Combining light-emitting diode and gravity light to generate power continuously

Abstract

Alternatives to kerosene lamps have been explored for people who do not have access to electricity in developing regions. GravityLight (GL) uses stored gravitational potential energy to power light-emitting diode (LED). Both LED and GL are reviewed for main characteristics and mechanisms. An improved GL system is proposed targeting continuous power generation, the design principles of which are established from the law of Conservation of Energy. The system might be made possible by energy storage and bringing in other forms of energy/work. The proposed solution is evaluated to be feasible.
