These energy-recycling stairs are a creative alternative to the structure's traditional form.

Although we're told it's good for our health, taking the stairs can be a difficult and oftentimes painful experience. Shortness of breath and a heightened heart rate can't compete with the knee and joint pain people with mobility issues face while tasked with this daily chore.

To combat the aches of climbing the stairs, without eliminating the exercise benefits, a team at Georgia Tech and Emory University have developed this unique climbing system that helps put a spring in every step. The staircase stores energy from people descending, and uses that energy to compress itself when people are ascending, an innovation that makes climbing the stairs 37% easier ton the knees than before.
