An apparatus and process for lifting heavy objects by capturing mechanical work from the buoyant energy of liquid displacement. The apparatus comprises one or more bodies of liquid, collapsible liquid-displacement displacement vessel, and lifting force transfer means to the object, in use, the weight of the object to be lifted is secured onto the lifting platform and leveraged by the force transfer means to draw gas into the displacement vessel. Once the displacement vessel is full of gas, it will reverse the force transfer means to lift the object to the top of the liquid. Once the lifted object is secured at the elevated position, a gas release valve releases the gas and the displacement vessel collapses and sinks back down to the bottom of the liquid and the process can be repeated as necessary.
