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
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

MIT's improved all-liquid battery could make renewable energy more competitive

By - September 24, 2014 2 Pictures
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.
