Abstract
Abstract A system is disclosed for converting one form of energy into an alternate form of energy by means of a low-temperature process. A liquid flow loop with two vertical columns that are interconnected at the top and bottom circulates a fluid. A convective flow of this fluid is established by heating the fluid in one of the columns and cooling the fluid in the other column to establish a weight differential between the fluid in the two columns. An electric generator is placed on this loop so that, as the fluid flows through the loop and through the generator, electrical energy is generated. This electrical energy is used to electrolize a second fluid, such as a solution of sulphuric acid, into gasses such as hydrogen and oxygen. The gasses so generated are used to increase the rate of flow of the fluid, and consequently the rate of electric energy production. In one embodiment, the gasses are injected into the rising column of the fluid to increase the weight differential between the fluid in the two columns and enhance the convective flow of that fluid. These gasses, which contain chemical energy, are then removed from the loop at the top of this column. Alternatively, the gasses can be accumulated at high pressure, and the pressure used to inject a volatile fluid into the loop.
