The Conveyor1 will take the object vertically to the top of the device with speed control by the lifting unit (1), then the object will get transferred from Conveyor1 to Conveyor2. The Conveyor2 will carry the object to the free falling unit (2) area with speed control. The object will fall in the free falling area with the help of permanent magnets; the object will get attached on Conveyor3, which will give drive to the rotating wheel. The object gets detached from Conveyor3 and gets transferred to Conveyor4. Conveyor4 will take the object back to Conveyor1 with speed control. The falling object is again carry on the top and same cycle is continuously rotating the rotational wheel which further generate the electricity. By such way multiple devices are synchronized to give continuous power to the respective rotating wheel of each machine, wherein one main shaft passing through the rotating wheel of multiple machines.

A harvesting system that includes a dynamo with a rotor and a stator, a push magnet that is attached to the rotor or is a part of it, a moving magnet that moves from a first position to a second position, and a push back magnet. The repulsive magnetic force that is exerted by the moving magnet on the push magnet in the second position is greater than that force in the first position. The moving magnet moves from the first position to the second position and causes the rotor to rotate from a dynamo first position to a dynamo second position that causes the dynamo to produce current. When the moving magnet moves back to the first position the dynamo returns to its first position due to magnetic force that the push back magnet exerts on the push magnet.

An exercise device with controllable training modes includes a base, a first exercise mechanism, a second exercise mechanism, and an operating mechanism. The first exercise mechanism has a first gear member. The second exercise mechanism has a second gear member. The operating mechanism has a third gear member. When the third gear member is at a first position, the third gear member meshes with the first gear member and the second gear member to form a linked state, so that the first exercise mechanism and the second exercise mechanism are operatively linked and coupled and swing in opposite directions. When the third gear member is at a second position, the third gear member is disengaged from either the first gear member or the second gear member or both to form a free state, so that the first exercise mechanism and the second exercise mechanism individually swing.
