"Smart" lithium-ion battery would warn users if it is going to ignite

By - October 14, 2014 2 Pictures
There have been numerous cases of lithium-ion batteries catching fire in everything from mobile phones and laptops to cars and airplanes. While the odds of this occurring are low, the fact that hundreds of millions of lithium-ion batteries are produced and sold every year means the risk is still very real. Researchers at Stanford University have now developed a "smart" lithium-ion battery that would provide users with a warning if it is overheating and likely to burst into flames. Read More

Pelty Bluetooth speaker powered by ... fire

By - June 30, 2014 5 Pictures
Chatting happily over a sumptuous dinner on the balcony, you bask in the warm summer breeze that blows gently past, sipping your wine and enjoying the company of a few special friends. The day is nearing dusk, so you reach over to light a candle and, as you do, soft music magically wafts from the candle holder, adding to the elegant mood. Your friends are impressed, and the evening is a hit. But where did that music come from? It came from Pelty, a Bluetooth-enabled, candle-powered speaker with an inbuilt thermoelectric converter that lets you play music streamed from your phone without the need for batteries or cables.

Sigelock's Spartan system re-invents the 100-year-old fire hydrant

By - June 4, 2014 11 Pictures
The traditional fire hydrant, that innocuous little cast metal tube with a hat, is one of those everyday objects that is so commonplace most people tend to overlook them. For over 100 years this life saving device has changed little in terms of design or functionality, but now an ex-fire fighter hopes to change all that with his next generation Spartan fire hydrant.

Fighting fire with explosives

Building on a technique commonly used to extinguish oil well fires, Dr Graham Doig from the University of New South Wales' School of Mechanical and Manufacturing Engineering is examining whether explosives could be used to fight out-of-control forest and bushfires by blasting the flames out of treetops, slowing the fire and making it easier to fight on the ground.

New electrolyte could mean an end to spontaneously combusting lithium batteries

By - February 11, 2014 1 Picture
Last year, lithium-ion battery fires became a hot topic, pardon the inescapable pun, with both a Tesla automobile and the Boeing 787 Dreamliner succumbing to fires. In cross-disciplinary research at the University of North Carolina (UNC), a compound being studied to prevent marine life from sticking to ships may also be the solvent (and the solution) to keep lithium ion batteries from catching alight when they overheat.

Lithium batteries could soon be safer, thanks to a material inspired by gum

By - February 5, 2014 1 Picture
Although high-capacity lithium batteries make many of today's mobile electronics possible, they do have one flaw – they occasionally catch fire. This can happen when they overheat, and their liquid acid electrolyte ignites and leaks out. Now, however, scientists at Washington State University have created a gummy electrolyte material that could make such fires a thing of the past. Read More

Digital positioning shoes keep track of firefighters

By - January 15, 2014 1 Picture
Disorientation inside smoke-filled and unfamiliar buildings can be a major obstacle for firefighters – and it's not as if they don't have enough to worry about already. Researchers at KTH Royal Institute of Technology in Stockholm have addressed this problem by developing fancy footwear that allows firefighters to be tracked in places where GPS fails, including up to 25 m below ground.

Spruce Stove burns one long log, a bit at a time

By - November 20, 2013 8 Pictures
I speak from experience when I say that it's actually fun to go into the woods, saw up fallen trees, then bring the wood home to burn over the winter. What isn't so much fun is subsequently sawing the logs into stove-length pieces. With the Spruce Stove, however, you don't have to – you just continuously feed one long log in as it burns, sort of like feeding a pencil into a pencil sharpener. Read More

SafeFlame torch turns water into fire

By - November 5, 2013 3 Pictures
The pressurized acetylene and propane gas used in brazing and related tasks is highly flammable, and thus very dangerous. You know what isn't flammable, though? Water. Bearing that in mind, the European Union-funded SafeFlame consortium has developed a torch system that generates a flame using nothing but H2O and electricity. Read More
