Cell Mobile Phones

Is it safe to touch exposed wiring from my mobile phone charger?

A small segment of the electrical insulator at one end of my mobile phone charger came off, exposing several thin threads of silver wiring. I'm just wondering if it is safe to touch the exposed wiring? What if the exposed wiring were to come for other


probably not. If you touch them, chances are your finger will become a link between 1 set of wires and another, which could short circuit something. Aside from that, you dont want water / moisture getting in there.

German Bicycle Charges Phones With Pedal Power

Silverback, started in 2004, unveiled a new line of products called the "Starke." The bikes include two models built with the same dynamo technology used to illuminate a bike headlight by harnessing rider energy. Silverback's cycles connect a similar dynamo to a USB port, enabling cyclists to charge a smartphone with every push of the pedals.

As more people use smartphones for battery-draining activities such as watching videos, surfing the Web and playing games, dead batteries and short battery life are increasing annoyances. Solutions such as Silverback's bicycle charger may provide an option for charging devices when users aren't near an electrical outlet.

They also may appeal to environmentally conscious consumers, who might enjoy the ability to power up a device while doing an eco-friendly activity like bicycling and without tapping into the electrical grid.

Other green cell phone charging possibilities have debuted this year, including a transparent screen coating allowing devices to get energy from the sun's rays and a shoe insert that generates electrical energy from people's footsteps, charging cell phones while they walk.
