  1. Re:battery replacements? on Improved High-Performance Energy Storage · · Score: 2, Interesting

    But are they 10X as heavy, to provide the same power? Weight is more of an issue than size in a car.


    Energy and power density are usually given by mass (Joules/kg or Watts/kg).
  2. Re:battery replacements? on Improved High-Performance Energy Storage · · Score: 2, Informative

    Don't get too excited. They're still about an order of magnitude away from lithium ion batteries. The power power density and durability are much better, but that doesn't mean much when it has to be 10 times as big.

    Is a website the best place to discover that your DNA doesn't match any of your close relatives, as you were expecting it to - that your parents are not your natural parents and you were adopted?


    Ancestry.com is the Jerry Springer of the internet.
  4. Re:What's the big deal.. on Economic Analysis of Toilet Seat Position · · Score: 2, Insightful

    This is becoming such a problem at my workspace that I now go use the toilet where mostly women use it, instead of the one close to me where mostly men use it.

    That may work in a bathroom that isn't used by strangers. Not in a public restroom, though. Have you ever been in a public women's toilet stall? They're worse than men. Ask a woman about it, and she'll explain that some women "hover" over the seat. They have basically no directional control, which means the seat gets soaked. Nobody's gonna sit on a wet seat, so the next woman has to hover, too. Don't ask me why they can't put the seat up. I'm guessing it's a matter of principle.

  5. Re:Intelligent Drivers on Hybrid Cars No Better than 'Intelligent' Cars · · Score: 1

    What we really need are intelligent drivers. You know, the ones that don't drive 20 over the speed limit, don't tailgate, keep their cars in tune and the tires properly filled.


    Tailgating drastically improves efficiency. Of course, the crashes cut that back a bit. But I see a lot more tailgaters than accident-induced traffic jams. Hard to say which one would have a bigger impact.

    It's not that the individual principles are not understood; they are. Rather it's how to put all of it together in such a way that it gives us the right answer. This is most certainly NOT the same as not understanding E&M! Sheesh!


    The corona is a few hundred thousand miles away from any fusion, with dense plasma in between. I think it's safe to model them separately. And the lack of understanding of E&M is in the post. "Also conspicuously absent from the press releases is the conclusion that the sun's corona is so-dominated by electric and magnetic fields because it is a plasma."
  8. Re:Oblig. on Cooler Silicon Lasers Via Energy Harvesting · · Score: 1

    Don't forget the obligatory reference to simply powering the laser with frozen nitrogen, to simultaneously power it and keep it cool and pop a ton of popcorn from the stratosphere.


    Um, it was frozen bromine in an argon matrix. Liquid nitrogen would have to be frozen in helium, which just doesn't make sense.

    That's an optical frequency. Well, UV, but still, totally different from what they're talking about. Your example has to do with electronic states of matter. They're talking about circuitry.

    I agree that it's a good thing, but it's really surprising, especially considering Take Two's money problems. It seems like there would be a lot of money involved in getting a song on a short playlist for a big game like this. I can't imagine why they would pass it up.

    An exclusivity contract with Coca Cola apparently results in there being only Coke available on that campus.

    Georgia Tech has the same deal. We had the only Pizza Hut in the world that served Coke products (Pizza Hut was owned by Pepsi). It may still be the only one. Doesn't make it any cheaper, though. It's up to $1.40 for a bottle now. The difference all goes to the school.

    They've also given credit for the original work. Between the donation box and the second video it says, "(Layout provided by Mike Industries.)" with a link to his site. I figured they would just find another layout and pretend this never happened. That was a much more dignified response than I expected.

  15. Re:Toxicity based on what? on Genetically Modified Maize Is Toxic — Greenpeace · · Score: 1

    If I remember correctly, Monsanto modified soybeans and corn to be "RoundUp Ready" as they called it. Basically they GE'd the plants so that they would not be affected by Monsanto's RoundUp pesticide, allowing farmers to spray their whole field with the pesticide and leave their crops untouched. So I would venture to say that in order to make these plants resistant, there is probably something being produced by them that is not entirely natural.

    Those plants weren't "GE'd." They were BRED to be herbicide resistant. No physical modification of genes was involved.
  16. Re:Apples and oranges on Prototype Telescopes Complete Key Test · · Score: 2, Informative

    Except that one is a radio telescope and one is an optical telescope.

    So what? Stars and other black bodies radiate in both visible and microwave. If you're trying to resolve nearby objects (like binary stars or planetary systems), either one will work. Resolution is resolution. And besides, the angle resolved by a telescope is proportional to wavelength, so that just makes it MORE impressive. This telescope has a better resolution than the Hubble, even though it's working with 1000 times the wavelength.

  20. Re:Make it (partially) refundable on Growth of E-Waste May Lead to National 'E-Fee' · · Score: 1

    If the fee is high enough (say, $10 or even $50), you will want to bring the dead equipment for (partial) refund to a place, which will gladly process it (paid for by the rest of the fee).

    Recycling should MAKE money. Maybe if they base the amount you get back on the ease of reclaiming the materials, it would encourage more responsible manufacturing. They could set up a rating system, like a 1-10 scale for a 10-100% rebate, or something similar. It might even encourage people to get rid of old equipment sooner (I know I keep a lot of old crap laying around just in case I need it), so it should be easy to get the manufacturers involved.

    This is just a 'feature' similar to the one in Firefox that automatically performs a google search on things you enter into the URL bar if they aren't valid addresses

    That's not true. If it actually looks like an address to Firefox (i.e. it has a period in it and no spaces), then you get a "Server not found" page with the "Try Again" button. The important thing (to me, at least) is that Firefox leaves the url alone when this happens, so you can just correct your mistake and hit enter. IE makes you delete the long address they put in there and start over.

  23. Re:but but but but... on Congress Hears From Muzzled Scientists · · Score: 1

    Don't be silly. You are wasting your time with trivial energy use items while you probably have other multi-KW items that consume vastly more power in your house. For example, I have electric heating, a refrigerator, a microwave, and an oven which vastly outpower my electricity usage from light bulbs (and we haven't even gotten to the argument where I point out that in the winter the end result of the electricity used to power your light bulbs is heat which will cause no effect on your energy usage if you happen to own a thermostat with electric heating).

    I don't disagree with you in general, but you probably spend more on lighting than your refrigerator, microwave, and oven combined. Unless your refrigerator is 30 years old or you leave the door open all day, it probably averages much less than 100W. Microwaves and ovens use even less for most people. Light bulbs don't pull as much power, but they run at full power for extended periods, and most people like to keep their houses pretty well lit.

    And the decrease in your heating in the winter is probably more than offset by air conditioning in the summer, because unless I'm mistaken, heating systems are generally more efficient than cooling systems.
