The present invention provides a system of using compressed air as force source, comprising: compressed air jet engines, which use high/ultra-high pressure compressed air as a jet working medium, a compressed air production/supply device to economically, environmentally and quantitatively produce, store and supply the high/ultra-high pressure compressed air, and a controller. The compressed air jet engines are equipped on an airplane, rocket, submarine, train, or other moving carrier for aviation, aerospace, navigation and/or ground travel, comprising an air tank and air engines for generating power. The air engines comprise a main air engine for generating thrust, and a plurality of auxiliary air engines for reducing the air (or seawater) resistance and the sliding friction with air (or seawater) during the carrier movement to facilitate the speed-rising and energy-saving, and for improving the lift force of airplane wings to facilitate airplane short-range or vertical take-off/landing, etc.

Asteroid redirection systems are provided that use cosmic ray and muon-catalyzed micro-fusion. These systems include a micro-fusion propulsion system providing thrust for redirecting an asteroid, as well as micro-fusion electrical generation powering an ion drive. The systems deploy deuterium-containing fuel material as a localized cloud interacting with incoming ambient cosmic rays to generate energetic fusion products. Dust or other particulate matter in the fuel material converts some cosmic rays into muons that also catalyze fusion. The fusion products provide thrusting upon the asteroid, or when produced near turbines facilitates electrical generation, which can then power an ion drive.

By subjecting a volume or a bulk of a working material to a body force per unit mass, such as gravity, inertial forces, electric forces, or magnetic forces, the perceived specific heat capacity of the volume of the working material can be increased or decreased as desired. The artificial modification of the perceived specific heat capacity of a material can be employed in a thermodynamic cycle to convert thermal energy directly into useful mechanical work, and vice versa.

This patent seeks to describe a design and method of production of a solid state radiometric thruster for the intent of producing a new method of powered flight at varying scales of operation. By using modern nano-manufacturing techniques it is possible to create surface microstructures of the same size as the mean free path for gases at any desired operational pressure, allowing for radiometric forces to be harnessed for propulsion even when the total part dimensions are several orders of magnitude larger than would normally allow this effect to create a noticeable force.

A system and method for generating a force from a voltage difference applied across at least one electrically conductive surface. The applied voltage difference creates an electric field resulting in an electrostatic pressure force acting on at least one surface of an object. Asymmetries in the resulting electrostatic pressure force vectors result in a net resulting electrostatic pressure force acting on the object. The magnitude of the net resulting electrostatic pressure force is a function of the geometry of the electrically conductive surfaces, the applied voltage, and the dielectric constant of any material present in the gap between electrodes. The invention may be produced on a nanoscale using nanostructures such as carbon nanotubes. The invention may be utilized to provide a motivating force to an object. A non-limiting use case example is the use of electrostatic pressure force apparatus as a thruster to propel a spacecraft through a vacuum.

The invention relates to an electromagnetic toroidal impeller in the field of physics applied to electromagnetism. The invention comprises a cylindrical arrangement of superconducting antennas (9) which are separated by a dielectric (8) over a superconducting cylindrical pate (7) and exposed in a resonant cavity (6). The radiation in the cavity is incident on the force ring having a superconducting surface (4) containing ferrite (11), the coolant (5) introduced through the pipes (1) flowing through the toroidal interior of same. The force received in the ring (4) is transmitted via the supporting members (3) to the support (2). The cavity is thermally insulated with insulation (12) and is cooled with the liquid (10) through the pipes (14). The invention provides a device capable of generating driving force from the conversion of the energy available in electromagnetic waves that are contained in a resonant cavity.

An electromagnetic energy momentum thruster has a cavity resonator and an electromagnetic radiation source for emitting an electromagnetic wave in evanescence into the cavity resonator. The electromagnetic wave produces a greater electromagnetic field amplitude and a greater electromagnetic radiation pressure on a primary interior surface area of the cavity resonator than on a secondary interior surface area of the cavity resonator. The difference between the electromagnetic field amplitude on the primary interior surface area and on the secondary interior surface area of the cavity resonator forms a highly directional electromagnetic energy momentum tensor and provides a highly directional general relativistic metric tensor. As a result, a force is produced on the cavity resonator in the form of a thrust or an acceleration that propels the device in a direction substantially perpendicular to the primary interior surface area.
