From time to time we post stories about appropriate technology that changes people’s lives. The Lily Impeller is an amazing example of biomimicry that shows the power of working with nature. Biomimicry related research is leading to an array of appropriate technologies and now hundreds of products like the Lily Impeller are entering the market.
From the Biomimicry Institute: “Biomimicry is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies. The goal is to create products, processes, and policies—new ways of living—that are well-adapted to life on earth over the long haul.”
“Nature likes spirals, from whirlpools or hurricanes, to the way sap flows up a plant, to the shape of a human heart. Inventor Jay Harman, of the engineering research and product design firm PAX Scientific Inc., used this archetypal shape from nature to design a “frozen whirlpool” as the rotary part of a machine or pump. Harman’s frozen whirlpool, about the size of your hand, can stir ten million gallons of water in a storage tank with just a couple of light bulbs’ worth of power. This design keeps water tanks clean, without the use of chlorine or other chemicals. Harman is working now to scale up his frozen whirlpool to clean the air of a whole city.”
“Inventor Jay Harman of PAX Scientific describes the motivations and inspirations behind his innovative Lily Impeller, and the need for businesses to embrace sustainable design. Read the full story on Harman’s inventions at http://www.flypmedia.com/issues/23/#5/1
