Energy harvesting from an exercise machine

In modern day gyms, machines such as treadmills, rowing machines and elliptical are essentials and will always be used by users trying to burn off calories by exerting and producing energy which are being dissipated out primarily as heat. However, if capturing of this energy is made possible from th...
