If you're hoping to attract investors to get yet another iPhone case to an already crowded market, it had better do more than just protect a phone from bumps and scrapes. Snow Lizard Products is giving itself the best possible chance of raising funds for its new AQUA TEK S case for iPhone 4 and 4S with an offering that not only boasts ruggedized protection, but also includes a solar panel, built in battery, and is waterproof up to 20 ft (6 m).  Read More

The Mushroom charger from Bracktron eliminates vampire power when charging mobile devices

The spring-loaded PumPing Tap concept that would eject electrical plugs from an outlet when not actively drawing electricity attracted a fair share of criticism from readers when we looked at it earlier this week. Bracktron has come up with a more practical solution with its line of GreenZero chargers that detect when the device being charged is unplugged or fully charged and automatically shut off to eliminate stand-by – also known as vampire power – consumption.  Read More

Sony's battery breaks down paper to create power (Photo: PhysOrg)

We've heard of gadgets being powered by some pretty crazy stuff, but how about paper? Sony recently showed off a new bio-cell battery that breaks down paper in order to create power. A paper battery sounds a little bit far-fetched, but the technology works, and could potentially change how we power devices in the future. So how does it work? The process starts with an enzyme suspended in water. When paper is dropped in, the enzyme starts to break it down and produce glucose that can then be harvested and used to power a battery. Sony described the break down process as similar to how a termite might eat and break down wood.  Read More

There have been numerous attempts at designing partially transparent gadgets over the years, with the LG GD900 cell phone being a notable example. Fully translucent mobile devices are difficult to produce, however, as they would require a fully see-through battery, which hasn't been available yet. Stanford University researchers now claim to have developed such a device - a see-through, flexible, lithium-ion battery, suitable for powering mobile gadgets like cell phones, tablets or e-readers.  Read More

The New Trent iCruiser IMP1000 external battery pack is claimed to have enough capacity to...

Smartphones, tablets and media players have helped to make our mobile existence so much more tolerable - but they all suffer from varying degrees of the same problem. Battery life is always a nagging concern for regular travelers, leading many to carry some form of external portable power source like the Juice Pack Powerstation we reviewed recently. Even though Mophie's external battery pack proved its worth in our tests, we may just have to trade it in for the New Trent iCruiser IMP1000 - which offers over three times the battery capacity in a similar-sized format and claims compatibility with almost every device in the market.  Read More

Everlasting batteries and self-powering portable electronics have come one step closer to reality, according to the results of a new research by Australian scientists from Royal Melbourne Institute of Technology (RMIT). The group of researchers successfully measured piezoelectric thin film’s capability to turn mechanical pressure into electricity. It may sound like an idea from the realm of science fiction, but the discovery could eventually lead to laptops powered through typing.  Read More

With consumers used to the convenience of refueling their vehicle at the gas station in a few minutes, one of the biggest disadvantages of electric vehicles is the time it takes to recharge their batteries. Now, by separating the energy storage and energy discharging functions of the battery into separate physical structures, researchers at MIT have achieved a breakthrough that could allow EVs to be recharged in the same time it takes to refuel a conventional car. The technology could also provide an inexpensive alternative for energy storage for intermittent, renewable energy sources such as wind and solar.  Read More

Mophie's Juice Pack Powerstation charger for the iPhone, iPod, iPad and all devices that c...

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
