What are you? (another certified village idiot like myself?)
With that sort of LL-1 naysayism and obviously without so much as a
freaking clue as to what the LSE-CM/ISS is all about, can you possibly
get yourself any more negative, so that we can make good usage out of
the intellectual naysay implosion of such negative energy before your
turn yourself and your antimatter worth of naysay-intelligence into a
black hole.

Though using the moon itself makes perfect sense. However, how exactly
do you plan upon safely and efficiently getting whatever's of robotics
and crew to/from that dark and reactively nasty surface, or rather for
getting such deeply underground unless it's initially placed upon a
nearly coal like basalt terrain that's of carbon/soot, iron and
titanium coated plus salty surface that's merely illuminated via
earthshine.

Gosh folks, come to think of it, I've never once considered a tethered
asteroid, nor would I. As how absolutely dumb and dumber of an idea is
that, or what?

I promote instead an Earth to Space Mass Driver.
Once your stuff of a few kg per package gets into LEO, then what?
Are you talking about sending ISS those little pods containing their
happy-meals and extra toilet paper via Mass Driver?

The notion of Earth's magnetic field dissipating is rather frightening.
Get yourself used to it because, we've already been paying the price by
way of taking on greater and greater hard-X-rays and other nasty forms
of dosage as is, and therefore we should get with the program of making
our next generations of DNA into a more rad-hard DNA, as in
intelligently redesigned so as to tolerate a 100 fold increase in the
influx of such radiation, plus at least another 10 fold increase in the
local/artificially created forms of radiation that so happens to
include a great deal of discarded Radium that'll quite nicely sustain a
1600 year half-life of providing us with the nifty likes of Radon, that
which rather quickly becomes good old lead, of which knowingly
contaminates everything in sight. So, we'd best improve our DNA to
also tolerated more lead in our diets and our surrounding environment
because, like CO2 without a sufficient population of diatoms, the likes
of extra lead and CO2 are soon going to be within and around just about
everywhere.

Christ almighty on yet another stick, we have collage graduates with
their doctorate degrees of dumbology that can't even safely deal with
fire, with over a million homes or apartments damaged and/or destroyed
because of their having candles in use that are obviously a whole lot
smarter than the supposedly educated humans that were supposedly
encharge. What the freaking dumbology are we even doing with using
candles anyway? Is this still the 18th century? Or are we supposed to
be living in caves?

You do realize that a millionth of the surface area of mother Earth
(5.112e8 m2) is entirely within the grasp of existing technology, as to
deliver on behalf of end-users with safe, clean and renewable 2 kw per
soul. Or, is that still asking too much?

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 Earth's average inclination to its orbital plane is said to be...
23.5 degrees. That's not a constant, I think the Earth in its movement
around the Sun is perhaps a bit more dynamic than people generally
realize with the model of the solar system with the wires and styrofoam
and so on and so forth.

Then there's the Moon, with it's distance to the Earth varying by
several hundred thousand kilometers over the course of some years, and
that's somewhat eccentric in its ellipticity when its distance from
center to center is only about twice that.

Then, a somewhat large asteroid is possibly within Earth's path in
perhaps 2038 or so.

Human-caused industrial age climate change is real and obvious.

"Chicken Little" is a fictional barnyard animal in a story where
Chicken Little receives perhaps a drop of rain on his head. He
proceeds to proclaim "the sky is falling" and thus ensues riotous
uproar on the farm. I forget how it ends.

Change begins at home. The sky will _always_ be falling. While the
moral there is basically to proceed as if unknowns will not happen, yet
to be prepared, there are many things about the environment that are
quite well known in terms of the scientific method and true, undeniable
facts and so on.

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.

Nah, that's again just kind of fire-in-the-theater-shouting, but is not
far from the mark, that's basically a true statement.


I'm a space enthusiast. To get to space en masse we, Earthlings,
Terrans, Homo sapiens sapiens, need (safe) cheap (reliable) access to
space.

The Earth to Space Mass Driver in 100 tonne pods. Cheep.

About energy, uh, there is a lot of recycling to be done. There was an
electric automobile before an internal combustion, although there was
probably a steam powered one before that. In one of Piers Anthony's
stories he has a car race with basically no rules and the winner is a
nuclear powered automobile, that hits Mach 1 on the ground.

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.

About energy, they call cold fusion these days "chemically assisted" or
"low energy" nuclear reactions. Sustainable sun-style fusion probably
takes place on mass scales of say, the Sun, not on Earth, with the iron
(Fe) being the nuclear equilibrium element, but 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 universe is infinite, infinite sets are equivalent. Points are
polydimensional, in real analysis, about the real numbers of the number
system. If you're going to talk about infinity, it's probably good to
start with potential vs. actual. C'est non sequitur.
