Note that no overall efficiency can be given; instead this can be determined from the moment of force and the optimum airspeed. To select the best bladed rotor for a location, this info can be combined with the regular windspeed at a height comparable to the one of the wind energy harvester; eg 10m).\n\n{| class=\"wikitable\" style=\"text-align: center; width: auto;\"\n! bladed rotor type\n!
