Abstract: A relatively hot and a relatively cold chamber are air evacuated and contain a low boiling point liquid. The temperature differential between the chambers results in a vapor pressure differential between the chambers. The vapor pressures inside the chambers transmit a vector force to a movable wall of each of the chambers. The vapor pressures in the chambers are equalized intermittently by an intermittent communication between the chambers. The chambers are positioned relative to each other so that the movable wall of one chamber transmits an opposing vector force to the movable wall of the other chamber. This brings the walls to a position which is determined by the the resultant of the opposing vector forces upon the walls. When the resultant of the vector forces changes during the intermittent communication between the chambers the movable walls change their position. The movements of the walls between different positions perform useful work through standard mechanical links to a force receiving means.
