Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
50 words
A method of generating electricity which comprises: preparing a solution of liquid ammonia and an element which dissolves and ionizes in such liquid ammonia to produce cations of the element and electrons which are solvated by the ammonia, and moving said solution containing such solvated electrons through a magnetohydrodynamic generator.
Claim 2
Independent Claim
50 words
A method of generating electricity which comprises: preparing a solution of liquid ammonia and an element which dissolves and ionizes in such liquid ammonia to produce cations of the element and electrons which are solvated by the ammonia, and moving said solution containing such solvated electrons through a magnetohydrodynamic generator.
Claim 3
Dependent Claim
35 words
The method of claim 1, which comprises pressurizing the solution and heating the solution to produce expansion of the solution, and said expansion of the solution produces movement of the solution through the magnetohydrodynamic generator.
Claim 4
Dependent Claim
38 words
The method of claim 1, wherein the solution containing the solvated electrons is moved through a magnetohydrodynamic generator with motion produced at least partially by reason of volume expansion occurring on the mixing of ammonia with molten metal.
Claim 5
Dependent Claim
89 words
The method of claim 1, wherein the solution is circulated through the generator with the solution flowing from an upstream side of the generator through the generator to a downstream side of the generator thence to be recirculated to the upstream side of the generator, solution is collected at one temperature and pressure on the downstream side of the generator, and the collected solution is recirculated to the upstream side of the generator after being pressurized and heated to produce expansion of the solution causing movement through the generator.
Claim 6
Dependent Claim
16 words
The method of claim 1, wherein the solution is a concentrated solution of an alkali metal.
Claim 7
Dependent Claim
100 words
The method of claim 1, wherein the solution is a solution of an alkali metal, the solution is circulated through the generator with the solution flowing from an upstream side of the generator through the generator to a downstream side of the generator thence to be recirculated to the upstream side of the generator, the solution is collected at one temperature and pressure on the downstream side of the generator, and the collected solution is recirculated to the upstream side of the generator after being pressurized and heated to produce expansion of the solution which produces movement through the generator.
Claim 8
Independent Claim
139 words
A method of generating electricity, wherein a concentrated solution of an alkali metal in liquid ammonia is circulated through a magnetohydrodynamic generator, the alkali metal dissolving and ionizing in such liquid ammonia to produce cations of the alkali metal and electrons which are solvated by the ammonia, the ammonia solution flowing from an upstream side of the magnetohydrodynamic generator through the generator to the downstream side of the generator, and thence being recirculated to the upstream side of the generator, the solution being collected at one temperature and pressure on the downstream side of generator and the collected solution, on being recirculated to the upstream side of the generator, being pressurized, and then heated, to produce, as a result of such heating, expansion of the solution, said expansion of the solution producing movement of the solution through the generator.
Claim 9
Independent Claim
139 words
A method of generating electricity, wherein a concentrated solution of an alkali metal in liquid ammonia is circulated through a magnetohydrodynamic generator, the alkali metal dissolving and ionizing in such liquid ammonia to produce cations of the alkali metal and electrons which are solvated by the ammonia, the ammonia solution flowing from an upstream side of the magnetohydrodynamic generator through the generator to the downstream side of the generator, and thence being recirculated to the upstream side of the generator, the solution being collected at one temperature and pressure on the downstream side of generator and the collected solution, on being recirculated to the upstream side of the generator, being pressurized, and then heated, to produce, as a result of such heating, expansion of the solution, said expansion of the solution producing movement of the solution through the generator.
Claim 10
Independent Claim
111 words
A method of producing electricity utilizing solar energy and by means of a magnetohydrodynamic generator which comprises: collecting within a collecting chamber a solution of liquid ammonia and an alkali metal, with the alkali metal having dissolved and ionized in such liquid ammonia to produce cations of the alkali metal and electrons which are solvated by the ammonia, heating said solution in said chamber to produce expansion of said solution, directing said solution on such expansion through a magnetohydrodynamic generator, collecting the solution at a lower temperature and pressure after such has passed through the magnetohydrodynamic generator, and with pumping and pressurizing of the solution, returning the solution to said chamber.
