The present invention generally relates to a propulsion device. More particularly, the invention relates to a propulsion device configured to generate a thrust utilizing a magnetic field.
It is well known in the art for vehicles to utilize turbines, propellers or other engines to create thrust and movement. Airborne vehicles lose efficiency because they require moving large volumes of air to generate lift which creates losses due to the friction of that air over vehicle and engine part surfaces. Vehicles require burning expensive and environmentally unfriendly fuels, such as jet fuel. These conventional airborne vehicles can be loud thus requiring extensive insulation to have a quiet interior conducive to conversation. Further, conventional air vehicles do not allow for operation in multiple mediums, for example a single vehicle capable of operating under water, in the air or in the vacuum of space.
A device configured to generate a thrust utilizing the earth's magnetic field is provided. The device includes a platform for supporting structure, a tube forming a closed loop, and a mechanical pump or blower. In one embodiment, the tube is filled with an electrically charged fluid, such as ions. A portion of the tube is shielded so as to contain electro-magnetic forces therein. The mechanical pump or blower is configured to move the charged fluid within the tube, through the earth's magnetic field where in the movement of the charged fluid that is orthogonal to the earth's magnetic field a thrust is generated.
A vehicle having the propulsion device described above is also provided. The vehicle may include sensors and a controller configured to adjust the amount of charged fluids within the tube, as well as change the speed at which the charged fluids flow within the tube and/or control the amount of shielding of the moving charged fluid. The controller is further configured to pivot the tube relative to the platform so as to change the vector of the thrust.
A device 10 for generating a thrust utilizing the earth's magnetic field is provided. The device 10 includes a tube 12 forming a closed loop, and a circulator 14. The device may be mounted to a platform 16 for supporting structure. The tube 12 may be filled with a charged fluid, such as ions (as indicated in the hatched section of the tube in
With reference first to
The tube 12 is shown adapted to fit within a bottom recess 22 of the platform 16. The tube 12 forms a closed loop. It should also be appreciated that the orientation of the tube 12 shown in the drawings is not limiting to the scope of the invention herein. For instance,
In a first embodiment, the tube 12 is filled with a charged fluid, or ions having a net positive or negative charge. For instance, the tube 12 may be sealed, so as to prevent ions from escaping. Thus, the tube 12 may be replaced as an entire unit. Alternatively, the tube 12 may be filled prior to the assembly of the device, or may be filled before each use. In such an application, the tube 12 may include a port 24 having a cover 26 operative to open or close the port 24. The charged fluid may be introduced into the tube 12 through the port 24 in a similar manner as filling a gas tank with gasoline.
The tube 12 includes a shielded portion 28 and an unshielded portion 30. The shielded portion 28 may form ⅕ of the circumference of the tube 12, however the shielding provided is merely exemplary and it is anticipated that the tube may be shielded otherwise. For instance,
The shielded portion 28 is configured to prevent electro-magnetic forces from interfering with/countering the electro-magnetic forces generated by the unshielded portion 30. Any electro-magnetic shield currently known and used, may be adapted for use herein, illustratively including a Faraday cage. Accordingly, the shielded portion 28 may be formed from a material such as iron, copper, steel, or any other electrically conductive material that would shield/reflect electromagnetic waves.
The interior of the tube 12 is generally a smooth surface so as to maximize the efficiency of fluids flowing within the tube 12. The tube 12 may also be configured to prevent deionization of the charged fluid flowing within the tube 12. It should be appreciated by those skilled in the art that preventing deionization increases the efficiency of the propulsion device 10 by reducing the frequency that the ion generator must be actuated, or the speed at which the ions are propelled within the tube 12. Deionization may result from a charged particle reacting with the inner surface of the tube 12, and from the product of out-gassing from the tube 12. As used herein, out-gassing refers to the act of gasses or ions escaping through the tube 12. Accordingly, the tube 12 may be configured to prevent the ions from interacting with the inner surface walls 32 of the tube 12, as shown in
The circulator 14 is fluidly coupled to the tube 12. The circulator 14 is configured to move the charged fluids within the tube 12, circulating the charged fluids between the shielded and unshielded portions 28, 30. Thus, it should be appreciated by those skilled in the art that as the charged fluid flows through the unshielded portion 28, a force is generated. Specifically, the force is produced as the cross product of the earth's magnetic field vector and the direction of motion of the charged fluid as it flows through the unshielded portion 28 of the tube 12. Preferably, the circulator 14 is configured to produce a force sufficient to blow the charged fluid at a speed up to 10,000 miles per hour (as is known to be used in plasma cutting tools) but would classically be at the supersonic speeds of about 1,000 miles per hour. Any circulator 14 currently known and used in the art may be adapted for use herein, illustratively including centrifugal fans and axial flow fans and utilizing nozzles and venturi systems.
The device 10 may include a controller 34 configured to adjust the operation of the circulator 14 and the orientation of the tube 12. This may be done by adjusting the orientation of the platform 16 (such as through the use of a thruster 36) itself or the tube 12 may be rotatably mounted to the platform 12. It should be appreciated by those skilled in the art that the amount of force produced by the device is based upon the density of charged fluids within the tube 12, and the velocity of the charged fluids. In the instant case, the tube 12 is filled with a predetermined amount of charged fluid, and thus variation of the speed at which the charged fluid flows along the unshielded portion 30 will determine the amount of force produced as the earth's magnetic field is generally constant. Such a relationship may be surmised in the following equation:
{right arrow over (F)}=(q{right arrow over (v)})×{right arrow over (B)} Equation (1)
Wherein F is the force generated by the movement of the particle across the earth's magnetic field, q is the charge in coulombs of the particle(s), v is velocity of the particle in the field, and B is the strength of the magnetic field.
The controller 34 may be further configured to pivot the tube 12 or the platform 16 so as to adjust the angle at which the charged fluid passes the earth's magnetic field. In such a manner, the controller 34 is operable to tune the vector of the force, and thus propel the platform 16 in numerous directions. The device 10 may include a drive 38 configured to change the position of the tube 12 relative to the platform 16. The controller 34 may be electrically coupled to the drive 38 so as to rotate the tube 12.
With reference now to
There are numerous ways in which the ion generator 40 may generate ions. In one example, the ion generator 40 may be configured to deliver a high voltage input to ionize air molecules (or other fluid molecules) within the tube 12. In another example, lasers may be used to ionize the internal fluid. Yet another example may be to produce a highly ionized fluid in an external process and contain that highly ionized fluid in the tube 12. Accordingly, it should be appreciated by those skilled in the art that the embodiments described herein are illustrative of ways in which the ion generator 40 may take form, and should not be limiting to the scope of the invention. The power required to actuate the ion generator 40 may be provided by a power supply, such as a gas or electric engine, or a battery.
The ion generator 40 is fluidly coupled to the tube 12. It should be appreciated that the introduction of additional ions into the tube 12 increases the charge density of the charged fluid in the tube 12. In one embodiment the ion generator 40 produces a negatively charged fluid containing anions by introducing excess electrons into the fluid inside the tube 12. Alternatively, the ion generator 40 may produce a positively charged fluid containing cations by removing electrons from the fluid introduced to the tube 12. The charged fluid is held at approximately atmospheric pressure, and may be generated by many atmospheric pressure plasma generation devices, such as Capacitive discharge using RF ion generator 40s. Other, known atmospheric pressure plasma generators include corona discharge ionizers and dielectric barrier discharge ionizers. However, it should be appreciated that the use of low pressure or high pressure plasma is perfectly acceptable as long as high ionization is achieved in the fluid.
The controller 34 may be configured to actuate the ion generator 40, and blower, and control the angular displacement of the tube 12 with respect to the platform 16. The controller 34 may be linked to a driving control system (not shown) such as a pedal assembly and a steering wheel or a flight stick similar to one found in the cockpit of a jet. Thus, the controller 34 may be operable to propel the platform 16 in a desired direction and at a desired speed based upon the output from the drive control system.
As shown in the figures, the device 10 may be fully integrated to function as the drive for an automotive vehicle 50. The platform 16 is shaped like an automotive vehicle body. The platform 16 may include seats, an engine housing, and a cargo space. The vehicle 50 is shown as a two passenger vehicle, and the cargo space is approximately the same size as the passenger space. However, it should be appreciated that the platform 16 may be modified for group or cargo transportation.
The vehicle 50 further includes a tube 12 forming a closed loop. The tube 12 includes a shielded portion and an unshielded portion. The shielded portion is configured to prevent electro-magnetic forces from interfering with/countering the electro-magnetic forces generated by the unshielded portion. Any electro-magnetic shields that are currently known and used may be adapted for use herein, illustratively including a Faraday cage. Accordingly, shielded portion may be formed from a material such as copper, steel, iron, and any electrically conductive/reflective material.
The tube 12 is shown as having a generally rectangular shape. However, it should be appreciated by those skilled in the art that the tube 12 may be shaped otherwise. It should also be appreciated that the diameter and length of the tube 12 may be dimensioned so as to produce a desired flow rate for the charged fluid, and thus the Figures shown herein are illustrative and not limiting.
The interior of the tube 12 is generally a smooth surface so as to maximize the efficiency of fluids flowing within the tube 12. The tube 12 may also be configured to prevent deionization of the charged fluid flowing within the tube 12. It should be appreciated by those skilled in the art that preventing deionization increases the efficiency of the propulsion device 10 by reducing the frequency that the ion generator 40 must be actuated. Deionization may result from a charged particle reacting with the inner surface of the tube 12, and from the product of out-gassing from the tube 12. As used herein, out-gassing refers to the act of gas being released by the tube 12 into the charged fluid that would increase the de-ionization (or recombination) of the charged fluid in the tube 12. Accordingly, as described above, the tube 12 may include a layer 12a formed from a material configured to prevent the ions from interacting with the inner surface walls of the tube 12, as shown in
The vehicle 50 further includes an ion generator 40, and a circulator 14. The ion generator 40 is powered by a power supply such as a battery, a gas engine, or the like. The ion generator 40 is configured to introduce a charged fluid into the tube 12. In one embodiment, the charged fluids are ions having either a net positive or negative charge. The ion generator 40 may be used to augment existing charged fluids within a tube 12 loaded with a charged fluid. Alternatively, the ion generator 40 may be used to fill the tube 12 with ions.
The circulator 14 is fluidly coupled to the tube 12. For illustrative purposes, assume that the circulator 14 is a blower 14a and is configured to blow the charged fluids within the tube 12, circulating the charged fluids between the shielded and unshielded portions 28, 30. Thus, it should be appreciated by those skilled in the art that as the charged fluid flows through the unshielded portion 30, a force is generated. Specifically, the force is produced as the cross product of the magnetic field vector formed by the charged fluid flow through the unshielded portion 30 of the tube 12 and the external magnetic field. Preferably, the blower 14a is configured to produce a force sufficient to blow the charged fluid at a speed of up to 10,000 miles per hour (super sonic). Any blower 14a currently known and used in the art may be adapted for use herein, illustratively including centrifugal fans and axial flow fans.
The vehicle 50 includes a controller 34 configured to actuate the ion generator 40 and blower so as to produce a desired thrust. The vehicle 50 may further include a positioning drive 52 operatively mounted to the tube 12. The positioning drive 52 is configured to pivot the tube 12 with respect to the platform 16. As shown, the positioning drive 52 includes a plurality of pneumatic cylinders 52a configured to adjust the position of the tube 12 with respect to the vehicle 50. Thus, by extending one of the pneumatic cylinders 52a, the vector of the force may be adjusted to propel the vehicle in a desired direction. Thus, it should be appreciated that the vector of any force produced may be adjusted, and in such a manner the direction of the vehicle is adjusted.
The vehicle may further include a driving control system such as a pedal assembly and a steering wheel. The controller 34 is in electrical communication with the drive control system. The actuation of the pedal assembly and the steering wheel is transmitted to the controller 34, wherein the controller 34 may actuate the ion generator 40, blower and the positioning drive 52 so as to increase/decrease the charge within the tube 12, the rate at which the charged fluid flows through the tube 12, and the direction at which the force is generated. Thus, the controller 34 may be operable to propel the platform 16 in a desired direction and at a desired speed based upon the output from the drive control system.
The vehicle may further include a sensor 54 configured to detect the magnetic field in which the vehicle 50 is operating. Such sensors are currently known and used in the art and illustratively include a sensor 54 commonly referenced as a magnetometer. The sensor 54 and the controller 34 are in communication with each other. As shown in the equation above, the magnetic field will affect the force produced by the charge and velocity of the charged particle.
For example, the vehicle may operate in the Earth's magnetic field. A commonly accepted average value of the Earth's magnetic field is approximately 30 μT. The blower 14a is actuated so as to move the charged fluids at a speed of Mach 1, approximately 340 meters per second. The ion generator 40 may be actuated so as to produce a charged fluid having an ionization density of 1028 charged atoms per cubic centimeter. Equation 1 represents the force produced by the charged fluid moving at an angle to the external magnetic field.
{right arrow over (F)}=(q{right arrow over (v)})×{right arrow over (B)} Equation (1)
For this illustrative example the unshielded fluid flow will be assumed to be at a right angle to the Earth's magnetic field, and the shielding will be assumed to be completely effective. Equation 2 works out the force produced by the example values.
In operation, the air in the tube 12 is charged by the ion generator 40 forming a charged fluid, and the blower is actuated so as to move the charged fluid at a desired speed, wherein the positioning drive 52 is actuated so as to pivot the tube 12 at an angle to the external magnetic field so as to create a force in a desired vector.
The invention is not restricted to the illustrative examples and embodiments described above. The embodiments are not intended as limitations on the scope of the invention. Methods, apparatus, compositions, and the like described herein are exemplary and not intended as limitations on the scope of the invention. Changes therein and other uses will occur to those skilled in the art. For example, the vehicle may have a tube 12 filled with a predetermined amount of charged fluids so as to have a desired charge. In such an embodiment, it is conceivable that the vehicle does not include an ion generator 40, and that the desired force produced is achieved by actuation of the blower and orientation of the tube 12.
