With this research we demonstrate that the experiment of the free fall of bodies can be repeated, but with different objectives than those that motivated Galileo Galilei to perform an experiment using the inclined plane. The hypothesis that guided our investigation was: The experiment of the free fall of bodies is susceptible to change its purpose. To confirm this hypothesis, it was necessary to invent a technological prototype that works when a suspended body falls towards the center of the Earth; in the case of the experimental processes that allowed us to confirm our hypothesis, the body to be attracted was the mass of water contained in one or more containers. After having confronted the theories with the results of the experimental processes, the hypothesis was confirmed, as expressed in the main conclusion of the experiment: By using a sash as a means of transmission of gravitational potential energy, with a flow rate of 10, 757 L/min, with a height of 8.56 m, we will be able to obtain 11, 56 volts DC. The results of the present research have made possible the granting of a patent.
