Researchers at the Massachusetts Institute of Technology have come up with a new system for generating electricity that could show promise for powering small airplanes. “The potential energy density of this power source is on the same scale with petrochemical energy sources, and it is orders of magnitude higher than commercial lithium ion batteries,” Michael Strano, an MIT professor of chemical engineering, told AVweb this week. “It definitely has the potential to power airplanes of any size.”
