Japan Technology / Carbon-fiber tech makes sci-fi real

A carbon-fiber car body frame made by Teijin Ltd. is lifted by two women in
Matsuyama.

The government regards technological innovation as a pillar of Japan’s
economic growth strategy, believing that technological development will give
an advantage to the nation and Japanese companies.

This is the final installment in a three-part series examining Japan’s aim
to regain its status as a manufacturing power.

A pair of women can easily lift one of the lightweight car frames on display
at an office of major textile maker Teijin Ltd. in Matsuyama.

One frame weighs only 47 kilograms. If the same frame were made of steel,
the weight would be 250 to 300 kilograms.

When a Yomiuri Shimbun reporter took an electric vehicle made with such a
frame for a test drive, its accelerating conditions were not distinguishable
from those of conventional EVs — but its braking power was surprising.

With the brake applied at a speed of 50 kilometers per hour, the wheels turn
over only a little, and the car body instantly stops.

“The braking is so strong that drivers may get whiplash,” says Yasunari
Hotani, 55, chief of the company’s Composites Innovation Center.

The experimental EV comprises a brake, suspension devices and other parts
that are usually used in mini-cars. As the body is light, the EV is more
underslung than ordinary cars. Driving it has the feel of a racing car, as
the car body hugs the road even while turning on a sharp curve.

Carbon fibers, made from petroleum or other materials, measure a few microns
in diameter. (One micron is one-1,000th of one millimeter.) A single carbon
fiber is no more than a string, the diameter of which is about one-tenth
that of a human hair.

But bundling and solidifying them with resins or other adhesives gives the
fibers strength more than 10 times that of steel. Furthermore, objects
constructed of carbon fibers are several times lighter than equivalent steel
objects.

Studies on carbon fibers began in the 1960s, and their breadth of use now
extends to military and civilian aircraft. Japanese makers, including Toray
Industries Inc. and Teijin, hold a combined share of about 60 percent of the
global market for carbon fibers.

After the United States and European countries toughened regulations on car
fuel efficiency, the development of carbon fibers for making vehicle bodies
lighter was accelerated.

Carbon fiber materials for aircraft had the disadvantage of taking a long
time to shape and then solidify with resins.

But special processing methods have enabled them to be shaped with a press
if they are heated, and mass-production has become easier as a result.

In June, the government began full-fledged efforts to assist the research
and development of nanocellulose, a fiber material, for practical use.
Nanocellulose fibers are extracted from wood fibers that are softened with
chemicals.

Nanocellulose is a little weaker than carbon fiber, but the material can be
processed into a transparent state. With nanocellulose fibers, it is
possible to make super-thin film that can bend without breaking.

Kyoto University Prof. Hiroyuki Yano, 55, says: “For Japan, which has many
forests, [nanocellulose fiber] could be a promising material. The United
States and China are also enthusiastic toward developing the material. The
next two to three years from now are the critical stage.”

Nippon Paper Industries Co. aims to begin commercial use of nanocellulose
fiber in fiscal 2016. “We sent manufacturing samples to more than 100
companies, and reactions are satisfactory,” says Masayuki Kawasaki, 53,
chief of the section in charge of the project ...

Lots of great comments on this thread.

I think it boils down to thieves steal the wire because it is easy. Nobody's 
watching, it's easy to cut the present cables, and it's easy to sell the copper 
for fast money.

So the solutions come down to a) better surveillance, b) making it harder to 
steal (harder to cut etc.), and c) making the wire less valuable (using 
something other than copper).

I thought of a 4th possibility. How about making the EVSE cord out of "shunk wire"? Include 
a plastic tube in the cable, filled with mercaptans (skunk musk)! It could also include an indelible 
dye, as used in bank money bags. Anyone who cuts one of these cables will be a "marked man", 
and never do that again! >:-)

Electric cars are Far more cost  n energy effective.

At the $200/bbl range the article so casually mentions, even unimaginably 
expensive futuristic technologies become economical -- such as using the 
Fischer-Tropsch process (or something similar) to turn atmospheric CO2 plus 
photovoltaic electricity into hydrocarbon fuels.

Of course, as is the whole point of the article, powering vehicles directly off 
of electricity is much, much cheaper than even refining today's tar sands into 
gasoline...but it's comforting, at least a bit, to know both that there're 
economic limits to how much fossil fuels we're likely to extract (because 
alternatives, expensive as they are, will be less expensive) and that we won't 
(exactly) run out of hydrocarbon fuels for things like combine harvesters and 
intercontinental aircraft -- or of hydrocarbon feedstocks for plastics.

At the same time...imagine what that doubling of fossil fuel prices and 
everything that relies on fossil fuels (like food) would be like. It's not 
going to be a pretty sight. Those with local (e.g., rooftop solar) renewable 
electricity production and electric vehicles will escape the most obvious of 
the financial hits, but even food is going to get expensive, and the global 
economy is going to suffer greatly...

...but, if we can make it past that without collapsing into chaos, a 
solar-powered future should be mighty bright indeed.

If photovoltaics become so ubiquitous, cheap and efficient that we 
could use them to convert atmospheric CO2 to hydrocarbon fuel wouldn't 
we just bypass that step and use only the electricity?  I'm pretty sure 
that the current political structure of the US will find another source 
of oil somewhere in the world. Rumor has it that Venezuela has reserves 
that exceed those once possessed by Saudi Arabia.  I really don't think 
we will run out of oil any time soon.  Energy budgeting would probably 
find that Canadian tar sands are a net loss or maybe break even.  Canada 
has run out of oil but has discovered deep natural gas.  The powers that 
want to stay entrenched have decided to put the natural gas to good use 
- making more oil.  Who cares if Alberta looks like the back side of the 
moon when they are done.
I'm thinking that the more serious shortage which will have to be 
delt with is fresh water.  The folks in Alberta may want to take note 
before they destroy this resource. The southwestern US is being affected 
by a multi-year drought of epic proportions.  It does not look like it 
is going to get better any time soon.  Will everybody have to leave the 
southwestern US when the water runs out?
We will have to start doing things that are unthinkable (but 
possible) right now.  One of those things should be water recycling.  
The technology for processing waste water has advanced quite a bit.  I'm 
told the treated water coming out of our local facility is purer than 
the water in the river it is being poured into (not hard to believe).  I 
was also shown that you could drink a glass of it without harm (somewhat 
harder to believe).  It amazes me that big cities like Los Angeles, 
Phoenix, Las Vegas, etc. would not consider this.  That would at least 
help to conserve part of the %10 of Colorado river water that goes to 
municipal water systems.

[EVDL] High Water

[Geoff Pullinger via EV]

I just saw a picture online of what I thought was a Nissan Leaf driving 
through a flood.  It made me think that electric cars could be (or are 
now) much more water resistant than ICE cars. Especially cars with AC or 
brushless motors.  Is that possible?

In order that we may get around the whole 'new battery technology'

that is not a battery.  I don't know what that would be but the whole

[Geoff Pullinger via EV]

Has there been some news story I've missed in the last few weeks?  Perhaps
something about how EV's are destroying the purity of our bodily fluids?  I
only ask this because during the last few weeks I've had three instances
where other motorists have harassed me while I was driving my EV.  One guy
in a parking lot drove his pickup straight at me while I was getting into
my car and then turned away missing me by about a foot.  The other two
incidents involved people driving on my bumper even though I was going five
mph over the limit. This has never happened to me before.  My car has EV
plates and a small sign on the back that says 'electric'.
