Biomimicry studies nature and uses it as a source of inspiration to create innovative solutions to human challenges. It’s an approach that’s based on the premise that living organisms have evolved highly efficient mechanisms over millions of years to adapt to their environment.
In the words of biologist Frederic Vester, it’s the only company that has never gone bankrupt in over 4 billion years, thanks to its evolutionary success and sustainability. However, the concept of biomimicry has evolved significantly over time. It was popularized by Janine Benyus in her book "Biomimicry: Innovation Inspired by Nature" (1997), although the practice of imitating nature dates back to ancient times.
Ancient Greeks like Aristotle were already studying nature to understand its workings and apply them to technology and medicine. In the modern era, biomimicry has gained momentum as both a scientific and design discipline, with researchers and professionals like Janine Benyus, Julian Vincent, and Michael Pawlyn leading the way in developing significantly more sustainable and efficient technologies and processes.
For example, researchers have observed how termites build their mounds, which maintain a constant temperature through an intelligent design of natural ventilation. This knowledge has been applied in bioclimatic architecture to create buildings that regulate their temperature naturally, without needing artificial climate control systems.
However, one of the major areas where biomimicry is making a significant impact is in the development of sustainable energy solutions. The energy transition is one of the greatest challenges of our time, and nature offers a variety of models that can be adapted to reduce their environmental impact.
Inspired by photosynthesis, the natural process by which plants convert sunlight into chemical energy, the next generation of solar cells is designed to do just that. A notable project in this field is Daniel Nocera's Artificial Leaf. These artificial solar cells mimic the structure of leaves to convert solar energy into electricity more efficiently. They utilize materials and structures that replicate natural systems of energy capture and storage, and they’re used on residential rooftops and in small industries.
Another noteworthy example is the WhalePower project, which applies the design of whale fins, with their protrusions called tubercles, to the blades of wind turbines. This improves aerodynamics, allowing more wind to be captured and converting kinetic energy into electricity more efficiently. These turbines are used in wind farms to generate electricity more efficiently.
There are also groundbreaking initiatives like BioPower Systems' BioWave, which draws inspiration from the structure of seaweed to generate electricity from the flow of water. These generators are set up in coastal areas, providing clean, renewable energy. Meanwhile, the Eastgate Center in Zimbabwe uses natural ventilation principles observed in termite mounds, significantly reducing air conditioning use and energy consumption. This system is primarily used to cool buildings for improved energy efficiency.
In conclusion, biomimicry offers a promising approach to reducing environmental impact through nature-inspired innovation. By observing and continuously learning from natural processes, we can develop sustainable energy technologies and systems.
