1. A vapor transport device comprising: a tube; a first cap positioned at a first region of the tube, a second cap positioned at a second region of the tube, and a piston positioned between the first cap and the second cap so as to divide the tube into a first chamber of variable size that extends between the first cap and the piston and a second chamber of variable size that extends between the piston and the second cap; a drive shaft connected to the piston and extending through the second cap, wherein the drive shaft is configured to translate the piston between the first and second caps; and a plurality of one-way valves, wherein each of the first cap, the second cap, and the piston comprises one or more of the plurality of one-way valves, and wherein the plurality of one-way valves are oriented so as to permit vapor to flow from a position outside of the tube into the first chamber, from the first chamber to the second chamber, and from the second chamber to a position outside of the tube, but to prevent vapor flow from the first chamber to a position outside of the tube and from the second chamber to the first chamber.
