Students can build their own motor/generator. Standing over 45" high from base to top of blade, the KELVIN® Experimental Wind Turbine provides students the opportunity to test rotor and blade designs by varying the rotor sweep, blade size and blade shape to change the electrical output of the generator. Test rotor output with the included multimeter or see how many LEDs are lit. Students can also fold a cardstock model house and create their own LED circuit to plug into the wind turbine generator. Includes: motor/generator, gearbox parts, hub, corrugated plastic for blades, PVC stand with sturdy base, multimeter, LEDs, breadboard, printed house layout, wire, terminals, and instructions. A box fan or similar fan on a stand is required but not included.
