What got me about the Borg was "resistance is futile" No, it really isn't! If they didn't have resistance, why were the power lines not burning out? I have seen the inside of a Borg, cold and heartless they are, but LOADS of RESISTORS! The might as well say "Capacitance is Futile" because they will one day run down like an old battery! :)

Sure beats the 2 minutes my laptop battery is currently capable of... :sigh:

I've seen this one before (I think it was mentioned in the CP Insider a while back). When they reach 40 hours capacity for today's laptops in a few years, power consumption will have gone up by a factor of 20 in the laptops of that era. The end result, of course, will be that laptop running life will have been cut in half.

delete this;Nah. Power consumption on the laptop and desktop ends is already mostly capped by the Doesn't Spontaneously Combust requirement.
Otherwise [Microsoft is] toast in the long term no matter how much money they've got. They would be already if the Linux community didn't have it's head so firmly up it's own command line buffer that it looks like taking 15 years to find the desktop. -- Matthew Faithfull

So when this battery explodes, do you get nano-wires in the eye? Everyone's different but 14 hours or so is the most I can see me ever needing (trip from east coast to japan + airport wait) and usually about 1 hr is fine (compute on a bus or something) before I can plug it in. Quick charge times would be better for me, if I could have 4 hr battery life and < 20 min charge time, it would be sweet (probably could heat coffee on the battery do to the power draw too ;)).

You're missing the point. Assuming this lives up to the hype it probably won't be used to make 40hr batteries. Instead the default battery will still probably be ~4 to maybe 8hrs but only 1/10th the size for a smaller, lighter machine. OTOH I might be wrong, I've never really got the 40hr mp3 player logic either.

It's interesting none the less. However, I don't see these advances in technology impacting the way we see the consumer technology space today. What drives these advances? Are the powers that be interested in building a Eutopia? I'd put my money on "With this advancement, we'll be able to continue to charge what we do, or even increase our Margins!" -Business Analyst

Laptops are not terribly useful when being used in a manner consistent with achieving their max rated battery life. You probably do want that 40 hour battery if you want it to more than be a power-consuming doorstop during that long flight :)patbob

Good point. Solid state drives should help a lot too, the peak operating power is much much lower which reduces the peak power load to idle load well.

I'll file this with the UCSD press releases about holographic memory in the late 1980s. Worked great in the lab and was on the verge of commercialization....

HDD are somewhere under 2.5W. Screen backlights are quite a bit more. LED backlights would probably have a bigger impact than SSDs.

You might be thinking voltage, the stats I saw (a little old I admit but probably fairly comparible) http://www.codinghorror.com/blog/archives/000562.html">http://www.codinghorror.com/blog/archives/000562.html computer idle at windows desktop 15W, sleeping hdd power draw 14W, defraging drive usage 18W, CPU idle 15W, CPU working 26W. So hdd is roughly same draw as CPU (and similar to screen as well).

yeah, mine works for about 40 minus 38 hours (or less :sigh: ).

Nope.. just reading the spec on the 2.5" HDD: 0.5 Amps at 5Volts equals 2.5Watts. The old 7200RPM 2.5" HDDs drew 1A @ 5V = 5W, and those suckers get pretty darn hot. And these are max numbers, not nominal, which are typically a lot lower.
Still not convinced, put one of those old 7200 RPM HDD in your laptop and see how much of a difference it makes with the battery duration -- mine only lost about 10-20% of the duration when I did, indicating there's a lot of power being sucked elsewhere. :)
