This is a concept that had been bouncing around in my head. Is there a feasible way of developing a vehicle to travel across a Planet's Magnetic Field Lines? Is there a way to develop an electromagnetic device that would replicate the effects of a superconductor pinning magnetic fields to hold its position.
In the mess of magnetic field lines that shield our planet, there are many shallower lines that may be capable of sending a ship into orbit. The ship could even field line hop to to change its orbiting distance. Thus can we create a vehicle that can entrap and coast through a magnetic field line and then hop its way into space and reduce the amount of fuel required to reach Karman Line?
Said vehicle could turn on the electromagnetic device partway through takeoff and reduce the amount of thrust required to keep it aloft. Then at its apex, turn off the device and blast off (Hop) to the next and larger field line. The pilots of the craft will continue to do this to gradually reach their desired height. Could this then be used to possibly reach the moon or other planets without using much fuel?
Would this type of flight even reduce fuel cost or increase it?
What do y'all think?
