Filaments modeled after Earth's fastest falcon

The peregrine falcon is delivering some “real innovation and benefits” to aeronautics researchers in England, where they’re copying the bird’s feathers to 3D print filaments that mimic its ability to sense airflow changes, according to this 3D Printing Industry article. It could help create safer, more aerodynamic, and fuel efficient airplanes.

How polar bears can lower our heating bills

It makes sense: Want to design the ultimate insulation? Look to the polar bear. That’s what a student at the Royal Academy of Art did to create Plyskin, according to this Materia article. The three-layered material mimics the makeup of a bear’s skin and, most importantly, is being developed biobased and recyclable materials.

Fern fractals inspire fast flow that saves energy

Solving the challenge of creating smaller, more efficient batteries enables greater use and application of renewable energy systems. Inspired by the microgeometry of fern leaves, scientists created electrodes that can store more power per unit area while reducing the path that electrons have to follow to complete a circuit, according to this Nature article. Small geometries not only increase efficiency, but are amenable to powering small, wearable devices, or large, regional systems.

Resilient architecture that helps fight climate change

Resilient architecture that helps fight climate change

Thomas Knittel of McLennan Design has written a thought provoking article in Arcade magazine about his work on an orphanage project in Haiti. Beyond appreciating the form and process inspirations from nature (the strength of tree branching and the filtering ability of bark), I was intrigued by the ecosystem-level thinking that became ingrained in the project. There are not many project teams that are learning resilience lessons from population biology case studies and applying that idea to their buildings, and I found it heartening and valuable.

Insect wing flexibility principle adds major turbine oomph

Insect wing flexibility principle adds major turbine oomph

Lessons from nature don’t always have to be complex. The simple principle of “add flexibility rather than rigidity” helped researchers at Paris-Sorbonne University demonstrate the potential to yield 35% more power from wind turbines. While the challenge now lies in scaling the prototypes, abstracting the simple design principle opened up new ways of thinking about blades.

New technology could help us emulate nature’s brilliant shapes

The key to many of nature’s strategies is using shape rather than material. Emulating those shapes, especially at the nano-scale, has proven challenging. This new platform technology has the potential to leverage the shape of nature’s surface textures to add functionality to a wide variety of surfaces by building from the bottom up.

Uniting around a common challenge for all life on Earth

Uniting around a common challenge for all life on Earth

In this article, David Suzuki challenges us to use the forest as a sophisticated model of energy production to move beyond our “primitive idea of burning” in order to survive. He reminds us that all species share similar challenges in our quest to survive and thrive, and a biomimicry approach to the climate change challenge would give us all the answers we need.

Super-powered batteries modeled after human gut

A new way to help keep batteries powered has been discovered–inside the human gut. According to this BBC article, scientists have mimicked the villi of the small intestine to help trap material that have broken off inside batteries, allowing them to continue powering the battery. This could help develop a battery with five times the energy density as traditional batteries.

Inexpensive irrigation inspired by natures

Inexpensive irrigation inspired by natures

An ancient system for moving water to fields for irrigation is suggested as an inexpensive way to use these underground duct systems for a source of heating and cooling buildings in the Sahara. The Fouggara system uses underground and aboveground channels, according to this Science Direct article. A ground-air heat exchanger uses very little driving energy. Pumping air through these channels is suggested as a source for heating, cooling, and ventilation.

Pulling energy form indirect ‘sunlight’

Plants may teach us how to collect solar energy even from devices that are not, themselves, wholly exposed to sunlight. Scientists in Korea have demonstrated that light receptors in the underground root systems of thale cress are activated by so-called “stem-piped light” from the plant’s sun-exposed shoots, according to this Science Magazine article.
