  • Patent number: 10384813
    Abstract: A method, operable in the presence of ambient cosmic rays, is provided for braking a craft upon approach to a planet, moon or other space body, e.g. in preparation for landing. Deuterium-containing particle fuel material is projected in a specified direction outward of the craft, which interacts with both the cosmic rays and their principal decay product muons to generate energetic micro-fusion products that produce a braking thrust on the craft for a specified trajectory. The micro-fusion products may push directly against the craft, e.g. upon a pressure plate, or upon a sail or parachute connected to the craft, to decelerate the craft. A prepositioned automated landing system at a landing site may project the fuel material toward the craft based on telemetry tracking of an incoming craft and likewise directly disperse the material cloud to form a braking cushion at the landing site.

  • Patent number: 8736199
    Abstract: The temperature rise due to the backstreaming electrons is canceled by an equal and opposite fall in temperature at the surface of the cathode due to the conduction of heat deposited at the surface immediately prior to the microwave pulse by a pulsed laser focused to uniformly illuminate the cathode surface. Variations in temperature across the surface of the cathode attributable to the non-uniform spatial distribution of the backstreaming electrons may be compensated using a second laser pulse fired during the RF pulse to maintain constant thermal power input across the surface of the cathode during the RF pulse. This second pulse can also be used to compensate for the time-dependent rate of decay of temperature due to conduction of the heat deposited by the first laser into the body of the cathode.

  • Patent number: 7831008
    Abstract: A system for fueling a plasma includes a gyrotron for radiating microwave energy into a waveguide. Also included is a module having a deuterium-tritium (DT) fuel pellet, a diamond, quartz or sapphire window, and a pusher medium located between the pellet and window that is made of frozen deuterium (D2) and metallic particles. With the module in the waveguide, the gyrotron is activated. Radiation from the gyrotron is then directed into the waveguide and through the window to cause the inducement of current in the metal particles, causing the particles to become hot. The absorbed microwave energy is then transferred to the pusher medium by conduction resulting in a gaseous expansion of the pusher medium. This ejects the pellet from the waveguide and into the plasma.

  • Publication number: 20090310731
    Abstract: A single-pass heavy-ion fusion system includes a new arrangement of current multiplying processes that employs multiple isotopes to achieve the desired effect of distributing the task of amplifying the current among all the various processes, to relieve stress on any one process, and to increase margin of safety for assured ICF (inertial confinement fusion) power production. Energy and power of the ignition-driver pulses are greatly increased, thus increasing intensity of target heating and rendering reliable ignition readily attainable. The present design eliminates the need for storage rings. Further innovations are to give the HIF (heavy ion fusion) Driver flexibility to drive multiple chambers in the most general case of different total distances between the linac output and each of the various chambers. Using multiple chambers steeply decreases the pro-rata capital investment and operating costs per power production unit, in turn decreasing the cost of power to users.

  • Publication number: 20090122940
    Abstract: Methods for low-temperature fusion are disclosed. In one embodiment, a symmetrical crystal lattice including a plurality of deuterons either absorbed or embedded in a heavy-electron material is selected. The method provides alternatives for initiating a vibration mode involving the deuterons on the crystal lattice that induces them to converge. The oscillating convergence of the deuterons is enhanced by the charge screening effect of electrons. The electron screening effect is in turn enhanced by the high effective-mass associated with the selected materials. The vibration modes are excited, for example, by applying an electrical stress, a uniform magnetic field, mechanical stress, non-uniform stress, acoustic waves, the de Haas van Alphen effect, electrical resistivity, infrared optical radiation, Raman scattering, or any combination thereof to the crystal lattice.

  • Publication number: 20080304611
    Abstract: A method, using the reaction between Lithium and neutron to produce Tritium, is used to sustain Deuterium-Tritium nuclear fusion long enough to produce electrical power. This method uses Deuterium-Tritium nuclear fusion to produce energy. The energy produced by Deuterium-Tritium nuclear fusion is used to heat water to produce steam. The steam produced is used to operate steam turbine. The steam turbine operates electrical generator to produce electricity. The electricity generated is used as electrical power. In the Deuterium-Tritium nuclear fusion, Deuterium is naturally abundant, but Tritium is naturally scarce. This invention provides a method to supply Tritium. That is, Lithium, which is naturally abundant, is added as fuel. The neutron produced by Deuterium-Tritium nuclear fusion will react with Lithium to produce Tritium. Thus it sustains the Deuterium-Tritium nuclear fusion long enough to produce fusion energy, which is then turned into electrical power.
