I tend to agree with your assessment about that individual. However,
even though some ill informed folks are fascinated with Venus for the
inconceivably wrong reasons, that shouldn't put us off thinking
creatively about Venus. After all, its still an interesting planet.

While the surface is waay too hot at present and the atmosphere is
poisonous to life at present, it should be remembered that at an
altitude of 50 km or so, the atmospheric pressure is the same as that
on Earth, and the air temperature is a balmy 70 F - and the CO2
atmosphere is 3 times as dense as that of Earth's nitrogen oxygen
atmosphere.

This inspired the famous astronomer Carl Sagan to speculate that
humans might develop engineered free floating plants that process the
CO2 in the Venusian atmosphere into carbon compounds

In 1967 Buckminster Fuller suggested that geodesic domes 1 mile in
diameter could float in Earth's atmosphere being homes to 50,000
people. It is quite possible with 2.5 kg per cubic meter lifting
capacity, that such floating cities might make an appearance in Venus'
upper atmosphere. Such stations might tend aerial gardens that are
engineered to transform the Venusian landscape into something more
earthlike.

I have proposed elsewhere that ICF based nuclear propulsion system
could be used to harvest rich asteroids and bring them into orbit
around Earth. There, teleoperated factories on orbit could process
asteroids into useful products that would then rain down to users on
Earth.

A similar setup can be imagined for Venus. A ring of asteroidal
factories and space colonies could send down engineered plants and
free flying cities. We could call them 'cloud minders'

The atmospheres of Saturn, Uranus, and Neptune have similarly friendly
environments where cloud cities might be built - if a reason could be
found to build them.

http://en.wikipedia.org/wiki/Colonization_of_Venus

Atmosphere of Earth has a density of 1.26 kg per cubic meter. The
atmosphere of Venus, at an altitude of 55 km above the surface, is
mostly CO2 at Earth normal pressure and temperature, and its density
is around 3.75 kg per cubic meter. So, a plant that was genetically
engineered to form bubbles of oxygen inside them, would have a
bouyancy of about 2.49 kg per cubic meter. That is, if a plant formed
a ball say 1 meter in diameter and absorbed CO2 and sunlight on its
outer surface, and exhaled oxygen and water to its interior, it could
mass 1.3 kg spread across 3.1 sq meters of tissue area. That's 413
grams of tissue per cubic meter. With a density of 0.6 grams per ml,
that/s 690 ml per square meter. 0.69 mm tissue thickness.

To close the cycle, approximately 1/5th the mass should be animal
tissue. So, the plant tissue would be reduced to 0.85 mm and tiny
creatures ranging from mites to mice could be bred to inhabit the
interior and nibble only so far into the tissue layer, perhaps running
like rates in a exercise wheel, to bring fresh material to the bottom
of the sphere to eat it, and circulating the water and waste products
through the 'lawn' of the interior.

The plant - has a capacity to process sulfuric acid into sulfates
which are dropped from the balloon. Reproduction would an interesting
process - with perhaps tiny balloons fissioning off like dandelion
seeds. This favors mites rather than mice - which can ride on the
tiny balloons when the spawn. Mice sized infections of the interior
of offspring would require larger sized fissioning balloons.

The whole life process takes sulfur out of the air and turns it into a
solid - the same way certain life forms take calcium out of the ocean
and make solids out of it. The life forms also take carbon dioxide
out of the atmosphere and turn it into solids - plant material, and
animal tissue, and waste products which is mixed with sulfur and
dropped out of the system as more is added. Free oxygen also leaks
out of the system - so over time the atmosphere changes to Oxygen and
Water vapor -

While this is going on Fuller style cloud nine floating cities would
be possible. A 1 km diameter sphere carrying an oxygen argon
atmosphere would be 1 billion times as massive as a 1 m diameter
sphere so 1.3 million tons of material spread over 3.14 sq km of area
would allow 413 kg per sq meter. A sheet of glass 16.3 cm thick would
be possible with this system. A sheet of PET film (impervious to
sulfuric acid) could be 25 cm thick (10 inches!)

Clearly a multi-layer system of aluminum reinforced triangles imbedded
in PET film with a glassy interior layer would easily be made to
withstand the rigors of Venus, especially if deployed near the poles.
Since oxygen is lighter than carbon dioxide, a set of doosr at the
bottom of the sphere, form an airlock to admit aircraft and space
craft - just as a door in an underwater habitat remain open once the
pressures are equalized.

VTOL style propulsive skin aircraft/spacecraft similar to those used
on Earth, powered by lasers from space - which also power the spheres
- from an orbiting industrial ring - would easily navigate to these
cities and back. The cities themselves are made from asteroidal
feedstock on orbit and deorbited collapsed and then opened after
they've slowed to subsonic speeds. At 50 tons per person, each
sphere carries up to 65,000 people and nominally carries 50,000 people


The city, like the plant systems, drop sulfur and carbon solids from
them, while releasing oxygen and water vapor into the atmosphere.

Molecular sieves and pumps maintain oxygen atmosphere. A simple
system of electrolysis driven by laser is used to take sulfuric acide
and reduce it to hydrogen and oxygen and sulfur dioxide. Another
laser driven system involves iron catalysts and carbon to break oxygen
from CO2 using laser power from space.

H2SO4 --- SO2 + H2O + 1/2O2
CO2 --- C + O2

Carbon and sulfur can be combined into a wide range of compounds that
when dropped to the lower atmosphere would cycle up more CO2 and more
H2SO4 to convert into water and oxygen.

http://en.wikipedia.org/wiki/Organosulfur_compounds

Some of this could be engineered into the mice and plants mentioned
earlier.

Given the mass of the Venusian atmosphere, the mass of materials
needed to be processed, the efficiency of the processes used, and the
energy available to process them - we can estimate the time frame for
full conversion of the Venusian atmosphere to water and oxygen.

Given the amount of argon in the atmosphere, I wonder what happened to
the nitrogen? It likely reacted with the rocks below and released
the sulfur that we see. If the temperature drops - and chemistry
changes - enforcing a planetary cooling on Venus by lowering CO2
levels - we may find that when the surface conditions start to change,
nitrogen levels rise, and sulfur gets sucked up leaving carbon and
water on the surface. At that point the plants and animals and cities
have descended to the surface and operate freely there.

Not that your plan of action as based upon working from the cozy and
buoyant 50 km altitude on down isn't technically doable, because it
most certainly is.

However, since equalized pressure is not a negative/insurmountable
biological issue, and If technologically situated upon that
geothermally forced surface as is (though obviously not in the buff),
and were given unlimited local energy (fully renewable none the less),
what couldn't be resolved on behalf of human habitats?

Some have said that the surface of Venus today is safe for human
habitation. These same individuals say the moon is not. We don't
have to guess about the surface condition of either.

Here's a picture from the surface of Venus

http://antwrp.gsfc.nasa.gov/apod/ima...nera13_big.gif

that was sent by the Soviet Venera 13 space probe sitting on the
surface of Venus after parachuting there on 1 March 1982. The
vehicle, even though safeguarded from conditions in its own safe-like
enclosure survived only half an hour in the blazing 482 C (900 F)
temperature - about twice as hot as your oven at home. The air
pressure was 92 bar - 92 times sea level pressure on Earth. Chemical
analysis of the droplets in the clouds surrounding the lander indicate
they wree pure sulfuric acid.

Now if any of you have ever left a chicken or a steak under a broiler
at 500 F for too long, or if any of you have ever cooked a whole
turkey in minutes in a pressure cooker (which operates at 2 bar) - or
if any of you have ever dropped anything organic in sulfuric acid -
you may have some inkling of just how BAD a day you would have if you
found yourself on the surface of Venus!

Twice as hot as the broiler gets, 40x more pressure than a pressure
cooker, and clouds of liquid sulfuric acid.. hmm..

Any organic material, would burst into a weird sort of flame, and
dissolve away in seconds leaving the bones behind which might last
nearly 20 minutes or so before dissolving altogether.

This is NOT conducive to life.

As far as the moon is concerned.

We've been there.. Here's a series of films shot from Apollo 15's
Falcon lander.

Euugene Cernan said once that naysayers can spin all sorts of crazy
theories they want about Apollo,to take away the thrill, and the glory
of those missions to the American people, but there's one thing
they'll never do, and that's take those footprints I made on Montes
Taurus the Winter of 1972 away from me!.

Now it is true that there is more radiation on the moon than on Earth,
but the amounts are tolerable if stay times are short - less than 90
days. For those who wish to stay longer than a year on the moon, you
need to get underground or do something different. This is an issue
for long-term habitation. Not for short term exploration or tourism
or even industry if you rotate work crews or work tele-robotically
from shielded bunkers

It is an issue that will be resolved in my estimation.

But Wernher von Braun was a such a smart fellow as mostly Jewish

have continually worshiped "the *******" in charge of having put the

Wonder why there's still nothing of objective evidence in full support
of such an accomplishment, that which oddly can not be independently
replicated as of using half the inert GLOW or much less that of any
sort of fly-by-rocket lander.

Why is the new and greatly improved JAXA/Selene science so unusually

In other kind and constructive words, there's actually hundreds of

within that relatively cold nighttime clouded season (say at 60+ km).

Sadly, this above statement of yours is simply another good example as

Your bipolar form of using conditional physics and genetic infused
naysayism is showing its ugly Semitic head once again.

Using your subjective and otherwise conditional laws of conditional
physics in order to discredit what can be otherwise technically
accomplished with such a surplus of local energy and resources to
spare, is only boasting as to further proof-positive and otherwise
nailing down about your BD(bipolar disorder), that's forever going to
continually object to anything on behalf of Venus.

The same laws of physics that makes all things of Mook function
without a hitch and at good profit margin to boot, instead could be
utilized on behalf of making nifty stuff happen on behalf of Venus,
regardless of how hot and nasty that raw environment is to naked life
as we know it.

Your "This is NOT conducive to life" should have been more properly
stated as 'not conducive to naked dumbfounded life'.

Pressure once equalized is a biological no-brainer, and of such dry
temperature isn't hardly an issue with unlimited local energy and
insulation as good as R-1024/m is certainly not hardly a bad thing,
any more so than CO2--co/o2 is the least bit insurmountable. Even
crystal dry S8 is 100% harmless.

Unlike our naked and thus unavoidably anticathode reactive moon,
whereas one bad halo CME or series of cosmic gamma events (of which
there are always many), and within minutes human DNA is sufficiently
done for (aka 'past the point of no return'), whereas on Venus our DNA
is extremely well protected, far better off than here on Earth, as
well as there being no gamma radiating moon adding its lethal energy
trauma plus gravity/tidal force of global warming affect to the
already geothermally forced situation as a toasty surface environment.

Of course, those easily fooled by way of purely subjective evidence,
by mainstream hyped eye-candy of all things inert, especially when any
number of objective forms of evidence has been continually discounted
as though Old Testament taboo/nondisclosure rated, leaves little to
conclude other than brown-nosed birds of a Semitic feather (like
yourself) do in fact flock together.

Your clearly bipolar skewed way of taking each and everything out of
context and then intentionally interpreting on only the utmost
negative aspects, including your persistent exclusion of whatever
intelligent use of technology could muster, is just further proof-
positive of your bipolar intentions of continually doing everything
you possibly can in order to undermine or disqualify each and every
consideration on behalf of polishing anything except Mook stuff.

Yourself, GW Bush and company of brown-nosed minions are clearly one
in the same as Hitler, except combined and while off your bipolar meds
is when you folks are much worse than, as well as having polluted and
exterminated far greater numbers along with your mutually faith-based
perpetrated cold-war(s).

Your intentions are as always every bit as clear as another DARPA S-
Band Chapel Bell transponder.

True enough, as it's mountainous terrain is looking almost as though
it once had its very own massive moon, and of its crystal dry and thus
safe lower atmosphere is perhaps much like Earth prior to getting iced
down by way of an icy proto-moon and from other icy contributions.


While the surface is waay too hot at present and the atmosphere is
poisonous to life at present, it should be remembered that at an
altitude of 50 km or so, the atmospheric pressure is the same as that
on Earth, and the air temperature is a balmy 70 F - and the CO2
atmosphere is 3 times as dense as that of Earth's nitrogen oxygen
atmosphere.

Life even as we know it can adapt to pressure, even to considerably
less O2 and lots of CO2, not to mention dry S8 isn't even all that
insurmountable unless you haven't the time to adjust/evolve or the
technology in order to artificially create whatever local habitat
environment you'd like.


This inspired the famous astronomer Carl Sagan to speculate that
humans might develop engineered free floating plants that process the

Venusian floating cities is pretty much exactly what my rigid
composite airship represents, whereas robotic airships or as those
configured as fully human sustaining airships is technically doable
within existing technology. Too bad folks that so often claim being
so all-knowing actually do not let on about knowing squat about
accomplishing any R&D on behalf of accomplishing such rigid composite
airships.


I have proposed elsewhere that ICF based nuclear propulsion system

POOF City at Venus L2 is cool and downright nifty, whereas any amount
of volume and mass isn't the least bit of a problem to interactively
sustain that kind of halo orbit, offering our best depot/gateway for
all sorts of future to/from Venus expeditions.


The atmospheres of Saturn, Uranus, and Neptune have similarly friendly
environments where cloud cities might be built - if a reason could be
found to build them.

How about the good old and well enough peer replicated reason being,
there's clearly signs of other intelligent life existing/coexisting on
Venus?
