  1. No such thing as gigawatts per hour on Half of Germany's Power Supplied By Solar, Briefly · · Score: 2

    Unbelievably lame. There is no such unit as a "gigawatt per hour".

    You can't even be sure what this means, if anything.

  2. secret chem trail organization excels at security on Why Weather Control Conspiracy Theories Are Scientifically Ludicrous · · Score: 3, Funny

    The NSA should hire the SCTO (secret chem trail organization) to handle their security. No more leaks to worry about. Show the NSA how to control information right.

    It is clear that the SCTO maintains a global fleet of thousands of specially modified tanker aircraft for 24/7 operations. There is a small army of technicians, mechanics and pilots. They skillfully manage extreme logistical challenges to safely manufacture, store, and distribute all the millions of tons of chemicals. All in secret. Not one whistle-blower. Not one crash or chemical spill. Not one photo or chemical sample has leaked.

  3. H2 is not energy source, not safe, not efficient on Hydrogen Powered Cars · · Score: 1

    >>Hydrogen is NOT abundant in nature. The only source of it is water.

    >Water, eh? Not much of that around.

    The hydrogen in water is tightly bound. You have to add energy to split the water. So hydrogen is not a source of energy, it is merely an energy carrier. Let me repeat that.

    HYDROGEN IS NOT A SOURCE OF ENERGY, IT IS MERELY AN ENERGY CARRIER.

    >>When you move from an internal combustion engine with it's small size and all those moving parts up to a big, ole power plant you can get an order of magnitude or so more power out of the same amount of fossil fuel.
    >>

    This is just not correct. I think at most you could gain a factor of 2. And I believe that this would be less than the losses involved in *making* hydrogen, *compressing* hydrogen, and then *using* hydrogen.

    Anyhow, electrolysis is an expensive way to make hydrogen. It is better to skip the electricity step and use a chemical process to go straight from natural gas to hydrogen. By expensive, I mean using more fuel, and making more pollution.

    Also you ought to check out the NASA hydrogen safety site. Hydrogen has a low energy of ignition, and a wide flammability range in the fuel to air ratio. By both of these measures hydrogen is more dangerous than gasoline.

    The gasoline tank explosions that you see on TV after every collision are a gross exaggeration and not representative of gasoline safety.

  4. Re:Hydrogen on Hitachi Folds, Rambus Keeps On Rolling · · Score: 1

    Pay close attention:

    HYDROGEN IS NOT A PRIMARY FUEL

    HYDROGEN IS ONLY AN ENERGY CARRIER

    If you use hydrogen to run your car (instead of gasoline), you end up producing more pollution (in order to make the hydrogen) and spending a lot more money. And there is no safe way to store and handle hydrogen. It is very explosive over a wide range of concentrations.

  5. lot of misinformation on Internet Access While Sailing? · · Score: 1

    There is no mystery here, and no great difficulty. All you have to do is drop by the nearest marina or yacht club and look at the magazines that are lying around. There are lots of ads for commercial email services for people on the high seas.

    Some work by means of HF SSB marine radio telephone, (you can get a license by paying a fee)with a smart computer box doing audio modulation. It is a very specialized modem. The data rate is very slow, just a few bits per second. But it works world wide, and is very robust in the presence of interference. When you are spending months sailing across the ocean, it doesn't matter if your computer controlled radio has to grind all day to download a small email.

    But if you want web browsing then you have to go with a much more expensive solution, like INMARSAT.

  6. Fight ! You could win on the merits. on Microsoft Asks Slashdot To Remove Readers' Posts · · Score: 1

    As I understand it, Microsoft is complaining that you are publishing a copy of a technical manual.

    Assuming that this is actually the case, I think you have a chance of winning on the merits.

    The copyright act protects the expression of ideas that are fixed in a tangible medium.

    Whole classes of ideas are excluded. You can't copyright something that is entirely utilitarian in nature.

    It is the expression that is protected, not the idea itself.

    Works that combine expressive and functional aspects are more weakly protected that those that are purely expressive. So a tech manual gets considerably less protection than a love song.

    The "fair use" provision does not have a size limit. The amount that can be copied under "fair use" depends on the nature of the work, and what is needed to accomplish the "fair use" goals. You have to balance the competing interests of the author and the public.

    So, considering that (1)the underlying idea, which is described by the work, is entirely utilitarian, and (2)that the work is a fusion of both functional and expressive aspects, and (3)that the work is derived from a public standard, and (4) you can't go down to the local book store and buy a copy of the work, and (5) the underlying product is a tool that Microsoft is using to further an illegal monopoly, and (6)that the whole work is necessary for the discussion of a subject as vital as the security of the global internet, and (7)that the copies of the work are being provided without charging a fee, then it seems like you could prevail.

    Go for it !

    The upside is great. You get lots of good publicity as long as the matter is before the courts. And you might prevail.

    The downside is not bad. You are acting in good faith, within the law, to protect your rights as you see them. There is no possibility of a monetary penalty. Now, in order to maintain your good faith you will probably have to remove the material in the short term. However, even this can be turned to a tactical public relations advantage.

    Of course, win or lose, you have to have money to pay the lawyers. But, it would be hard to find a more popular cause with which to attract donations. And ,if at some point you run out of money, you can always quit.

    CONCLUSION
    Upside potential: HUGE
    Downside risk: NONE

    GO FOR IT !

  7. Re:IO? on New Photos of Io · · Score: 1

    The four Galilean moons of Jupiter (Callisto, Ganymede, Europa, and Io) are very famous. They are named after characters of Greek mythology. You can find them in almost any dictionary.

    They were the first objects discovered that clearly did not revolve around the Earth. This was a big deal at the time. Galileo got in trouble for pursuing this idea to its logical conclusion.

    These moons are used as settings for numerous science fiction novels, and Star Trek, and they were on Nova just last week.

  8. sun angle in photo? right or left? on New Photos of Io · · Score: 1

    According to the NASA statment, the sun is coming from the right of the photo. But it sure looks to me as if the sun is coming from the left.

    What do you guys think?

  9. Way off base ! on ENIAC, the forgotten story · · Score: 1

    This author focuses too much on a hook for his story and not enough on the facts.

    Yes, E&M built a computer. With a ton of government money, but with no new ideas. The only "first" is the use of vaccuum tubes. A logic switch is a logic switch. It does not matter much if you use a relay, a vacuum tube, or a transistor.

    In fact, years later, the patents were declared invalid. E&M used designs from Atanasoff without attribution.

    And the overall architecture was that of VonNeuman.

  10. Ways to get at the unencoded data... on RIAA Plans to Allow Portable MP3 Players · · Score: 1

    It seems to me that it would not be too difficult to modify the sound card driver in Linux so that it makes a copy in a file of all the bits that get sent to the sound card.

    So if you have a legal player program, it is possible to get access to the decoded bitstream, and then to reformat any way you want and to copy at will.

    There may be other ways to get at a bitstream in an open format. Don't some PC speakers accept digital sound over USB? Well USB is a well defined format, and I am confident that someone soon will make some special "line monitor" or "network analyzer" software that lets you capture data off the USB cable.

    I don't see any way to get around these scenarios.
