The infographic La Gazzetta used to depict this “electromagnetic wheel” doesn’t make much sense on its own. Not only is there no power source depicted, but the embedded wires wouldn’t generate any forward propulsion, even if there was a power source.Microsoft has uncovered a brilliant concept; it is currently working on a laptop battery system that touts to understand the user's behavior to further improve the laptop's battery life.A Microsoft research project recommending the new method of lengthening the battery life of laptops has been put together by researchers Ranveer Chandra, Bodhi Priyantha and Anirudh Badam.

A company blog entry describes how the researchers used a variety of existing batteries that work in tandem with an intelligent software to make the batteries last considerably longer."[The software-defined battery system] combines several different kinds of batteries, all of which are optimized for different tasks, into the same computer," reads the blog post. "Then, it works with the operating system to figure out whether the user is, say, looking at Word documents or editing video footage, and applies the most efficient battery for that task."

Later this week, researchers are slated to present the project dubbed [pdf] "Software Defined Batteries" at the Symposium on Operating Systems Principles.The blog did say that even though it is still a research project, the Microsoft researchers were able to develop functioning prototypes of the battery concept that are anticipated to be used in consumer products down the road.To date, the blog points out that battery charging on a laptop is managed by the hardware, not the operating system, making it inefficient.

The group thinks that although lithium-ion is generally beneficial, it cannot meet everyone's wants and needs.Julia Meinershagen, senior engineer for Microsoft's Surface devices group, is likewise joining the group in this particular exploration.One use-case scenario the blog mentions is that the system may observe that the person plugs in the device every single day at about 2:45 p.m., then gives a lengthy PowerPoint presentation each day at 3 p.m. The blog explains that the computer has to be able to do speedy charge during that time, so the user makes it throughout the afternoon meeting without running out of battery.

In the meantime, the experts believe that a similar principle may also be applied to cars, smartphones and other battery-powered devices.

Panasonic is recalling the rechargeable battery pack sold with its certain models of its CF-S10 ruggedised laptop over concerns it could cause the device to catch on fire.

Australia is one of several nations around the world affected by the recall. The ACCC said machines built between April 2012 and June 2013 are affected.

It advised Toughbook users to immediately turn off their device and check whether it contains a defective battery, evident by the part number CF-VZSU61U.

"There is a risk that the battery pack may overheat and cause smoke or may ignite posing the risk of fire or burn hazard to consumers and to the [computer]," Panasonic said.

The ACCC advised those who suspect they may have a dodgy battery to remove it and only use the machine with the AC adapter, power cord and mains supply power and contact Panasonic for a free replacement.

The devices were sold through Australian Panasonic Toughbook distributor Multi Media Technology.

It appears that the Japanese ministry of industry and trade first alerted Panasonic to the problem, reporting a battery catching on fire in December.

It's enough to make you want to drop everything and race for the nearest power outlet: Your workday isn't even done, and your smartphone or laptop battery is already in the red zone. If you're hoping that techno-progress will dispel that depleted feeling, you may be in for a long wait. Battery life is constrained by limitations in chemistry, and improvements aren't keeping pace with demands from modern gadgets.

We're still dependent on the venerable lithium-ion cell, first commercialized by Sony in 1991; it's light, safe and holds a lot of charge relative to most alternatives, but it isn't getting better fast enough to keep up with our growing electronic demands.

So instead, manufacturers are doing their best to "cheat" their way around lithium-ion's limitations. The CES gadget show in Las Vegas [featured] plenty of workarounds that aim to keep your screen lit longer.

Proceed with caution, though: Manufacturer claims of battery life improvement can fall short of real-world experience.

New Chips

Not that long ago, computer-chip makers competed to make their chips ever faster and more capable, with power consumption a secondary consideration. But the boom in energy hungry smartphones and laptops means that companies like Intel Relevant Products/Services need to put much more emphasis on power efficiency these days.

Intel says its sixth-generation Core chips [pictured above and formerly] known as Skylake, add a little more than an hour to battery life to laptops compared with the previous generation, according to spokesman Scott Massey. The chips utilize a more compact design, hard-wired functions that used to be run via software and fine-tuning how they ramp power use up and down.

Better-Designed Laptops

Laptop manufacturers are smartly sipping power, too.

HP says the Spectre x360 notebook it introduced in March gains up to 72 minutes of battery life, for a total of up to 13 hours, thanks in part to Intel's new chip. Among other tricks, the PC doesn't refresh the screen as often if the image isn't moving. "If we can solve a bunch of small problems, they can add up," HP vice president Mike Nash said.

Similarly, Lenovo's new ThinkPad X1 Yoga tablet turns off its touch screen and keyboard backlight if it senses its owner is walking and has the screen folded back like an open book. Vaio, the computer maker formerly owned by Sony, says its Z Canvas launched in the U.S. in October benefits from shrinking components and efficiently distributing heat to make more room for a bigger battery.

And Dell says it has worked with manufacturers to squeeze more battery capacity into the same space. It says its efforts recently boosted the energy storage of its XPS 13 laptop by 7.7 percent compared to an earlier version of the same model .

Maybe it's your phone that's not keeping up. If so, you might check out new accessories designed to make it easier and faster to charge back up.

Kickstarter-funded Ampy uses your body's kinetic energy to charge up a pager-sized device. Strap it to your arm or a belt and it can recharge a smartphone in real time; an hour of jogging or similar exercise yields about an hour of use. You could also just throw it in your bag and get the same extra hour of gadget life after a week of walking around -- not an awesome trade off, maybe, but possibly better than nothing.

The wireless-charging technology Qi makes it possible to charge a phone without plugging it in. Instead, you lay it down on a special pad and let electromagnetic field coupling do the work. Wireless charging has always been much slower than wired, although Qi's backers say it's speeding up. But wired charging is getting faster, too, at least for phones with the latest hardware -- and with Qi, you still have to line up your device just right on the sometimes fussy pads.

Not the king-of-the-world kind of power. I mean the keep-your-phone- charged power.

Sooner or later, the world is going to run on battery power. Cars are sure headed that way. My guess is that most cars will be electric in 50 years. Solar power relies on batteries to store the energy for later use. And I can't think of too many people who don't plug in at least a cellphone each day to charge up its battery. Rechargeable batteries and external battery packs have really taken advantage of advances in technology. Batteries are smaller and more powerful than ever, and consumers are starting to see some real benefits. I'm not sure anyone realized how big a part rechargeable batteries would play in our daily lives. I've been using and testing various external rechargeable batteries the last few years. I'll admit I'm a battery geek. I've also been carrying jumper cables in my car for 35 years or so. Well, there was a year or two a decade ago when I carried a self-contained jump-starter, but it was almost as big as a car battery, it weighed a ton, and it didn't keep a charge very long. Today we have batteries that will fit in your back pocket that can charge your cellphone or jump-start your car. I've been testing the Weego JS12 Jump Starter ($129.99, myweego.com), which Weego touts as its heavy-duty model. The JS12 is the midsize version of Weego's line of jump-starters. It holds 12,000 milliamp-hours of battery power, and it can jump-start any gas engine up to 6.4 liters and diesel engines up to 3.2 liters. It will start all but the biggest cars and trucks. If you have a greater need, Weego makes a professional model called the JS18 that can start gas engines up to 9.6 liters and diesel engines up to 4.8 liters. The JS12 has a starting current of 200 amps and peak current of 400 amps.
