Re: Lunar Space Elevator simply isn't for everyone

Ross A. Finlayson;
What's the deal with the Earth's magnetic field shifting around in such
a dramatic manner? That doesn't happen every five-six hundred years or
Earth life would already have rad-tolerant DNA/RNA/ life mechanisms, or
would have been quie ruined every several hundred years. The system
appears to be remarkably robust and consistent, and dynamic.
The mostly iron core of Earth via friction and geothermal cooling is
quite naturally winding itself down. So, unless it manages to flip
into reversing itself, as apparently having transpired before, chances
are that Earth is simply turning itself into a somewhat bigger Mars
that'll eventually become to too TBI nasty by way of allowing greater
solar and cosmic influx to reach the surface, whereas decade by decade
allowing in a bit too much radiation as to continue enjoying life to
the fullest, especially as our atmosphere becomes gradually thinner,
thus adding further insult to injury. That is unless our "DNA/RNA/
life mechanisms" get with the intelligent design program of their
becoming more rad-hard (there's simply not enough time for conventional
evolution of most species because, we'll all be dead or becoming nearly
so long before it's too late for even intelligent design to save
whatever's remaining of life as we've known it).

BTW; I don't believe we can afford to accommodate many forms of
recycling, whereas it takes spare/surplus energy in order to recycle
squat, and more often it has been taking more of that energy in order
to recycle than to simply discard (aka land-fill, ocean-fill or simply
burning for recovering the stored energy) and simply create new stuff.
We don't have spare energy to spare, at least there's not sufficiently
clean energy in any surplus that I know of.

Using up a millionth of Earth (a footprint that's taking 5.112e8 m2)
could easily provide an average of 2 kw/soul of extra clean and 100%
renewable energy that's in addition to whatever's existing in fossil
fuel based, nuclear, hydroelectics and the lot of green/renewable
alternatives. We're obviously not into doing that and apparently our
fossil or bust mindset insures that we have no intentions of ever going
clean.

The sky _is_ falling. Humanity and life as we know it is
basically _doomed_ unless the species achieves in a very short
window of opportunity getting off the planet.
Fortunately the sky has not been falling on the somewhat newer planet
of Venus, other than within each season of nighttime it might dip by as
much as 10%, as otherwise there's already more green/renewable energy
that's easily available and offering more terajoules than we can
possibly shake a fist full of burning sticks at.

I'm a space enthusiast. To get to space en masse we, Earthlings,
Terrans, Homo sapiens sapiens, need (safe) cheap (reliable) access to
space.
In other words; is it to hell with all that's terrestrial (aka pillage
and screw mother nature for all she's worth) because you're thinking
that we're going to be saved by uncovering the wealth of whatever's out
there?

Without question the lunar element of He3 is going to become worth at
least ten fold whatever it'll take for obtaining, thus I'll have to
agree upon going after whatever's closest to home as being certainly
worth the effort.

The Earth to Space Mass Driver in 100 tonne pods. Cheep.
Another trillion hard earned bucks is not cheap. Plus costing millions
per deployed tonne isn't exactly a free ride (after all, getting stuff
to LEO is just half of the total equation), whereas it still doesn't do
us much good getting those 100t pods of whatever might withstand such
horrific G forces per transfer into LEO (though 100t pods of rocket
fuel should represent a good application), unless you're thinking on
behalf of placing the likes of our WMD/nukes in space or possibly the
task of getting rid of dead or soon to be dead bodies by the thousands.

Of your mass driver assisting in getting 100t payloads to LL-1,
accomplishing this task in the most efficient manner, is however worth
looking into.

Obviously you realize that the greater the initial G force the greater
the mass driver energy demand, thus 10 G is representing 5 fold more
applied energy than a 2 G launch, except that your mass driver expends
most of it's velocity within the first and most gravity sucking zone,
thus we should apply another 2:1 factor which makes your 10 G launch
worth 10 fold greater energy than the 2 G conventional launch that has
all of that extra inert rocket mass to deal with, that which should at
least somewhat give your mass driver the edge. Perhaps what's needed
is a hybrid mass driver as taking the place of the first stage, thus on
behalf of getting the payload and of its mostly composite
LRB(h2o2/c3h4o or LH2/LO2) 2nd stage as roughly getting beyound
100,000' while still offering 2.5+ km/s seems doable.

A mass driver that capable of getting 100t pods of stuff (aka He3) off
the moon is starting to make a whole lot of sense (36:1 better off than
Earth to LEO, although we'll obviously first have to get such
technology established on the lunar surface. I wonder how we're ever
going to accomplish that sort of task without first having established
the LSE-CM/ISS?

Have you not so much as half a brain, other than what's chuck full of
infomercial-science and those conditional laws of physics?

Don't you realize that LL-1 represents the holy grail of a mass driver
launching zone?

From LL-1, one joule of applied energy is all that it'll take in order
to launch a megatonne, as per headed towards the direction of the moon
or towards the direction of mother Earth.

By way of utilizing the interactive LL-1 zone as the gateway of what
the Earth/Moon and tidal forces of gravity energy have to share for
efficiently launching whatever, as for having represented by far the
most efficient of accommodating such opportunities is exactly why LL-1
represents itself as being a good portion of "the gold in them thar
hills". Of our initially getting tonnage to LL-1 is by far the most
efficient orbital zone we've got to work with, especially nifty if the
bulk of that tonnage had been derived from the moon to start with.

Obviously your mainstream skewed brain that has become so
intellectually bigoted and so nicely boxed in order to suit the Skull
and Bones agenda is clearly of what automatically feeds your naysay
mindset. I guess for those as happy campers being so totally snookered
and summarily dumbfounded is also of what's so gosh darn attractive, in
that there's no point in sharing the truth until long after they're all
quite dead. Whereas that way folks never have to realize how
extensively taken to the cleaners they've been for most all of their
lives. Of course being the Village chump has certain built-in rewards
as long as you remain a sufficiently brown-nosed minion of a team
player. At least that's essentially what Hitler was counting on, and
the same goes for our resident warlord(GW Bush) that has been in a
perpetual wag-thy-dog and infomercial damage-control mode ever since
9/11.

I don't think, I'm an idiot. Just like lots of people here I've been
standardly tested and found in the percent on the good side. I just
say that. On the idiot scale, even Feldmann's an idiot. That seems
rather small-minded in terms of these broader concerns.
No idiot thinks that he or she's a true idiot (myself included).
That's the ongoing problem (aka GW Bush), as it seems we're being
continually judged and thereby controlled by these other idiots that
can't possibly realize what absolute total idiots of moronism they are
to begin with.

ITER is probably going to release a lot of energy, just not sustainably
in terms of reactor uptimes of the lifespan of the Sun, and yes the Sun
is a great source of energy.
The sun is 99.9% of what's makes Earth tick. That is up until we're
cruising (aka elliptical orbiting) our way past Sirius at less than
..086 ly every 100 and some odd thousands of years.

If you're going to talk about infinity, it's probably good to start with
potential vs. actual. C'est non sequitur.
Exactly my point about establishing the LSE-CM/ISS for the greater good
and potential of achieving those better actual numbers than otherwise
obtainable. Or is that concept still too complicated to understand?

BTW No.2; what obviously pisses off the mainstream status quo more
than anything are the unselfish endeavors of independently honest
individuals that actually give a tinkers damn about improving the
quality of life for the lower 99.9% worth of humanity, as well as that
of salvaging our badly polluted and thus spendy environment, that's of
lately getting to be the global warming demise of most anyone that's on
our axis of evil list, which apparently includes ourselves if getting
storm-surge and/or weather traumatised simply because we're too
uneducated and thus too dumbfounded and/or of being just too damn poor
to matter. Apparently the very last boat-rocking thing you'll need to
do is to focus our limited resources and talents upon what has been
doable, especially as for whatever's a whole lot more affordable than
for our not having done something about.

The added proof that I've become more than sufficiently right is that
these well established Usenet lords and wizards claiming as being so
all-knowing are merely the e-MIB as the official Usenet naysay
rusemasters working their wag-thy-dog of infomercial-science, as to
accomplishing as much disinformation and/or of enforcing evidence
exclusion on behalf of achieving as great of brown-nosing as possible
instead of their contributing to the topic at hand is their usual
status quo. It's also what they do best.
