trying to show
the way!!!

Why couldn't you use this controller with reversing contactors? The A2
(plug braking) lug doesn't get used by street vehicles anyway -
anything faster than a jog and you've got too much energy to safely
burn off (yes, "burn off", not regenerate).
As I understand it, the diode also acts as a freewheel diode for the field
(or is it the armature? I should look up the connections before shooting
from the lip), reducing the bemf arc on the reversing contactors.

Tesla's car story was a hoax, and a fairly crude one. The story is
supposed to be a 1967 interview by Derek Ahlers with Peter Savo who
claimed Tesla was his uncle who showed him the Pierce Arrow in 1931.
First is the apparent technical impossibility of the demonstration.
Second would be a mystery of how Tesla was so consistently desperate for
money, why would he not pursue such a wildy successful, immediately
practical invention. Third, there is no period account of Tesla ever
working on such a project, though he did pursue "wireless power" by
simply broadcasting immensely powerful radio waves. The account claims
something like "ether power" or "radiant power" (not magnesium in a
container of unknown liquid) and radio could never do what was claimed.
The story clearly claims Tesla speaks of free, limitless energy that
comes from a natural yet unknown source, not a radio tower. Tesla was
never into claims of any such "free energy" devices. There is no patent
or period account of such work until this guy makes this lone claim in
(supposedly) 1967.
But the simplest answer is Tesla's family tree is a matter of record and
he has no nephew by the name of Peter Savo. If Ahlers did exist and did
interview somebody named Savo, that person was a liar.

G'day All
If anyone wants to try this, I've got a couple of inductors that are rated
5mH and 10A. $15 australian each, about $11.25US each, or trade for things
I can use.
Be aware they are 2.6kg (5.7lb) each. I'm in Australia, and according to

Wilde Man,
My wife-unit gave me a copy for Xmas, and I've watched it at least three
times now. I catch something new with every viewing, and it's great to play
it when people come over to the house, like recently when I had a captive
audience of teenagers! Did you catch the murder of the trolley car system

Thanks Danny.
I was well aware that the "legend" (and various versions no doubt
floating about) are largely discredited.
Independent of those accounts, we still don't have any way of proving or
disproving what Nikola was up to during certain periods of his life.
His personality profile is consistent with one who's ego might take
precedence over unveiling something out of economic necessity.
Anyway, what seems more curious is the correlation between the Hydratus
technology claim and some of said mythology. Is Caltech, Nasa/JPL, and
Alchemy hoaxing us?
Anybody have insight?

I did the intelligent thing and called Kilovac to ask. It turns out that you
are completely correct. There are magnetic blow-outs, and the "-" stud goes
to the "-" battery pole. I've only been wiring things up for 35 years, and
I still can't get that +/- thing with batteries the right away around. Why
should sources be backwards from sinks?

I have mine on the front and it works fine.Ive had it up to 39mph going
full
out downhill.
???? I've had my non-electric bike going 35 downhill without even peddling.
Now if I could just find a route that was downhill all the way to work and
back :-)

Hello all ;)
My truck has 24 T-125s on board. Its 20hr rate is 240AH. Now - since I am
usually pulling 100-150A, peukert dictates a much lower usable capacity,
say 105 AH. If I were to put, say Thundersky LiOn batteries in the truck,
I should get about the same range with 150AH?
Is this correct? Or is my reasoning flawed?

Their proposal is to make hydrogen on-board with consumable "magnesium
and water". There must be some details left out, magnesium and water
doesn't make hydrogen in itself that I know of. There's magnesium
hydrides (don't know how H2 is extracted) and I assume putting magnesium
in acid makes H2 too. The energy density can't be all that high, but
then it's quite difficult to store even a few pounds of hydrogen as a
gas too. Of course the reagents are consumed in this reaction and
they're suggesting the resulting liquid, slurry or whatever would be
collected and "recharged", which would involve a large energy input and
brings up additional cycle efficiency issues.
This is not the first thing I've seen suggesting an on-board chemical
reaction to produce hydrogen for a fuel cell. The plan is not a hoax,
well there's no fakery, but its practicality for anyone is in question.
Like many ideas out there, sure it's worth looking into and attempting
to develop. I doubt it's all that remarkable a solution though, and we
don't even have an affordable fuel cell solution anyways.
A more common and potentially more "rechargeable" solution is a solid
metal hydride powder which adsorbs hydrogen and can release it when
heated. That solution has seen serious consideration, there are still a
lot of issues though.

I was well aware that the "legend" (and various versions no doubt

Independent of those accounts, we still don't have any way of proving or
disproving what Nikola was up to during certain periods of his life.
His personality profile is consistent with one who's ego might take
precedence over unveiling something out of economic necessity.
Anyway, what seems more curious is the correlation between the Hydratus
technology claim and some of said mythology. Is Caltech, Nasa/JPL, and
Alchemy hoaxing us?
Anybody have insight?

Tesla's car story was a hoax, and a fairly crude one. The story is
supposed to be a 1967 interview by Derek Ahlers with Peter Savo who
claimed Tesla was his uncle who showed him the Pierce Arrow in 1931.
First is the apparent technical impossibility of the demonstration.
Second would be a mystery of how Tesla was so consistently desperate for
money, why would he not pursue such a wildy successful, immediately
practical invention. Third, there is no period account of Tesla ever
working on such a project, though he did pursue "wireless power" by
simply broadcasting immensely powerful radio waves. The account claims
something like "ether power" or "radiant power" (not magnesium in a
container of unknown liquid) and radio could never do what was claimed.
The story clearly claims Tesla speaks of free, limitless energy that
comes from a natural yet unknown source, not a radio tower. Tesla was
never into claims of any such "free energy" devices. There is no patent
or period account of such work until this guy makes this lone claim in
(supposedly) 1967.
But the simplest answer is Tesla's family tree is a matter of record and
he has no nephew by the name of Peter Savo. If Ahlers did exist and did
interview somebody named Savo, that person was a liar.

electricity has an extra advantage over oil based products, you can
make electricity at home, but you can't make oil at home.
If the world suffered some catastrophy and we needed to communicate,
hand wound or pedalled generators become the fuel stations to keep us
going, no matter how much you pedal you cannot make oil, but you can
make a surprising ammount of electricity.
Large scale electricity ought not become too expensive as long as
investment in renewables is made. If that investment doesn't get made
we risk seeing electricity prices rise because fossil fuel prices
rise, but when fossil fuels run out and renewables have to be
installed would we see a relative price drop again ? You can call me
cynical but I think if any utility company or governement energy
department can justify raising prices, and therefore revenue, they
will, and then it is all but impossible to prove the price should
come down again afterwards.
We need to get the investment made quickly and in a sizeable ammount
in renewables, either home renewables or centralised public
renewables. If we don't we make the future much more expensive.

Afraid you're beating a dead horse. Force and energy are two entirely
different things. Putting two opposing poles together is really no
different than a spring- and you can't make a spring bounce outward
without compressing it again each time. The answer has been explained
countless times over the last hundred years or so.
I should mention that while I have no doubt you are well-intentioned,
discussing getting free energy from magnets, Tesla's free electric car,
etc are squarely in the realm of quackery and quite off topic for
electric vehicles which are based on accepted principles of magnetic
motors, chemical batteries, etc.

The beauty of EV's is they can run on almost
anything eff by turning it into electricity very effiently.
And this property means electricity will be the
most available, cheapest souce of transport power in the
future, even when paying more for it.
My eff EV will get 100wthrs/mile and any future
production EV should get under 150wthr/mile sedan,
225wthr/mile, for SUV size EV. This equals 230mpg, 160 mpg,
100mpg equivilent.
Even lead mine conversions normally get around 333
wthrs/mile making cost equivilent of about 75 mpg!! All
calcs use $.10kwhr costs.
And you can make oil at home, I do used veg oil now
and will evenually make oil, NG from yard wastes, ect, FT
process, off topic here.
And as you say, you can make RE at home making your
energy future secure. I suggest wndgens for those who's site
that works at.
There is no lack of energy, just the machines, will
to do it. Stop subsidizing oil at about $1/gal according to
the WSJournal amoung others, would help make most all forms
of RE cost effective.
In a couple yrs I'll be making electricity for
about $.01kwhr with my non dam hydro to power the EV's I
sell!! This tech amoung others like wind, nuke will keep
electric costs low comparitively.

Wrong on both points badly. Pedal power doesn't get
it for more than a few wthrs.

Except in a few places like, as Bob says, Corupticit,
electric prices are very reasonable. If you don't believe
me, make some of your own. Like in sailboats, while the
energy may be free, it costs a lot to catch it.

We'd do much better going to conservation, eff
instead will do much more in the short term.
