    carbon footprint

    So yes 90 to 100 watts is challenging.

    Its clear to me that laptops need to be lower power. This is too much power
    for something we leave on ALL the time.

    You want no physical moving parts.
    So instead of disk drives, CD, DVD, etc. you want
    HUGE non-volatile memories. HP is working on memristor
    technology which will hopefully save the day.
    Flash technologies are pretty good ... but still not big enough.

    Someone should re-think the display. Instead of producing the
    light ... is there a way to utilize "ambient light" already in the room?
    This is more of an old-school LCD approach.
    Certainly going lower-res is less power ... but the trend
    is higher and higher res. Everyone wants 1080p or better.
    Perhaps there is a low-power way to stimulate the EYE
    directly ... to exploit the eye's natural abilities.
    Also, it seems to me that the spectrum that they eye can
    handle is LARGER than visible light ... in some people ...
    and peripheral vision is another CHANNEL of input
    not yet exploited by man-machine interfacing.
    It might be useful to search for materials that can
    charge up via ambient light ... and re-glow with color changes
    due to electro-static charges.
    Also, wouldn't it be WAY-COOL if you could have a computer
    display that could produce UV light to make your posters glow?

    COLD equals less power...
    If you live in a cold climate, you save power in computing.
    No need to have a FAN to cool. Your good.
    If in a warm climate, you need smarter ways to cool.
    There are fuzzy logic algorithms that can drive cooling fans
    in a more efficient way to cool circuit boards.
    Boards should be cooled with smaller, lower power fans ... many of them
    ... each independently controlled.

    Wired communication vs wireless
    -- Wireless comm. although all the rage is more power.
    It takes power to BLAST your bits over the air waves.
    Be wired instead ... and have a low power router instead.
    Your power budget must include the router too.
    Computers are boring w/o communications to the web.
    If you must be wireless ... consume less
    streamed data ... and opt for receiving FULL files
    ... and then consuming the content of files.
    Streaming is more inefficient and burns power at a longer
    time period. BURSTs of highly compressed data is
    a better use of time and power.

    Computers need to be designed with gated clocks and
    lower power features. When peripherals aren't used, they should
    power off --- w/o hurting the buss. Clocks can be
    adjusted to run slower when computers are not busy ...
    and speed up when computers start to get loaded.

    Low power computing ... I hope .. will start to appear
    in this decade.

    I would like a laptap that is more more like 10 watts ...
    which would be very easy to run on a pretty small solar panel.
    Or, if I'm going to peddle a bike for 1 hour to get 200 watts,
    I want to be rewarded with 20 hours of computer time.
