Woman burnt by charging Apple iPhone 7 as she slept

Tuesday, November 15th, 2016

A western Sydney woman says she has suffered severe burns after falling asleep on her charging iPhone 7.

In a Facebook post, Melanie Tan Pelaez posted a picture of her red, blistered arm and issued a warning to others to keep their phones well away from their beds.

“I recently purchased an Apple iPhone 7 and accidentally fell asleep with my arm on my phone whilst it was charging. I was woken up by sudden pain, pins and needles, numbness and shortness of breath” reads the post.

“I have been an iPhone user since the beginning and have never had an issue or concern, so it’s really scary and disappointing that something like this happened and can happen to someone else”.

Organic power: Nokia charges Lumia 930 with 800 potatoes and apples Video shows how to do it.

Nokia recently showed off an interesting new way to charge a smartphone, though we don’t imagine it’ll be commercializing the method anytime soon.

Part science experiment, part art installation, and (large) part publicity stunt, the Microsoft-owned mobile firm recently teamed up with multimedia artist Caleb Charland to create an organic charging wall comprising 800 potatoes and apples, among other bits and pieces.

While creating an electrical current from edible items has long been the stuff of science class experiments, Charland’s project took the experiment to the extreme, enabling him to charge a Lumia 930 smartphone in the process.

The installation, which was set up on a busy shopping street in London over the weekend, also used copper wire and galvanized nails to help create the necessary electrical current, which was then fed through to the Lumia handset to bring it back to life.

In case you’ve forgotten the details of your primary-school science class, Nokia’s Rhea Fri explains:“Voltaic batteries are composed of two metals that are connected and suspended in an acidic solution. In Caleb’s installation, the metals were copper and zinc (from the galvanized nails).

“They comprised the positive and negative electrodes – the parts of a battery where electrical current enters and leaves. Meanwhile, the acid from the fruit and vegetables (phosphoric from the potatoes and ascorbic from the apples) provided an electrically conductive solution.”

Charland’s hand-built wall-based circuit of apples, potatoes and metal created an electrical current equating to an average of 20mA and 6 volts, Fri said.

Commenting on his installation, the Maine-born artist said, “This work speaks to a common curiosity we all have for how the world works, as well as a global concern for the future of Earth’s energy sources.”

But possibly the best thing about Charland’s battery is that you can eat it once your device reaches full power. Just remember to take the nails out first.

WATER CHARGING LOW SMARTPHONE BATTERY & OTHER GADGETS

Thursday, March 1st, 2012

Everyones  nightmare of the gadget world – a smartphone low on battery.

Now Swedish group myFC says its water-powered charger could be the fix anywhere while battery giant Duracell is championing a push for cars and even stadiums to be built with energy “mats” that would power up phones.

A Californian firm, meanwhile, has launched a phone that it claims can remain charged for up to 15 years, making it the perfect spare in emergencies or disasters.

“The difference between the energy on a phone and the energy we consume is increasing. We need to charge more often but you don’t want to be hooked onto a wall,” said myFC chief executive Bjorn Westerholm.

His firm has therefore come up with a portable fuel cell charger which is slightly larger than a compact camera and which uses just one spoonful of water and a small metallic device called a fuel puck, to fully charge an iPhone.

The PowerTrekk could appeal most to campers, aid workers or the military, said Westerholm, who is exhibiting the charger at the world’s biggest mobile fair in Barcelona.

“It could be sea water, fresh water. You need to carry water with you to survive anyway and the PowerTrekk needs just one spoonful,” he said.

“So you can Facebook, email even when you’re in the outdoors for hours.

“Our value proposition is that you don’t need to go to the grid. You don’t need to wait to charge your phone.”

Competition for solutions to power up phones is fierce.

XPAL Power rolled out a phone with a battery that “lasts 15 years,” said Christian Scheder, chairman of the Californian firm.

The so-called Spareone, which will be commercialised in March, remains charged for up to 15 years if the phone is turned off, and for two months if it is on.

“This is great for emergency, disaster situations,” Scheder said.

Battery giant Duracell meanwhile has its own vision to keep the world charged.

It is championing the PowerMat system, a mat which looks like a small tablet that plugs into the power source and which has sufficient space to charge two phones which are equipped with special protective covers.

But that is just the beginning, Stassi Anastassov, Duracell President, said.

Beyond just targeting consumers with the charging kit, Duracell is at the Mobile World Congress to talk phone manufacturers into designing a slot for a special chip or even build it into the telephone, thereby doing away with the protective covers that are currently required to dock with the mat.

The company further wants to fit the mats in public places, for instance, build them into tables at fast-food chains, thereby allowing anyone with equipped phones to charge up anytime.

It already has a deal with General Motors to fit all vehicles from 2013 with the charging mat. Likewise, it has an agreement to equip New York’s Madison Square Garden, starting with bar tabletops.

“Of course it will take many years, the whole ecosystem will not be up tomorrow,” said Anastassov.

“But our vision is that you will be able to never go out of power, simply by facilitating the whole charging process for you.

“It’s very similar to banking and money. If you want to have cash, you can either have a very big wallet full of money or you have an ATM card,” he said.
