There are two generators associated with the KidWind Wind Experiment Kits.<\/p>\n

Both the KidWind Basic Wind Experiment Kit<\/a> (KW-BWX<\/nobr>) and the KidWind Advanced Wind Experiment Kit<\/a> (KW-AWX<\/nobr>) and the associated classroom packs come with the KidWind Wind Turbine Generator with Wires<\/a> (KW-GEN3<\/nobr>). The KidWind Wind Turbine Generator has a diameter of about 3.2 cm and a length of about 3.4 cm (including the shaft). The shaft is 2 mm in diameter. This generator is also the one installed in the nacelle of the KidWind MINI Wind Turbine with Blade Design<\/a> (KW-MWT<\/nobr>).<\/p>\n
