Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source—such as the distance from a power plant to street lamps on a remote highway—a lot of energy is lost during transmission.
The invention relates to a machinery transmission device and a solar energy system for driving a lighting device to rotate in west and east directions.
