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.

Claims

1. An electric power generation system including:

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, wherein 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; and

an electric power generator having a rotor wherein the rotor is mechanically coupled to the bobbin.

2. A system as in claim 1, wherein the first string has length such that a large motion can be used to pull the first string.

3. A system as in claim 1, wherein the second string has length such that a large motion can be used to pull the second string.

4. A system as in claim 1, wherein the first string and the second string comprise a single string wherein the middle the single string is coupled to the bobbin and a first end of the single string is used as the first string and a second end of the single string is used as a the second string.

5. A system as in claim 1, wherein a shaft is coupled to the bobbin.

6. A system as in claim 1, wherein the rotor of the electric power generator is coupled to the shaft.
