Abstract: The invention is based on the use of pneumatic systems for the conversion of human power of children's play. The energy of the compressed air can then be converted to electricity for purposes such as lighting and communication. This provides a low-cost, low-resource means of generation of electricity, especially for use in developing countries. This embodiment is an extension of the invention by generating electricity from the pedaling action of an exercise bicycle while playing a video game and includes the use of a stationery exercise bicycle, a video gaming system, a monitor, a game controller including buttons/joystick on the bicycle, electromechanical and biomedical sensors, an artificial intelligence-based pre-processor for signals from the controller, and a pneumatic or electromechanical energy conversion device for producing electricity. The electricity produced can be used to quantify the play or exercise involved, and to provide incentives to encourage sustained play or exercise.
