    Hand Crank Bulbs
    ​

    Turning of a modified bicycle crank, visitors convert physical work into electricity. The energy from “pedaling” turns a three-phase windmill alternator.  By pushing one of the three buttons, visitors choose to illuminate a 60W incandescent, a 6W incandescent, or a 6W LED. This body on experience allows visitors to feel the tremendous difference between the energy required to light an LED vs. an incandescent bulb.
