At the University of Kansas they're generating electrical energy in their recreation facility.

The David A. Ambler Student Recreation Fitness Center is retrofitting 15 elliptical machines with ReRev devices made by Florida-based SunQuest energy that draw on kinetic energy created by people’s workouts and reroute that energy back into the building’s electric grid — pushing back against electricity supplied by conventional carbon-based power supplies.
