Power Generation from Gravitational Potential Energy in daily vertical displacement

Increasing demand for energy, clarify the importance of finding ways to efficient consumption and also reduce losses and unnecessary energy consumption. Displacements in the direction of gravity are one of the most important sectors that could be argued where unnecessary energy is consumed. In this situation, energy is consumed to counteract the force of gravity whether going up or coming down. These systems include: elevators, escalators, electric vehicles and other devices that work of force is aligned with gravity. By designing a system that controls the movement in this direction consistent with the user's request we can achieve to reduce unnecessary energy consumption. Therefore, in this paper we introduce a torque transmission system by keeping a constant speed that can meet conditions of displacement in the vertical direction. This system eliminates the consumer actuator and also makes exploitation and energy production from this force possible.
