This is fascinating! I have a family member who was--for a time--mostly confined to a wheel chair, due to spinal nerve damage. Every bump and jolt would cause him a lot of pain. The design of the large wheels on the wheelchair shown in this video just might eliminate a lot of that problem. It's another example of how engineering continues to evolve in ways that can make our quality of life just that much better.
