Recently I found a promising new wind mill design for an urban wind turbine based on the magic of the nautilus (logarithmic) spiral.
To get some imagination about how the flow will behave in this kind of turbine I decided to do a quick flat design of that spiral and to print a CW and CCW version of it. The results were indeed surprising ...
This is a run of my counter rotating double wheel test mill:
I guess it also will be usable for decorative or kinetic art purpuses.
What you get:
- easy-to-customize version of a Nautilus windmill
- easy-to-print Mobile and wind wheel
