Author Topic: Can a thruster using geomagnetic fields and superconductors generate a thrust?  (Read 605 times)

As shown in the figure, the thruster is equipped with a geomagnetic field convergence layer, which is a superconducting material. The geomagnetic field convergence layer repels and blocks the magnetic flux of the geomagnetic field, so that the magnetic flux of the geomagnetic field passes through the narrow area between the upper and lower convergence layers. The geomagnetic field intensity B in the narrow area between the convergent layers of the geomagnetic field is enhanced.The thruster is also equipped with a electrifying coil, and the lower end of the coil is located in a narrow area between the convergent layers.

All thrusters have to do work. Is this doing work against the earth's magnetic field? What energy is being put into the system to do the work? Electrical?

How is this better than an electrodynamic tether, which does work against the earth's magnetic field via current flow?

It against the Earth's magnetic field by electric current, you need to input electrical energy, and connect the battery at both ends of the coil. Because the earth's magnetic field is enhanced,Compared with electrodynamic tether, it has a greater driving force.

Forcing field lines into a smaller cross-section won't help you get more thrust per unit power.  The only way to do that is by reducing losses in the tether system, such as the heating of the tether or heating of other parts of the system (likely responsible for nearly all the losses).
