A South African prof came up with that alloy.
Anyway, that solves only part of the problem. Most of the work will
be figuring out how to store the energy, for overnight as well as
portable use.
If EEStor turns out to be more than just another energy scam, then
there's reason for hope.
Does Channuka apply to materials science?

Don't know :
http://en.wikipedia.org/wiki/EEstor
Turning out the items as commodities
is another difficult problem.
Including homes, offices, industrials, etc.,
transportations : cars, trucks, trains, ships, etc.
Takes a lot of time and infrastructure.
I have friends that want electric only cars, day time versus
night time availability of power is a problem for these.

The effort will make anything done during WWII look like a picnic.
But then again, most Americans weren't freezing or starving to death
during WWII so it's still possible.

Charge up one battery at home during the day and use another battery
to commute.
Better still, plug in at work while feeding the grid from your home.
But this all depends on a decent battery.
That's why EEstor is getting so much money even though most in the
field say it's unlikely if not impossible.

THIS IS PART OF THAT FUTURE THAT WAS SO HYPED IN THE 1970s
If I had been calling the shots, ther'd been an "energy war
mobilization" yesterday, 30-40 years ago.
I suppose that by now enough adaptive & influential people are now
truly serious about solar.
Depending upon the Middle East for anything other than predictable
chaos & absurdity has been ...mal-adaptive (stupid).

Nothing like an oil quagmire to focus the mind.
Depending upon the Middle East for anything other than predictable

Even if the Mideast was like Scandanavia consumption of oil would
still be a global disaster.

Stanford Report, December 18, 2007
Stanford's nanowire battery holds 10 times the charge of existing
ones
BY DAN STOBER
Stanford researchers have found a way to use silicon nanowires to
reinvent
the rechargeable lithium-ion batteries that power laptops, iPods,
video
cameras, cell phones, and countless other devices.
The new version, developed through research led by Yi Cui, assistant
professor of materials science and engineering, produces 10 times the
amount
of electricity of existing lithium-ion, known as Li-ion, batteries. A
laptop
that now runs on battery for two hours could operate for 20 hours, a
boon to
ocean-hopping business travelers.
"It's not a small improvement," Cui said. "It's a revolutionary
development."
The breakthrough is described in a paper, "High-performance lithium
battery
anodes using silicon nanowires," published online Dec. 16 in Nature
Nanotechnology, written by Cui, his graduate chemistry student Candace
Chan
and five others.
The greatly expanded storage capacity could make Li-ion batteries
attractive
to electric car manufacturers. Cui suggested that they could also be
used in
homes or offices to store electricity generated by rooftop solar
panels.
"Given the mature infrastructure behind silicon, this new technology
can be
pushed to real life quickly," Cui said.
The electrical storage capacity of a Li-ion battery is limited by how
much
lithium can be held in the battery's anode, which is typically made
of
carbon. Silicon has a much higher capacity than carbon, but also has
a
drawback.
Silicon placed in a battery swells as it absorbs positively charged
lithium
atoms during charging, then shrinks during use (i.e., when playing
your
iPod) as the lithium is drawn out of the silicon. This expand/shrink
cycle
typically causes the silicon (often in the form of particles or a thin
film)
to pulverize, degrading the performance of the battery.
Cui's battery gets around this problem with nanotechnology. The
lithium is
stored in a forest of tiny silicon nanowires, each with a diameter
one-thousandth the thickness of a sheet of paper. The nanowires
inflate four
times their normal size as they soak up lithium. But, unlike other
silicon
shapes, they do not fracture.
Research on silicon in batteries began three decades ago. Chan
explained:
"The people kind of gave up on it because the capacity wasn't high
enough
and the cycle life wasn't good enough. And it was just because of the
shape
they were using. It was just too big, and they couldn't undergo the
volume
changes."
Then, along came silicon nanowires. "We just kind of put them
together,"
Chan said.
For their experiments, Chan grew the nanowires on a stainless steel
substrate, providing an excellent electrical connection. "It was a
fantastic
moment when Candace told me it was working," Cui said.
Cui said that a patent application has been filed. He is considering
formation of a company or an agreement with a battery manufacturer.
Manufacturing the nanowire batteries would require "one or two
different
steps, but the process can certainly be scaled up," he added. "It's a
well
understood process."
Also contributing to the paper in Nature Nanotechnology were Halin
Peng and
Robert A. Huggins of Materials Science and Engineering at Stanford,
Gao Liu
of Lawrence Berkeley National Laboratory, and Kevin McIlwrath and Xiao
Feng
Zhang of the electron microscope division of Hitachi High Technologies
in
Pleasanton, Calif
Does Channuka apply to materials science?
Clearly it does.
If this means what I hope it means: Buh-byuh oil, natural gas, coal,
nuke, wood, et cetera, and don't let that proverbial door hit your
polluting toushies (assses)
This will happen.

It's getting about time for me to start jerking interest rates down so
the industry can be financed and the stuff installed ASAP.
Bernanke, I have a $150 money order made out to U. S. Courts.
It's burning a hole in my pocket.
Comprendes? If not, ask Alan. He'll explain the "extraordinary
power" of the freedom of the press.
