It is a free lunch - government subsidies and public investment. Best
efforts, then either bankruptcy or impressed Enviro-taxes to fuel the
fraud. Be at the top of pyramide enjoying the view, not near the

Geothermal power systems can only work as heat engines. That means
they transport heat from down below (where it's hot) to up here (where
it's cooler) through some machinery that can convert some of the heat
to usable energy on the way by.

But, it will unavoidably dump not only the converted heat that is
the "power supply" (just like in a generating station that burns
hydrocarbons) but also the unusable waste heat...

wait for it...

into the Environment!

Hence it will contribute to Global... er, ...Climate Change.

Eventually, somebody will explain this to the Greenies (using many
many very small words) and they'll crap their drawers.

They can't comprehend any explanation that has more than three words
in it. You have to figure out a 3-word spin byte or slogan that
describes it all. Oh, and it has to rhyme so they can waste
all kinds of energy to get to earth spots and chant.

Good luck because you'll need a politician to help.

You can never convince a person whose motivation isn't
truth, but misuses information in order to advance
their personal agenda.

There's a one word cure for thoughts that humans are
exclusively responsible for climate change, and that
word is "Chaos."

In short, we can never know.

Honey, everybody has a personal agenda. The key to

your people's personal agendas in the same direction
which is, hopefully, getting the work done.

Since you capitalized Chaos, are you trying to obfusicate

Chaos theory is a math technique to create patterns.

I'm a little shocked that you've apparently taken to gunning
for people when usenet is about an exchange of ideas. That
being said, I'll give you the keystone concept anyway. Chaos
is the study of complex nonlinear dynamic systems. The theory
originated during an attempt to more accurately predict weather
in the longer term. If you want to think it is about patterns,
you're on your own, and knock yourself out.

Umm, no, what apparently happens is the water pumped down to get heated also
lubes the faults, things start slipping, and you get earthquakes.

This has been known for decades but no one wants to acknowledge it since
geothermal energy is "green" and therefor couldn't possibly have undesired
side effects.

Seems like a reasonable question to me, in the context of *personal*
agendas. Or are you thinking of so-called universal truths?

Um, it *is* about finding patterns in what seems at first blush to
be patternless. If it were not, it would be *useless* for predicting
weather.

As others have mentioned, there are issues. But the big one is,
it will never produce any significant fraction of our energy needs.

The heat flux from inside the Earth is round about 75 kW/km^2.
That's an average, and it's not all that precise. Depending on who
does the measuring it can be higher or lower.

It's not evenly distributed, but concentrates at places where there
are things such as volcanoes, subduction zones, and so on.

In such places, it is possible to get some local good out of
geothermal.If you live near a volcano, or a hot spring, or a
geyzer, or some other volcanic type activity, you may be
able to get your house heated using it. Iceland does quite
well doing this. So does New Zealand. So do a few other spots.

But on a global level, it's not going to do much. Most places
get only 10 or 20 kW per square km. Or less. And you only
get a fraction of that as useful energy (electricity or whatever)
so you get maybe 5 kW per square km.

So, to replace a 1000 MW electrical power station, you would
need 100s of thousands of square km of collector. It seems
quite unlikely.

The difference between .506 and .506127 is huge where it
comes to chaotic systems. Just ask Lorenz. You can't measure
weather conditions to that level of accuracy on an ongoing
basis. We're lucky to measure weather to three significant
numbers. Lorenz said so, and our state of the art hasn't
progressed significantly since his day. Check the predictions
for your region against the subsequent reality over the longer
term and report back in about a year. Where I live they're
maybe about 40% correct.

Chaos isn't about patterns. It is is the study of complex

functions can create patterns doesn't mean we consider
the trig functions to about patterns. We have other uses

What do you think Lorenz attractors *are*? They are diagrams of the
future states a system can evolve into.

Nonsense. It's useless for predicting long-term changes (climate),
but it's becoming more and more useful for shorter periods (weather).

It makes much longer-range predictions than the previous linear
models.

What it's completely useless for is retrodicting proof to support
the claim that human activities are a significant factor in long-term
climate change.

I have no idea what your "understanding" of chaos theory may be, but

That is quite correct, but does not support your contention that
it's "useless" for predicting weather.

The existence of attractors in chaos theory are what makes it useful
for making predictions. A complex system like the Earth's atmosphere
can exist in many states, but not infinitely many. Which states it can
transition to from a given state are _limited_ by chaos theory. Trying
to predict the future behavior of the entire atmosphere is futile.
Small pieces of it are somewhat easier.

Forty years ago in Southern California the temperature couldn't be
predicted for three days out to within five degrees, and the
probability of precipitation was a complete crapshoot.

Currently the reliable range is about a week.

Is it perfect? No. Is it useful? Yes.

Chaos theory is exactly about patterns. I ask you again; what do you
think Lorenz attractors *are*?

You certainly are, if that's what you know of chaos theory.

been looking after her own interests.

Of course it is. The only portions of weather we can predict
with some degree of accuracy appear to be more or less linear.
That's the short term weather of one week or less.

Filling up space by going off track with "discussion"? Where
weather is concerned, Chaos theory attaches to real numbers
and their fallibility based on the natural limits resulting
from our inability to measure the actual initial conditions
with accuracy sufficient to long term accuracy. That infinite
variations are not possible is more the case, in studies we
undertake, than not. Just what is it you're bringing to the
discussion here?

> Which states it can
> transition to from a given state are _limited_ by chaos theory.

Transitions are not limited by theory, but by nature. Unfortunately I
find myself feeding into your side discussion. Like so many others
you lose sight of the discussion in making the theory drive nature
when theory is merely an attempt to describe natural events.

> Trying

You fail to understand Chaos theory at all. The entire purpose of
the original Lorenz paper on this topic was to discuss the reasons
for the impossibility of improving weather predictions based on
having more data because we can never get to the necessary depth.

Then we discovered, as an outgrowth, that most complex systems can
be similarly described.

Gawd you're thick. Do you think that all that's gone on in the
past 40 years is growth of Chaos theory? Do you also think that
weather prediction is a science rather than a combination of
science and art? I do.

Chaos theory is one of many tools. Chaos theory itself, and the
Lorenz attractors you hold in too high an esteem, have done nothing
to actually model and predict weather. Chaos has, instead, gone off
as a sub discipline with uses in many other fields of study.

I'll will tell you again that Lorenz attractors are one tidbit of
the science, that Chaos is a study of complex nonlinear dynamic
systems. Of that study, attractors are a part, not the totality.

Those are repetitive patterns (I'm thinking in 2D now). They

Really? Are you incorporating wrong solutions into the
realm, giving all solutions equal weight? Patterns can
be used to describe narrowly focused solutions derived
from a myrid of fuzzy input data. There are multiple
solutions when the input data is fuzzy. And *that* was
the point of the original Lorenz paper, and remains the
point of Chaos theory.

Where weather is concerned, how wide are the possibilities
for a given day a month in the future? Somewhat rhetorical
but I'll answer that. So wide as to be useless, as
demonstrated by Lorenz.

Lorenz found that they were deterministic, not fuzzy, but
every little bit counts; especially,
when you consider the visicitudes of the manufacture
of floating-point processors from the spec
(IEEE-755, -855;
the first is an article in Computer magazine, 1980 issue .-)

it exposes the liberal-media-owned-by-consWervatives silliness,
where they always confuse "separation of church & state"
with the foundational dysestablishmentarianism in A#1 -- yeah,
they really, always do that, cuz TJ said the six words !-)

so, what is this remarkable Madison/Marx patrimony,

they were contemporaries, and Marx actually supported Henry Clay,
for a while, til he was subverted by The Veiled Librarian

to general relativity viz-a-vu the "curvature of space"

Nice hipshot there, asshat.

I tire of your hypocritical habit of accusing others of your own
behaviors. You accuse others of "gunning" for you while you eschew
discussion in favor of spewing vitriol.

You still have not answered the question, and obviously never will.

It's blatantly obvious from your reliance on insults and your
confrontational, accusative tone that you're not interested in any
exchange of ideas.

I am uninterested in an exchange of insults, ao our interaction is
ended.

Now, go ahead and have the last word and consider yourself the
"winner".

The difference between a rational argument (with perhaps
some emotions involved) and talking to you is extreme. The
big difference is that while BAH was at one point gunning
it is clear that she's "got it" and we're just arguing,
perhaps for the sake of it.

In your case you've not got it and you never will, probably
never can. In this discussion with you there are no winners,
just one loser, you.

BAH, it is your turn to have your say in order to close out
this little subtopic if you feel the need. Do as you wish.

In case you haven't noticed, Asia's billions are going from
pedal power to petroleum power which is why the demand
is high.

I've forgotten what I was trying to learn about. Patterns
are fascinating. I spent my lifetime trying to control
bit flows and bit patterns.

the only applications, where Chaos theory methods have been useful,
is in geology to find new pools of oil in spent wells.

You mean, let me hazard a gloss, that in a chaotic system, one that in
particular is necessarily non-linear, one can never assign a definite
effect to any particular forcing, in general, other than to say "well,
it's different than it would have been otherwise".

You might also mean that, given that the climatic system is chaotic,
it will wander around phase space ("change") without any further
intervention, so it is meaningless to say "we are changing the
climate", at least if this conjures the image that we are changing the
climate from some steady state.

We are anyway conducting a massive de facto experiment with the
climate.

But if you put energy into the system, you increase the potential for
excursions of the sub-systems. There *is* a steady state; climate *is*
the sub-systems and their variability. "State" is not necessarily
static.
