    After 18 months or so of more testing and patent applications, this is expected to be on the market in 3-5 years and will revolutionize the entire electronics industry, including electric cars needing recharges.

    Story here.

    And it's all at the U. of I., too. :)

    If the part about electric cars holds true, that is a serious game changer!

    The whole thing is. This is in the "Wow!" category.

    Who says it has to be any different? Remember, the only thing that changed here was the molecular composition of the battery's innards, allowing electricity to flow at its normal speed.

    Portland,...
    The battery can accept a charge at a much faster rate. Therefore, we need to transfer that power (via a cable) much faster. If we stay at regular household voltage, we need much bigger cable to handle all that current. Otherwise, we need to step up the voltage to something higher and that could require a higher rating of insulation on the cable, not to mention changes at the transformer.

    However, we don't know this for sure because of this brand new invention. Who's to say that they won't also invent a connection that doesn't need to be what you state it ought to be?

    Could be a game changer if the oil companies dont buy up the patents and burn them with crude.

    I don't know what this innovation is... but I know what it should be.

    The real problem with charging traditional batteries isn't that they "can't" send more voltage/current to charge faster... but that in doing so it burns up the battery before it would charge.

    Think of cooking a steak. IF you have a 1-inch filet (thickness) and you want it well-done throughout... You can't turn up the heat to cook it faster because the outside will burn to a crisp before the inside cooks sufficiently... so what you have to do is cook it slower.

    Staying with steaks... you can butterfly-cut that same filet, and have a 1/2-inch thick steak that will cook faster... because you've exposed more surface area.

    Now back to batteries... most batteries are actually multi-cell batteries anyway... linked together inside the casing to appear as if a single battery... but we have only 1 single point to charge the whole shebang.

    Now... imagine you have a battery that is composed of 10 smaller cells... and you run additional wiring inside that battery to a surface point so that you can actually charge each of those 10 cells in parallel. You should be able to charge that "battery" 10 times as fast as if you charged from start-to-end using traditional means... and it wouldn't use any more power to do so. In fact, because some electrical transfer is lost to heat... the fact that you charge it quicker means less heat and less lost energy... so you probably would use less electricity.

    Taken to extremes... you could have micro-cells... and micro cables to charge in parallel... and each micro-cell would take minimal power to charge and would charge almost instantly with just a fraction of the available volt/amps from a 110 AC socket... and all of them added together would be the power output desired for the particular device.

    IF I had the money and the lab and people to work on it... I actually think this should be fairly simple to get a prototype working. Making it cheap to produce and perfecting it + having adapters so people could replace their current batteries with this new style would be a bit more difficult... but actually, I'm surprised it hasn't been done sooner.

    The biggest issue here is that there will have to be more effort into quality checking devices as well. A power drain that normally would only draw 1% per hour could deplete a battery in minutes if the technology didn't hold back the amount of power that could be drawn from at once.

    Just read the article. Nano technology. Quantum mechanics finally being used. Interesting. This is stuff that Einstein couldn't understand and didn't want to deal with. Theoretically, using Quantum Theory, you can exceed the speed of light. Don't think anyone's done it yet.

    That's exactly what I said... "it wouldn't use any more power to do so"...

    I only allowed for the possibility that there might be a potential for greater efficiency due to the lower charge time means less energy lost due to heat.

    Technically speaking... unlike filling buckets with water... we are charging batteries via an essentially lossy process... so it takes more than 100 watts to charge a battery capable of storing 100 watts because some of the charging power is lost due to the inefficiency of the exchange.

    If we can charge faster, then we might actually waste less energy....

    So you're right in that it will always take at least 100 watts to charge that particularly battery pack... but maybe instead of 150 watts it could only take 130 if we lose less energy due to the faster process.

    There was a recent Nova 'Making Stuff Cleaner' that you should catch. It had a half dozen or more developments that if one or two come to production it will be a game changer in the car / fuel / battery / fuel cell systems.

    This nanotube matrix should definitely improve battery technology.

    Battery improvement in vehicular use will not be of much benefit without the infrastructure to support it. About half of our electricity is produced by burning coal which currently produces more emissions than the fuel burned for transportation.

    Sounds like the story at hand, then, just might be that one or two that come to production.
