Abstract
A self-contained electro-mechanical device incorporating a hand crank wound main spring mechanism coupled with gears to a rotating magnet inside an iron core with wound copper wire for the purpose of generating electricity. An external AC adaptor can use the generator as a motor to wind the main spring without the need to use the hand crank. An internal electronic circuit is connected to the motor/generator and mechanically coupled using a unique solenoid and clutch mechanism to prevent the main spring from turning until an external load is detected. When packaged in the form of two standard C or D size batteries this invention can be installed into devices currently using electro-chemical batteries. An internal LED light enables the device to be used as a self-contained flashlight. A mini USB connector is incorporated for charging cell phones and powering numerous devices compatible with USB power.
