True.

He says it has no trouble passing WOFs (except for things like
mechanics wondering where the exhaust is an' stuff).
But yes, it will be only a matter of time until it rusts out,
(especially since I can't garage it) at which time I can get a
newer donor car and re-use the parts.

In NZ, all cars have to pass a WOF (Warrant Of Fitness - mechanical
inspection) every six months. The tests include looking for
structural rust, so if he can sell it with a current WOF I can be
reasonably comfortable on that front.
But thanks, it's a good point.

If you get the design done, Office Depot sells blank bumper stickers that
it claims are water resistant and inkjet compatible. Templates for word

Subject: Portable GFCI protection?
Hi,
I'm looking for a portable GFCI protection for a PFC50 charger. Does anyone
know of a place to buy an extension cable with a 220 volt 50 amp GFCI
protection built in?
Would I need a different GFCI for a 220 volt 20 amp rated circuit?
I have seen lots of nice cables with GFCI built in for 115volt 15 amp and 20
amp circuits. Can I use a 20 amp (115 volt) one on a 15 amp (115 volt)
circuit and still be safe?
Thanks

Hi Lesley,
Call me a scrooge if you like but im looking at negotiating down a 10 inch
7.5 hp motor and controller from the $600 they are asking for it, now I
don't know how many horse this 323 has, but if I wanted 15 horse I could
just go buy another $600 motor and controller.
Yes the parts may be expensive but I assure you they don't have to be :)
As to certification I have already enquired there and they are looking for
well engineered ( safe and wont drop out the first bump you go over ) and
vented, well secured batteries, not in the passenger compartment.
I don't see either of these as a problem.
I paid $60 for my van and I can do the work myself so the all up cost for me
will be about $1000.
I expect to spend a week or 2 doing it so even if I was paying myself I
would expect a complete vehicle for $2 to $3,000 so why would you want to
pay more ?
An add on trade me asking for a car for under $100 will net you a heap of
cars to choose from for your base vehicle, and while I might not get another
motor / controller for $600 I can sure get another one tomorrow for $1500
from Hamilton.

Not exactly. Tilley did himself in by being a con artist. He probably

Did I miss something in this thread? I thought you were talking about buying an
already-converted car; now it sounds like you're converting a van. It also sounds like
you expect to carry out a van conversion in a week or two. If that's the case, I hope
you're not planning on sleeping any time during that period. <g>
Seriously, EV conversion is harder and more time-consuming than it looks. Mike
Brown used to perform Voltsrabbit conversions at weekend "solar fairs" and the like
as demonstrations. He was using a kit, with many parts already fabricated, and
usually did some advance preparation of the vehicle. Even then it was often a race
to get it all done in a weekend.
> Yes the parts may be expensive but I assure you they don't have to be :)
Sure. There are ways of getting there cheaper -- typically used or surplus parts. In
general (there are exceptions), the less money you spend, the more problems you
have to solve and the longer it takes before you have a usable vehicle. This is the
right answer for people who (1) have more time than money; and (2) are adept at
mechanical and electrical hacking. It also helps a lot if you have someone
experienced nearby to call on for help.

Sorry to reply to my own post, but to clarify a bit:
Make two 'induction pistons'. Excite them. Collect the power.
Bonus points: You can 'start' and 'stop' the engine. To stop, dump a whole
lot of amps so you 'break' the deisel, to start, do the railgun trick to
'make' it. You'd still probably have to have a glow plug if it was cold, and
I'm not even sure as to what kind of power levels it would take on the
railgun - could one of the math gurus suggest some equations I could look
this up in?
Could this type of engine be made to run on non-deisel - i.e. unleaded? How
hard would it be to make a 'clean' version of this engine. (You have to be
cleaner than the 'average' 2 cycle - and since you'd still have to have oil,
that might be tricky.
I guess you could actually add valves and a oil pump.
How would you meter fuel into the thing? A miniture fuel injector? A very
tiny carb?
Hrm. I'm generating more questions than useful ideas here, sorry.
[I'm currently undergoing a time-zone reversal - just got back from Asia,
which is why I was off list. Can anyone identify this EV:
http://www.sheer.us/ev/pics/DCP00981.JPG ?] There are a lot of them on the
streets in japan.
[Another of my many EV-travel pics is
http://www.sheer.us/ev/pics/DCP01339.JPG - the Thais are working on a
electric tuk-tuk* - they don't quite have it yet, but they've got the basic
idea down ;-) ]
S.
* = tuk tuks, as they are somewhat affectionately known (except at 3 am),
are 2-cycle 3-wheeled motorcycle taxies that ply the streets of Thailand,
usually about 20kph faster than everything else. Something tells me if you
could make it cheap enough, the Tango would be a natural there - I mean,
lane sharing would not be a problem.. Unfortunately, in this case, 'cheap
enough' is about $1000, which is what a factory tuk-tuk costs.
They're really intersting vehicles, actually. The engine is up front, a
BIG 2 cycle motorcycle engine, air cooled - it then goes through the
transmission, which is a more-or-less standard five speed. The steering
wheel is a bike handle with bike style throttle, the gearshift pokes up
between the legs of the operator, or is operated like a handbrake, depending
on the personal tastes of the driver. Differential to two motorcycle tires
in the rear. The front actually resembles a large motorcycle.

The one issue you might have missed is the weight of the storage medium. In
a car with lead/acids, you have lead. In an "air car" you are using
something like carbon fiber wrapped aluminum... the same stuff we
firefighters use to carry our air on our backs - normally at 2215 psi, and
"high pressure" bottles at 4500.
So - if the weight is less, it might be a bit more efficient since it moves
less weight.
Now - can we pump air as fast as we pump gas? It would certainly retain the
economic structure of having "filling stations" on every corner - but
something would have to be done to avoid the heat build up of a fast
fill......
How often do you have to replace your breather bottles due to stress
wear, and what do they cost? With firefighters, these costs are
acceptable. I doubt they are for automobiles.

These are pretty good FET's, but not the best compared with the latest
available.
http://www.irf.com/product-info/datasheets/data/irfz44v.pdf
They have Rds on of 16.5 mOhm.
http://www.irf.com/product-info/datasheets/data/irf1405.pdf
This is a 5.5 mOhm part
http://www.infineon.com/cgi/ecrm.dll/ecrm/scripts/public_download.jsp?oid=27652&parent_oid=28762
This is a 4.7 mOhm part
The 60V part is good for a 36V battery powered system, I think 48V is
really pushing it, although it
can be done as Rich has.
If your looking to fill a coffee can of parts to prove your design, the
Ebay part is a good buy.
I just wonder where these parts came from and whether they were non-qual
parts from IR.

You have it exactly right. With most free piston engines, starting them
is a pain. The usual method is with a tank of compressed air, which is
recharged when the engine is running.
With a solenoid-based generator, it is easy to run the solenoids as a
motor to start it. You don't need a tremendous surge to start it in one
cycle; the pistons bounce off the trapped air at the ends and center.
Just apply AC to the coils at the resonant frequency of the piston-mass
/ air-spring, and the oscillations will build up until there's enough
compression to start.
One neat aspect of this type of engine is that it could run like the old
"dam-dam" engines. I.e. you "PWM" it like a controller, switching it
rapidly between full power and off at some duty cycle. "Bang" cycle
cycle cycle Bang cycle cycle cycle...
> Could this type of engine be made to run on non-diesel?
Yes, if you add a spark plug. However, one of the big advantages of a
free piston engine is its variable compression ratio. This is great for
diesels but a pain for gasoline engines (it makes them knock). Also, to
idle, you cut off the air to a gasoline engine; this means there is very
little air in the central "bounce" chamber for the pistons to rebound.
So, it won't want to idle.
> How hard would it be to make a 'clean' version of this engine?
The fundamentals of combustion are similar to any other piston engine.
But most of the work on free piston engines was done in the 1930-1950's
when nobody cared about emissions.

Yes, there were 4-cycle versions as well. They usually had a combustion
chamber at each outside end, with the valves and injectors or spark
plugs. The bounce chamber was then in the center.
Free piston engines often weren't tiny -- some had pistons over a foot
in diameter!

I get a lot of people asking about making an EV go over 100 miles (even 200)
per charge. They don't seem to care what the cost . So after trying to

that one dose I still get " I heard ya ya ya " . I would like to be able to
say yes for $xxx you can do it and it looks like LiIon would do it .
here are some things I guess I missed
on the 100 ah bat what load (in amps) can you put on them. for under 1 min
and over 30 min?
the 100ah is that over 20 hours ( would that be written c20 or 20c) . so at
a c1 (one hour discharge) what would be the ah.
I don't expect any "hard info" just a gut feel.

That's a great idea. and give me an idea for a bumper sticker
"Dear OPEC I am having an electric outlet installed in my driveway" got to
think about it
Mabey when posting on the EV album a pic of the outside charging (or inside)
could be included.

I think this is a deal also , and I know your ready , I want to hear all
about your "getting to know him/her" that first ride ect . My first kostov
has over 50,000 miles on it and I wouldn't sell the motor for less that
$1500 as I'd just have to buy another and don't see any ware on it , runs
and sounds just like a new one . Of course If you here grinding ect and
things are not as the say in ad , wish I could go with you and take a look ,

I like the idea.
You could make it more generic by claiming:
100% domestic electrons.
No imported energy.

Don't forget that this car (and Lesley) are in New Zealand, and the price is in $NZ,
which (like my $AUS) are worth quite a bit less than the $US.
Which makes the good deal and even better deal (knowing how much an ADC 9" and Curtis
cost here in Aus - over $5K in total).

When I got some Hawkers via UPS, they came in the original boxes, inside a
sealed plastic bag, inside of another box filled with plastic peanuts.
There was no problem shipping them Second Day Air.

That is why I disconnected the regen.
Regen would take the batteries to 63 volts occasionally and one transistor
would die on me.

Hi David,
Yes you seem to have missed something.
Lesley is considering buying the car and I was just giving my thoughts on
the matter.
We clearly don't work at the same rate here, I would expect to go from
driving petrol van to driving electric van in no more than 2 days, the 2
weeks was so give me plenty of time to fabricate sturdy battery mounts and
shielding the cables etc as I fully expect the finishing touched to take
longer than the real work on this.
Yes I might put in 10 hour days to do this, im like that when I get into
something and I guess unlike you I will be doing my conversion in an
engineering shop where I will be able to make anything I need, and I suppose
being able to make the parts is a skill that not everyone has.
Never mind ill let you know how long it takes when I get around to doing it,
maybe next week.
Where do you see the difference in surplus and used parts when the subject
here was actually buying a 20 year old car with an electric conversion that
was done 10 or 15 years ago and batteries that are brought second hand,
surely that is the same as buying a 15 year old second hand motor and
controller, but at least if you buy the motor and controller second hand you
can choose to put them into a newer car.
