Now you can operate a miniature steam engine to actually generate electricity using this Model #70G Steam Engine with AC Generator. Steam engines are fascinating to observe and experiment with as they convert energy from one form to another. This steam engine and AC generator combination is built by hand one at a time using the same manufacturing processes since 1923! It features quality workmanship and materials, like a seamless nickel-plated brass boiler, nickel-plated engine, hand-painted 3" flywheel, sand double-acting oscillating cylinder engine.
The Model 70G steam engine is powered by a 110-volt 400-watt electric heater in the 2.5" x 6" boiler to provide a low-cost, continuous power supply. The electric energy is converted to thermal energy in the boiler; the thermal energy is converted to kinetic energy in the steam, and the kinetic energy is converted to mechanical energy in the cylinder. The mechanical energy of the pulley on the rotating flywheel is then harnessed to drive a 6-volt AC generator. The pulley on the steam engine or generator can also be used to operate simple mechanical machinery. Operating this steam engine and generator is a fun way to learn about energy conversion for a school or science fair project! This steam engine and AC generator comes fully assembled and includes an operating manual. The size is approximately 14" x 12" base and 9" high.
