A small mechanical device or engine that moves or operates in response to changes in atmospheric pressure.
From baro- (pressure) + -motor (Latin motor 'mover'). A rare scientific term from the late 19th century combining two elements to describe pressure-sensitive mechanical systems.
Scientists experimented with baromotors as part of exploring whether they could harvest energy directly from atmospheric pressure changes—a dream that never quite worked but represents the kind of creative engineering that does eventually lead to real innovations.
