Boy I sure would like a Turbine gen cart... and I DO know how to rectify
that kind of frequency... But I don't have 6K$ to blow on a toy that is
probably damaged, and needs serious engineering just to get back on line.
Danny, any insight into what made the turbine un reliable??? operator error,
or actual mechanical weaknesses??
Kowning what these list for, and what he is asking makes this thing look
like a good idea for the Power R&D types.
You think a Big block a a cam and headers can make some noise.... 'Bines
can make walls move and melt things at a distance. Just the kind of thing
for commanding respect from the Gas Guys at a Drag race.....
Ok when I have 6K$ in mad money..... and no Debt...

Ok $700 bid....
I have had the pleasure of actually looking through the Capstone sales sheet
this year... and it amazed me that they busted Butt to deliver 60 Hz to the
High power EV crowd. Like Hello!!! we need DC anyways.
I suspect they just rectifiy it with good high speed low forward drop soft
recovery diodes, Spendy but available. Then they have a DC bus and a 60 hz
inverter sucking off of that with a a nice solid clock and current limiting
controls. Nice... for The Guy who needs sharp Grid qualuty 60 hz.
Batteries don't, so just can the inverter, use the DC Buss and a simple
current limiting Buck converter, and Voila!! varaible DC with single stage,
One Igbt and one diode.... This is also called a EV DC speed controller...
I and Otmar and many others know a lot about.
And it looks a awefull lot like the 1/2 the power deck in my 75Kw charger...
If the gen stage is permag... well... volts and amp is rpm and torque....
and like no exciter, and no funky controls, Spin it, adjust the load... and
you are off!.
With Boost Buck stage like the PFC50 chargers, What ever the generated DC
rail... it can be stuffed into what ever battery you have on hand.
God I would LOVE a turbine......
It would be another major distraction Like having Gone Postal in your shop
for a Month.... Charge drive.... HUmmm Need 2 screw and a roll of Tape...
Back down to the hardware store.... Oh darn forgot the mail and the Bank...
back down..

Ummm to be polite to me... the charger won't be hurt by the controller wave
forms....
But the charger while running is QUITE a source of RF.
I have busted Butt to give you all the power I can, and spent little time
making the charger quite.....
Fast switching rates makes for low losses, and nasty rise times.

Hey, I said they're not for a high performance EV. ;-)
It seems that some members of the AGM crowd, not all, spend a fair bit of
time and effort knocking floodies. That's OK, we can take it; but the
newbies should know that these solid, unassuming, modest guys do a
reasonably decent job for people whose main goal is an EV that's economical.
Every situation is different, but by my calculations for a particular case,
flooded golf car batteries cost 2 cents per mile; Optima G31s cost 14 cents
per mile. That's a huge difference! If what's driving a newbie to EVs is
the high cost of gasoline, why steer him toward the most expensive battery
option?

I'm not sure what NJ is referring to. I know nothing about that turbine
but it is DC not AC.
From what I've heard Capstones are supposed to be really reliable at
least in normal service. Automotive service is always a trick.
Changing power levels, starting/stopping it, and vibration are often
problems. The use of an integral controller designed by the mfg should
have taken care of that in theory. Also I'm not sure how they filter
the large volume of incoming air, if they don't filter it that could
cause problems.
If only I lived some place with a natural gas well on site- 40kW is
enough to run my whole house.

Subject: Re: Microturbine generator on eBay
Yaaa right. I might think about giving $500 for it. That's the
microturbine that nailed the final nail in AVS's coffin. About as
reliable as a wet match. It's set up to run on compressed natural
gas, not terribly useful for an conventional car at this point.
You'd have to be a pretty clever dood to use the output of the
generator. It's a three phase PM alternator, 4 pole I think. At
96,000 RPM, that's 3200 hz. that will require some rather expensive
high speed, high voltage semiconductors to use. I'd not expect to be
able to do anything with the controller unless you're repairing an AVS
hybrid bus.
Of course, it might be fun just to fire off to make your neighbors
think you're driving a turbine car :-)
The seller is this guy in Ooltewah, TN a couple miles away from me who
ended up with all the AVS junk when they cleaned out the building to
sell it. He keeps listing this stuff for outrageous prices that never
sells. You'd think he'd learn. I need to stop down and have a chat
with him :-)

The turbine might not make a good direct power source for an EV.
Historically turbines have been slow to adjust power levels, at least in
ways that are safe for the turbine. At least that's what I've heard.
And things can always change with new technology. I mean you might need
to rev the turbine up to max rpm in order to get the full power for
accelerating from a stoplight. If that takes awhile you might not be
able to throttle down for stop signs and such in the city or you'll have
problems getting the power up again to accelerate. The batteriest would
get you through this problem.

Umm Like Duhh!
Of course you would not run the turbine as a direct drive supply, the batteries
would level the load, and at 30Kw and with a large EV say a Buss, After about 10
minutes of hill climbing, the genny would be running flat out and not keeping
up.
So... a small turbine run flat out is not a bad operating envelope for a
Series or parallel hybrid.

Yes thanks 'll check for spacers. I was also told that a machine shop could
take the drums and re-drill & relocate the 4 studs and plug the existing
holes but the spacer thing sounds better/cheaper. If you stunble into the
supplier email me offline,

that's what your dealing with. It's not safe to run those on there as
they'll loosen on their own. I did the same thing with my GEM car, I found
14's for it and had to have spacers made. If you check eBay for wheel
spacers there is a seller who will make you anything. On the GEM it has a 0
offset, not sure of the bombardier is the same or not, but I had 38mm offset
wheels so 1.5"~38mm for the spacer made it fit right, and they can make you
the proper adapter. They were $140 for a set of 4, which is cheap.

Thankyou to all for answering some of my questions about charging.
I am wondering now why all of us EV enthusiasts are not making straight for
the UPS computer systems use, to relieve them of their old AGM batteries
they change every 18 months, most of which have never been used in anger.
Perhaps I am missing something but if I can find an AGM battery that's 18
months old for 50$ why buy flooded batteries, or are they not up to the job
?

Lee,

I was going to show the system in our test EV at the
Stanford Rally, but my wife just "crash tested" the
system for me yesterday morning. At 60mph, she
rear-ended an idoit entering the HOV lane illegally
from a dead stop. The trunk of the almost brand new
Toyota Camry was smashed all the way into the rear
axel. Our Paseo EV suffered relatively minor damages.
Everything still works. No electrical fire or shock
hazard because of the weather proof insulated design
and the optical isolation protections in the system.
No high voltage is present in the cabin. 2 batteries
did shift far enough to touch the metal battery
hold-downs and create a momentary arc thru the
chassis, but, the collision was at 60 MPH. I am happy
with the outcome. No one was hurt.

Well, might as well post this for everyone to have. The eBay user is
"wheeladapters"
http://search.ebay.com/_W0QQfgtpZ1QQfrppZ25QQsassZwheeladapters
They'll make anything, $70 for a pair, $140 for a set! There is a shop locally
that makes these things and they are at almost $100 each for the same 4 on 4"
to 4 on 100mm 1.5" spacer adapters that I got from them.
With the adapters at least you don't modify the vehicle and therefore it can
always go back with nothing special.
BTW, you can get these wheels at pepboys for $50 each!
http://www.meguiarsonline.com/gallery/data/500/19314_s-med.JPG
They are 4X100mm, and they're actually pretty light, I mounted an old set of
Insight tires on them and it made a huge difference as far as rolling
resistance.
Good luck

that's what your dealing with. It's not safe to run those on there as
they'll loosen on their own. I did the same thing with my GEM car, I found
14's for it and had to have spacers made. If you check eBay for wheel
spacers there is a seller who will make you anything. On the GEM it has a 0
offset, not sure of the bombardier is the same or not, but I had 38mm offset
wheels so 1.5"~38mm for the spacer made it fit right, and they can make you
the proper adapter. They were $140 for a set of 4, which is cheap.

larger or can I just run like that as it doesn't appear to wobble? Or I

Welcome to the list.
I too am about to start a similar converstion. I have a 1987
Cabriolet with an automatic transmission. I figure I can always swap
the transmission with a standard later if need be. I am starting with
an old Jack & Heinz g-32 shunt wound motor/gen and a contactor
controller.
Since it idles, the tranny will be going all the time. I have
not decided if I will or can use the torque converter or not. I also
have to figure out if I need an external pump for the tranny. My tranny
is not computer controlled. Being shunt, I will have some regen down to
the rpm the tranny freewheels, I am guessing around mid to upper 20's
when in drive. I am thinking this will smooth out the regen and voltage
change jerks.
I know this is a big experiment and I am not expecting nor
designing for performance. Since I have the car and motor already it
won't cost much more and I can always change the motor and tranny later
if I so desire.

Subject: Have I found the ultimate EV discussion list?
This is incredible,
...
Project about to undertake: Electric 1996 Golf Automatic.
So here is my plan. I am looking for help and guidance, anyone that says
I
can't have electric windows, air conditioning, alarm systems, Rear
window
defogger and an Automatic transmission please don't bother. Well unless
you
have REALLY good information.
My plan so far:
Advanced DC motor 9" traction motor. Is this too big?
18 - 8 volt Trojan T-875 batteries.
Controller, My own, with regen, I find what's available ridiculously
expensive.
Battery charger, my own, Child's play, will be 3 step, variable rate
absorption, float, on demand equalization. PIC controlled.
Air conditioning, yes but not sure how yet.
PS and PB, vacuum pump for the brakes, not sure on the Power Steering.
Auto trans. why? Doesn't make sense to shift if this is a futuristic
car.
(Born and raised on stick shift. This is the first auto in the family in
15
years)
VW Beetle auto has a final drive on 4.875:1. This equates to 5200 rpm in
top
gear at 70 mph. Beetle trans will fit into the Golf. Electric motor
connects
strait to the transmission, no torque converter used. Oil pressure will
be
created using an external dc driven pump. Over drive gearing will be
discarded. VW trans is electrically shifted and already has it's own
shift
computer which will be discarded and replaced with a PIC based computer
to
change the shift points as needed. Can be programmed to upshift when
touching the brake lights the help with regeneration.
Batteries: I plan on cutting and welding on the body. A 10 battery box
under
the floor where the fuel tank and spare tire are, a box with three
batteries
under the rear seat and 5 more, not sure how yet under the hood with the
motor.
I have been in contact with EV of America, some of my choices are by his
recommendation.
I am not yet sure where to buy from, his prices are kind of steep, well
so
are everyone else's that I have contacted.
Any info from the gods amongst you will be greatly appreciated. I need
to
get this project done before all the gas stations close in the spring.
:-)
If it is ok with you guy I am going to put this up large in the garage

I'm a little puzzled why one would spend $140 on adapters so that they
can use a set of 4x100mm rims. 4x4" rims are available new or from a
junk yard, so as long as you have to buy a set of wheels for the vehicle
anyway, why pay for wheels and then pay another $140 for adapters
instead of just buying the proper wheels to start with?
Note that the adapters are 1.5" thick, which means that your wheels will
end up spaced 1.5" further out. If you are using wider than stock
wheels with appropriate offset to correct for this it may not be an
issue, but if you are just slapping on whatever wheels you can find you
could end up with tire and/or wheel bearing wear issues.
Cheers,
Roger.

Was it a "crossover" cable instead of a "patch" cable? If it was a
patch cable, it should have worked just fine. Check it for
continuity. An example use for a crossover cable is to hook up two
PC's directly, network card to network card. A couple of the wires
are swapped in the cable to do it.
Category 6:
"Same as Category 5E, except that it is made to a higher standard (see
comparison chart below). The Category 6 standard is now officially
part of the 568A standard. "

I am wondering now why all of us EV enthusiasts are not making straight for

months old for 50$ why buy flooded batteries, or are they not up to the job?
Hi John
Grid corrosion will have reduced the available aH available, and by
variable amounts (balance issues). Ex-UPS batteries may be useable, but
they are also not designed for EV-level use - an AGM isn't an AGM identical
in all aspects.
The trick would be to get a job in control of a big UPS and fit it up with
Optimas or Orbitals and regulators, then in 18months.....

What you are seeing is the difference between 4 inches and 100 mm. It's a
small
difference but enough to prevent interchanging wheels. Small trailer wheels
should
fit your Bombardier.

Hi,
I was curious how critical it is for the rim lug nuts to seat? I have

Does anyone know why this guy put a diode on the DC-DC input+ line?
(look in schematic on wiring page, the diode is a bit hard to see, but
it's there)

Really ???
That surprises me. I do not remember the the full power DB levels...
The same power level military Gen carts are ear Pro only.
But still I would love to have a Capstone to play with.
