The submitted patent, "Devices for Utilizing Energy Components in the Relative Motion of Bodies in Liquid Media During Displacement by Flow Dividers," demonstrates significant, energy-efficient potential. Observations of ships on the Main-Danube Canal led to energy analyses and the applicant's own experiments.
