Calla Lily



based on the design of a simple flower, the Calla Lily.

Some examples of man made technologies which have been designed from natural processes and nature are detailed below;

Rotational equipment – previously rotational equipment design had little changed by way of development in over 4000 years, and remained inefficient.  Design flaws include drag resistance, low output, energy inefficiency and noise.  New technology based on the design of a simple flower, the Calla Lily,  was developed.  Progress required an understanding of vortical fluid dynamics. the calla lily’s shape, the flower’s centripetal spirals assist with the flow of liquid.

Seaweed – was noted to change its shape to let the water go by and that nature repeatedly uses 3-dimensional centripetal spirals, oriented toward the centre, for liquid flows. From this it was determined that the most efficient way to move water seemed not to be a straight line, but a curve known as Phi, also known as the Golden Mean, or Fibonacci progression.  When used in water flow design, the water at the outer edges of the spiral is pulled toward the centre, reducing or eliminating any drag or resistance.  Nature’s simple design reduces energy requirements, less resistance, less noise and vibration.

We are learning more and more what nature has to offer us in terms of design, designs for devices and systems are increasingly based on biomimicry.  Nature has already done the leg work, we just need to look closer at how it does what it does.  When we understand it we can use that knowledge to design more efficiently.
