Cleaning up wastewater from oil and gas operations using a microbe-powered battery

By - March 2, 2015 1 Picture
A treatment process developed by engineers at the University of Colorado Boulder promises a simpler and more economical way to clean up the wastewater produced by oil and gas operations that is heavily salinated and full of organic contaminants. The technique, which involves the use of a microbe-powered battery, also produces rather than consumes energy. Read More

Energizer's "EcoAdvanced" batteries are partially made from recycled cells

By - February 4, 2015 1 Picture
Energizer has announced a new line of high-performance AA and AAA alkaline batteries that are in part made by recycling old cells, in what's claimed to be an industry first. Although currently only four percent of the battery comes from recovered materials, the plan for the company is to grow that percentage tenfold over the next 10 years and eventually use recycled materials in all its future cells.

Peri Duo: iPhone battery and speaker case rolled into one

By - December 23, 2014 3 Pictures
A new iPhone add-on devised by California-based company Peri aims to give iPhone users a double whammy: more battery power and sound volume, all for less cash. Called Peri Duo, it comes in the form of a case that integrates a speaker system and a 2,500-mAh battery. When detached from the phone, it becomes a speaker whose aural power is strong enough to disturb the neighbors. Read More

Ammonia-based battery system to convert low-grade waste heat into electricity

By - December 7, 2014 2 Pictures
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.

New electrolyte to enable cheaper, less toxic magnesium-sulfur-based batteries

By - November 30, 2014 1 Picture
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.

Coating makes swallowing batteries safer for curious kids

By - November 5, 2014 2 Pictures
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 Division Furtive Type 50 shines light on tired timepieces

By - October 21, 2014 8 Pictures
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
