Sugar gives humans energy, so why not batteries, too? Researchers at Virginia Tech are developing what amounts to fuel cells, but with a sugar solution rather than hydrogen. Other attempts at sugar batteries have been made, but this one has an energy density that blows other versions out of the water. That means it can run for a much longer time before refueling is necessary.
"Sugar is a perfect energy storage compound in nature. So it's only logical that we try to harness this natural power in an environmentally friendly way to produce a battery," says Y.H. Percival Zhang, associate professor of biological systems engineering at Virginia Tech.… Read more
