A project from a couple of Masters students in mechanical engineering at Brigham Young University, FlexLegs is sort of like a cross between crutches and Oscar Pistorius's super-fast lower-leg prostheses. They promise to allow those with lower leg injuries to walk, run, tackle steps, and more. Say the creators: "If we can help a person with no legs to run, why can’t we help a person with an injured leg to walk?"
When I came into the office hobbling like Igor last week, thanks to a Muay Thai-related sprained ankle, any regular boss would’ve just offered a “get well soon.” Instead, my boss tells me we have some high-tech, ergonomically designed crutches left from Best of What’s New, and won’t I please take them for the holiday weekend? Sometimes it’s good to work at PopSci.
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.
