I also reported (back in 2008) how researched had been conducted into using sound waves to charge mobile phone batteries: http://trewmte.blogspot.com/2008/12/sound-waves-could-power-cell-phone.html . This year, 2010, a new invention has been developed that requires twirling a mobile phone battery (with the use of one finger) 130-revolutions generating 25-minutes standby time and 2-minutes talk time. The idea for this invention comes from Designers: Song Teaho & Hyejin Lee at http://www.yankodesign.com/2010/01/04/cheers-to-finger-power/. The invention is promoted using the following photoimages.

This invention is unliklely to replace the battery charger (PSU) but as a 'Green' (environmental) back-up power charging alternative, the idea may find merit with the mobile phone handset manufacturers. No doubt there will be those who may criticise the invention based upon 130-revolutions generating only 2-mins of talktime. However, 260-revolutions generating 4-minutes of power need not be spent 'yakking' away on the mobile phone, but perhaps sending text messages. Or it might be useful where a user's standard battery has discharged but may need to make an emergency call (999 etc); perhaps this design may have synergy with that old adage "necessity is the mother of invention".
