Scientists at the Massachusetts Institute of Technology may have created the ultimate green battery technology: They’ve engineered a virus that could potentially form a battery that would outlast and out power those available today. The batteries could be used to power small electronic devices such as cell phones and MP3 players. In the future, they could also be used to power automobiles. The M13 virus used to create the batteries infects only bacteria, so it is harmless to humans. The recent discovery builds
