Deep-sea sponge's 'zero-energy' flow control could inspire new energy efficient designs

The deep-sea Venus flower basket sponge can filter feed using only the faint ambient currents of the ocean depths, no pumping required, new research reveals. This discovery of natural 'zero energy' flow control could help engineers design more efficient chemical reactors, air purification systems, heat exchangers, hydraulic systems, and aerodynamic surfaces. https://ift.tt/nWFMj7c
