  1. Re:Interesting, but not new on Electric Car Faster Than A Ferrari or Porsche · · Score: 1

    A simple gear system can have a 99% efficiency. That high an efficiency in a generator-motor system is in the difficult-to-impossible range. It requires low current densities and low magnetic densities, which are achieved by using high voltages, thick, heavy wires, and thick, heavy magnetic circuits. Particularly important is the word heavy; more mass reduces the overall efficiency of the transportation system.

  2. Re:Locomotives on Electric Car Faster Than A Ferrari or Porsche · · Score: 1
    Locomotives are not only very heavy, they have to be heavy to provide enough pulling force. Steel wheels on steel track have a fairly low coefficient of friction, low enough that a little oil on the tracks has caused many deaths. Engine to generator to electric motor is heavy and expensive, and to a first-order approximation, no railroader cares.

    In automobiles, a Prius-like scheme with a differential joining the engine to the electric motor is substantially lighter and less expensive.

    With some battery technologies, recharge time is limited by heating. If you can supply cold water to appropriately designed batteries, recharge time can be considerably reduced.

    Avoiding bad practices and bad substances reduces the likelihood of cancer. Eating well and using the right supplements substantially reduces the likelihood of cancer. This works because we do, if fact, know where a lot of cancer comes from and how to help prevent it. It's like driving carefully in a well-designed, carefully maintained car. This is a private issue because only an individual can act wisely. "Public" healthcare inevitably involves stealing from those who take care of themselves.

  7. Re:Extensions on Mozilla Firefox 1.5.0.3 Released · · Score: 1
    If the extension is actually still good for the new version, but has a specific version limit that prevents it from installing, the install file for that extension can be text-edited to work. I've used this with statusbar clock.

    If all that's available is a .jar file for the extension, I've read that it can be decompressed with unzip, edited, and recompressed; and then it will work.

    One of the major selling points of a HLL is that it is less verbose. I want to put a concept on a line, not a page. This makes it easier to write, easier to maintain.

  10. Re:Quality Assurance? on Flawed AMD Chip Can Lead To Data Corruption · · Score: 1
    "At least this bug was found. How many more like it are there, but we simply don't have the proper trace to find it?"

    Hard to say. This is a design margin thing, depending upon worst case conditions plus localized heating, and localized heating (AFAIK) isn't generally modeled. Writing test vectors to find all logic errors is difficult, unpleasant, and labor intensive work. Even if software identifies the worst case path, it won't account for localized heating.

    I'd guess there are other problems out there like this, but they generally can be avoided by staying well away from maximum operating conditions: keep your chip cool and within the specified voltage range, and don't overclock.

    Just imagine, if this is allowed, pretty soon there will be two-wheeled cars with no bodies. Just like a bicycle with a motor. Why, I bet they'd call them "motorcycles" and we'd have to have special roads for them, too.

    "I figure that in any country, if the land hasn't been sold, then the land is owned by the government."

    True, but...

    ...Government ownership almost never results in the best use of the property.

    ...Government ownership seldom comes about honestly; it is usually the result of some sort of theft.

    ...Government ownership tends to be irreversible. Vast stretches of the western U.S. are owned by the federal government, and are unavailable for purchase for any reason whatsoever.

    ...Government ownership promotes corruption. Complaints about the forest service and the BLM are commonplace.

    I live about a half mile from a ski slope. The snow making machines don't even register on my sound level meter when I'm outside (so they're below 60 dB), yet they're still irritating inside when I'm trying to sleep. I'd imagine that windmills would have a more pleasant sound (a rhythmic whoosh instead of a midrange buzz).

    Note that the complainers against windmills don't state the distance at which the 102 dB was measured, and it's for sure that they weren't citing best available technology.

    Displays are being made with LEDs; they're used at sporting events and they're expensive. Look up Daktronics.

    For desktop displays, most common LED chips are too large to make a good display (10 mil squares) and would require too many chips and too much labor to assemble a cost-effective display. Wafers containing a large number of pixels have problems with dead pixels and poor luminous uniformity (I'm guessing here.) OLEDs have the potential to be printed on an inexpensive substrate.
