The invention relates to a method for obtaining energy from the Earth's gravitational force, in particular for producing a rotational movement, which method is designed in such a way that working bodies (7) are introduced into a liquid column (1) or into communicating liquid columns (1) by introducing devices (11), the action of which is oriented toward one another, counter to the water pressure, in such a way that the force/energy needed for the introduction into the (one) liquid column (1) is at least partly compensated by a force/energy resulting from the same or other liquid column (1). A device for producing rotational movement uses the method according to the invention.
