    And yet the poster to whom I responded still took the notion of so-called AI like what is in Her and called it "magic". Seems to me very much like if a technology is proposed that is beyond what we can understand, even if we know that it's supposed to be technology, is to still call it magic.

    That one can't be bothered to check the original story that was being referred to, when a link to it is right there in the story on the greencar website is hardly the fault of anyone but a person who is too lazy or indifferent to check said link.

    Well... creation *may* be falsifiable... it just may not be terribly practical to try and do so.

    I mean, assuming that the biblical account of creation were true, then man is supposedly at the summit of it all, and it stands to reason that nothing could ever really happen which would successfully annhilate mankind forever, since that would leave the universe without mankind to steward it. Therefore, if *ALL* of humanity were ever wiped out, and one did not actually face any supposed judgement day in the hereafter, then it's fairly hard to argue that the biblical account of creation has been shown to be false. The fact that nobody would be around to see it or appreciate it afterwards doesn't mean that it wouldn't have been disproven... and if some other species on earth rises up through evolution and develops intelligence (or an alien species equally unrelated to mankind), and they discover our existence and our beliefs through archeological research, they could realize that the notion we had was untrue because we were all wiped out.

    Notwithstanding, if a person ends up actually facing judgement day after supposedly dying, then that experience would probably lend a lot of credibility to the whole concept for that particular person as well.

    There is no such physical process as "upping the voltage"

    Sure there is... either you add more cells... or else you increase the charge density. The former comes at a cost of adding mass, the latter requires changing the chemistry of the battery for a better one, which may or may not be financial viable, and in extreme cases, not even necessarily physically possible. Either way, net energy that you get from the battery is proportional to its total charge content, which equals its charge density times its mass. Charge density is the fundamental property of the type of chemistry used in the battery, so it's convenient to use.

    Since stories like yours are not unheard of, I can't refute the possibility it may depend on the type of cartridge, but it does not seem to depend at all on the manufacturer, since what I describe happens with them with incredibly greater frequency. Personally, I would suggest that you should consider yourself very lucky. Not many get to enjoy having an inkjet printer that costs less in replacement cartridges per year than it would to replace.

    As for your suggestion that it does not happen where you work, bear in mind that at work, many people are liable to use a single printer, so it is less likely to be left idle for as long as a home printer may be. This will admittedly tend to give it much closer to its estimated page output, but at high volumes, it's rarely disputed that laser printing is still preferable to inkjet anyways.

    I actually wrote a review in my slashdot journal about the economies of color printing several years ago, if you'd care to read it... I don't know how many people actually read it (at least one did, since it was commented on), but it's still something worth thinking about, IMO. (It's now archived and can't be commented on, I'm afraid).

    Such conclusions are drawn only from hand-picked evidence, that conveniently ignores anything which does not fit the preconception that creation happened. Not terribly unlike moon landing hoax advocates, actually.

    Charge density always translates directly to energy density... if you up the voltage, for instance, but keep it at the same energy density, you can get more energy out of the system, but bear in mind that the extra work you can get from increased voltage doesn't come for free... to get that voltage out of the same charge density will still require that you add a corresponding amount of mass in the first place. You can, however, by increasing charge density, actually *increase* the voltage without necessarily adding more mass.

    Creationism shouldn't be taught not because it may be false but because it is not verifiable with evidence that we can examine today, like evolution seems to be.

    If that were the case, you would not get such a vast difference in number of pages printable with a cartridge the faster you use it after opening it. If you are printing only very occasionally, you will be printing noticeably fewer pages with it overall than if you had printed everything over a much shorter period. If your printer has been idle for even a week, you will probably need to clean the print heads just to get respectable quality... an action which all by itself uses between 10 and 20 typical pages worth of ink, and is simply wasted.

    We were told the mpg; not the size of the tank.

    This is actually a suprisingly apt analogy... you need to know both to know the actual distance you'll be able to trave, but if you can improve the mpg, then the exact same size tank will still carry your car farther, by a precisely proportional amount. It is, after all, mpg that is what car manufacturers talk about when trying to sell you a car... not just how many gallons the gas tank can hold.... because mpg is ultimately the more useful thing to know.

    The mpg, in to continue the car analogy, would be comparable to whatever the power demands were for the application you needed the electricity for. Higher power demand would be, in this case, comparable to a worse mpg rating.

  23. Re:Amp hours per kilogram on Powering Phones, PCs Using Sugar · · Score: 1

    The reason the potential difference is unlikely to be constant when comparing batteries of different chemistry is because the charge density storage is going to be different between them. The higher density storage medium can produce a higher voltage right out of the starting gate anyways. In practice, you will limit that voltage to whatever the application actually needs, however... and when you have more charge available, you can power the application for a longer period of time and thus will have provided more energy into the circuit.

    As you rightly point out... many CFL's don't actually last as long as they purport, so they can end up being more expensive than incandescents.

    Toner, however, really doesn't ever evaporate. Ink does.. leaving behind an unusable residue in the inkjet cartridge's compartment that will require replacing long before you've actually exhausted the raw material you originally purchased unless you are printing in high enough volume that evaporation is not an issue.

    But if you are printing in that high volume, then laser is *STILL* the preferred choice, because just comparing cost of cartridges and dividing by the number of pages you can optimally produce per cartridge, toner still ends up being less than a quarter of the cost of using ink.
