Wind Power Demonstrator
This wind power generator can be used to demonstrate the generation of electricity by a wind-powered turbine. Wind produced by the hand-cranked fan subsequently turns a second fan connected to a generator. When the fan rotates, it produces electricity and lights up a small LED and a voltmeter. Instructions included.

Hydroelectric Power Station
Ideal for classroom demonstration, this hydroelectric power station model allows students to directly observe the process of conversion of water flow to electrical energy that occurs in hydroelectric power plants. The water turbine is mounted on a plastic base together with a dynamo, newton disc, lamp, LED, and a two-way selecting switch. The switch selects delivering power to either a lamp or a Newton’s Color Disc. The LED can be removed if you instead want to draw current from the 4 mm output terminals. Includes instructions.

Hero’s Engine
Hero’s Engine demonstrates the principle of jet propulsion. The apparatus consists of a small Erlenmeyer flask with a rubber stopper and two tubes with tangentially oriented jets. A collar is provided around the flask to hang it above a heating source. When water boils inside the flask, steam escapes the jets and the flask spins.
