    Compare the typical 12 gauge domestic power wire for (125 VAC @15 amps) in your house to a jumper cable for your car for (13.8 VDC @135 Amps) and you would see why.

  2. Re:Edison reaching out from beyond the grave on Are Data Centers Finally Ready For DC Power? · · Score: 2

    The typical computer power supply and almost everything else anymore uses a rather efficient switching power supply, it takes the input power, rectifies it, runs it through a transformer by switching the DC on and off at high frequency, then rectifying the output from the transformer to supply the rest of the computer. The power supplies change from 115 VAC to 230 VAC input by a simple switch, the 230 VAC , which has a peak to peak voltage of 325 volts, just a stones throw from 380 VDC. The only reason that switching power supplies aren't used on DC is because one side of the input rectifier bridge will probably burn out from not having a rest cycle to cool off. Beef up that bridge rectifier and the power supply will not care what the input frequency is. It would be trivial to convert power supplies to 380 VDC.

    Darik's Boot and Nuke ("DBAN") is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.
    DBAN is a means of ensuring due diligence in computer recycling, a way of preventing identity theft if you want to sell a computer, and a good way to totally clean a Microsoft Windows installation of viruses and spyware. DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.
    DBAN is a free software product that can be used at home or in a business at zero cost. The only official place to obtain DBAN is by download at this web site. We do not sell DBAN media.

    The IPCC's 2035 statement was an error that they have admitted. That particular statement never got vetted by a glaciologist who would have known it was ridiculous. It was basically on the level of a typographical error, not a scientific error.

    I would consider that in it's self to be symptomatic of a lack of scientific rigor, the IPCC reports have numerous examples of NGO's inserting their propaganda into it that isn't peer reviewed. How does one get to be an editor of the IPCC, popularity contest?

    At that time I Could go outside the door and jump on our snowmobile and go for a ride, In High school I worked in the tow both at a ski area for spending money and free skiing and it was much colder and snowier in the 1960 and 1970 than it was in the 1980 and 90's. It was much more plausible in the public's mind that some kind of mini ice age was coming. In the nineties, if I wanted to go from a snowmobile ride I had to drive 200 miles north to find decent snow and this global warming was much more plausible in the public's mind. Guess what kiddies the climate has a quasi-periodic temperature oscillations of 30, 60 and 120 years; the sun has a sun-spot cycle of 22 years and everything is in a down cycle so expect it to be cool for a while.

    Maybe it's a matter of is zero the first number or is one, if the clock is starting when the neutrinos enter the hadron stop but the yardstick is measuring from the outside of the hadron stop, then the 60 nS difference would just about work out to the excepted speed of light.

    MINOS as it now exists can only check the 730 km trip from CERN to Italy, not the 18-metre (60-light-nanosecond) trip across the iron "hadron stop" at the end of the decay tunnel at CERN, which may be at the heart of the result. This is because MINOS uses a matched near detector / far detector layout, whereas OPERA measures from the original protons (which are "upstream" from the hadron stop).
