786th FSS: Going green and making green with Spark Tank idea
Master Sgt. Joseph McTaggart, Ramstein Air Base Southside Fitness Center noncommissioned officer in charge, walks on one of the new environmentally friendly treadmills at Ramstein Air Base, Germany, Oct. 4, 2019. The treadmill functions entirely on the individuals own energy. As the individual moves, the treadmill transfers the individual’s energy into usable energy which is put back into the power grid.
