Wheelchair Blitzkrieg

The Zenith wheelchair, a design by the Mechanical Engineering Department at the University of Alberta, is fit with tank-like treads to climb up stairs under the user's own power.

The treaded design combines with strong, lightweight tech like an aluminium back frame and a Herman Miller-inspired carbon fibre seat to create a beastly machine that's not too cumbersome to actually wield. Still, if the design actually works - there's no working prototype yet - we have to wonder: Why didn't everyone put tank treads on wheelchairs already? And why the heck is Johnny 5 receiving better medical care than the citizens of humanity? [thedesignblog via coroflot via io9]
