Gravity-Based Power Generation Apparatus for Emergency

Abstract

A gravity-based power generation apparatus comprises a main body, which comprises a cylinder and coils. When the magnetic ball is affected by gravity, and vertically moves in the cylinder inside, coils generate electrical power by the electromagnetic effect. The power supports to a lighting unit and a USB unit. The apparatus is used as an emergency device, supported a gravity-based flashlight and a mobile USB power. The apparatus is implemented by 3-D printer. The experiment results show idea and apparatus are effective.
