Gaining access to your gym or office building could soon be as simple as waving a hand at the front door. A Hunsville, Ala.-based company called IDair is developing a system that can scan and identify a fingerprint from nearly 20 feet away. Coupled with other biometrics, it could soon allow security systems to grant or deny access from a distance, without requiring users to stop and scan a fingerprint, swipe an ID card, or otherwise lose a moment dealing with technology.
Biometric security is often focused on the more boring anatomical parts, like the pads of the fingers (ehhh) or the eyes (who cares). So little attention has been paid to the security possibilities of the butt. Well, not anymore: researchers at the Advanced Institute of Industrial Technology in Tokyo have come up with a car seat that measures the precise contours and pressures left by your posterior.
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.
