A firm that provides the technology of charging electrical and electronic products wirelessly has predicted that mobile phones and laptops would do away with power cords within a year.

WiTricity CEO Eric Giler said wireless transfer of electricity will soon be commercially available as the company is close to fine-tuning its capability to convert electricity into a magnetic field that could then be sent through the air on a certain frequency. The magnetic field is transferred to witricity-enabled gadgets through WiTricity's technology called magnetically coupled resonance.

General Motors announced Tuesday that its Chevrolet Volt electric car has been given an EPA rating of more than 230 miles per gallon - city and a average over 100 miles per gallon for city and highway combined.

The mileage tests were done using new fuel economy standards devised by the EPA for Plug-in Hybrid Electric Vehicles (PHEVs). Based on the new guidelines, the Volt would become the first mass produced vehicle to sport a gas mileage rating in the triple digits.

An international team of scientists have created a new state of matter when they made aluminum transparent or invisible by beaming a very powerful x-ray laser to it.

The new state of matter existed only for 40 femtoseconds or a fraction of a nanosecond after being blasted by a FLASH laser in Hamburg, Germany. With the energy equivalent to the amount of electricity that powers a city, the pulse of soft x-ray light from the laser knocked down an electron in each ion of an aluminum foil making it transparent.

Tiremaker Bridgestone Corp is branching out to make electronic paper (e-paper) for electronic book readers with plans to announce full details soon.

The company reportedly says that its electronic paper can replace regular paper.

The ability to charge your cell phone literally from the thin air may someday be possible if experiments at the Nokia Research Center here come to reality.

Researchers are studying how to convert ambient electromagnetic radiation, such as that emitted from wi-fi devices, cell phone towers and TV masts, into electrical signals that could recharge cell phones.
