Ghana man killed by exploding handset?

by Darren Murph, posted Jan 28th 2008 @ 6:02PM


Truth be told, we aren't exactly inclined to believe this here article is entirely accurate, but nevertheless, Modern Ghana is reporting that a resident was recently killed by an exploding cellphone. Notably, this unfortunate accident wasn't due to a faulty battery, or at least that hasn't been blamed just yet. Rather, the young man simply answered his ringing mobile while it was still plugged into the wall, and seconds later, electricity flowed into the cellphone unrestricted and threw the man back. Reportedly, he was pronounced dead on arrival at a local hospital, and we're sincerely hoping that investigators get to the root cause of all this if indeed the tale is true.

Researchers hope to charge up gadgetry with body heat

by Darren Murph, posted Jan 21st 2008 @ 3:35PM


We've heard of firms tinkering with the idea of converting excess heat directly to energy, and apparently, a team of scientists from the US Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have done just that. Oddly enough, the researchers admit that they're still unclear on how their findings actually work, but they've nevertheless discovered how to increase the conversion efficiency of converting waste heat to energy "by a factor of 100." The authors of the report suggest that clothing constructed of material embedded with thermoelectric modules could one day "recharge mobile electronic devices off the heat of one's body," and while we're certainly stoked about the idea, we're already conjuring up awful images in our minds about what this garb will actually look like.

NTT DoCoMo looking towards intrabody communications

by Darren Murph, posted Oct 2nd 2007 @ 7:45AM

We've certainly seen instances of intrabody communications at work, but now NTT DoCoMo is looking to join the fun and hopefully tie cellphones into the equation. Apparently, the firm has "various devices" in development that could utilize an "advanced handset" in certain forms of wearable electronics to give users the ability to unlock doors, make payments and exchange data with a friend with a simple touch. The prototype mobile packs a sensor produced by Kaiser Technology Company, and while the current version can only transmit data at 40-kilobytes per second, a speedier flavor is surely on the horizon.

Unplug your charged phone, save the world

by Chris Ziegler, posted Oct 11th 2006 @ 2:07PM

Who knew that leaving a fully-charged phone plugged in to the wall was such a problem? Nokia's formed a new group -- including rival Motorola, among others -- with the aim of educating folks on ways to use their phones in environmentally conscious ways, a move that seems appropriate for the company recently named greenest among cellphone manufacturers.. Among other initiatives, the group will be pushing to add reminders to phones' displays to unplug them once they've been topped off, a change that Nokia says would power about 60,000 homes a year if just 10 percent of the populace complied. The obvious question is, don't the phones begin discharging once they've been unplugged, thereby requiring deeper and longer charging the next time they're jacked in?
