Drive device driven by buoyancy and thermal energy

摘要

Provided is a drive device efficiently converting thermal energy of a vertical high-temperature tank and a vertical low-temperature tank into a drive force. The volume variable container (11) at a vertical high-temperature tank (1) side is supported on the forward side of a horizontal communication pipe (7) in the travel direction, and the volume variable container (12) at a vertical low-temperature tank (2) is supported on the rear side of the horizontal communication pipe (7) in the travel direction, and enclosed gas is transferred by a pressure difference between the volume variable container (11) and the volume variable container (12). A travel belt 4 travels with respect to an insulation wall (3) due to a total buoyancy difference (F1−F2) between the total buoyancy (F1) of the buoyancy of the volume variable container (11) and the total buoyancy (F2) of the buoyancy of the volume variable container (12).
