Nano Battery !!

Researchers at the Fraunhofer Researach Institution for Electronic Nano Systems ENAS have developed a battery the weighs less then 1 gram and is less than 1 millimeter thick. The battery, which can be fprinted in a process similar to silk-screening shirts, could power bank cards or other slim application carriers. " The battery is environment-friendly as it contains no mercury. Its voltage of 15.V lies within the normal range. By placing several batteries in a row, voltages of 3V,4.5V and 6V can also be achieved.

All in one mobile phone charger.

After months of negotiations with hte European Commission, major producers of mobile phones have finally agreed to develop a standard for phone charging based on the Micro USB interface. The companies that signed the MoU include Apple, LG, Motorala, NEC , Nokia, Qualcomm, Research in Motion, Samsung, Sony Ericsson and Texax Instruments.
With this agreement, consumerswill be able to charge mobile phones anywhere from the new common charger. This also means considerably less electronic waste, because people will no longer have to throw away chargers when buying new phones. The large majority of phones will charge within two hours with the new common chargers, says the EU. Only in combination of a large battery with a small charger, the phone will charge within six hours.
