Mitigating Climate Change by Nature Inspiration

Different Levels of Bio-mimicry

We must learn the cure of climate change from Nature: Nature Inspired

One biological machine produces CO2 and the other consumes it. This is the way how nature works but we are destroying this cycle by cutting forests and increasing the CO2 emissions and this needs to STOP!!


Nature-inspired products available in the market at present 

The products shown in possess specific nature mimicked functions, nature inspired architectures or a combination. Many nature mimicked functional products have developed and many of these are now available in the market, for instance a gecko tape inspired from gecko feet, which helps geckos to adhere on the surface; a noiseless ceiling fan inspired by fins of whales is introduced by “LG” in India, Velcro inspired by the cocklebur seeds, which has hook-shaped spikes that interlock with looped fabric; and superhydrophobic windscreen inspired by the lotus leaf effect (highlighted by green circle in).

Artificial Photosynthesis Inspired by Natural Synthesis

Artificial intelligence-based robotics inspired by human brain

Brain-inspired computing is a smart computing system working with designed intelligence algorithms to make decisions such as self-driving vehicles, robotics, and face-recognition systems, etc. Algorithms enable the computer to intelligently respond to signals received from the sensor through communication with other devices and saving memory similar to the human brain. Recently a human-like mobile robot has been reported to work dexterously in the laboratory day/night like a chemist.  It is enabled with safety features to work with humans in the same laboratory or working space making it a prime example of a human collaborative robot (COBOT). The intelligence algorithms are major features of a machine capable of making its own decisions like a human being.
