The invention claimed is: 1. A system for moving objects, comprising: an input for receiving the objects; a helical screw means receiving objects from the input; means for containing the objects on the helical screw means and means for forming a plurality of movable compartments in cooperation with the helical screw means, the helical screw means structured to rotate about a longitudinal axis in a fixed longitudinal position in the containing means so that the helical screw means does not move longitudinally relative to the containing means, and the means for forming a plurality of compartments comprising a plurality of platens, each platen positioned between adjacent flights of a same helix of the helical screw means to form a compartment of the plurality of compartments; and means for driving the helical screw means wherein the driving means comprises means for igniting the objects within selected compartments formed by the platens, the casing, and the helical screw means to initiate the combustion of the objects and drive the helical screw means to rotate about a longitudinal axis of a shaft of the helical screw means. 2. The system of claim 1, wherein the plurality of platens are coupled together in a continuous loop and the means for containing comprises a casing in which the helical screw means is mounted, the casing having an elongate opening for receiving the chain of platens, each platen forming a wall between flights of the helical screw means that moves along the longitudinal axis as the helical screw means rotates. 3. A system, comprising: an input for receiving objects; a helical screw means receiving objects from the input; means for containing the objects on the helical screw means and means for forming movable compartments in cooperation with the helical screw means; means for driving the helical screw means; an output for receiving objects from the helical screw means; wherein the means for forming movable compartments on the helical screw means comprise a plurality of platens coupled together in a continuous loop and the means for containing the objects on the helical screw means comprises a casing in which the helical screw means is mounted, the casing having an elongate opening for receiving the chain of platens, each platen positioned between flights of the helical screw means to form a wall between flights of the helical screw means; and wherein the driving comprises means for igniting the objects within selected compartments formed by the platens, the casing, and the helical screw means to initiate combustion of the objects and drive the helical screw means to rotate about a longitudinal axis of a shaft of the helical screw means. 4. A device, comprising an enclosure having a first opening and a second opening; an elongate shaft mounted in the enclosure to rotate about a longitudinal axis of the shaft while not moving longitudinally in the casing, the shaft comprising a helical member extending outward from the shaft and along a length of the shaft; a plurality of platens coupled together and engaged with the helical member and, along with the casing forming a plurality of compartments that move as the helical member rotates with the shaft, each platen sized and shaped to fit between adjacent flights of the helical member to form a movable wall as part of the compartment defined by the wall, the helical member, and the casing; and an igniter that is adapted to ignite a combustible mixture within selected compartments of the plurality of compartments and thereby drive the shaft to rotate.
