"WOODS HOLE, MAIn an unprecedented breakthrough in the development of portable and renewable human-driven energy sources, an MBL (Marine Biological Laboratory) biomechanics expert who studies how muscle moves skeletons in fish and frogs has invented a backpack that gives new meaning to the term power walking. In a paper published in the September 9 issue of Science, Lawrence C. Rome, a University of Pennsylvania biology professor who spends his summers conducting research at the MBL, and three colleagues describe the mechanics of, and physics behind, the Suspended-load Backpack, a piece of gear that will one day enable field scientists, hikers, explorers, soldiers, and disaster workers to convert mechanical energy generated by walking with a heavy load on their backs into electricity." <more>
