Sony concepts need no batteries

Sony has recently unveiled the Odo range of concepts that will probably sell well if they ever make it into production. Some of the offerings from the Odo range include the Spin ‘N’ Snap camera, requiring you to place a finger through each hole while spinning the device around its center. This action turns a dynamo while creating just enough power to capture the next photo, pretty much the same way like how old school cameras work. The Push POWER Play device is powered as long as you drag it across the table, giving you the ability to watch movies or images without the need for batteries or an AC outlet. Guess these are but a natural extension of the wind-up torchlights that we see available these days.
