The ReRev system hooked up to these elliptical machines, shown Thursday at the Pohl Recreation Center at the University of North Texas, collects the users’ kinetic energy to generate electricity.
Kristen Budd pumps her legs, her ponytail bobbing, as she works out on an elliptical machine at the University of North Texas recreation center. It’s similar to other workouts the UNT junior has had before — but today there’s a difference. Every time Budd moves her legs, her kinetic energy is harnessed by the machine, sent to a metal box on a wall nearby and converted into usable electricity that could supply wattage to the building’s television monitors or light bulbs.
