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

Electron microscope images of the nanometer-sized rods of titanium dioxide that cover the ...

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

The extendable PowerPole has a 5,400 mAh battery built in, allowing for up to eight hours ...

Even with the beefed up battery of GoPro's Hero3+, there's always the possibility of the camera cutting out right as the action heats up. Living out this scenario on the powder-coated ski hills of California led the team at Polar Pro to explore ways of not just extending battery life, but doing so without interruption. The result is the PowerPole, an extendable pole-mount with around five GoPro batteries worth of juice packed inside.  Read More

The tattoo biosensor for monitoring lactate levels that has been converted into a sweat-po...

Last year, researchers at the University of California, San Diego (UCSD) unveiled a sensor imprinted on a temporary tattoo that, when applied to the skin, is able to continuously monitor lactate levels in a person's sweat as they exercise. Now the research team has leveraged the technology to create a biobattery powered by perspiration that could lead to small electronic devices being powered by sweat.  Read More

The Ultrapack Go (left) and Petalite Flux (not to scale) can suck in enough power for a fu...

As our dependence on the smartphone has grown, there's been plenty said about the battery life of said devices. Thankfully, external charging solutions provide a way to keep powered up and now there are two that are laying claim to being the quickest of them all. Both the Unu Ultrapack Go and Petalite Flux are pocket-sized portable batteries promising power enough for a day's smartphone use from a 15 minute charge.  Read More

UC Riverside researchers have developed a lithium-ion battery with superior performance us...

Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand.  Read More
