Gulf Gusher Worst Case Scenario 799

An anonymous reader writes "Here's a listing of several scientific and economic guides for estimating the volume of flow of the leak in the Gulf of Mexico erupting at a rate of somewhere around 1 million barrels per day. A new video released shows the largest hole spewing oil and natural gas from an aperture 5 feet in diameter at a rate of approximately 4 barrels per second. The oil coming up through 5,000 feet of pressurized salt water acts like a fractionating column. What you see on the surface is just around 20% of what is actually underneath the approximate 9,000 square miles of slick on the surface. The natural gas doesn't bubble to the top but gets suspended in the water, depleting the oxygen from the water. BP would not have been celebrating with execs on the rig just prior to the explosion if it had not been capable producing at least 500,000 barrels per day — under control. If the rock gave way due to the out-of-control gushing (or due to a nuke being detonated to contain the leak), it could become a Yellowstone Caldera type event, except from below a mile of sea, with a 1/4-mile opening, with up to 150,000 psi of oil and natural gas behind it, from a reserve nearly as large as the Gulf of Mexico containing trillions of barrels of oil. That would be an Earth extinction event."

Scammer Plants a Fake ATM At Defcon 17 394

Groo Wanderer writes "Normally, a well-crafted fake ATM would skim a lot of card information before it was noticed, if it was ever noticed at all. Because it is safer for the criminals and harder to prosecute, financial crimes like this are spreading fast. If you are smart, you don't try to pull one off in the middle of a computer security convention where the attendees are very good at spotting such scams. That said, some not-so-bright criminal tried to plant a fake ATM at Defcon. He now has one less fake ATM and a whole lot of investigators on his tail."
It's funny.  Laugh.

The Commodore 64 vs. the iPhone 3G S 238

Harry writes "The unfortunate news about Apple rejecting a Commodore 64 emulator from the iPhone App Store inspired me to compare the C64 to the new iPhone 3G S, in more detail than any rational person is likely to compare them, ever again. If nothing else, it's a snapshot of just how far technology has come since the C64's release in August of 1982."

Comment pressure (Score 1) 190

Partial Pressure of O2 is what's important.
If you have more oxygen, you need less pressure to get enough into your bloodstream. Earth's atmosphere is about 21% oxygen. If you could get the air in the habitat to 50% oxygen, you would need that much less pressure. (Of course, people traveling back and forth between the habitat and Earth might have some problems with the pressure differences)
