What we really need is a device, perhaps nanobots or a miniature black-hole (or
a combination of the two), which is fed garbage and it spits out elemental
matter. Then there'd be no resource shortage ever... only an energy shortage.

I wish to report that the earth's core is made of almost pure
nickel-iron alloy, so the supply of iron from which to make our iron
toys is assured. All we have to do is to dig a thousand miles straight
down.

we (eventually).

"new" theory there's a natural atomic reactor at the center of the
nickel-iron core.

It's an interesting theory. I haven't seen it in Science or Nature yet.
I don't doubt that it's controversial - almost everything significant in
Earth Science starts out that way. It will probably take at least ten
years to confirm or refute,

No, it's rusting in the form of steel cars, metal structures, bridges, etc.

It's burning in the form of sodium-vapor streetlamps, solid rocket fuel,
refinery operations, etc.

One of the primary laws of physics is that matter cannot be created or
destroyed... so the metals aren't going anywhere, only being converted into
stuff which is unusable.

I believe this theory. How else could the core stay so hot after millions of
years without an internal reaction?

But we are not massive enought to rate a micro-dot black hole at the
center of the atomic core. pity.

This ultimate recycling machine has been proposed in physics research
and may have been mentioned in sci.physics.research. It's a Large Mass
Spectrometer, binning vaporized osmium, boron, carbon, copper, and all
other elements into bins as the charged atoms (ions) fly past The Big
Ass Magnet. Some designs operate out in space.

By the decay of radioactive elements in the core. All current theories
are one form or another of this; no chain-reaction fission is involved.
It turns out that one doesn't need much radioactive decay to account for
the net power flow. This will be the big problem for the
core-is-a-reactor theories, to prove (without peeking) that the power
comes from fission versus decay.

Go to the store and buy a pumpkin- paint it in the form of the earth- blue
for oceans, green for continents. Find a needle and pry out a piece- that's
the amount of natural resources used in all of human history- now wipe the
piece in the blue part- thats all the pollution .

Interesting. Can I ask where those facts are from? Not that I fear we're
running out of metal any time soon, (the media is saying we're all gonna die
from bird flu...) but it's good to know the facts. Look at Mars for instance...
that would have made an epic planet to mine iron from, except it all rusted!

Well, I know for sure the iron is still there, it just has to be
extracted a little differently!

Right. I think iron is the second most abundant element on earth.

I used to work for a crack metallurgist. He said except for a few
metals, there was an abundence in the earth's crust, but in lower grade
ores that would be less economical and take more processing, but as we
need them we'll do it.

Taconite is a good example. Here in the Iron Country of Northern
Minnesota they used to mine very high grade hematite. When it began to
peter out, they developed ways to process the low grade ore taconite. In
developing taconite they developed pelletization, which is boon to
industry. Pellets can be shipped in cold weather, stockpiled, and have
limestone and other minerals added in during pelletization so that it
doesn't have to be done at furnace.

There is still lots of native copper (elemental copper, not oxide or
other ore) in Michigan, in very deep mines. But processing is so cheap
these days that much lower grade ore in shallower mines dominates copper
supply, and Michigan's deep mines are dormant.
