Reddit reviews The Shark's Paintbrush: Biomimicry and How Nature is Inspiring Innovation

Have you ever tried pouring water out of a bottle normally vs spinning the bottle to make vortex and pouring it out. The water will pour out faster because of the swirling.

This is an example of biomimetic fluid dynamics. It turns out water doesn’t travel most efficiently in a straight line like we usually try and force it to do. The most direct path of fluids in nature is a curving one. So this design induces a similar swirl to the water so it can drain faster than a more seemingly direct route.

This is the book where I learned this stuff from. It’s quite interesting.
