ABSTRACT:
A solar engine including a vessel disposed for motion along a predetermined path and having an array of discrete expandable and contractable chambers disposed in spaced relation along the path. The vessel contains relatively non-expandable fluid while the chambers each contain a relatively expandable and contractable fluid which is of lesser density than the non-expandable fluid. The chambers along a predetermined section of said vessel are maintained at a cooler temperature than those chambers exposed to solar energy. The chambers exposed to solar energy are caused to expand upon heating of the fluid therein, causing displacement of the non-expandable fluid. At the same time, the cooled chambers are caused to contract in response to cooling of the fluid therein and permitting the inflow of an additional quantity of non-expandable fluid into the cooled section of the vessel. As a result, the cooled section of the vessel contains a greater amount of non-expandable fluid, producing a mechanical unbalance which in turn produces movement of the vessel along the path.
