The requirement for the initial design was to produce enough electrical energy to charge a smartphone at normal - thus low - wind speeds (Bft. 3).
But the airfling's architecture enables you to scale and change the resulting power for your requirements.
You live at a place where the wind blows more often and stronger? Make the airfling smaller! Change the rotors airfoil design.
You need more power? Stack multiple rotors! Or increase the rotor's diameter. There's no need to print all parts all over. Simply change rotor arms, print out more parts or change the rotors.
