The annual Ig Nobel award ceremony is one of, if not our absolute favorite awards shows of the year. For those who don't know, it awards prizes to serious scientific studies about, well, offbeat things. This year's crop of winners include the inventors of a wasabi alarm clock, a study that shows we make better decisions when we have to pee, and the discovery of a beetle that likes to mate with a certain brand of Australian beer bottle.
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.
