Abstract
An electric power generation system is disclosed. The electric power generation system includes: a first string and a second string configured to be pulled; a first portion of a bobbin configured to rotate in a direction when the first string is unwound from the bobbin as the first string is pulled; a second portion of a bobbin configured to rotate in the direction when the second string is unwound from the bobbin as the second string is pulled; and an electric power generator having a rotor wherein the rotor is mechanically coupled to the bobbin. The pulling of the second string causes the first string to retract and the pulling of the first string causes the second string to retract.
