An electrical power generating apparatus for generating electrical power using a generator connected directly or indirectly to a flywheel is disclosed. The apparatus comprises items such as platforms, protrusions, generators, flywheels and other components. The platforms are configured to be laid on a surface and easily allow an object, e.g., a vehicle to traverse over the platforms. Each protrusion is configured to move downward and upward through apertures located in a top portion of the platform. The protrusions may interact with reset members. The protrusions move in a linear/angle downward/downward-upward motion when the object pushes/strikes/depresses the protrusions. Each protrusion can be connected in an operative manner to a shaft via a gear, and/or to a lever which is connected in an operative manner to shaft, thereby rotating the shaft by converting linear motion to rotational motion. A generator, flywheel, and gearbox can be coupled to one or more shaft.
