1.     Amazing as it may sound reading.....but here is the way thats gonna please us all to get resolved on issues of mobile charging...so many times it has happened that on our way out either we think the mobile is fully charged or when we talk too much on phone.....or just when one small query will resolve us of a standing problem...the mobile goes offffff......problem : MOBILE BATTERY IS DRAINED ....no more.....please read ahead for brief details on the subject....

2.   The new technique developed by Korean engineers for turning sound into electricity - technology that could allow cell phones to be charged while users chat(...bak bakk).Thus Phones equipt with the technology could generate power from any kind of background noise — meaning the phone could be charging even when you’re not speaking directly into the phone. The need to carry around an outlet charger could be supplanted by time spent listening to music, or perhaps even the sound of the wind roaring past your car window.The technology is made possible by tiny strands of zinc oxide that are sandwiched between two electrodes. As a sound-absorbing pad atop the device vibrates to ambient noise, causing the zinc oxide wires to compress and release. This movement is what generates the electrical current.A prototype has already converted sound of about 100 decibels into about 50 millivolts of electricity. That’s not enough to charge a phone, but it’s an encouraging test, and researchers are optimistic that the technology could soon be developed into something more powerful.
