Rare Earth Elements

[Bret Cahill]

The pickup to my timing light is made from some kind of [ultra
brittle] rare earth element.

Is this $80/lb crap _really_ necessary?

Where is Gauss when you really need him?

China has everyone by the 'nads if we don't find an alternative.

Stop whining,. Bret.. and complain to the EPA, and the
hordes of Little Green Idiots, like yourself. It was/is you
fuck-ups who have delusions of saving the Earth, and in
the process stopped all that Rare Earth Element mining
in the USA, because of environmental concerns... and
forced the US mining companies to sell the technology
and jobs to China. Fucked yourself, Bret, you little Green
idiot... Stop complaining and cough up the dough that
now also goes to China too... AHAHahahahanson

Sure it isn't just some ordinary ceramic? Who said so, the guy who
wants to sell you a new one?

Your timing light, your call. If it was me, I'd part the damned
thing out and buy an old-school light with an iron inductive pickup.
I've never broken one of those.

There are always alternatives. Some are more... palatable than
others.

For the moment. The rare earth's make the magnetic pickup more
sensitive, so you can lower voltages and currents and use smaller
batteries and components. Make 'em sensitive enough, and they won't
need batteries at all, but power themselves off intercepted RF from
the plug wire. As an added bonus, you can use it as a TV antenna, to
watch Quincy while your face is buried under the hood of your car,
hiding from your ruthless wife.

Everybody is asking themselves the same question, and tech geniuses
somewhere are looking for an answer. What do we use to cover the gap
if the Chinese cut off our supplies completely? We've got Yankee
Ingenuity on our side, and they'd better pray we don't find one,
because there's big phat Samolians in it for all of us.

If we're really lucky, there'll be a ground war in Africa with the
Chinese for rare earths. BAD luck, that is ... Black Gold, Texas
Tea.

The rare earth metals are not that "rare"....it is known where
concentrations of these metals are located.....they are approximately
200 times more abundant then gold in the earths crust....

The rare earth metals are all quite chemically similar to each other,
and they are thus quite difficult to separate into quantities of the
pure element.

The problem is the refining of these metals....even a small amount of
contamination in the pure metal can change drastically the material
properties.....the present means of refining these metals is an
extremely "dirty" process.....and all..??....(do not know the
percentage) of refining capability is located in china....it is
estimated that it will take from 10 to 15 years to rebuild our
capability...(western world)....at one time we had this capability but
the Chinese dumped rare earths and lowered the price to where our mines
and refineries were shut down as being uneconomical....

just some thoughts....have fun.....sno

here's from an article -- sorry, about the format:

The
Mountain
Pass
mine,
located
in
the
Mojave
Desert
north
of
Barstow,
California,
was
one
of
the
richest,
if
not
the
richest
rare
earth
element
(lanthanide)
mine
in
the
world.
But
on
Oct.
31,
1994,
with
the
passing
of
the
California
Desert
Protection
Act,
the
mine
was
effectively
surrounded
by
park
land,
potentially
locking
up
a
large
part
of
the
ore
body
in
the
new
Mojave
preserve
and
adding
tremendous
constraints
to
the
open
pits
operation.
This
act
was
pushed
through
by
Sen.
Diane
Feinstein
and
Rep.
George
Miller.
When
water
from
a
routine
flushing
of
the
tailing
pipeline
accidentally
spilled
into
the
Mojave
preserve,
the
clean-­‐up
effort
by
the
owner,
Molycorp
Minerals
LLC,
was
delayed
for
months
by
Federal
agencies.
Twenty-­‐nine
government
agencies
got
involved.
U.S.
Fish
and
Wildlife
and
California
Department
of
Fish
and
Game
SWAT
teams
seized
the
company
computers
and
records
at
gunpoint.
They
held
the
employees
incommunicado
under
armed
guard,
denying
them
access
to
the
company
attorneys,
who
were
held
outside
at
the
main
gate.
These
federal
agencies
levied
more
than
$6
million
in
fines
and
penalties
against
the
company.
This
includes
$1
million
for
a
dead
desert
tortoise
that
was
found
on
the
property.
(!)
An
autopsy
on
the
tortoise
failed
to
show
any
wrongdoing
on
the
part
of
the
company.
As
it
turns
out,
Diane
Feinstein's
husband,
Richard

China has everyone by the 'nads if we don't find an alternative.

Electric cars are an alternative.

You could invade China as you did with Iraq. You wouldn't even need to
lie. You could say China conquered Tibet and you are liberating it.

The US wants to get paid in full for the sale of Taiwan first.

That money won't help much anyway, a BILLION dollars a day in loans from
China would take forever to pay back even after the betrayal of the Island.

Electric cars are an alternative.

The alternative is 0.1 kW/kg power density electric motors that "only"
weigh 220 lbs.

If you want to scoot through intersections you rig up a big spring
that can be wound up while waiting at stop lights.

If you want to haul a boat up a mountain you rent a diesel truck.

is that how they got Noah's ark, up there?

http://www.21stcenturysciencetech.com/

Orville Wright at 34 (left)
Wilbur Wright at 38 (right)

The difficulties which obstruct the pathway to success in flying
machine construction are of three general classes:

(1) Those which relate to the construction of the sustaining wings;
(2) Those which relate to the generation and application of the power
required to drive the machine through the air; and (3) Those relating
to the balance and steering of the machine after it is actually in
flight.1

Although the breakthrough achieved by the brothers would be in the
solution to the third problem addressed by Wilbur—the problem of
stability and control in powered flight—they would also considerably
advance the knowledge in the other two areas, as well, in the march to
their great achievement.

Didn't they also discover the principle of the propeller with the
pitch gradient along its length?

See mikey China and the rest of the world use a different billion than the
USA does but you already know everything since your 12th birthday, don't

You mean the angle of attack decreasing radially?

That may go back to props on steam ships. Axial flow steam turbines
had also been around a long time.

Now that we're completely off topic the prop on those 25 mph motor
para gliders is only 3 1/2' in diameter so the wind speed must be
pretty high to get enough thrust. 50 mph exhaust velocity would give
maximum propulsion efficiency.

They're trying to go to batteries & electric motors and a bigger prop.
might help. The basket or cage would need to be larger to accomodate
it.

Now they can get the entire thing into a mini van or pu.
