When it comes to discovering sources of renewable energy, Penn State engineering professor Bruce Logan is outstanding in his field. A corn field, to be precise. He’s developed a fuel cell that uses corn stems and stalks -- called “stover” -- to generate electricity. His fuel cell turns 70 percent of the corn’s cellulose content into sugar. Then, basically, it feeds the cellulose to anaerobic bacteria. These highly efficient little organisms consume the sugar and release electrons as a byproduct with no solid materials left over as waste...
