Slippery when wet: Fish, seaweed to help cargo ships reduce fluid friction

Shipping engineers are looking to fish and seaweed for new strategies to reduce fluid friction and help cargo ships slide through the ocean water.

To reduce drag, fish and seaweed secrete lubricants that form a slippery layer, helping their bodies move efficiently through the ocean.

Researchers suggest cargo ships could use a similar strategy by deploying lubricant-infused surfaces marked with cavities. By continuously filling the cavities with lubricant, a slippery layer is formed over the surface of the ship's hull.

The strategy has been tested before, with success, but until now, researchers had not characterized the physics that make the fluid friction-reduction strategy work.
