  1. Re:Diesels already do this. on Mazda Claims 70 mpg For New Engine, No Hybrid Needed · · Score: 1

    Incorrect. Non-turbocharged diesels exist. Getting enough compression to allow the fuel to ignite is not the reason to use turbocharging.

    At low rpm, the turbo doesn't work anyway and you need to rely on compression ratio alone to get the fuel to ignite.

    That's nonsense.

    1. they have caught on very well, thank you very much, everywhere except the US, and that's because the US was slow in adopting the low-sulfur diesel fuel needed by modern diesels.

    2. if anything, the diesel will have longer gearing than the petrol version to take advantage of all that torque at low revs. Since turbochargers have become common on diesel engines sometime in the '80s, diesels have had easily enough power to cope with the most demanding driving conditions.

    I can produce more torque than a diesel engine with my hands and a long spanner

    That's a nonargument.

    Torque figures are just as useful as power figures for comparing cars, i.e. not very much. The meaningful items are the torque curve, which tells you how responsive the engine is over its operating range, and the power-to-weight ratio, which tells you what effect the engine will have in terms of accelleration.

    You're talking about turbo lag, which happens on any vehicle with a turbocharger, not just diesels.

  6. Re:Daddy what's a cassette? on Sony Discontinues the Walkman · · Score: 1

    Reel-to-reel != cassette. Reel-to-reel is the AEG Magnetophon system and all of its derivatives, where you have two reels that are placed on the machine separately, and you have to thread the tape manually from one reel to the other.

    Reel-to-reel decks were large and costly enough that I don't expect them to have been very popular for vinyl ripping. An 18 cm reel cost as much as an LP, iirc.

    Cassette tape decks were the instruments of the first large-scale music pirates.

    My point was more that writers often don't have the skills to produce a book that has a good layout and structure (for nonfiction, things like the breakdown into chapters, the index, etc.). There's more to writing a readable book than knowing where to find the 'save as PDF' feature.

    AIU, the Volt does not have a mechanical connection between the gas engine and the wheels. What everyone's so upset about is an electrical connection between the generator and the electric motor, allowing the gas engine to provide part of the current required for high-speed driving, instead of allowing the batteries to be depleted at a huge rate.

    I've heard of standard modal containers outfitted with plastic insets - sounds reasonable as the infrastructure to move them is well developed - but I've yet to see one.

    'Containers' that consist of a cylindrical steel tank with a container-shaped frame around them are common enough. Plastic insets are also available from e.g. SAI.
    That would leave you with 25-ton units which have to be unloaded one at a time, but would fit in standardized distribution channels. A tanker would be cheaper and faster to load and unload, but requires dedicated infrastructure.

  18. Re:The essence of hipsterism: on Word Processors — One Writer's Further Retreat · · Score: 2, Informative

    Mine is lighter than my geared bikes, and the mechanical efficiency is higher because the system is simpler -- so I can accelerate off the line a lot faster, making it preferable in stop-and-go traffic*.

    A lot faster than what? Someone who has left his bike in top gear when coming to a stop, and can't change down while stopped because he has derailleur gears? Acceleration depends on gearing more than on the last 10% of mechanical efficiency.

    Also, my mind boggles at the thought of not having brakes. When you rely on pedal resistance to brake, you have maybe 20% of the braking torque available compared to any set of halfdecent brakes. That's not just inconvenient, IMO it borders on the criminally negligent.

    Having a bit of experience with FM, I'm surprised to hear anyone describe it as 'terrible'. True, in FM9 the UI has taken a nosedive, but otherwise it's one of the best word processors I've ever seen. It's consistent, and crucially it can separate the layout from the content. To get anywhere near FM's level of quality, you'd have to rewrite Word from scratch.

    By that argument, the Colossus and contemporaries were just a logical evolution of the telephone exchange.

    I disagree. Babbage's ideas were out of the blue. So much so that in the 100 years following, no one working on the numerous calculator (and related) projects had the same idea. Babbage was working on a Turing-complete machine a century before Turing put that concept to paper.
