1. A method of producing a nuclear fusion reaction, comprising:starting and completing a single cycle of a nuclear fusion reaction, the single cycle includingevacuating a reaction chamber to a pressure that is lower than about 10−3 torr;inducing a pulse of (i) a first reactant into the evacuated reaction chamber through a first reactant port and a pulse of (ii) a second reactant into the evacuated reaction chamber through a second reactant port, wherein the first reactant and the second reactant are independently selected as comprising deuterium or tritium;converging the first reactant with the second reactant at a target cathode for colliding and fusing the first reactant with the second reactant to create a heat energy, the converging creating a higher reaction density at the target cathode rather than relying on random collisions, and includingcreating an electrical field in the reaction chamber by applying a voltage that is selected from the group consisting of about 10 kV, about 11 kV, about 12 kV, about 13 kV, about 14 kV, about 15 kV, about 20 kV, about 25 kV, about 30 kV, about 35 kV, about 40 kV, about 45 kV, about 50 kV, about 60 kV, about 70 kV, about 80 kV, about 90 kV, about 100 kV, about 200 kV, about 300 kV, about 400 kV, about 500 kV, about 600 kV, about 700 kV, about 800 kV, about 900 kV, about 1 MV, about 2 MV, about 3 MV, about 4 MV, about 5 MV, about 10 MV, or any voltage therein, or range of voltages therein, in increments of 1 kV across an anode surface positioned in the interior of the reaction chamber and a surface of the target cathode positioned in the interior of the reaction chamber, the surface area of the target cathode ranging from about from about 1.00×10−10 m2 to about 1.00×10−6 m2, the electric field ionizing the first reactant to generate a cationic first reactant and ionizing the second reactant to generate a cationic second reactant; and,establishing a negative charge on the target cathode for attracting and converging the cationic first reactant and the cationic second reactant at the target cathode for colliding and fusing the cationic first reactant with the cationic second reactant to create the heat energy. 2. The method of claim 1, wherein the first reactant is deuterium and the second reactant is tritium. 3. The method of claim 1, wherein deuterium is both the first reactant and the second reactant. 4. The method of claim 1, wherein tritium is the first reactant and tritium is the second reactant. 5. The method of claim 1, further comprising adjusting the pressure in the evacuated reaction chamber to range from about 10−4 torr to about 10−9 torr. 6. The method of claim 1, further comprising adjusting the pressure in the evacuated reaction chamber to range from about 10−6 torr to about 10−9 torr. 7. The method of claim 1, further comprising:replacing the target cathode with a replacement target cathode to complete a first cycle of the nuclear fusion method and provide the replacement target cathode for a second reaction cycle.
