For the rest of 2011, I'm visiting a new country every week or two. I'm not the biggest fan of getting lost, asking for directions, or getting ripped off by taxi drivers, so keeping my iPhone's battery charged is high on my list of priorities. I came across Mophie's Juice Pack Powerstation while I was doing my pre-travel gadget shopping, and was surprised at how small, light and cheap the unit was. So how does it stack up?  Read More

The mixing entropy battery could be used to build power plants at estuaries where fresh wa...

Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants where fresh-water rivers flow into the ocean. The new "mixing entropy" battery alternately immerses its electrodes in river water and sea water to produce the electrical power.  Read More

A new discovery by U-M researchers could see energy from the sun harnessed without solar c...

It has long been thought that, even though light has electric and magnetic components, the effects of the magnetic field are so weak that they could effectively be ignored. Now researchers at the University of Michigan (U-M) have discovered that under the right conditions, a light field can generate magnetic effects that are 100 million times stronger than previously expected. The researchers say the discovery paves the way for the creation of an "optical battery" that could harness power from the sun without the use of solar cells.  Read More

While those of us living in First World countries may take an easily-accessible source of continuously-flowing electricity for granted, such is not the case in developing nations. Many communities have little or no electrical infrastructure, and experience frequent power outages. While people wishing to read a book in the evening could perhaps use a simple lighting device like the Solar Pebble, the matter becomes quite a bit more serious should the lights go out at a hospital, in the middle of an operation. Many hospitals have turned to using kerosene lanterns, but Australian industrial designer Michael O'Brien has created what he believes is a better alternative – a low-cost battery-powered LED surgical lamp.  Read More

GoPro has just released its Battery BacPac, which allows a second lithium-ion battery to b...

Just last month, GoPro introduced the long-awaited LCD screen module for its viewfinder-less HERO HD actioncam. At the time, the company stated that the module was the first in a series of BacPac accessories, designed to extend the capabilities of the 1080p high-def camera. Now, the next of those accessories has been released, in the form of the Battery BacPac. It allows an included 1100mAh lithium-ion battery to be mounted onto the back of the camera (which already has its own identical battery), potentially doubling its run time.  Read More

The Icon charging unit for iPhone

We've covered a number of iPhone portable chargers in the past, ranging from the well-known Mophie Juice Pack to the environmentally friendly iCharge Dx. There are countless solutions that will ensure that your green battery indicator icon stays fully green, the difference with this iPhone charger is that it's been designed to resemble that very same indicator graphic. Appropriately, it's called the Icon.  Read More

A molecule of fulvalene diruthenium, which changes its configuration when it absorbs heat,...

In figuring out how a molecule called fulvalene diruthenium works to store and release heat, researchers at MIT may have paved the way for a rechargeable battery that stores heat instead of electricity. Although the molecule was discovered in 1996, ruthenium’s rarity and cost has ruled out it’s widespread use but the researchers say understanding the fundamental mechanism of how the molecule works should make it possible to find similar chemicals based on more abundant, less expensive materials.  Read More

DARPA's proposed batteries would be smaller than these grains of salt (Photo: Mark Schellh...

As development of micro- and nano-scale devices continues to advance, so does the need for an equally-tiny method of powering them. There’s not much point in developing a surveillance micro air vehicle the size of a housefly, for instance, if it requires a watch battery in order to fly. That’s why DARPA is funding a project to create really tiny batteries. Just how tiny are we talking, here? Well, they’re aiming for something smaller than a grain of salt.  Read More

There’s no arguing that batteries are an essential element of today’s electronics landscape. Without them our mobile devices would be a lot less mobile and we might still be crank starting our cars. The explosion in mobile electronic devices enabled by batteries and miniaturization has a major downside in the form of discarded batteries, the majority of which contain toxic heavy metals. Chemists have now discovered a new way to pass electrons back and forth between two molecules that could see the development of organic batteries that are lightweight and work without the need for toxic heavy metals.  Read More

The Sanho Corporation has announced a new iPad-specific addition to its HyperMac battery solutions. Apple's tablet computer can be placed into one of two angled slots on top of the HyperMac Stand which create the perfect angle for movie viewing or for eBook reading. The stand also serves to extend iPad enjoyment by adding another 16 hours to its battery life.  Read More
