The HyperJuice2 was just launched at IFA

While it may not be likely that one person would need to charge a MacBook and two iPads all at the same time, it’s entirely possible that a group of people (say, a group of people covering an electronics trade show) might need to. If they did, and an AC outlet wasn’t close at hand, a single Sanho HyperJuice2 could apparently do the job. The portable battery pack was just launched at IFA 2012.  Read More

When installing micro-electronic devices in locations that are expensive or hard to reach, or just downright dangerous, you don't want to have to keep returning to swap out a battery cell. City Labs has announced the commercial launch of its NanoTritium betavoltaic power source, a thumb-sized battery that draws on the energy released from its radioactive element to provide continuous nanoWatt power for over 20 years.  Read More

If the idea of your mobile gadget running out of juice leaving you incommunicado (or, heaven forbid, bored) fills you with fear, then a battery pack is the obvious solution. But what if your power needs vary from day to day? Exogear has developed a battery pack that it touts as the world’s first stackable battery pack that is designed to adapt to suit your battery needs, no matter how small or how great.  Read More

Harvard researchers have developed a solid-oxide fuel cell that doubles as a battery

Materials scientists at Harvard have created a fuel cell that not only produces energy but also stores it, opening up new possibilities in hydrogen fuel cell technologies. The solid-oxide fuel cell (SOFC) converts hydrogen into electricity, and could have an impact on small-scale portable energy applications.  Read More

A green, rechargeable battery that is suitable for powering electric vehicles and stationary power storage applications, and that would survive tens of thousands of charge cycles in a useful life of 100 years without loss of capacity. What could be a better innovation for our times? Such a battery has been developed, and recently improved by Stanford researchers. Oh, one other thing. The battery was invented by Thomas Edison in 1901.  Read More

Ceramic tiles coated with battery paint and then heat-sealed powered LEDs spelling out 'RI...

While battery technology has come a long way in recent years, it still places constraints on the size and shape of cellphones and other personal electronic devices. Researchers at Rice University are looking to solve this problem by developing a rechargeable lithium-ion battery that can be painted on virtually any surface ... and early results are promising.  Read More

Design By Many, a challenge-based design community, recently announced the winners of its Electric Vehicle Charging Station competition. First prize was awarded to the HMMY team for its Plug + Play concept. The smart-looking electric vehicle charging station attempts to stimulate awareness of the gap between production and consumption of energy. The design "generates a renewed consciousness of energy use in our modern lives," according to HMMY.  Read More

The AQUA TEK S case offers ruggedized protection and a solar panel for charging its own bu...

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
