Water take heed: Liquids are now at the mercy of a breakthrough material from Bell Labs. Flip an electric switch and the material acts like a sponge. Flip again and it behaves like a rain slicker. Applications could turn up wherever liquids meet solids (read: practically everywhere). Lead researcher Tom Krupenkin envisions near-frictionless torpedoes, self-cleaning windshields and more efficient batteries.
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.
