  1. Re:Genetics? No way on Humans Hardwired to Believe in Supernatural Deity? · · Score: 1
    Actually, it's more often the mother who attempts to instill religion into the young. It's their tool to gain dominance over their physical (and often mental) superior. Female children tend to be more eager to please their parents, and thus are more receptive to religious brainwashing. Thus religion is passed on, generation to generation, through the women.

    The independent thinker is more likely to be a man. Both independent thinking and rebelliousness tend to be properties of men; both tend against religion.

  2. Re:Unresearched side effects. on Scotland Building Wave Power Farms · · Score: 1

    Waves are made by wind; increased wave energy comes from decreased wind energy. Extracting this energy from waves will cool the coastal ocean, although this will be offset somewhat by decreased evaporation from waves hitting the shore. Since we are already using the ocean as a heat sink, this will have a compensating effect, driving us closer to a "natural" condition.

    LED is using 1% of the power and has 1000x the lifespan
    Liar.

    Incandescents have typical power efficiencies of 5%. If the LED is using 1% of the power for the same amount of light then its power efficiency is 500%. Hah.

    Incandescents have typical lifespans on the order of 1000 hours. 1000x that is over 100 years. White LEDs will be severely degraded in 10 years and will likely fail completely in much less than 100 years.

  4. Re:Fluorescents are much more efficient on GE Announces Advancement in Incandescent Technology · · Score: 1

    Early CFs, particularly from "Lights of America", had separate bulbs and ballasts. They appear to have fallen out of favor, probably due to consumer inconvenience, the reatiler having to stock twice as many items, and the additional production costs. Also, electronic ballasts are pushed pretty hard, so they don't generally have the long lifetime of a magnetic ballast.

  5. Re:30 lumens/W on GE Announces Advancement in Incandescent Technology · · Score: 1

    A large part of the limit on LED lumen/dollar is the rate that heat can be removed from a small die. As the efficiencies rise, the light that you can get out a single die increases more than proportionately (eff/(1-eff)). They're still expensive, but they're improving at a (historically) very rapid rate.

    Likely they noticed that CFL were cutting into the sales of their regular bulbs and developed the technology so that they can compete.
    GE makes both incandescents and CFs, and their CFs sell for 10 or 20 times as much retail. Even if their CF profit percentage is a bit lower, they make more money on the CFs. The technology improvement should gain market share among incandescents, but likely will cannibalize CF profits.
  7. Re:Curious timing on GE Announces Advancement in Incandescent Technology · · Score: 1

    The inverter efficiency is already included in the watts/lumen rating. The recycling pollution consideration is ameliorated by the long life of the CF. The only valid consideration you raised is power factor.

  8. Re:There are times on GE Announces Advancement in Incandescent Technology · · Score: 1
    Improvement of the incandescent lamp has been ongoing. What do you think "halogen" bulbs are?

    A decade or so ago, GE introduced an incandescent that was very slightly more efficient. If I recall correctly, efficiency was boosted by adding an infrared reflective layer that bounced some IR back to the filament. The improvement was small because the filament is small, and most of the reflection missed the filament. The reflective layer made the bulb a bit more expensive. It has taken a bit of market share, but not much.

    There are several big firms making incandescent lamps, and they've been doing research for a long time. Making improvements aren't that easy, they're up against some hard physical limits like the melting points and evaporation rates and emissivity of tungsten or carbon.

    Some nationalities (and more importantly, some cultures) have a history of making contributions to various aspects of civilization out of proportion to their numbers. It is both interesting to find these correlations and important to find cause-and-effect relations if they exist. Getting annoyed because people point them out, and flaming them, is not a contribution.

  10. Re:Ease of understanding & teaching. on Ramanujian's Deathbed Problem Cracked · · Score: 1
    There is a certain amount of truth to the claim that math is taught badly. Explanations are often not clear, and there is a lot of emphasis on proofs in preference to understanding. This is especially true of pure math as contrasted with applied math. However,

    • some things are just hard to learn and only seem easy in retrospect.
    • People learn differently. The words that bring clarity to me may be muddy to you, and vice versa.
    • The words of someone who knows the subject thoroughly will be very different from the words of a newbie.

  24. Re:eDRAM is quite old on DRAM Almost as Fast as SRAM · · Score: 1
    There is a significant difference between DRAM used in a framebuffer and DRAM used in a cache. In a framebuffer the data is only needed for the time span of one frame, and refresh is not necessary. As long as it's truly used as a framebuffer, nobody cares if it loses a bit occasionally, it's just a blip on the screen. In a cache, errors are unacceptable and lifetime in the cache is somewhat uncontrolled. Accordingly, the data in a DRAM cache has to be refreshed.

    With small devices leakage is a problem, and it's a severe problem for DRAM because it shortens the required refresh interval. If IBM has improved DRAM to make it useful in general-purpose on-chip applications, they've made a big step forward.
