By almost any account, the 2012 Olympics will be the most high-tech ever, from the actual starting guns to the microsecond camera finishes. But the pre-Olympics are even more high-tech, as athletes increasingly turn to advanced video and biomechanical data analysis to track their performances and train more efficiently.
Holographic video is sort of the holy grail of video display technology right now. Stereoscopic 3-D is fine and everything, but it basically works by tricking the brain into seeing that 3-D depth via two offset 2-D images--hence the occasional headaches associated with current commercial 3-D displays. Holographic video, by contrast, creates images that are really three-dimensional, no glasses or headaches required.
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.
