Residue-free, mechanical current storage unit mounted in e.g. cuckoo clock, has a weight, and steel drum filled with desert sand, in which the stored gravitational force is converted into alternating current without residues/pollutants

摘要

The current storage unit comprises a weight (i) made of cast iron or concrete, connected through a steel cord (h), a motor (b), and a steel drum (d) which is filled with desert sand. If necessary the stored gravitational force is converted into alternating current (AC) without residues or pollutants. The entire machine is manufactured from the commercial products. Power of about 1-100 kWh can be generated from the rotation of a speed gear (c1). The maximum height of the weight is 10 meters.
