Help me make sense of
ths story please:
Scientists have built a backpack that turns the spring in your step into electricity for your cell phone. And, they say, it's more comfortable than the average backpack.
This device would allow soldiers, rescue workers, and field scientists ? all of whom use several electronic instruments such as cell phones and GPS locators ? to leave bulky and heavy replacement batteries at home.
That thing on your back is better than carrying a few batteries? Particularly with the rest of your gear? I'm confused?
