A hydraulic motor comprises at least two tanks each having an arrangement of upper and lower telescoped, relatively reciprocating tubular members. The lower tubular member extends from the bottom of the tank, the upper tubular member being guided during reciprocation. A liquid contained in the tanks is capable of floating each upper tubular member relative to the lower tubular member associated therewith. Each upper and lower tubular member arrangement forms a variable volume chamber containing a gaseous fluid. The variable volume chambers communicate with each other for equalizing the pressure therebetween. The tubular members of the respective chambers being alternately floated as the respective tanks are filled with and emptied of the liquid to cause commensurate, alternate reciprocation of the upper tubular members. A mechanical energy source is provided due to such a reciprocation.
