Dolphins are helping reduce CO2 emissions. Propeller coatings mimicking their skin improved oil tanker fuel efficiency.

  • Dolphin skin is covered in mucus and microstructures

  • Reduces hydrodynamic drag

  • Coated propellers used 2%

The $20k propeller cut CO2 emissions by 900 tonnes and saves $140k annually, per ship. Researches are working on scaling production to other maritime shipping industries. Thanks Flipper, PhD!
