ShakEnergy battery is a different type of concept battery that can be recharged by a manual operation without the need of using any kind of components. This AA sized nickel metal hydrate battery is charged through shaking it. It also can be charged through an electrical battery charger. The ShakEnergy concept battery has five components inside, rechargeable Ni-mH battery, shaft, coiled bobbin, permanent magnet and rubber shock-absorber. The capacity of the battery is about half of the usual AA size battery and the main electricity is produced by the bobbin. When the battery is shaken, the permanent magnet moves up and down through the shaft and center of the bobbin, thus produces the electricity. The rubber base absorbs the shock, as well as helps the magnet to bounce back.
I can’t write in a straight line on a blank paper, the result would be slanting downward or upward.

This device features a ballpoint pet lid with a laser component that emits light onto the paper to guide you to write better, it creates lined paper effect on a blank sheet. Place the cap at the top of the paper, the top corner. The laser can be slid up or down the lid and rotate 360-degree to fit your requirements, you can also adjust the space between the lines.

The cell phone market over the years has turned out to be a segment with the least shelf life, thereby a constant process for manufacturers to come up with new models. Today cell phone is not just an instrument to make and receive calls but far beyond that. The new walkman phone Premiere 3 by KDDI for Sony Ericsson, slated for spring release is a powerhouse so to say. It features a 3″ VGA screen, auto focus camera, and a memory of 2GB and weighing a meager 113gms, and quite compact in size. The colors are quite vibrant and with video in demand feature and also remote control for walkman, it sure is a model to look out for. There’s no info on pricing yet.
