Abstract: The present invention relates to a process for generating movement and energy on the basis of the flotation of bodies, being based on the use of a receptacle provided with a valve for intake and a valve for expulsion of a determined liquid, preferably water, there being situated in the interior of the receptacles a hollow body or a body filled with a material whose density is lower than that of the said liquid but with the special feature that the distance between the two lateral contours of the receptacle and the interior body referred to is minimal and this is for the purpose that the volume of liquid necessary to cause the floating of the said interior body is also minimal, therefore, depending on the variable volume of liquid circulating through the receptacle, thanks to the said intake and expulsion valves, the floating body effects an ascending-descending movement which, by means of conventional elements interposed, is used to transform the said alternating movement into a circular movement or into any
