Now charge your phone using WiFi!

No need of costly Electricity

WiFi is famous for sucking the life out of mobile phones, it is a well known fact that the greatest cell phone battery would whimper and die after prolonged use of Wifi, however all that may change when WiFi energy takes over.

Scientists from a little company called RCA have invented a handy gadget that allows a mobile phone to harvest the WiFi energy and convert it into electricity! As a result mobile phones would be charged for free, without the need to plug in the pesky chargers. The gadget was unveiled at the CES this year, and in our opinion it beats innovations like 3D TVs and tiny ebook readers, let alone motion controllers.

The device is named the 'Airnergy Charger', and while the technology isn't brand new, it is the first time a commercial product has been developed using it. Tests results showed that the Airenergy was powerful enough to charge a Blackberry from 30 percent battery to full battery in 90 minutes, all the while using free energy! The Airenergy comes with a little battery and the gadget itself is small enough to be carried around in a pocket. According to the RCA, the Airenergy would be available in stores by May, and will cost around $40. That is an amazing price for a gadget that revolutionises technology and energy saving. And you don't need to worry about charging the battery of the charger, the 'Airenergy' charges itself when it is anywhere near a WiFi source. If you have a home wireless network, you could just leave it anywhere in your house overnight and it would be fully charged by morning.

Below is a video which demonstrates the gadget. Check it out, its worth the buffer.

Earlier we reported that Taiwanese scientists at the Industrial Technology Research Institute successfully created a hydrogen-powered charger for mobile phones. The device will be able to recharge a mobile phone battery in less than two hours. The scientists expect the device to go mainstream by 2012 and by 2015 almost all of the world's mobile users will have hydrogen-based mobile phone chargers instead of the electric ones that are used at present. Also, Hydrogen in theory will produce no hazard to the environment.

iPhone 4G from iphone

Some overzealous folks created a visual guide to the Apple Tablet rumors a few days ago, now up pops a similar idea from French website Nowhere Else for the next generation iPhone.

As per the image (and the rumours) the creatively named iPhone 4G has a saucy 5 megapixel camera (just like the Google candy Nexus One) and an OLED display, apart from a front facing camera, a stunning dual-core processor with more RAM and a touch-sensitive case. The iPhone 4G releases between May and July 2010. There is a good chance that Apple's new phone may have removable battery. Check out the image below and let us know what you think.

According to Goldman Sachs' Robert Chen, "Apple’s going to put a lot of innovation, not just on the hardware, but also on the software of the new iPhone." Rumours suggest the new iPhone has a sensitive back case, similar to the touch panel used for the Magic Mouse (which has a touch-sensitive solid plastic shell instead of mechanical buttons). Motorola announced an Android based phone called 'Backflip' which can be controlled via a touchpad on the back of the screen. We can expect a similar design on the new iPhone.

According to Chen, the new iPhone will go into production in April and should be available to consumers in June or July. But as per Steve Dowling, an Apple spokesman, "We’re not going to comment on rumors and speculation." The iPhone is Apple's second largest source of revenue, second only to the laptops. A dual core processor on the iPhone 4G would knock the socks off the 1Ghz powered Nexus One.
