Pitt Designs New Wheelchair Powered by Compressed Air
From: ECN Magazine - 04/07/2017

A new waterproof motorized wheelchair that runs entirely on compressed air
was unveiled today at Morgan's Wonderland, a 25-acre theme park in San
Antonio, Texas. The park was built specifically for individuals with
disabilities, and 10 of these chairs will be available to patrons at the
venue's new splash park, Morgan's Inspiration Island, when it opens later
this spring.

Designed, developed and constructed at the University of Pittsburgh Human
Engineering Research Laboratories (HERL), the patent-pending PneuChair uses
high-pressured air as an energy source instead of heavy batteries and
electronics. The chair weighs about 80 pounds overall and takes just 10
minutes to recharge, compared to eight hours to charge an electric mobility
device.

The maximum distance on one fully charged tank is around three miles, about a
third of the distance an electric chair can travel before it needs to be
recharged.
