www.strans.wordpress.com and find out all about s-trans. It is a Continuously Variable Reduction Mechanism made of sprockets & chains. My full title is: Rotating Planetary System - Torque Transfer Device - using sprockets and chains with multiple inputs. One of my features is I have multiple inputs which means it can be driven by up to 4 electric motors or up to 4 wind turbines which greatly increases the power put into the transmission. www.graemeeddington.wordpress.com
