We develop a dynamoelectric device which charges electricity to an electric double layer capacitor with rotating a handle by a human power. The structure of this device is as follows. Attached an arm of a handle to the output axis of a geared-motor, electricity occurs with rotating the handle. Electricity that occurred is stored to an electric double layer capacitor through a diode to prevent inverse currents. Handle is rotated with 1 time of pace in a second, and current flows 2 amperes on the average, this device can accumulate electricity from 0.5 bolts to 2.5 bolts in 100 seconds to a capacitor of 100 farads. It is possible to move a small size motor for a model more than 2 minutes with this electricity quantity. By using this device, importance of electricity energy can be caused experienced.
