sciencentral.com — As our portable devices get more high-tech, the batteries that power them can seem to lag behind. But Joel Schindall and his team at M.I.T. plan to make long charge times and expensive replacements a thing of the past--by improving on technology from the past.

And there you go again, bad math. In FACT, rechargable batteries AREN'T 1.5 volts, Alkaline are. My point was that's not how capacity is calculated. You just calculated 30,000 mAh. Well, no. That's the capacity at 1.2 volts. If you had 12 1.2volt AA batteries in parallel you'd get 30,000 mAh on paper. If you put them in series to get higher voltage they'd all drain at 2500 mAh. So, you got your math wrong... twice. Even then, NiMH batteries would not hold up to the stress of running a laptop. You'd destroy them very quickly.

@eplawlessif you read the whole article, you'll notice the research is funded by car companies.::flame::

Um, this is already a DUGGED story, nearly two months ago. But I think it's important that we keep bringing this up for updates.

nano tubes aint purchasable at the quicky mart yet. so relax .. this will take a while to become realistic.

"super capacitor. seen it before isn't that much of a step forward and would additional components to smooth out the voltage enough to be feasible."The advance here isn't the capacity of the capacitor, but the increase in energy density. If I'm reading correctly, TFA is talking about getting capacitor energy densities similar to chemical batteries in a similar envelope. That's pretty damned impressive.And the second part of your comment is just plain wrong. The "additional components" you see on the back end of rectification circuits to smooth voltage ARE capacitors. They act like shock absorbers, soaking up spikes and filling in drops. ("audio quality" super caps on car stereo amps are doing this same thing as well) If they do this well in a supporting role, why would you believe they'd do it any less well in a primary role?

M.I.T is awesome, they are capable of anything there. I can't wait to see this technology become more and more readily available in my life-time.

If it lasts forever, what good is it that it recharges fast?

like in f-zero!!! man that would be THE s**t!
