Description

F03G covers mechanical power generation systems based on springs, weights, inertia, or unconventional energy sources that do not fit within other prime mover classifications. This includes devices such as clockwork motors, gravity-powered mechanisms, flywheel energy systems, and mechanical systems exploiting elastic deformation or rotational inertia. The subclass is designated for innovative mechanical-power-producing devices and mechanisms using energy sources not covered elsewhere in the F03 division (such as hydraulic, pneumatic, wind, or solar systems). It serves as a residual classification for novel mechanical propulsion or power generation technologies outside established categories.
