A backpack that generates its own electricity may soon allow rescue workers, explorers, and soldiers to power their equipment while on the go, a team of scientists reported today.

The backpack will derive its power from the motion of the person carrying it.

The invention, known as the suspended-load backpack, frees handheld computers, cell phones, and dozens of other devices from the constraints of limited battery life and the reach of the power grid.
