New type batteries for the future?

    I thought maybe some of you battery fans might be interested in the
    article below which was on CityTV Toronto today on a local news website.

    Canon is working on a new way to power high-tech devices that could
    spell the end of traditional batteries.

    The Japanese company has developed small fuel cells for use in some of
    its digital cameras and computer printers - it hopes to have the
    technology ready for the market in three years.

    Toshiba, NEC and Hitachi are also working on similar fuel cell batteries
    for the next wave of consumer electronics - which could be used in
    mobile devices, phones, and laptop computers.

    Fuel-cell technology combines hydrogen and oxygen to generate
    electricity, and is seen as a likely replacement for today's models of
    lithium-ion batteries.

    Canon is one of the globe's top manufacturers of photocopiers and
    cameras - it's looking for new areas of growth as the digital camera
    market begins to cool down.

    While most current fuel cell development employs devices that take
    hydrogen from methanol, Canon wants to be able to supply hydrogen
    directly from a refillable cartridge.

    The company argues the system would be more earth-friendly, since
    deriving hydrogen from methanol gives off a byproduct of carbon dioxide.
    Hydrogen-only fuel cells don't.

    There are three prototypes so far, of different sizes - the largest
    would likely be used in a printer, the next would fit a digital camera,
    and the smallest - measuring only 3 cm by 4 cm - is meant for smaller
    mobile devices.

    Another potential benefit to fuel cell batteries is that they're
    expected to last longer than their lithium-ion counterparts.

    Still, it could be awhile before they make it to market - the prototypes
    have to be tested, and Canon still has to decide how to sell it,
    although it'll probably entail refilling the cartridges at company
    outlets. "

    Wonder what they plan to do with the water generated by hydrogen fuel
    cells. I really don't think I want my camera or cell phone to make a
    puddle on my foot. Grin.

    Now there's an improvement worth talking about. Not many other
    battery types leak only water. And if you are puddle phobic, don't
    ever hold a toddler. :)

    Considering how flammable hydrogen is, I'm not sure I'd want it right by my
    ear, either...

    Sounds like an inconvenience if you have to take it someplace to get
    recharged. What do you do if you need to recharge in the middle of nowhere?
    I'd hope they last a while in that case. How much longer though? 20%, 50%,
    100%??
    Rather my lithium ion battery which I can charge in the car if I need to.

    Saw an ad for an LED flashlight that provides lots of light after a 30
    second shake. Probably a strong magnet, big coil, diode, charge a big
    capacitor type thing. Also we now have 30 second wind-up radios that play
    for half an hour. Will we next see a wind-up or shake me digital camera?
    Perhaps ordinary batteries are doomed for extinction.

    It's my understanding that the water is produced as a vapor, and it's
    not very dense (low humidity factor?), so the dew point is very low.

    The refillable battery would be removable, so a spare could be
    carried.
    A question that might be more important: would we be able to carry
    this bomb on an aircraft?

    There's oxygen in the air.
    This won't work?

    I wonder about using hydrogen. There are other feasible fuels.
    The bit about giving off carbon dioxide is a red herring. Making
    hydrogen gives off *lots* of carbon dioxide. You don't mine
    hydrogen...

    Something like propane in a container like a cigarette lighter
    would seem to be in the right ball park. Available, cheap, and
    easy to carry spares.

    I require oxygen and have no problems getting any. Where I
    can get oxygen my fuel cell can get oxygen...

    PS: As for old batteries, I'd love to find a proper one
    for my Minolta SRT101...

    According to the Times this morning Sony are working on small fuel cells
    to used instead of batteries.

    The electrolysis process doesn't give off carbon dioxide.

    Not likely, but you may need to actually use one of those radios
    or lights to understand why. Shaking and cranking every half hour
    gets old very fast when you realize that LED lights and radios are
    available that operate hundreds of hours from a single set of AA
    batteries. Not many of these windup or crankable devices will ever
    be used when batteries are unable to be purchased, but that's how
    they're usually promoted. The original Freeplay radio was, IIRC,
    designed for use in remote areas of Africa where batteries were
    either very expensive or not readily available. Makes more sense
    there. Here, such radios appeal mostly to gadget collectors and
    survivalists waiting (and possibly hoping) for Armageddon.

  17. last pass with the D2x gave 1039 shots,
    with postview on, and the battery showed 39% remaining.

    thats about 5 times better than the S2 pro.

    No, but you have to get that electricity somewhere.

    I didn't see anything that said this new battery would be sealed.
    It couldn't be sealed, anyway. You have to vent the water vapor
    somewhere.
    We don't know yet. The development isn't finished.

    I have some flashlights that are sealed - and some that aren't. All
    are current generation.
