Meet the EcoMill: a self-powered treadmill with a curved surface that provides you with a tough workout and generates energy to charge your phone or mp3 players. The EcoMill treadmill is a green alternative to motorized treadmills. It has an onboard generator system that produces power for the display and can charge a phone or iPod.
The EcoMill is compatible with ReRev systems, so it can turn your kinetic motion into renewable energy. Like what you see? You can find more information here.
