Intel has been spending gazillions building chips that suck less and less juice, then crowing that its chips last longer than AMD's, according to something called the MobileMark 2007 benchmark. AMD claims the MobileMark 2007 benchmark doesn't reflect how actual humans use actual computers and wants the industry to adopt new ways to measure battery technology (which sucks, by the way, if I haven't made that clear).
Rob Enderle, a longtime industry analyst who doesn't mince words, puts it thusly:
Everyone in the industry knows this benchmark is wildly optimistic and that the actual battery life you'll get is often less than half what MobileMark suggests. This is because MobileMark measures battery life much like you might measure gas mileage if you started the car, put it in neutral and coasted down a long hill.
Or, less colorfully but more literally, the New York Times' Ashlee Vance reports:
Patrick Moorhead, a vice president for marketing at A.M.D., said the parameters for this test include having the screen at just 20 percent brightness, Wi-Fi turned off and no music, video, games or Web pages running. More or less, the test turns a computer into a dimly lit clock, then sees how long it can run.
And thus we come to the lawsuit, which is really just another front in the long-running war between Intel and AMD (and, if successful, yet another attorney economic stimulus package). That laptop battery claims are lampoonish is a given; how much consumers have been harmed by that may be up a jury to decide, if the class action is ultimately approved.
If the suit resulted in batteries that actually lasted as long as vendors claimed they did, I'd jump in with both feet. Somehow I doubt that's gonna happen. Meanwhile, PC vendors continue to generate generously optimistic claims about how long their machines will last.
Right now, for example, I've got a Acer Timeline AS3810T charging up on my desk. It's a sweet-looking, dare I say MacBook Air-like, Intel-based ultrathin that claims to deliver 8 to 9 hours of battery life, thanks to -- you guessed it -- the MobileMark 2007 benchmark.
If I can lug this sucker around for 8 hours doing what I normally do before I have to start hunting for an AC outlet, I will eat my hat, washed down with a tall frosty beer. Heck, give me 6 hours and I'd be happy.
I'll let you know how that goes and, possibly, how my hat tastes.

Ensuring acceptable application delivery will become even more difficult over the next few years. As a result, IT organizations need to ensure that the approach that they take to resolving the current application delivery challenges can scale to support the emerging challenges. This handbook elaborates on the key tasks associated with planning, optimization, management and control and provides decision criteria to help IT organizations choose appropriate solutions.

A common misconception is that mid-range storage requirements are dramatically different than that of a larger enterprise. Mid-range storage users may require less capacity, but they have similar functionality and management requirements. This ESG paper examines mid-range storage needs and reviews a new solution that adjusts size while retaining value, performance and functionality.

Stanford (search: stanford silicon nanwire battery) claims "Nanowire battery can hold 10 times the charge of existing lithium-ion battery" (on Stanford's site)
Additionally, if these geniuses could combine their technologies, there's yet another claim (search: charge battery in 10 seconds).
"Ultra-High-Power Lithium-Ion Batteries" (on MIT's site)
Here is the nuisance: these articles have been around for at least 2 years. WHERE ARE MY BATTERIES!? I have an electric car. This would be AWESOME! Even if they were half-right, I could go a thousand miles on a single charge.
Moreover, there's a battery maker called AltairNano - that supposedly has a battery in production. SELL TO CONSUMERS!
Please!
The harddrive manufacturers have done amazing things with harddrives... Where have the battery manufacturers been - for the last 15 years? Electric Wheelchairs! Cordless shavers! Cellphones (my cell phone's battery barely lasts 36 hours). Wireless keyboards and mice! Who knows? little bitty electric coolers or heaters for drinks (much like the rubber boot folks put around their soda-bottles today)... There are literally millions of uses, some of which hasn't even been considered because the tech isn't available.
Who told you that Strontium-90 completely decays? And that it decays into non-toxic elements? I have a College Degree in Chemistry, and I can tell you for certain that neither statement is true! And as for capturing "fast-electrons" -- this is physically impossible and will remain so.
It seems that every time the price of gas goes up, we get rehashes of the "60 mpg carburetor". And now that battery life is an issue, we get the rehash of the old "radioactive battery" nonsense. Read Snopes.com a few times and you will find dozens of these fake claims exposed.
Closer to reality than OregonJim, but still not practical. Give it five years, and maybe the outboard fuel cells will be developed. But airlines will still regard these devices and their fuel as bombs, so it's still not a practical solution.

The Seattle Airport's beautiful, new (2 or 3 years old) departure lounge has giant plate glass windows, floor to ceiling. It has large airy spaces, little intimate tables spread around the area, nice small laptop sized work/eat tables all along the 150 foot long window overlooking the runway.
It's got Starbucks, Ivars and other big hitters so far as food and beverages.
It's an awesome space to sit.
It has one outlet. ONE OUTLET. Hidden back by the service entrance.
ONE OUTLET. Did I make that clear?
Good thing I have a five hour battery, eh?
