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.

This means that, with the application of a well-adapted design (19.8%), a daily profit of approximately €5,800 could be achieved.
