I really did study physical chemistry. Primary author on 2 papers in Journal of Chemical Physics, also.:)
But there are two problems, I earned my six-year degree 4 years ago and haven't looked at anything chemistry since (nice cushy six-figure IT job), and even while in school, my studies were so far detached from water chemistry and such that I would have never known exact numbers, pressures, boiling points, etc, related to this article.
being a walking information book never makes a great chemist, *understanding* concepts does (try taking a graduate quantum chem exam with an open book to prove this theory);)
has my physical chemistry degree failed me?

Carbonate The Ocean
·
· Score: 1
I completely agree that the ocean in general is more than capable of absorbing enough CO2 to make a difference, and that this dissolution of CO2 is completely natural. I thought I had made that point more clearly in my previous post.
But as far as solubility goes, while I will agree that pressure plays a part in the solubility of CO2 in water, temperature is much more important in the natural cycle, since at the air-water interface the pressure is 1 atmosphere.
You are right by saying that pressure will play a much larger part in this artificial injection experiment since the gas will meet the water at a pressure presumably much greater than 1 atmosphere.
my questions are:
1.) how much pressure will they have to exert on the gas to get it down to this level? (remember, you must displace ALL of the water for the entire length of the tube going down)
and 2.) will this pressure be greater than that needed to liquify or solidify CO2?
maybe transporting large quantities of dry ice to the bottom of the ocean is the answer! surely it won't melt or sublime at such low temp and high pressure;)
It is a very well-known fact that the ocean plays a major part in the natural CO2 cycle of the earth. Where water is colder, CO2 is readily absorbed (CO2 absorbs into cold water, an comes out of hot water). This can either take place in regions where the water is chronically colder (e.g. the arctic) or where there is a lot of vertical turbulence going on, causing deeper, colder water to continually come in contact with the atmosphere.
The only thing that is new here is the fact that they want to stimulate further absorption by injecting it. The only problem with this is that they will have to pump it *very* deep to get to water that is cold enough to make this process as efficient as possible.
Even carrying this out with stunning efficiency, it is doubtful they will *ever* be able to pump enough CO2 out of the atmosphere to make a tiny dent globally... and NO, this will also never be enough to disrupt the highly buffered pH of the ocean.
I've been at 5 companies in the past 3 years,
one bank and 4 dot-coms in this area (philly suburb)
and I can definitely attest to this uptight, shitty attitude.
at my last dot-com, I was sent home for wearing
the copyleft.net dust puppy t-shirt (keep in
mind I am a senior UNIX architect, not some operator).
the reason--someone might be offended
by my shirt! it was explained to me that the
policy of "no writing or pictures on any t-shirt"
meant that no one could take offense to anthing.
what I found unbelievable was the fact that all
of the management types strolled around the
place wearing "Sun", "Veritas", etc polo shirts
without consequence.
[start sarcasm] lemme tell ya, I really do feel bad
that the company went under too [end sarcasm]
As a Senior UNIX Architect, this is the person I'm looking for in a co-op situation. If you give menial work and the person simply grinds through it without even wondering if it could be automated, then you know that this person lacks ingenuity/motivation/creativity/etc.
It seems like it's getting much worse out there when I go to movie theaters and the kids behind the counter cannot get "coke, half full with ice" right.
If you are one of the 2% of kids out there with an actual brain and a tiny amount of creativity, these co-ops would be breeze work because it's almost certain that the people with these same qualities above you on the ladder will recognize this. (Then there's always the possibility that you work at a company that is nearly devoid of real talent. Run for the door!)
please note that the 400MHz/4MB and 8MB
are pretty much standard issue on each and
every Ultra Enterprise 3500, 4500, 5500, 6500,
220R, 420R, 250, 450, and E10k
this isnt exactly what I would call "confined"!!
sounds more like and enterprise-wide product
line disaster to me.
they want you to believe that you must use
DHCP, but their tech let me know that each
and every box gets a static IP that is hard
coded in the DNS (yes I confirmed).
it is simple enough to set up a router/dns
box to use this single IP address and run NAT
for all private addresses inside. there is no way
they could ever know this is happening since
all traffic will come from the single assigned
IP address.
as long as you are doing it for the right reasons. if you are providing people with more secure alternatives that provide the same functions (ssh, scp, etc) then fine!
Telnet and ftp are inherently insecure protocols designed for an age where everyone knew everyone else on a single network. those days are gone now...
come on now! wake up and smell the corporate budget! The S/390 is a very awesome piece of hardware that is used and trusted by huge numbers of companies. a thing of the past, it is NOT.
we also need to keep in mind that Linus himself said that Linux was not suited well for the high-end server market, since it still does not scale well.
i love linux, but too many people are jumping on the bandwagon just to say they did, when they would be better off with a more robust and scaleable OS (Solaris, HPUX, AIX....)
some lady in screaming because her child didnt have legos when he was growing up because the family was too poor. now all of a sudden, this test is biased against the poor minorities of the country.
let's get serious here. the ONLY people who complain about unfair tests are the people who didnt do well (or the family and friends of said person).
my parents didnt even graduate high school and were not wealthy (the two biggest predictors) and i got a 1350 on the SAT.
there will never be a perfect test. the only "good" alternative is to base it on face to face interactions with the candidates (something few colleges could afford to do)--and then there would still be the argument that "the interviewer was biased".
what this author does not understand is that the real guru's are writing code with the simplest possible interface. if it can be a text-only interface, then why not? who needs "innovative, flashy looks" when a nice text-prompt will work just fine?
This author needs to go read some UNIX history, and then rewrite =/
i have been running linux for about as long as it has been around, and i really happen to like the fact that it did not used to have GUI's for everything under the sun. UNIX has never been ground for newbies and those weak at heart, and i honestly dont think that linux should be any different. i am NOT trying to be elite here either--i spent very long hours with my nose in books (and i still do, since i admin UNIX for a living now) to learn what makes *nix tick.
"if you make a tool that any moron can use, only morons will want to use it"
i for one will depart from the linux world if it keeps progressing towards the Mac world.

look at their most powerful 8mb cache enterprise

it's really too bad their case fans are so damned

can't wait until someone steals my phone...
wonder if they've thought of the implications.

It really does sound like they are prohibiting
the connection to work VPN's.
If this is truly the case then:
1) they are very stupid
2) they are begging people to switch to other
providers and/or xDSL

just my two cents
I just set up a second box at home by using
one of their unused addresses on my subnet.
easy enough (until someone reads a traffic log
or tries to use the hijacked IP)
color blind people can see color already...
they just cant distinguish between certain
hues.
there is absolutely no sense in making a gradual
transition (if one were available).
as long as you are doing it for the right
reasons. if you are providing people
with more secure alternatives that provide the
same functions (ssh, scp, etc) then
fine!
Telnet and ftp are inherently insecure protocols
designed for an age where everyone knew
everyone else on a single network. those days
are gone now...
Internet service providers should be encouraged, though not required, to maintain detailed records of what their users are doing online
this kind of crap makes me WANT to fake my name and other personal info when signing up for an ISP.
this might fall under the hearsay rule.
even police reports can fall under hearsay if
one party denies what is said within it.
come on now! wake up and smell the corporate
budget! The S/390 is a very awesome piece of
hardware that is used and trusted by huge numbers
of companies. a thing of the past, it is NOT.
they're talking about the server market.

some lady in screaming because her child didnt
have legos when he was growing up because the
family was too poor. now all of a sudden, this
test is biased against the poor minorities of
the country.

you're insinuating that *most* linux systems have
ONE partition? if this is really true, then the
average linux geek is not very bright.
look at any UNIX system. it is not a coincidence
that there is more than one partition.
i think you are wrong in your assumption about
*most* linux users, personally
why *Chinese* crackers? are they suddenly more
adept at creating viruses than crackers in any
other country??
heh =)
i have been running linux for about as long as it

I cannot get through any port besides 80 here. Real player is not possible here :(
maybe someone can post just the gist of it (if it's too long to transcribe?)
so Mandrake jumps to 7 and slackware jumps from 3 to 7....why not???

Microsoft thinks it can jump from 3.1 to 2000 in around a decade
