摘要： The invention includes a solar collector subsystem and a heat engine. The solar collector system uses heliostat mirrors, a parabolic mirror, and a convex concentrator lens or compound parabolic concentrator to gather a large amount of solar energy into a very intense beam. The beam is used to vaporize an injected droplet of working fluid, whereby multiple opposed pistons responsive to the vapor formed reciprocate to produce electric energy by means of linear electric generators. The heat engine includes a chamber having three orthogonal sets of opposed pistons, wherein each piston is independently axially reciprocable and coupled to a linear electric generator. One piston is provided with an axially located window that admits the concentrated solar beam from the solar collector subsystem into the chamber of the heat engine. Another piston is provided with an injector that selectably injects a water drop into the center of the chamber where it can be vaporized by impingement of the concentrated solar beam.

摘要： An engine is disclosed comprising a chamber defined by at least one fixed wall and at least one movable wall, the volume of the chamber variable with movement of the movable wall; an injector arranged to inject liquid into the chamber while the chamber has a substantially minimum volume; apparatus through which energy is introduced that is absorbed by the fluid which then explosively vaporizes, performing work on the movable wall; and apparatus which returns the movable wall to a position prior to the work being performed thereon so the chamber has the substantially minimum volume, substantially evacuating the chamber of vaporized fluid without substantially compressing the vaporized fluid. Also disclosed is a method of converting energy from one form to another in a system comprising confining a quantity of substantially unexpanded liquid within a chamber; adding energy to the system, so as to heat the liquid sufficiently to vaporize the liquid and expand a resulting vapor; and receiving mechanical energy from the expanding vapor in a form of movement of a wall of the chamber responsive to the expansion. In a variation, a method of converting energy from one form to another by passing a working material through a closed liquid-vapor thermodynamic cycle, comprises expanding the working material from a liquid phase into a vapor phase by addition of heat; recovering heat from the working material in the vapor phase so as to condense the working material from the vapor phase into the liquid phase to await expansion; and adding the recovered heat to working material awaiting expansion, without changing the phase thereof.

摘要： A method of converting thermal energy into another energy form using a thermodynamic cycle is disclosed, the method including the steps of: pressurizing a working fluid; supplying thermal energy to heat the working fluid from a liquid or substantially liquid state to a supercritical fluid state; in a first expander, substantially isentropically expanding the working fluid to yield energy in the other energy form; separating the expanded working fluid to form a first portion of the fluid diverted to a second expander and a second portion of the working fluid diverted to bypass the second expander; in the second expander, substantially isentropically expanding the first portion of the working fluid to yield energy in the other energy form; condensing the expanded first portion of the working fluid to a liquid or substantially liquid state; and recombining the first and second portions of the working fluid to be recirculated in the cycle.
