Thermosiphon engine and method

摘要

A thermal engine in which two interconnected columns of liquid form a closed path with one of the columns being heated and the other being cooled thereby to induce circulation of the liquid in the closed path. A fluid actuated rotary member is placed in the path and power can be taken from a shaft connected thereto. The column in which the liquid rises can be heated by sunlight, especially by attaching panels to the column, or it can be heated by combustion, and the column in which the liquid moves downwardly may be cooled by radiation or convection or by passing a cooling fluid therealong.
