Subject: NPR sound clip of the day
I was listening to NPR (National Public Radio) Monday night, and heard a
program called sound clips. I thought, "How cool would it be if those of you,
my car isn't working at this point :( , who drive EVs daily submitted the sound
of their EVs." In describing why this is such a great sound you could mention
a myriad of things. What publicity if they play the sound. It would be cool
to be able to hear the sound of a contactor controller, the whine of the
Curtis, and the silence of the Zilla. Just a thought.

I am gathering that by "DCP controller," you mean the
old 600 series.
They may turn up here or there; personally I'd aim for
the ($2400) 1200A version. Between more power, and
better reliability, I think you'll be happier with the
end result. Peter has been known to rebuild the old
ones, but I think he's moving away from that.

Once the synchromech is trashed, you will feel differently. On my car
upshifting works okay, but downshifting is dicey at best. The car has
no flywheel, and only a tiny 6.7" ADC motor.

U.S. puts squeeze on Iran's oil fields
LATIMES
A campaign to dry up financing for projects poses a threat to
Tehran's ability to maintain exports, analysts say.
By Kim Murphy
Times Staff Writer
12:18 AM PST, January 7, 2007
LONDON As Washington wages a very public battle against Iran's
quest for nuclear power, it is quietly gaining ground on another
energy front: the oil fields that are the Islamic Republic's
lifeblood.
Iran's oil industry has raked in record amounts of cash during three
years of high oil prices. But a new U.S. campaign to dry up financing
for oil and natural gas development poses a threat to the republic's
ability to continue exporting oil over the next two decades, many
analysts say.
The campaign comes at a moment of unique vulnerability for Iran's oil
industry, which also faces challenges from rising domestic energy
consumption, international isolation, a populist spending spree by
President Mahmoud Ahmadinejad and trouble closing contracts with
foreign oil companies a recipe for potential disaster in a nation
with one of the world's largest reservoirs of oil.
"If the government does not control the consumption of oil products
in Iran
and at the same time, if the projects for increasing the
capacity of the oil and protection of the oil wells will not happen,
within 10 years, there will not be any oil for export," Mohammed Hadi
Nejad-Hosseinian, Iran's deputy oil minister for international
affairs, said in a telephone interview.
If Iran were to suddenly stop exporting its 2.6 million barrels of
oil a day, such as in the event of a military strike, world oil
prices probably would skyrocket. But a gradual decline might be
offset by other OPEC members, analysts say, particularly as Iraq
increases its oil production and Saudi Arabia carries out plans for
significant increases in its production capacity.
The efforts by the United States and its allies over the last few
months to persuade international banks and oil companies to pull out
of Iran threaten dozens of projects, including development of Iran's
two massive new oil fields that could expand output by 800,000
barrels a day over the next four years.
"Many European banks which had accepted financing some oil industries
projects have recently canceled them," Nejad-Hosseinian said.
In addition, banks are no longer granting letters of credit for
delivery of some supplies, ministry officials say. And as nations
such as Japan begin to back out of Iran oil development under U.S.
pressure, the government in Tehran is being forced to dig into its
own reserve funds to get crucial new projects off the ground.
But Nejad-Hosseinian said Iran had recognized the gravity of the
threat and launched steps to head it off, including new "smart"
rationing cards, scheduled for distribution in March to check
skyrocketing sales of cheap gasoline, and an overhaul of Iran's
historically stingy contract terms in an attempt to lure big oil
companies into skirting the U.S. roadblocks.
Iran also is hoping to turn to China and Russia for help. But U.S.
officials already have warned that they will seek to hold China
accountable under Washington's unilateral sanctions laws if it
proceeds with a $16-billion project to develop Iran's North Pars gas
field. China also has signed a memorandum of understanding under
which it may take on development of the Yadavaran field in
southwestern Iran, expected to boost production by 300,000 barrels a
day.
Domestic problems
Iran's oil and natural-gas dilemma has no direct connection with the
sanctions adopted last month by the United Nations Security Council,
which are narrowly aimed at assistance to Iran's nuclear program.
Although Tehran insists it has strictly peaceful intentions, the U.S.
and others believe the program is linked to development of nuclear
weapons.
Rather, the looming crisis stems from a series of domestic problems
that have converged at a time when Iran is susceptible to U.S.
attempts to capitalize on them to coerce Tehran's compliance on the
nuclear issue.
First is the condition of Iran's aging oil fields, which have never
fully recovered from damage inflicted during the Iran-Iraq war of the
1980s.
To maintain sufficient pressure to keep them pumping, Iran has to
divert large amounts of natural gas that might otherwise be sold.
"You need billions of dollars invested in order to stand still to
avoid a decline," said Manouchehr Takin, a former Iranian petroleum
geologist who is a senior analyst for the Center for Global Energy
Studies in London.
Likewise, increased output from refinery construction is being
outpaced by the swelling number of young Iranians with a fondness for
gas-guzzling cars. Heavily subsidized gasoline is just 35 cents a
gallon, a price that invites smuggling, and talk about raising the
price has, until recently, gone nowhere.
Moreover, the country has one of the most extensive residential
heating infrastructures in the world, with homes in the most remote
villages warmed toastily with cheap natural gas.
Total domestic energy subsidies total $20 billion to $30 billion a
year, Takin said.
"These subsidies are now costing the government roughly 15% of Iran's
GDP. That should knock you over. That's a mind-boggling number," said
Hossein Askari, professor of international business at George
Washington University. "And the nub of the problem is that if you
were to cut the subsidies, I think there would be riots in the
streets."
Iran could be reinvesting in the oil and gas infrastructure, and it
is to a degree, but Ahmadinejad also has diverted billions of dollars
in oil revenue to social welfare programs, major infrastructure
building programs in neighboring countries such as Afghanistan and
importation of consumer products to the consternation of many of
those in his government.
Foreign investment
The heavy lifting in recent years has been left to foreign oil
companies, which in the 1990s began working in Iran in substantial
numbers for the first time since the Islamic Revolution.
U.S. sanctions in place since the seizure of the American Embassy in
Tehran in 1979 have prevented U.S.-based oil companies from operating
in Iran, but companies such as Royal Dutch Shell, France's Total and
Italy's Eni have invested, some heavily, despite on-again, off-again
threats by Washington to pursue sanctions against foreign companies
under U.S. laws.
To a great degree, though, Iran has created its own woes by dragging
out contract negotiations and offering only skimpy paybacks to
foreign oil companies interested in building new production, industry
analysts say.
"People have said that even with sanctions and all the rest, if
Iranians want investment in their oil industry, what they need to do
is offer decent terms, and whatever the sanctions, they would have
companies flooding in," said one Western oil company official, who
spoke on condition of anonymity.
"But the issue for us at this point is both political and commercial.
The state of the country is such that it's just not the right time to
be there."
That is the message Washington is trying to reinforce. For years,
U.S. sanctions prohibited investments of more than $20 million in
Iran's oil industry, but in practice, they were applied only to U.S.-
based oil companies. But as the nuclear showdown has unfolded, and as
it became clear the U.N. sanctions would not impose serious economic
penalties on Iran, Bush administration officials decided on a
different tack.
Envoys from the Treasury Department have approached international
banks and companies, reminding them of Iran's record of financing
militant Islamic organizations such as Hamas, in the Palestinian
territories, and Hezbollah, in Lebanon, through the banking system
and its defiance of U.N. resolutions on nonproliferation, and warning
that investing in such a country may not be a good business risk.
Simultaneously, the Justice Department reportedly has opened
investigations of several banks to determine whether investments in
Iran violated U.S. sanctions laws. In late 2005, Dutch bank ABN Amro
agreed to pay $80 million in fines stemming in part from improper
transactions with Iran through its subsidiary in Dubai, United Arab
Emirates.
UBS Bank and Credit Suisse of Switzerland recently announced they
were suspending most new business with Iran, and British-based HSBC
said it would no longer accept dollar transactions from within Iran.
"Banks are constantly doing risk assessments about what kind of
business they want to be involved in," Stuart Levey, Treasury
undersecretary for terrorism and financial intelligence, said in a
telephone interview.
"There's a lot out there suggesting that there's an element of
coercion involved. But I think that for a lot of these executives,
the main thing driving them is they really don't want to be involved
in facilitating terrorism or proliferation or any other crime."
More than two decades of U.S. sanctions have had little effect on
Iran's oil industry U.S.-based companies have been replaced,
largely by Europeans. But this new attack on financing has rapidly
started to dry up potential loans on dozens of projects, according to
oil industry insiders in Tehran and the West.
One of them is reportedly the giant Azadegan oil field in
southwestern Iran near the Iraqi border. Japan's INPEX Holdings Inc.
in October pulled out of all but a 10% stake in the $2-billion
project under U.S. pressure, and alternative financing from foreign
banks has failed to materialize, said one source with close
connections to the Iranian Oil Ministry.
"It has been very effective. Nobody is prepared to loan Iran anything
on anything," said Fereidun Fesharaki, an energy advisor to the
Iranian prime minister in the 1970s who now heads the FACTS Inc.
petroleum consulting firm in Honolulu.
In a report published this month by the National Academy of Sciences,
Johns Hopkins University geography professor Roger Stern argued that
the confluence of high domestic demand, a delay in adding production
capacity, the diversion of natural gas to keep wells producing and
other factors could lead to a decline of 33% to 46% in Iran's exports
by 2011 and a halt to exports by 2015 or so.
Other analysts have said those forecasts are too dismal, and output
is more likely to remain flat at about 4 million barrels a day.
Iranian officials say they have signed $28.4 billion worth of new oil
and gas development contracts over the last 15 months, and hope to
increase production to 7 million barrels a day by 2014 a goal that
the International Energy Agency says will require $80 billion in
investments.
The nuclear issue
Whether that will be realized could depend, in large part, on what
happens on the nuclear issue.
In fact, Iran's oil and gas dilemma appears to point up a "genuine"
need for civilian nuclear power, Stern said.
"When I first started hearing this claim that Iran needed these
nuclear plans to substitute for oil and gas, I thought, 'That's
ridiculous,' " he said. "So it has really been a surprise to me," he
added, to see evidence that Tehran's stated purpose for the nuclear
reactor is not "simply a weapons deception."
"I don't think they're nice guys," he said. "This is a regime that
funds terrorism and is making outrageous claims that Israel should
disappear. But it just happens to be a convenient truth for them that
they do need nuclear power."

I was researching the history of GM buying up cities' electric rail
systems, and happened on a post on the C-Car yahoo group from our old
pal Neon John stating that this was politics (maybe so) and smacked of
*conspiracy theory* (!), and that he could refute the argument with
facts. All I could think of when I read this was those who state they
can prove the Holocaust didn't happen... Sorry if that sounds
political, but it's public record that the judge gave them a slap on
the wrist, so a past history like this make me doubt anything said by
GM (or most any other car company) until it can be seen, touched,
driven, AND purchased!

Right on Rod! Get at least two copies, one for yur local library,
donate it. I'm gunna put a note and fone no inside saying if you are

Yes very very true Roland. When my SOC of the SCS225's reach 70% the voltage
sags like anything. And it becomes difficult to keep up with 60 km/hr
traffic. If its a flat road no problem. but those large current discharges
really take a toll out of them. My batteries are totally stuffed now. I have
driven approx 2500 km on them and they don't seem 100% anymore. Partly
becomes i abused them like mad. I didn't run them in. I totally discharged
them the first time i got my car on the road. And i didn't use a spcial
charger, just brute transformer power.
They are now only good for RAPS.
Can't wait till i install those orbitals in my car for 120 volts. Woooho!

That is correct with the SCS225's. They are closer to a cranking type of

Reserve capacity of 225 minutes at 25 amps.
A 6 volt will have up to Reserve capacity of 540 minutes at 25 amps or 145
minutes at 75 amps. The SCS225 reserve capacity is reduce by about 4 to 1
for 75 amps which is closer to a EV average load.
225 minutes/4 = 58.25 mins.
56.25 mins /60 mins - 0.93 hour
93 hr x 75 amps = 70 ampere-hour
A 6 volt T-145 has a reserve capacity of 145 minutes at 75 amp which
reduces
the usable ampere-hour to 181 ah. I am running very low low ratios like
about 20:1, so I can hold this to 40 amps.
My accessory battery is a SCS 225 which must be keep above 70% SOS at all
times. If it was a standard cranking battery, it would have to be at
least
80% SOS.
One time I let the SCS 225 discharge to about 55% SOS which is about 10.5
volts. When it reaches that voltage, it will drop very quickly in with
seconds to as low as 4 to 6 volts.

G'day All
I've been discussing off-list with Don regarding what he has and intends.
He has a VW Beetle that he is making into an EV. He has wrecked a forklift
to get donor parts from, and (at least initially) wants to use as much as
possible from the fork as donor parts. Don can take photos to send if
anyone needs them for meaningful discussion.
Motors (Hey, Jim, listening?):
He has a pair of prestolite series motors, 6.7" diameter with two-bolt
(short) fields. They are double ended motors with an 1 3/8th" helical
spline one end and a 15/16" straight spline the other (this originally had
a brake fitted on it). Advice on simplest method to install dual motors
into the beetle will be appreciated, along with what to do to give the
motors the best chance. I feel one of these motors would not be enough in
the beetle, but others may disagree.
Controller:
He has an EV1, 24 to 48 volt with a Oscillator ASM 1C36450SC IH3 BR. Has
anyone got a higher voltage one he can have for a minimal price, or
alternatively where he would get one from?
Contactors:
From the fork, two in series should be safe at higher voltage (up to double).
Performance:
With the two Prestolites and the EV1, his performance will be not great. If
he runs a 48 volt pack, I'm guessing NEV-like performance, but has anyone
got any idea what it really would be? He'd like to go to 72 or 96 volts if
he can get a suitable oscillator card for the EV-1, anyone got an
understanding of what that would provide for performance?
Thanks. Don has asked me, but this is outside my experience.
Regards
[Technik] James

This is why EV's are not available. We need EV's
that not only match ICE's, but beat them handily like the
Tesla does in the high $ range market!!!
And there is no reason why EV's can't if designed,
built right as EV's.
When I talk about mine, I always include my fuel
costs of $.01/mile and the cost equivilent of 240mpg!! That
really gets their attention, then they find out it will do
80 mph and over 100 mile range too, they get really
interested.
When they find it costs just $13k, they start asking
when can they buy one!!
What we need are great EV's we can brag about that
are cost effective, have good performance. EV's can easily
be competitive with ICE's when all costs, either money,
enviroment, national ecomomy, security reasons are
considered.
Regretfuly conversions are never going to do this in
most peoples eyes as they don't consider the last points, it
has to be EV's built from scratch to get the performance
needed to compete directly.
BTW I rented my new factory yesterday, move in after
the BBB,

Hi Matt and All,
Riblets designed from shark skin do work in water
and aircraft at high mach numbers but not for cars at car
speeds.
It dies it by as said before, making a layer of
slow air next to the skin to lubicate the air above it to
keep it attached.
A golf ball does another trick which is the bumps
are meant to seperate the air from the rear of the ball as
it flys before they turn into diverging vortex's by allowing
the air to seperate just after the widest point.
Air drag is how much air an object drags,
accelerates with it as it moves. If the object parts the air
and lets it come back together close behind it, has the
lowest drag. objects that trun the air behind them quickly,
turn the air into diverging vortex's which spread out,
dragging, accelerating a lot of air behind it and that takes
energy, a lot of it!!
The best place from vortex generators is where the
rear of the EV as starts to turn sharply inward of more the
17deg, I like 13deg because reality, put the generators just
before this angle so the air can seperate cleanly before the
diverging vortexes are created. The air will then converge
somewhere behind it in an aerodynamic cone, greatly lowering
drag.
You could put yarn taped to just before the rear
and drive, will tell you just where the air turns to
diverging vortex's.
If the Scion is the boxy one, the rear isn't your
aero problem, the upright windshield is. You can help this
by using a airfoil over it that turns the air from going up
to going aft like what some trucks use, though need a good
gap, 4-6 above the roof, curving down forward shape. When
you do this the air will form a bubble in front of it to
fair the front would help the most. But not a good higher
speed EV starting point. The Sedan version looks good
though.

On one of the other videos from the same people they say the motors
come from EV Tech and are available in front and rear configuration,
and seem to be geared internally and also have a freewheel mechanism.
