Crank operator


Hand cranks are used to generate currents, which in turn power various receivers. Stage personnel/audience members are made to perform different amounts of work/work at different levels of difficulty in order to power the corresponding receiver. The audience gets an impression of how much work/energy is required in order to operate a particular device, and also that certain feats are only possible with an appropriate receiver. The exhibit may feature hand cranks, a treadwheel, a bicycle or a “pedalo” as devices for generating energy. The exhibit is intended to appear somewhat mechanical and is reminiscent of a time machine from 1900. The exhibit generates energy that can be stored, transformed, transported or used to run different consumer devices (e.g. a pump).

Unique proposition

The exhibit is primarily available as hands-on equipment. It goes without saying that a stage version needs to provide new (visual) stimuli.
