The process of making lime generates CO2, but adding the lime to seawater absorbs almost twice as much CO2. The overall process is therefore 'carbon negative'.
There is a little bit of truth in this, but not much, and it cancels itself out eventually.
So where do you get lime (calcium oxide/hydroxide)? From heating limestone (calcium carbonate) which releases CO2. CaCO3->CaO + CO2
Then you hydrate it:
CaO + H2O-> Ca(OH)2
And add it to water. What happens is it absorbs 2 carbon dioxide, initially - and if the pH is right: Ca(OH)2 + 2CO2->Ca(HCO3)2 that is calcium bicarbonate.
I guess this is why they say "it absorbs twice as much CO2".
The problem with all that is, calcium bicarbonate is unstable and will eventually decompose, liberating back CO2:
Ca(HCO3)2->CaCO3 +H2O +CO2
And there you have it, all the CO2 is released (2 molecules in, 2 molecules out), and all you accomplished in the end is just moving the limestone from the mountains to the bottom of the ocean.
Mod parent up - I was about to post on the same lines. Looks like all the likely candidates contain gallium, and gallium is not known to play nice to other metals - corrodes them etc.
I'm anxiously awaiting the novel you'll be writing on the subject. Should make nice amateur Sci-Fi. (A lot) more on the side of Fi than of Sci, but that's OK.
You need the latest unreleased yet drivers for toe GTX2xx series, version 177.39. Then edit the nv4_disp.inf file and add an entry for device ID of 0611 (=8800GT). You will then be able to install the driver on the 8800GT. Next, install the new (also unreleased yet, but google is your friend) 8.06 software for PhysX. That's it.
Yes, it works on one card. I have enabled it on my 8800GT earlier today. The CUDA/PhysX layer gets time-sliced access to the card. Yes, it will drop framerates by about 10%.
OTOH if you have 2 cards, you can dedicate one to CUDA and one to rendering so there won't be a hit. The cards need to NOT be in SLI (if they're in SLI, the driver sees only one GPU, and it will time-slice it like it does with a single card). This is actually the preferred configuration.
That's biochemistry 101. You make them dependent of a chemical that doesn't exist in nature, so even if they get released (accidentally or otherwise) they can't sustain themselves in the wild and die off.
Score one for us. I've been receiving calls with spoofed CIDs for the past 3-4 months, including on my cell phone. Up to 8-10 calls a day, and nights too. About 2 months ago I filed a complaint with the FCC, not thinking it would help much. Yet about a month after that I received a notice that my complaint was being investigated, and the volume of calls dropped almost immediately. I still get 1-2 calls a day, not every day though. And at least they stopped calling my cell phone altogether. I wonder if these were the guys doing it, or maybe there are more cases down the pipeline.

The Cyberiad is accessible at any age.
Damn, even with preview...
the GTX2xx, not toe GTX2xx

You mean masers? They've been around for several decades.
No, you may want to check your FPU, because in fact it's 29.99178607283015423929907821484 years.
LOL. I still use WindowMaker. Lightweight, pretty, very appropriate for thin clients.
Thanks. But since you missed it, here's the sarcasm tag from the original post:

... not everyone on Earth has their own IPv4 address? Aaagh, my brain hurts!

How would an Improvised Explosive Device help things in this case?
We're dooooooooooooooooooo[catches breath]ooooooooooooooomed!
You're welcome to try. It's a Diesel - and Diesels may not be fast, but they have lots of torque.
Drats! I've been outed. Someone figured out why I was buying all those barrels of electrons, protons and neutrons.
FWIW, there are non-fuel-injected, carbeurated diesels. They're mainly in model airplanes
And they're wrongly called "diesel" as they don't work on the same P/V curve as a regular diesel.
Perhaps someone needs a $100M tax writeoff...
Now maybe Novell will have where to get their money from.
