Penn Professor Perfects Perambulatory Power Pack
 Penn biology professor Larry Rome, utilizing the concept of converting mechanical energy into electrical energy, has designed a backpack harnesses the motion of an individual walking at a normal to strong gait (2.5 - 4.0 mi./hr.) with its inherent bounce to produce electrical energy (of up to 7.4 watts) within the uniquely designed backpack.
The backpack can "... power a cell phone, GPS tracking device, or an MP3 player." as reported by The Philadelphia Inquirer staff writer Faye Flam.
The original article found in the journal Science describing the mechanism appeared in the September 9, 2005 issue.
