    Not necessarily. If this new technology could eventually reach 15% efficiency, then it's still nothing particularly wonderful when you take into account the fact that some firms like Boeing Spectrolabs boast solar cells with efficiencies as high as 40%


    That's interesting. Are they claiming 40% efficiency based on <energy output per unit area of cell>/<insolation per unit area of cell>, which isn't very interesting, and kind of misleading, or 40% based on the energy per unit area of the entire device?

    Now that would be the holy grail of, at least, the entertainment industry, which as others have pointed out drives much of the quest for greater processing power.


    I really don't see how that's possible. The entire US film industry's gross receipts were only $10 billion last year. Microsoft's net income last year was $17 billion, and Microsoft is only ONE company in the tech industry.

    Intel, one of the major producers of the actual processing power had a net profit of nearly $7 billion.

    I think it's safe to say that the special effects industry far from a principle driver of processing speed advances.
  4. Re:Education on California Lawmaker Seeks Climate Change as part of Public Education · · Score: 2, Interesting

    Heh, Computational Fluid Dynamics is a complicated and diverse field. ALL CFD codes are characterized by the simplifying assumptions they make in order to actually have results in a time period where the results could potentially be useful. Further, the models aren't so much good as actual predictors, but as filters for more general theories: If the theory doesn't work in the model that uses its assumptions, then the it and/or the assumptions are wrong, or there are hidden assumptions which have not been characterized.

    The point of all this is that if a model reproduces "El Nino" it very likely was designed to. There are other effects which it will wildly mis characterize or miss entirely. The interesting option occurs when the model is designed to reproduce some other effect, and happens to reproduce "El Nino" as well. Then there is a lot of good work to be had determining if it offers real insight, or is just a fluke of the results.

    Ensemble averaging is bullshit. You can't just take a series of specialized models and tie them together and expect to get anything out of it but the original assumptions. Especially true as many models are descendants of other models, which will interfere with your weighting even more. What you can do is apply several different models to different domains and link them together. But the problem there is that the complexity makes it more difficult to determine what's really going on.

    No, the CVS price isn't $30/200 pages. That's the price of just the ink on certain HP printers that are really designed for home use. For a company with a lot of printing, you'd certainly want to do everything in-house on machines designed to actually print stuff, rather than machines designed to be able to print stuff occasionally.

    The needs are different. My point, and it's a little orthogonal since it mostly applies to inkjet color printers, is that the local drugstore can give you photo print which are both better quality and lower price than printing at home ("up to 200 pages" at 5% ink coverage, which is.. graphs? photos would be closer to 50% ink coverage). And since they're drugstores, they're convenient enough that they're a real option. So, what else are you printing from home that really needs color? And are you doing it frequently enough that it's worth it to sacrifice black-quality, cost per page, wasted ink, the ability to print circuit traces for PCB etching, and when the ink-dots finally trickle down to inkjets, security?

    So, as in TFA, you think the film making license to "The Lord of the Rings" universe for life+something is = approximately $65,000?
    No, I think it's worth more than zero dollars, although the actual amount due now definitely depends on the terms of the original contract and how much was paid up front for the rights.

    You have to have a saleable commodity before you can start talking about negotiating the price of that commodity. If New line could just take his work for free instead of negotiating a contract, they have a fiduciary responsibility to their shareholders to do just that.

    What doesn't make sense here, though, is that New Line's rights are set to expire soon, and the Tolkien estate has expressed a desire for Jackson to be the one to direct the Hobbit film. In other words, All he had to do was wait out New Line, and they'd write him into the next contract they negotiate with another studio.

    You hear this a lot, but it's actually a good thing. Not that they're not fully prepared for whatever the next conflict will be, but that they are prepared for tactics that have already been used: They shouldn't be caught off guard against things they know about.

    No, the energy in that plan doesn't come from the sea temp, it comes from the ballast. The thing you're depleting is the available buoyancy material, whether it be helium, air, or oil.

    For a closed-circuit buoyancy engine, you have to physically pump the buoyancy material around to get your change in density. This pumping is against whatever the ambient pressure is, so the deeper you allow it to drop, the more force you have to pump against to get your buoyancy back and return to the surface.

    Since you have to pump the same volume of material either way, against a force that depends on the depth , it takes more work to get your buoyancy back the deeper you go. This works whether do the pumping on the bottom with oil-bladders, or at the top with air bladders.

    I feel the same way about patent. If an inventor wants to monetize his invention, he should either develop it himself or license it to a company to develop. When he dies, it should become public domain.


    And that's why it's life +something. You can argue that the +something is too large, but it needs be non-zero (or an absolute right whose expiration is completely independent of the life of the creator) to mitigate the risk to the licensee that the idea they're paying for suddenly becomes worthless to them by virtue of being free to everyone else.

    Obviously, even with that risk, there is some value to the company to have the ability to produce things before other companies and whatnot. It's just that the risk modifies how much the company can pay the creator for his work. Compensation would have a substantial modifier due to the creator's health, rather than simply how much benefit his work is to society.
