Ben Graves put AC into his '78 VW bus. I know he got some of the
components from Vintage Air.
The neatest thing about his installation is that he has the compressor
belted to the motor with an electric clutch on the motor shaft.
This clutch is energized when he steps on the brake pedal so he has
regenerative braking. He says it keeps the bus cool in stop and go
driving around St. Petersburg. No good at highway speeds but that's when
he opens up the safari windshields.
I'm inclined to believe him, as a Michigan resident I have to listen
when a Florida resident talks about A/C.
Get in touch with me off list and I'll get you in touch with him...

That's easy. Should I reduce the 5.6 amps? That's a bit more difficult but
doable. 5.6 amps is about 2.5% of a 225ah battery.

Page 10 says the short circuit current is 100% of the rated current, so it
will work as a battery charger.
The voltage trim is only 10% so you will need to be careful choosing the sum
voltage of the modules.
The Max charging current will be limited by the lowest current module in
series.
It says the modules share current within 1% when operated in parallel,
therefore that is an option.

I'm trying to find a way to get a Sparrow from Northern California or
Portland, OR back to the SF Bay Area, CA at the end of July. Tried to get a
quote from auto-transporter.com, but their webform doesn't list the Sparrow.
Included details about the specific but filled out the form stating that is
was a Honda Civic (because they lack an "other" category and you cannot
submit the form without picking from their list). They quoted $750 for
Portland to SF, but when I talked with them yesterday they claim that is
based on the Honda Civic listing and they never got the comments I submitted
on their webform. Might be higher; will be talking with them today. If
that's true, then they might not be a reasonable option.
Anyone have any other recommendations (due to my short timeframe)? Best to
transport a Sparrow on a flatbed or enclosed van. Actual space requirement
is about 8'2" x 4'5" plus clearance. I've also priced out renting a 10'
Uhaul truck, but to fly up, rent and gas back comes to about $650+, plus one
day of my time (SF/Portland/SF).

I got rejected from the VA DMV for NOBIGAS. They said they thought it was No
Big Ass. Then I tried NOBYGAS and everyone kept asking what NoBeeGas was. So
my tag now says ELEC CAR. Hard for the bumkins to misinterpreted that.

If this goes back to the discussion of putting aluminum heat sinks *on*
the buss bars to improve cell cooling, why make your heat sinks out of
aluminum? Copper is a better material than aluminum for a heat sink, in
terms of thermal dissipation. The only reasons copper isn't used for
heat sinks in general are cost, weight and ease of fabrication. Just
solder some copper fins to your buss bars, and while you're at it coat
the whole buss bar with solder. Or mechanically attach the fins and dip
the whole thing in solder. Copper hates acid, and the solder will
protect it.
Years ago the Honda factory motocross team had two seemingly unrelated
problems that were solved with a single clever solution. Their engines
were running hot. They wanted to improve handling by lowering the polar
moment. They could shave weight at the ends of the bike, but they were
already at the weight minimum. The solution was to machine cylinder
heads from solid copper. Better heat radiation, better concentration of
mass right where it needed to be. Normally at the end of the season
they crush the bikes. On these bikes they saved the copper heads.

Yes, getting a patent is more your perseverance of the legal system than the
merit of the invention. In fact the patent examiner sends "prior art" to get
around since the actual patent is how the claims are worded so there are
multiple patents that appear similar. Doesn't say much for the patent system
and I never got any money from my 4 patents, but looks good on a resume
anyway.

I know that Bolder Tech went out of business. I was wondering
about the TMF technology it seems someone would have picked this

Are the TMF cells not being manufactured by anyone. I see the

Mine, too! Victor has a good solution. Hang it in an old inner tube from
under the car. I think he even filled the tube with water.
I think a better type of pump would work, by being be a lot quieter and more
responsive, too. All that is out there seems to be diaphragm pumps. I'd
think a higher speed motor coupled to a rotary vane pump would work better,
and be very smooth, quiet, and not have as much "on" time. It'd be smaller
too!
To work good, it should have a circuit attached that ramps up to speed to
eliminate a 12V current spike. I don't think there is enough market for me
to design one and make any money, but I could make drawings and post them if
there was enough interest. It would take quite a while, as I don't have
software at home right now.
Anybody care to recomment a free CAD program (machanical) that will export
DXF? Comments on the type of pump that would work?
I know some have converted to manual brakes. Performance brakes
(http://www.mpbrakes.com/) even tells you how to do it to some degree. How
well do they work, and what (specifically) was involved in doing it?

Hi All,
Just uploaded a few new pictures of my progress if anyone cares to look
at 'em. a little suspension work, a little battery box work, a little
motor adapter.
suspension: I'm pressing out the old rubber bushings, sandblasting
everything, painting it all with POR-15, and pressing in the new
urethane bushings. should look and perform pretty good once it's all
back together (this summer I hope...). New springs, strut cartridges,
bushings, bearings ETC
battery boxes: I have finally decided exactly what I'm doing for
battery boxes in the rear. I am going to put one batt on each side in
front of the rear axle (directly behind the seats), which will take
some careful modification to the unibody. also four batteries in a box
hanging down below the floor behind the rear axle. When it's all done
the original carpet will will go back on top and you'll never know
there are batteries under there! this setup will give me good
structural support of the weight as well as keeping it low and centered
and very close to (or better than) stock
motor adapter: because not many folks have converted a 240Z (or any
other Zs) I had to do most of the adapter stuff myself. I did buy the
actual adapter plate from Rod at EV Parts, but the spacers and actual
shaft coupler I had to design and have made at my local machine shop.
for the coupler I had my machine shop friend cut off the end of the
crankshaft from the original engine, bore it out to the motor shaft
diameter, put a keyway in it, bore a larger hole from the flywheel
side, and press in a plug with a pilot bushing. careful sizing of the
plug will keep the whole assembly from sliding down the motor shaft
when I step on the clutch (plug is slightly larger in diameter than
hole in flywheel). making this all work also means I have to take a
little bit off the end of the pilot shaft. hopefully putting this all
together early next week.

The '04 Toyota Prius has an EV button, will be in production within 90 days and its
$20,000. So, the "big automakers" now produce an EV that is actually affordable.

I've used switching supplies as DC-DC converters by Cosel and others
90-240vac = 126 - 336Vdc. Also if they have a PFC front end they can be
operated at lower DC, about 90Vdc depending on the manufacturer.

What is this EV button you speak of? If you're referring to the "Start"
button, I can assure you the first time you press it, the gas engine
comes to life. There is no way I know of, on the current Prius, of
which I own one, to force the gas engine to be off, other than running
out of gas. I have never seen any indication that the new Prius is
different in this regard.
Also the NiMH battery in the Prius won't take you more than 5 or 6 miles
by itself. I know this from first-hand experience.

I use a CL-60 by Keystone in series with the Gast vacuum pump. I barely hear
it now compared to before. An NTC that drops from 10 ohms to .18, max run
current 5amps. Keystone-Thermometrics has different flavors of inrush
current limiters based on requirements. The pump is also mounted on rubber
poochies on the frame.
(I like this Jeep better than the previous marshmellow car-pod for mounting
stuff and sinking batteries below the floor).

About 70% of the pattents I've read would not stand up to challenge.
I had this conversation with the motorcycle designer Tony Foale when he
visited. A University department had obtained a pattent on leading link
motorcycle forks. Their pattent was for forks of greater than a certain
amount of latteral stiffness. Not a methon of achiveing such stiffness, but
the stiffness itself! This is clearly invalid, but they used the threat of
legal action to protect the pattent to shut down two rival fork
manufacturers. Tony, who was marketing his own fork at the time told them
where to go and heard nothing more.
More than once I've heard the advice not to pattent if you're an individual,
it's a waste of money.

If we literally wanted the cheapest cost per mile, we'd all drive
10-year old beat-up econoboxes. But the "best" choice is rarely if ever
defined by "cheapest".
My EVs have generally been cheaper per mile than my ICEs, but that's
because my driving pattern is a good match for EVs, and I've gotten good
at it. For over 20 years, I've always lived in northern states and less
than 10 miles from work. This kind of driving is murder on ICEs, but
perfect for EVs.
Except for my present EV, I've always used cheap flooded golf cart
batteries. Treat 'em right, and they last a *long* time. Cost per mile
can easily be lower than gas and oil for the same car as an ICE.
On engine-related maintenance and repairs for ICEs vs. EVs, you can rig
the statistics to get any answer you want. Leaving aside obvious
maintenance items like belts, fluids, brushes, and batteries; if it's
built right and you get lucky, nothing will fail on either your ICE or
EV in 100,000 miles. But, the ICE will be mostly shot; the EV parts will
be almost as good as new.
Other non-engine related maintenance and repairs for EVs are essentially
identical to any other car. Tires, brakes, transmissions, lights, radio,
body work, etc. are the same for EVs or ICEs. The tire store or body
shop couldn't care less.
Much of the automotive world is pure fantasy. Our cars could be vastly
cheaper, safer, more reliable, and cleaner if people literally made
totally rational decisions about them. But, they don't. They buy style,
not utility. They believe advertising, not facts. They'd rather "feel
safe" than be safe. They don't have a clue about true operating cost.
They ignore all the dirty little consequences like pollution, traffic
congestion, and disposal costs.
Well, I'm not playing that game. EVs are a way to think for myself, to
pick a solution that *I* like and that's good for me; not one that's
good for the auto and oil companies!
And you know what? My game is more fun than their is!

I got my mom the robomower which works well if your not in a hurry. The 49lb
MTD Yardman for a 24V cordless electric was the lightest and best designed
with swappable battery packs. The Black & Decker was the heaviest at 65lbs.
If a lawnmower (gas or electric) is balanced/engineered properly, you should
be able to tilt it up by pressing down on the handlebar with your little
finger in the store. If you can't, don't buy it.

A note-
POR-15, while wonderful stuff, like most all urethane paints, has
isocyanates or other cyanide related compounds in it. It attacks the
central nervous system, so make sure you have PLENTY of ventilation. I
had a run in with a urethane paint and I wound up with Parkinson's like
twitching from it. Thankfully that stopped, and I learned my lesson.
