• German engineers test silent propellers to save marine life without losing speed The MinKav project uses high-speed cameras to visualize bubble collapse, aiming to make silent propulsion a standard for the global fleet. • German researchers are launching a new project to tackle one of the ocean’s loudest problems. • Ship propellers create massive noise that disrupts marine life. • This interference breaks the communication, feeding, and mating patterns of marine mammals. • Now, a team at HAW Kiel is developing new propeller designs to silence the seas. • The state of Schleswig-Holstein is fueling this effort with a €390,000 grant.
