A recent study, “Reduced mixing time in stirred vessels by means of irregular impellers" (S. Başbuğ, G. Papadakis, and J. C. Vassilicos
Phys. Rev. Fluids 3, 084502 – Published 21 August 2018), shows fractal shapes can mix better with lower torque which would mean reduced power consumption for mixing machines using fractal shaped implements. One study suggests that torque can be reduced by 14% and these mixing devices are employed in a wide range of applications in the chemical, pharmaceutical and process industries. 21 Steiros et al.1 and Başbuğ et al.2 introduced fractal impeller blades created with a modification of the regular, rectangular-shaped impeller blades. The design of the novel fractal blades was inspired by the fractal plates tested in wind tunnel experiments by Nedić et al.22 who demonstrated that fractal plates generate higher turbulence intensity in their wake compared to square plates.

We have made 9 different spoons for cooking which can be seen at fractalspoons.com.

Examples are shown at attachment #1 and attachment #2 better mixing and lower torque and they look really good. We are not accustomed to seeing fractal shapes in tools but fractal antennas are in many cell phones we just cannot see them.

We have also made masonry hoes with fractal designs to improve mixing and reduce torque and will be testing them in the near future please see attachment #3

We also have filed provisional patent.
