An electromechanical composite system is proposed for storing electrical energy (current) which had been acquired primarily from renewable energies. To this end, according to the invention a current storage means in electromechanical systems is proposed, said means comprising alternatively connectable motors and generators depending on requirements, said motors and generators connected to travelling weights. The current acquired from renewable energies is fed to said motors, which in turn lift the travelling weights from depths, such as a shaft, by way of a cable winch, and thereby impart potential energy to said weights. As users require electrical energy (current), the travelling weights are dropped back into the shaft, wherein said weights convert the released potential energy to electrical energy by way of the cable hoist and the cable winch together with the generators. |
