As modern power generation methods are designed to squeeze the most power from the least amount of fuel, engineers are constantly looking at techniques to improve efficiency. One way to achieve this is to scavenge waste energy left over from the production process to capture and convert low-grade heat into usable energy. In pursuit of this goal, engineers at Pennsylvania State University have produced an ammonia-based battery that not only captures and converts waste heat economically and efficiently, but is claimed to do so at a greater capacity than other similar systems.  Read More

There's another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology's (KIT's) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more efficient and inexpensive than the dominant types of batteries in use today.  Read More

Researchers have developed a coating that prevents a battery from conducting electricity w...

It can be a herculean task to get kids to eat their vegetables, but they'll happily chow down on things they aren't supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have found a way to stop kids swallowing button batteries, but they have found a way to make such culinary no-nos safer.  Read More

The Droid Turbo promises two full days on a single charge of its huge battery

The Droid Turbo with its monster specs follows the unveiling of the Moto 360 smartwatch, new Moto X and Moto G and a Motorola-made Nexus 6 that have all been introduced in the past 8 weeks.  Read More

The Type 50 displays the time on the front and instructions for use on the back

To the timepiece layman such as myself, most wristwatches are bland, uninspiring tools that do one job. They do that one job extremely well, of course, but they all – with the exception of innovative watches from companies such as TokyoFlash – meld into one inglorious whole. They do exactly the same thing, and do it in exactly the same way. Which all conspires to make it very easy for the Division Furtive Type 50 to stand out from the crowd.  Read More

Spira allows your smartphone to be used as a wall clock while it's being inductively charg...

Smartphones need charging every day, and those hours when they're plugged into the wall and charging is time when they're doing nothing. Not so with Spira, which turns your smartphone into a work of art while its battery is being replenished.  Read More

Ampy is also pocketable at 3 inches square

Kinetic chargers have been around for a few years, but have typically been big and bulky. Ampy is much smaller and fashionable enough to wear around.  Read More

Researchers at Ohio State University (OSU) have created a dye-sensitized solar cell that stores its own power by "breathing" air to decompose and re-form lithium peroxide. Its creators believe the device, which effectively combines a battery and a solar cell in one, could reduce renewable energy costs by 25 percent.  Read More

By playing around with materials, researchers have reduced the operating temperature of an...

Our ability to store energy has proven a big hurdle in the adoption of renewable energies. But now a team of researchers from MIT has developed a new all-liquid battery system that extends the life of such devices while also costing less to make, a development they say could make wind and solar energy more competitive with traditional sources of power.  Read More

A new nuclear-powered, water-based battery may one day be used as a dependable power suppl...

Researchers working at the University of Missouri (MU) claim to have produced a prototype of a nuclear-powered, water-based battery that is said to be both longer lasting and more efficient than current battery technologies and may eventually be used as a dependable power supply in vehicles, spacecraft, and other applications where longevity, reliability, and efficiency are paramount.  Read More
