    That's not good enough, cell phones never completely turn off. Pretty much all cell phones in the last 5-10 years are capable of remote power-on.

    In fact, most PCs with a built-in network card are capable of this as well. It's called a "magic packet", and it allows you to remote power-on a PC if you know the subnet it is on and the mac address.

    It can be disabled in the bios for PCs, but the cell phone version (it's obviously not the "magic packet" system for PCs) I don't think can be.

    What you need is a Faraday cage (a small bag will do), and to remove the battery (nothing can power it on after that).

    That is actually the procedure the S.S. uses, it's just not all agencies were as informed of the policy as others.

    If your conditions are "loss of signal" then you'll be wiping your phone an awful lot. That's all a Faraday cage is going to do - cut off the signal.

    Battery removal is also not something that can not be worked around without installing intrusion detection for the case. That's some significant modding, but is plausible.

    Assuming your wipe conditions are only something like a certain time without connection (which is more reasonable), if they pull the battery quickly enough you still won't stop it.

    Is anyone else getting concerned?

    Yes, everyone is concerned.

    If even 1% of that is oil, then we are totally fucked. Hopefully it's less than 0.01%.

    It's a very low percentage of oil, and it's in an emulsion, which is why it's 300 feet deep instead of an inch deep. It must be almost all water or it would not be heavy enough to occupy the top 300 feet of ocean water. You should be able to calculate the density of the emulsion Based on how deep it is able to remain in the water. Seawater has a density of 1021kg/m3, and gassy crude oil like the stuff in this spill generally has a density of 700-800 kg/m3. Pure crude is closer to 900 kg/m3. In order for the emulsion to stay so low in the water it is probably over 1010kg/m3, at least. If that's a good estimate for a density that would allow the oil to sink that low, then there are 11kg of oil per cubic meter in that water, which is in the 1% range. If the density needs to be higher to float that low, then there will be proportionately less oil in the water.

    However, if you calculate from the surface slick itself, you have 3650 sq miles of slick (as of Friday). And based on a chart of oil-thickness-to-color, you could say that the oil slick is 50 micrometers thick. This equates to 125 million gallons of pure oil just on the surface.

    I can't get the same numbers you got. I'm assuming you multiplied 3650 square miles by 1609 to get square meters, which is 5.87 million square meters. You then multiply by 50 microns to get cubic meters of oil, no? I get 293.5 cubic meters, which at 264 gallons per cubic meter is 77,500 gallons, or 1,844 barrels on the surface. This is in line with the idea that the vast majority of the oil is under water.

    Do you see the problem with trying to estimate the amount of oil that is spilling? It's freakin hard, and depending on what assumptions you use (and you have to use some assumptions) you get wildly varying figures.

    To illustrate my point, 5,000,000 gallons per day on the surface requires 120,000 barrels per day be pouring out just to equal the surface volume, yet there is many times more oil below the surface. Oil wells simply do not flow that fast, it would be the world's most profitable well by a wide margine. The average flow rate of wells in the gulf is 1600 barrels per day. Assuming this well is a real gusher, the flow rate might be up in the 40,000-50,000 barrels per day range. That's still an incredibly high flow for an oil well.

    Simple logic and a little knowledge of how oil wells work, and normal flows and the like would make you extremely skeptical of the very high figures being thrown around.

    In other words, when your estimations give you figures that are outside the expected norm by several orders of magnitude, you should probably re-examine your assumptions.

    Because every figure he gave was wrong.

    The casing pipe (the pipe you can see) is 21 inches in diameter, not 5 feet. The borehole (the hole that was actually drilled down to the reservoir, which you can't see) is 9 inches in diameter.

    The pressure is easily calculated - 45 psi per 100 feet of water, and 100psi per 100 feet of sedimentary rock. 5,000 feet of water gives you 2250 psi, and 11,000 feet of rock give you 11,000psi. Total pressure on the reservoir is therefore 13,250psi, with the pressure differential between the two ends of the borehole at 11,000psi.

    However, you can't just calculate that out with the density of crude oil to get the actual flow rate, and therefor the pressure, coming out of the pipe, because you don't know the gas to oil ratio of the oil or the porosity of the reservoir rock, which affect how fast the oil flows and how dense it is, which determines the force it exerts as it exits the pipe.

    This is why I call bullshit on so called experts who claim to have calculated the flow accurately. Visual calculation methods cannot be made accurately because of the lack of information about the gas to oil ratio - one 50k-100k visual based estimate I read assumes a GOR of zero (no gas), which is absurd, the oil at 150 degrees (the temp of the oil in the reservoir) and 13,000+ psi can hold a crapload of gas in suspension, which could easily make the visual estimate off by 50% or more. This is because as the pressure drops on the way up the borehole, the gas comes out of suspension and expands, causing the flow to increase dramatically but the ratio of oil by volume to gas decreases dramatically as well. The result is what appears to be a massive gusher of an oil leak that is actually mostly gas.

    Non-visual based calculations lack even more critical information about the composition of the oil that are necessary to make accurate calculations, like the porosity of the rock, the GOR again, and whether or not there are any obstructions that inhibit the flow.

    Frankly I'm very skeptical of anything over 30,000 barrels a day, that's one hell of a high flowing oil well as it is. 50,000 barrels a day I'm extremely skeptical of, and I dismiss anything more than that out of hand as virtually impossible. Oil wells simply don't flow that fast.

    It's a 5ft diameter hole, and the oil is coming out at something like 150,000 PSI.

    Holy shit, where do you ignorant people get your information?

    The casing is 21 inches in diameter, the borehole is 9 inches in diameter. The borehole is the limiting factor, but neither one of them are 5 feet in diameter. There is no drill rig on earth that drills a hole that big.

    As for PSI, it's easily calculated. Standard figures (based on specific gravity) are 45psi per 100ft of water, and 100psi per 100 feet of sedimentary rock.

    That means the pressure at seafloor (about 5,000 feet) is roughly 2250psi. At the top of the reservoir (an additional 11,000 feet) it's roughly 13,250psi.

    There is no 150,000psi, you would literally have a geyser of oil shooting out of the sea at those pressures.

    Now, that said, an 11,000psi pressure differential is nothing to sneeze at, but the question of flow is further confused by factors such as the porosity of the reservoir rock, the amount of gas mixed in solution with the oil (which comes out immediately at the pressure drop - it's like shaking a soda bottle and opening the lid), which influences the rate of flow (more gas means more flow) as well as the actual amount of oil that comes out (more gas means less oil by volume).

    Basically, plugging the hole is exactly what they've done, but the pressures are too great to simply push something against it. For one thing, the pipe is bent sideways, and under water you have a complete lack of leverage for generating any kind of horizontal pressure. So what they have done is attach the siphoning rig to a plug, and they are going to try to use suction to generate the necessary pressures to stop the leak.

    The siphon is already in place, they won't know how effective it will be until they ramp it up to full speed. They can't just flip the switch, or hydrates would form (oil and water binding to form solids) which would plug the pipe. They expect to have the leak under control some time next week.

    Maybe you aren't keeping up with the news - current estimates based on actual observations of the oil flowing out of the hole by people with no idea of critical factors like the gas to oil ratio, porosity of the reservoir rock, potential obstructions in the shaft is 50,000 barrels a day, making it worse than Ixtoc 1's peak flow rate (the number you gave).

    There, fixed that for you.

    An uninformed estimate is an uninformed estimate, no matter how much you try to make it sound otherwise. This is exactly the same problem BP has with their estimate, which is why they say it's impossible to accurately measure the flow of the well and chose the lowest figure they could get away with. They are right, and these "expert" figures are no more accurate than BP's figures, for all the same reasons.

    Frankly, a well naturally pushing 50,000 barrels per day is an extreme gusher, and is very rare. The average production of active wells in the gulf is 1600 barrels per day. I find it highly unlikely that this well is pushing out 50,000 barrels per day, but 5,000 seems like a real lowball estimate. A deep sea well wouldn't be profitable at that rate, and though there are plenty of ways to increase the flow of a well, you usually reserve them for after the natural pressure has dropped to the point that it won't push up to the surface adequately on its own. I'd be a lot more willing to believe 15,000-20,000 barrels a day until more accurate measurements can be made. 50,000 barrels is pretty out there.

    Protons are protons you fucking idiot

    I think you mean photons, there aren't any protons released by the sun's fusion reaction, it is extremely efficient in that regard, whereas the fission we use tosses protons all over the place. The radiation the sun produces is in the form of electromagnetic waves, which can still be extremely nasty, but the vast majority of the harmful stuff is deflected by Earth's magnetic field, along with any particulate matter from the solar wind.

    The vast majority of radiation from the sun that reaches the earth is non-ionizing radiation. Very little ionizing radiation makes it to the surface. Also, the fusion process of the sun produces a lot less residual ionizing radiation than the fission process we use on earth.

    The majority of radiation emitted close to a nuclear reactor (i.e. practically touching spent fuel rods and the like) is ionizing radiation. Ionizing radiation is very high energy and strips electrons from atoms (hence the "ionizing" part). This does very bad things to living organisms.

    There are actually pretty huge differences between radiation from the Sun (as far as what hits the earth) and radiation from a nuclear reactor if you ever managed to get close enough to be exposed to such radiation.

    Oil seeps naturally into the Gulf of Mexico at a rate of about 22 million barrels per year.

    If you use the doom and gloom "expert" estimates of 50,000 barrels a day non-stop, in a year this spill would not be able to match it. The truth of the matter is it's probably somewhere between the 5,000 barrels BP gives (probably the most conservative estimate they felt they could get away with) and the 50,000 barrels a day which, frankly, is one hell of a gusher for an oil well. The average flow rate for a Gulf of Mexico oil rig is 1600 barrels per day. You expect newly drilled wells to be significantly higher, and for this particular well to be profitable it would need to produce a minimum of 13,000 barrels per day. A safe guess is that BP was expecting to get more than 20,000 barrels a day from this well, but I could not tell you how that translates to the flow rate of a broken off pipe flowing freely at the bottom of the ocean.

    Since recent efforts to siphon the well seem to be going well, as it stands today you can expect that the spill will likely be under control (as in, no longer leaking) in the next couple of weeks, with a permanent solution to cap the well in the next few months.

    To relate it to the Exxon Valdez oil spill, the vast majority of the spill affected region bounced back almost completely within a year - in fact, one of the biggest impacts on the eco-system was the fact that fishers took a season off for fear of the oil, and the fisheries became over populated, which damaged fish populations for several years after. The oil itself had zero impact on the fish. You can still find small amounts of Exxon oil in some areas, but there is no measurable environmental impact that has lingered.
