描述
This wind power generator demo is a great way to get students thinking about alternative energy. Unlike other products, this unique demo can be used in the classroom, as students provide the "wind" power by turning a handle and cranking a geared propeller. The "wind" created by this action turns the blades of another propeller placed opposite and electrical energy is produced. The voltage is displayed on a voltmeter and a red LED light illuminates.
