All Charged Up Engineers Create A Battery Made of Wood

"The big idea behind Joe's Big Idea is to report on interesting inventions and inventors. When I saw the headline "An Environmentally Friendly Battery Made From Wood," on a press release recently, I figured it fit the bill, so went to investigate."

"The battery is being developed at the Energy Research Center at the University of Maryland in College Park."

"I really wasn't sure what a wood battery would look like. I knew you could make a battery out of a potato and wires, so I figured maybe they were doing something similar with a block of wood."
