This is the final product, and it worked well after I change the motor problem. I successfully made a product that can generate energy by human hand and move it to the battery. When you roll the handcraft, you create kinetic energy and it converts to electric energy when it comes to the motor part. The wire attached to the motor moves electric energy to the battery. The thing that I should improve is it doesn’t create much energy so it takes a long time to make the battery fully charged.

The impact of the project will help waste of battery, therefore, it could help us from littering alkalic battery littering.The potential client will be all people who has used battery.
