Environment-friendly slot cars circuit

Abstract

This paper presents an environmentally friendly cars system that does not require batteries or the mains to power the cars. Instead of simply using energy from those sources, players have to pedal bicycles in order to keep their cars running. The faster a player pedals, the faster his car runs. The system parameters were adjusted so that a considerable physical effort is required in order to make a car run. Associating electric energy generation with considerable physical effort is pedagogical and makes this system very suitable for science fair events
