Stanford students create a prosthetic leg that works for only $20

The JaipurKnee Project started when Biomedical Device Design and Evaluation students at Stanford University were tasked with creating a prosthetic leg that was as awesome sturdy as it was amazingly cheap. What they came up with is the leg you see above, which allows this gentleman to walk naturally again, and the prosthetic limb only costs $20.

While impressive advances in prosthetic technology have created arms that function almost as well as the ones lost — and even new eyes to see — obtaining said artificial limbs is expensive, and not a viable solution for most of the rest of the world. Legs like the JaipurKnee Project produces, on the other hand, while not as technically impressive, restore the basic function of natural walking, which in itself is impressive enough.
