Humans and batteries--and indeed most other things in the natural world, operate on largely similar principles.
Energy is generated somehow, stored, and expended for work. It's only the details that separate these processes, but the gap might shrink with the advent of biobatteries.
As ExtremeTech reports, researchers at Virginia Tech have developed a working sugar-powered fuel cell with energy density greater than that of current lithium-ion batteries.
Sugar, or more accurately glucose, is an excellent source of energy in biological beings, as it's energy-dense and easy for a plant or animal to process. In humans, during aerobic respiration, … Read more
