I need an inverter that will power a 10 horse AC
208/230v 60Hz (3) phase motor. 27.8 peak amps. 3500
rpm. with 12v deep cycle batteries. Any advice
appreciated.

Hello Ken,
I seen these batteries at Sam's. They have two types of orbital by Exide. One
is a 1000 amp cranking, good for only engine starting. The other is a deep
cycle marine type which is 50 AH. The deep cycle would only get me only 8
miles at 50% discharge, which I would have to charge every day. Would last me
a year or two.

Subject: Orbital batteries at Sam's Club
I was recently in Sam's Club and saw an orbital
battery on the shelf:

I understand Exide makes their batteries, so it's
likely a relabled version of one of these:

Anyone know anything about them? Would either be a

My understanding is that 3 phase motors are unsuitable for EV's. They work
best(only?) running at a constant RPM so unless you have some kind of advanced
CVT, I don't think it's going to work for you. They have very little starting
torque and would be inefficient and weak running slower than their target RPM.
I could be wrong - I'm not an expert, but I too have considered using 3 phase
motors. The only way I could think of making it work would be to use a
complicated custom inverter that modified it's phase to the motors rpm, like a
big servo controller.

I understand Exide makes their batteries, so it's
likely a relabled version of one of these:
While Exide sells the Orbital, they neither designed or built it
until they bought the factory that made them in Spain.
Exide is a rather low life company and the Orbital is the only
batt from them I would use. But sooner or later, Exide will get their grubby
hands on them and make them cheaper quality wise.
Exide was so bad the Exc's of the company went to jail over product
fraud, something that rarely happens.
And Walmart makes companies cut corners for lower costs, so many of
their products sold at Walmart, Sam's Club are inferior to the same brand sold
elsewhere.
You just don't save enough there to be worth buying from them.
Better to find a distrubutor for lower prices. With the number of batts EV's
need, ususally you can get a good break on the price in other places. There
are several places here in Tampa that sell Trojan, other batts for prices less
than Sam's Club, Walmart so they don't even have the lowest prices if you
seriously compare them. So support your local battery prople !! The service,
help you get will be worth it.

I'm helping Bill with his conversion 72v bug and it seems the Sevcon will
work at 70vdc. How nice. I thought it was a 120 to 128 device but happily
it seems to have a low brown out point. It was putting out 14.2vdc. Is
there a bad side to undervolting a device? LR......

Hi Travis and all,
Yes, I got the pictures, but as believe I said in an email, that was
when were having problems with the submission form so I got no
specs. I think you sent me the specs but that and the emails went
with my hard drive disaster. I still have the pictures, if you could
try another shot at the submission form so I can get started then I
can get your page going.
FWIW, I also have 25 more completed pages from other folks who never
got back to me to approved their Album page. I kind of gets to be a
drag to make up an Album page and then it never gets used.
Thanks,

of those cards was from the producer of globe trekker, asking if
they could film me with my car. not one to pass up a chance to
talk about EVs, I agreed. They set it up so that the traveller,
whose name I forget, would happen by as I was plugging in, and we
chatted for a few minutes. They culled that down, but still, I
think it was pretty good exposure. I've had people stop me in the

Someday I'll get organized and have a handout with information
about the car and put it on the side of the car like those real

great, not just because I get free parking and charging while at
work, but they are very prominent, so lot's of people notice. I'm
sure Rick, who parks in the other spot here (with that Ford Escort

Riding around in our Jeep Cherokee, I was thinking of a way to mount
the batteries under the vehicle(to keep the interior usable and
functional).
Mounting AGM's to the floor upside down, a good amount could be
mounted to the vehicle. Several rows of 3 or 4 between the drive
shaft tunnel and frame rail. Not to mention a good number where the
gas tank was.
One drawback to having them upside down is if a terminal loosens, it
drops to the ground. Solution? Drill a hole through the terminal and
post and put a cotter pin through it!
The Jeep would lose some ground clearance, but would have a good
center of gravity(low). This would work good on any truck or SUV if
it's high enough off the ground stock to allow for this. Or raise the
vehicle slightly potential.
The battery racks could be made of angle iron(what else?), and be made
in such a way that the batteries could be slid in and removed from the
side and the final locking bar or corner be installed to keep them in
place.
I think I'd bolt the rack to the floor instead of welding it. The
weld could tear through. If bolted, I'd use a piece of flat stock on
the top side to prevent the bolts from pulling though. Would it be
better to make several racks vs's making one big one on each side?
Something about the total amount of weight being hung vs's if it was
split up?
Do you see any potential problems with the batteries being mounted
underneath the vehicle and being upside down(cotter pinned terminals)?

Ryan,
Good luck with the tower, there will always be people
that will tell you you are crazy. Ignore them and GO
for it!
Just to clarify...
""In fact no one is really clear on how that tower was
supposed to work.
Its intended workings were not completed nor were they
well documented,
contemporary and modern engineers haven't been able to
make sense of
the
purpose of its shape, and it was demolished in 1917.""
The tower itself is no mystery, it is explained in
DETAIL in Nicolas patent number 1,119,732. Simply, it
is designed for the transmission of energy without
wires. If you read Nicola's patent no.1,266175 some
additional info on the shape of the top of the tower
is explained. I am an Engineer and I understand how
it worked and have a good idea as to why it was
destroyed.
"" Especially coming from these "I
have seen government laser satellites are controlling
the weather"
folks.""
For anyone that would like to know if weather control
is true or just some looney bloviating, they should
read Patent number 4,686,605 (column 13). Not every
transmission station requires an oil well as the
energy source to power the 3.5 Million Watts needed to
operate this one (fig 5).

Let me know how it works out.

Also consider the size, weight, range, and cost of lead and lithium
vs's the size, weight, range, and cost of a hydrogen fuel cell and the
storage tank. Also the cost of electricity vs's the cost of hydrogen
and it's availability. How much of that stuff is currently being made
and could enough be made to supplement all the gal per day of gasoline
currently being used?
What I like about battery power is that we can build and drive these
vehicles TODAY. Can the same be said about a hydrogen fuel cell? If
you can get Ballard or someone to sell you one, or can buy the
components and make one; here's a place that very well has a location
in your city that you can buy hydrogen from(could even have it
delivered or rent a hydrogen generator from them too!):
http://www.airgas.com/browse/product_list.aspx?catID=195&WT.svl=195
http://www.airgas.com/content/products.aspx?id=9002015000000
How many miles per gal/lb on that stuff? How much $$ per gal or lb?
How much electricity does the home generator consume vs's a battery
charger? Look at the electrical requirements for the generator near
the bottom of the page!
http://www.airgas.com/content/products.aspx?id=9002015000000
One could get a hydrogen generator, then you need a storage tank and a
hefty pump to refill your tank. And if you run out far from home and
not near an Airgas distributor... it's not like limping over to the
nearest power outlet(that are pretty much anywhere any structure is).
Though if either bat or cell vehicle has high enough range, getting
stranded sort of becomes a non issue. Big difference between 40 mile
range and ~150..
(I was at 7/11 airing up some tires on a vehicle I don't own and at
the base of the air pump was an electrical outlet!)(I also saw an
outlet on the little Taco Bell sign in their landscaping.)(I'm going
to take a picture of the most bizarre display of outdoor electrical
outlets I've ever seen. Our local library has this cluster of about
10 or 15 young trees and each one has an electrical outlet at or near
it's base!?! Why?)

What sort of gearing or transmission would you (or others) recommend? I
really only need reliable 50 - 55 mph. And, offered either one, I assume you
would recommend I take the hydraulics motor rather than the monster drive
motor?

Yes. Upside down is bad for any AGM, for a number of reasons.
On many AGMs, the cells share a common air space over them. The cell
interconnection jumpers and safety vents are in this space as well. Normally,
when the battery gasses, the gas collects in the space. If it vents, it will
vent gas (not electrolyte).
If you mount it upside down, then when it gasses, the gas bubbles collect at
the bottom. Gas pressure can force the electrolyte out of the glass mat, and
into the top space. The electrolyte shorts the cells by contacting two or
more interconnection jumpers, and if the pressure gets high enough to open
the vents, it dumps electrolyte instead of gas.
I think with a little creative thought, you can still mount the batteries
right side up under the vehicle.

Well it had been an exciting day up to this point but when I looked at my e
meter I had pulled 85 ah form my 25 6v golf cart pack , 10 miles form home ,
and the
mower was empty. The 2 yards I had left to do I hadn't ever ask about
charging there as most of the time nobody was there . I wasn't far from a yard
and house I'm look after while the owner was selling it , and across the
street
is another costumer that wanted me to fix a door and other odds and ends. So
I plugged the truck in to the dryer out let and start pumping 30 amp into the
truck
,then plugged the mower into a 120 out side out let , and turned the pfc 50
to about 23 amp , ( thinking the 72v at 23 would need about 15 amp @ 120 .
Sure is nice when you can get to the barker box , . So next door I go and by
the time I had fixed
this lady's door , changed a few light bulbs ,and had a few cookies my
truck was at - 50 and the mower was charged. Now the house that I'm plugged
into , has been sold so my nice 240 out lit there in the middle of 3 yards
is not going to be available . As I'm talking to my customer who I've been
mowing her grass for around 20 years , at the same price , I bring up the
fact the now that her neighbor has sold there house and now with my electric
mower I would really need to be ablr to plug in to her dryer out let , .
She is probable over 80 now ,snd lives alone . She always has little things for
me to do after I cut the lawn
, I don't mind but If my truck was plugged in pumping amp , I'd feel allot
better , . I offer to give her 4 times the money that the electric cost her
and tried to make a joke about how she could start her own ev gas station.
She gives me the song and dance about how she has to watch every penny and
on a fixed income . "How would you know how much electric it used" . I told
her about the meter it the truck , but could sense this was not going to
happen . Somebody should write a short paper on all the benefits that a
person or business would get from letting an electric car/truck driver plug
in .
1 the gas I don't use you can
2 while I'm plugged into your outlet , I won't be in a hurry to leave and
will be looking for thing to do for you
3 you will be doing something to help decrease our dependence on oil.
4 make a little money
I would say about 10% of my customers feel this way , no plugging in under
any conditions. Its really no big deal , as I can find someplace and if not
I can always just drive slow .
I'm off to the next 2 and its getting late . When I get there , the owner is
there , a working guy , paying about twice what the old lady was and I start
talking to him about my new electric mower , . He comes out to see it ,
thinks its way cool , tells me about all the people he's told about my
electric truck but this , woooo this is really cool , . I fire it up , spin
the blades , wooooo , . I then tell him about the extra juice it takes form
my truck and if there is a out let I might use when I mow his and the
neighbors yard . "Sure , this is a old house and there aren't any outside
outlets out side but you can get into my garage through the back door." A nice
dryer
outlet is there waiting for me , and with 2 yards next to each other ,
another ace in the hole for me. He laughed when I offered him money .
I know I must sound like a newbee , and I really feel like one again , When
I read some of the stories people write just after they start driving their
ev's I can feel the excitement and I wonder if people sitting on the
edge after reading some posts don't then make the EV jump . ,
part 3 more batteries ...

I would mount the batteries so the terminals were pointing to the side so
that they would be less susceptible to stone damage.
Yes, I believe it is possible to build the racks so the batteries slide in
from the side. You can retain them with a strap around the battery posts.
When you bolt the racks to the pan, you should use round plates similar to
seat belt attachments
(http://www.pegasusautoracing.com/bigpicture.asp?RecId=629) because the
corners of square backup steel tends to crack the pan.

no 3 was just around the corner
and I was at -10 ah when I pulled up to it . Another easy one and I was
at -25 ah when done ( used 15 ah again ) . The neighbor was working in the
back dealing with some hurricane clean up and I stopped and asked if he
wanted me to grind up that pile he was working on , "ya , please" .. The
electric made short work of the pile and of course he was blown away by
the whole thing .
to be continued ,
Steve clunn
Well it had been an exciting day up to this point but when I looked at my e
meter I had pulled 85 ah form my pack , an 10 miles form home , and the
mower was empty. The 2 yards I had left to do I hadn't ever ask about
charging and most of the time nobody was there . I wasn't far form a yard
and house I look after while the owner is up north, and across the street
is another costumer that wanted me to fix a door and other odds and ends. So
I plugged the truck in to the dryer out let , pumping 30 amp into the truck
, and plugged the mower into a 120 out side out let , and turned the pfc 50
to about 23 amp , ( thinking the 72v at 23 would need about 15 amp @ 120 .
Sure is nice when you can get to the barker box , . By the time I had fixed
this lady's door and changed a few light bulbs ,and had a few cookies my
truck was at - 50 and the mower was charged. Now the house that I'm plugged
into , has been sold so my nice 240 out lit there in the middle of 3 yards
is not going to be available . As I'm talking to my customer who I've been
mowing her grass for around 20 years , at the same price , I bring up the
fact the now that her neighbor has sold there house and now with my electric
mower I would really need to be about to plug in to her dryer out let , .
She is probable over 80 now , her husband died about 10 years ago , and
lives along . She always has little things for me to do after I cut the lawn
, I don't mind but If my truck was plugged in pumping amp , I'd feel allot
better , . I offer to give her 4 times the money that the electric cost her
and tried to make a joke about how she could start her own ev gas station.
She gives me the song and dance about how she has to watch every penny and
on a fixed income . "How would you know how much electric it used" . I told
her about the meter it the truck , but could sense this was not going to
happen . Somebody should write a short paper on all the benefits that a
person , business would get from letting an electric car/truck driver plug
in .
1 the gas I don't use you can
2 while I'm plugged into your outlet , I won't be in a hurry to leave and
will be looking for thing to do for you
3 you will be doing something to help decrease our dependence on oil.
4 make a little money
I would say about 10% of my customers feel this way , no plugging in under
any conditions. Its really no big deal , as I can find someplace and if not
I can always just drive slow .
I'm off to the next 2 and its getting late . When I get there , the owner is
there , a working guy , paying about twice what the old lady was and I start
talking to him about my new electric mower , . He comes out to see it ,
thinks its way cool , tells me about all the people he's told about my
electric truck but this , woooo this is really cool , . I fire it up , spin
the blades , wooooo , . I then tell him about the extra juice it takes form
my truck and if there is a out let I might use will I mow his and the
neighbors yard . "Sure , this is a old house and there aren't any outside
outlets but you can get into my garage through the back door." A nice dryer
outlet is there waiting for me , and with 2 yards next to each other ,
another ace in the hole for me. He laughed when I offered him money .
I know I must sound like a newbee , and I really feel like one again , When
I read some of the stories people write just after they start driving there
ev's I can feel the excitement and I often wonder if people sitting on the
edge after reading some posts don't then make the EV jump . , but maybe its
just me. If all this seems long and boring , well then don't read part 3 .
got to go ride that mower !

Jody,
As I recall, I picked up a small 12V SLA battery for my electric
bike from Batteries Plus with that name on it (and could not find any
specs on the internet when looking for WERKER). I'd suggest looking on
the label to see if there is a secondary supplier (e.g. US Battery or
Trojan). I do know that Batteries Plus re-labels their Trojan-supplied
6V's.

Subject: WERKER batteries
I was down at the local Batteries+ store in Virginia Beach buying a new
battery for my motorcycle and noticed they had golf cart batteries with
a
brand name of WERKER. They looked just like US2200s but were gray. Has
anyone ever heard of these? They were selling a 215 Ah battery for $70
on
the shelf. I anticipate that if I were to buy 26 I could get a much
better
price.

I'm sure most of the e-bayers have already taken note of the above. For
those wanting the appliance version (and who have a lot of spare cash), here is
your opportunity. Not much more I can say about it. I've have the privilege
of
seeing one of these up close, but never actually driven one. From what I
have heard, they are super nice, but come with ~$40,000 price tag.
For those more in my price range, we have the following 1981 VW pickup
Electric Vehicle, No Gas, No Emission, truck, Volkswagen
Item number: 4588481121
That could be a good starter vehicle for someone.
There is also the
1981 Ford : Escort 3 dr htchbk
Item number: 4588022473
If you happen to be in Chicago, you can save on transport, but the price (In
my opinion) is much too high.

Hey Jimmy,
You do realize that these days the Patent Office will patent almost
anything (as long as it's not already patented).
Just because someone took out a patent on an idea doesn't prove that the
idea works. In fact there are thousands of patents on ideas that not only
don't work, but can't work.
For example, the Patent Office has a long standing policy on NOT patenting
perpetual motion machines. However, they are quite willing to patent
over-unity machines. The difference, of course, is that an over-unity
machine not only runs for ever, it produces excess power while doing so.

There are at least two different Sevcon models ( they look the same except
for the label on the bottom).
I have one labled "72/96 V" that works down to about 60V, and one labled
"128V" that works down to about 80V. Which model are you talking about?

I'm helping Bill with his conversion 72v bug and it seems the Sevcon will
work at 70vdc. How nice. I thought it was a 120 to 128 device but happily
it seems to have a low brown out point. It was putting out 14.2vdc. Is
there a bad side to undervolting a device? LR......

Allan,
There are tons of studies of the type you are looking
for (comparing fuel pathway efficiency and/or
emissions for various vehicle and fuel types). A lot
of them are carried out using the GREET model
developed by the DOE at Argonne National Labs.
For example, see the fifth slide of this presentation
:
http://www.transportation.anl.gov/pdfs/AF/270.pdf
it shows the Well-to-wheels GHG emissions for various
fuel pathways and vehicle types. According to this
model, a fuel cell vehicle fueled by H2 made from
reforming natural gas creates less GHG than an EV
charged from the US mix. On the other hand, a Fuel
cell vehicle fueled by H2 made from electrolysis using
the US mix is even less clean.
if you are interested in other studies (not all of
them include EV's though), there are lots of
publications listed here :
http://www.transportation.anl.gov/software/GREET/publications.html
hope that helps,
