Subject: A modest proposal
Newsgroups: sci.space
I expect to get flamed for this, but it's been more than 20 years, and my
understanding is that any research concerning moon rocks has already been
done. Considering how much moon material there is down here, why couldn't a
few of those rocks be ground into little bits, mounted and sold to the
people who financed those rides in the first place - i.e., the American
public. Why shouldn't we all have a shot at owning a piece of the moon?
It might even bring down the deficit a bit.

1. Transport costs to the sun would be c. $50,000/kg.
2. About 5% of launches go *boom*, to quote a previous post.
Radioactive materials must be packaged to survive
this, which can and has been done but is expensive for
large amounts of material.

If you can convince congress that the cost of getting many hundreds of tons
of waste out of the Earth's gravitational potential and flying nuclear waste
over the heads of the constituents is worthwhile, you're all set.
You may be correct that it would be cheper to launch it all away than to
constantly pay big dollars on shuffling around and researching 'safer' ways
to store the stuff. But maybe that is a good thing in that it keeps money
being spent in the US and keeps jobs!

No, B-G algae did more...BUT they did it w/o awareness that they were doing

\And that is exactly the problem,as illustrated so well on this board.
/When the issue of world population emerges noone can agree.
\If the first world subtly or otherwise advocates population control
/they are accused of being both selfish and racist.
\Unfortunately population growth in absolute terms is far more distructive
/when it means more roads,fossil fuel consumption,conversion of agricultural
\acres to paved urban jungles.
Absolute bullshit. The Jungles aren't being burned down by industrialized
people, or replaced by cities. They're simply being turned into desert.
Greater population means more fossil fuel consumption only because
competing sources of energy which are very clean (specifically,
nuclear) have been legislated out of existance, after being legislated
into the least clean form it can take (i.e. the "environmentally correct"
Carter administration banning the recycling of nuclear fuel increaced
the amount of "waste" material a thousandfold and the amount of wasted
effort probably more (since most of the fuel is still useful).
The Sahara wasn't made by cities, or by people burning fossil fuels.
It was made by goats.
\It means all these things much more in the developed countries than
/the third world,but these arguments are frequently used as "smoke
\screens" and leave all population control discussion at loggerheads.
The developed countries can afford to save their wilderness. The
undeveloped ones can't. The developing countries may or may not get
the chance to try, depending on how fast they develop. An interesting
place to look at this is Vietnam: can they get industry fast enough
to not have to destroy their rain forests in order to eat?
\Population control in terms of environmental damage is far the more
/crtical in the USA than Southeast Asia or non-industral areas.
Fine. Supposing I get my tubes tied tomorrow, how in hell is this going
to stop the destruction of the Amazon? How is my not having one child
going to be more helpful than some stupid Brahmins not having
ten (usually all boys, because that's what they've done with _their_
birth-control resources: aborted all of the girls...
How is my sacrifice of the one or two kids I might have going to help
the people in the third-world who are right now having many more kids,
who they cannot take care of without destroying large parts of their
enviornment?
\The world collectively must first admit that human numbers need to be
/controlled. If we can't do this nature eventually will in the cruelest
\terms.
/Unfortunately relgion is 2000 years out of step with reality in most
\places and the status of women the poorest in areas with highest
/population growths.
How you can talk about collective guilt and the need to improve the
status of women at the same time bothers me. Because if there is
such a thing as collective guilt, _they're_ having all the babies.
Personally, I think the only thing 2000 years out of step with reality
is the collectivism. Because that gives all the people an out from
their individual responsibility, and in the avalanche of enviornmental
destruction, each snowflake can plead innocent (apologies to Stanislaw
Lem).
\Perhaps what will evetually happen already has happened in Croasia.
/Open season on all two legged bipeds.
\Perhaps not a bad idea,but not the most humane method of population
/control.
No. That is a case where humans, and the surrounding enviornment (as
trees take the place of fossil fuels in places the fossil fuels
can't get to, and whole forests are wrecked for fuel), are both
being destroyed by a bunch of fascist communist, _collectivist_
("We're going to take those Muslims to task for the collective sins
of their religion, and kill all the five-year-olds!") assholes.
You look like you're on the road to becoming one, you're already

I'm not going to flame you. I have a better idea, though.
NASA currently treats the moon rocks as if they're irreplacable,
and there isn't a huge moon still there. They have acted all along
like there will be no more flights to the moon...
Why not rebut that belief: one could build an unmanned sample return
mission that tested fuelmaking from native resources in order
to take back as much moon rock as could be auctioned off...
Any investors?

There have been measurements made from just about every type craft you can
imagine; airplanes, sounding rockets, setellites, etc. Papers detailing
those experiments can be found routinely in Science and JGR issues as well
as occasionally Physics today and Sci Am. You can call the National Center
for Atmospheric Research (NCAR) here in Boulder and request that you be
sent info on CEDAR (Coupling Energy and Dynamics of Atmospheric Regions).
From their newsletter, and their conferences, you will be directed to many
more works on the subject.
>[2] If measurements are done, what are they measuring ? and is this

Measurents have been made in UV transmission (amount of UV hitting the
surface) UV reflectance (from satellites) and in situ. In situ measurements
have also measured [CFC] and chlorine radical abundances.

It is not uninformed or naive to state that I consider certain

priniciple of absolute property rights and never has. It works on the
principle of who has the most guns and the least morals. That doesn't

One can assume that at the time Europeans arrived that the native
peoples "owned" their land through whatever mechanism was
appropriate. The ownership might be vested in the tribe. Property
rights in parts of the US went from tribes to settlers sometimes by
purchase and contract. In those cases there was a valid transfer of
property rights from one group to another. Ie, mutual contract. Sad
to say it was not all so up and up.

I've not heard Belfast described that way before :-) If saying that
going onto someone elses land without their consent and without
recompense is arrogance, then I'm the most arrogant SOB you are ever
going to meet. If I accept this logic it means that the Serbians are
justified in forcing Croats and Moslems of their lands at gunpoint in
Bosnia. Or do property rights only hold if you are white and
christian?

I hardly said it was simple. I said it was a matter for independant

I've never even seen a documentary on the subject. I have, however,
had contact with an Australian aborigine, and I have certain strong
principles concerning the use of coercion as a means of public
policy. I discuss the property rights issue because I want to see
strong property rights in space, rights invested in the original
settler that can be transferred by that settler and ONLY by that
settle in any way they deem suitable. The abuse of aboriginal peoples
has a great deal to say about how statists deal with ownership. It is
just a matter of convenience to be abrogated whenever it ceases to be
convenient.
I'd much rather we had a new philosophy with us in space. If a
soldier comes into your house and says the state has declared it owns
your property, you kill him; and then you get off at the trial
because it is declared that you defended yourself against armed
robbery. (Guess what happened to native peoples who defended their
property? They got hung, drawn, quartered and declared traitors to
governments they owed no allegiance to. Exactly which side WAS the
civilized one?)
I think space settlers will eventually have to be very well armed as
individuals because the idea of state derived property rights is
indeed too pervasive on earth to ever be changed.
PS: Notice how I've cleverly brought this discussion back to space?

First, no organic life form *can* survive lower down. Evolution can't
achieve what's biologically impossible (cf. Antarctica is lifeless,
except for a few lichens and some penguins and seals on the coast. The
life forms on Antarctica had millions of years to adapt as the continent
drifted over the south pole, but they died instead.)
Second, algae are the only thing there would be any point in trying to
seed Venus's atmosphere with, because whatever you use has got to be
able to make its own food.
Third, and most important, no life form even similar to anything we have
on Earth at the moment could survive in Venus's atmosphere, not so much
because of extreme conditions of temperature etc., but because the
required nutrients (particularly water) are not available. There is
hardly an atom of hydrogen on Venus, except for in the sulphuric acid.
Also, where would an alga drifting in the upper atmosphere get the
traces of minerals it would need?

A possible means of handling these items is to place certain
properties in the hands of institutes at the time at which they are
removed from government ownership.
So Yosemite might go to the Sierra Club and the water hole might go
to world radio astronomy consortium.
Thereafter all reallocation of frequencies would be by sale of the
owner (who has absolute property rights :-)
And if you want to explore another area of the spectrum, you need
only purchase the frequency from the current owner(s), rather than go
through a long political battle.

Privatization means the current assignments become tradeable
property rights. Thus, if Barry needed a used spectrum for
a new radio astronomy experiment, he would go to its owners
instead of the FCC bureacracy to negotiate purchase or rent of
time. And vice versa, the FCC couldn't pull somebody's frequencies
without compensation. Violation of the property would be trespassing
and treated as violations of assignment are now. International
treaties wouldn't be effected except to the extent Libertarians can
renegogiate them to follow the tradeable property rights model.

Worse actually, the money *evaporated* as the speculative real estate
bubbles broke. $5 million dollar buildings were suddenly worth only
$2 million. The money evaporated. Most of the money supply is not in
dollars, or coins, or gold. Most of the money is "on the books" of
investors. When those book values change with changing markets, the
amount of money changes. With reduced *collateral* value, banks, S&Ls,
and corporations have less assets that can be changed to liquid money.
That's the real cause of the S&L crisis, less than 1% of depositors
money was siphoned off by fraud and misuse. Most of it just disappeared
as the value of the real estate it was loaned for declined.
