Eneloop batteries get C and D-sized, still not bigger than yo mama

First it was radios, now lights. The Freeplay Foundation has undertaken a new project -- dubbed LifeLight -- which aims to provide just a few hours of lighting each night to the 500 million or so sub-Saharan Africans without appropriate access to electricity. The idea is to place a wind-up (or foot-pump driven we presume) base station into the home which charges a collection of detachable lights. Similar to the technology behind the 150,000 wind-up Lifeline radios (pictured) they've already distributed. Freeplay hopes to replace expensive and unhealthy kerosene or battery powered lamps currently in use with their low-cost, environmentally safe alternative -- local women will be trained to sell and repair the devices. Prototypes are being readied with tests to begin in Kenya in the "next few months."
It's been a tick since we've heard details on an emerging battery technology that promises to trounce even the best products currently available, but researchers at the Department of Energy's Argonne National Laboratory have reportedly developed yet another approach to boosting Li-ion capacity and stability. The technology is "based on a new material for the positive electrode made of a unique nano-crystalline, layered-composite structure," which allows an active components to provide for charge storage while residing in an inactive components which assists in keeping the risk of explosion low. Current claims are putting the capacity right around "double that of conventional Li-ion cells," and it could be used in a variety of wares from "mobiles, laptops, pacemakers and defibrillators, or even hybrid / electric vehicles." Unfortunately, there was no timetable as to when scientists expected said technology to actually be available commercially, so until then, we'll consider this yet another promise on pause.
While the IEEE is "hard at work" revising the laptop battery standard so these explosive cells permanently become a thing of the past, Panasonic has developed a new rechargeable battery pack with increased capacity and energy density, hopefully working on previous heat issues as well. The prototype, which is being shown here at CES, reportedly boasts a "20- to 40-percent" increase in capacity by using "an alloy material for the negative electrode instead of a commonly used carbon material" such as graphite carbon. Additionally, energy density per volume is increased to 740 Wh/L, which is 40-percent higher than that of the company's existing product. Notably, Panasonic claims that this newfangled Li-ion pack will tout a "heat-resistant layer made of insulating metal oxide," which purportedly "ensures improved safety while maintaining a current capacity as high as 3.6 Ah." As expected, there was no word on if (or when) this prototype would actually hit production, but the firm did state that it would like to commercialize it "within a few years" if everything progressed nicely.
If you were lucky enough to snag a new console (or better yet, unwrap a free one) this holiday season, you're probably winging it with just one or two controllers until you can start hacking away at that towering December credit card bill and pick up a few extras. If so, Nyko's got its aim on you, hoping to snag those would-be first-party controller sales away from Sony and Microsoft and get a big fat Zero between the cusp of your hands. The 2.4GHz wireless controller already available on the PS2 (pictured) will soon be available on the Xbox 360 and PS3 consoles, giving users another option if you aren't too fond of the ones already out there. These Zeroes will reportedly feature "heat-dissipating aluminum panels, backlit buttons, and a unique ergonomic design," but unfortunately, won't save you any cash in the process, as each of these (along with an apparently less important PC flavor) will be available for $49.99 when they land shortly after CES.
Having one surgery is plenty, and having some foreign object implanted in your being is really pushing things, but knowing you're going to be under the knife every ten years or so to get a new battery is just absurd. Thankfully, a group of researchers in the UK feel the same way, and are well on their way to developing a battery-free pacemaker. Reportedly, the device would use a microgenerator producing electricity every time the patient moves, effectively eliminating the need for an internal battery. The cost of the £1 million ($1.96 million) project is being shared by the Department of Trade and Industry and private companies, one being Zarlink Semiconductor who has a large role in the device's development. Other teams around the globe are also seeking to create such a unit, with ideas spanning from tiny generators that receive power from heat right onto "biological pacemakers" that would correct heart problems without the need for a mechanical device. While there's no estimate as to when these gizmos will even hit the testing and approval phase, it seems that things are moving along quite well, but we have to stop and wonder how well a pacemaker powered by motion will function when you, well, cease moving.
