The electron has been good to us. It has christened an entire field of both theoretical exploration and practical devices -- electronics -- and has allowed us to leverage its most simple property, charge, to create complex devices and processing methods. But a group of researchers in Colorado think we're selling ourselves short. By tapping the more complex properties of entire atoms, the field of atomtronics could completely rewrite the book on information processing.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
