it just seems obvious to me that since electrons and electric fields carry kinetic energy (just let that sink in for a while, the efficiency of recovery of energy from a generator, then deployed to a motor is over 98% or some very high figure like this) that it should be possible to make them asymmetrically deliver it, and not have to create the equivalent of an explosion throwing one mass back to push the main mass forward i've been following this stuff about resonating electron flux emission devices like the Emdrive and i came to the conclusion that what they are digging at is inducing electrons to form a balanced pair in an extremely tight orbit that remains stable long enough to function as the ballistic projectile that is thrown backwards, by using a tesla coil and a dual chamber resonator with a pyrolitic carbon diamagnetic coating where the tesla coil emitter is located inside of, which works to catch the fast ones, and bring them back again to entrain the others that haven't caught the spin yet until they eventually escape from the emitter hole at the small end of the resonator i also have some vague ideas about a static, passive EMF capture coil that uses a tuned set of 5 capacitors to set up a spinning magnetic field that then catches like a whirlpool vortex and continues to accumulate magnetic flux until it reaches the capacity of the array's permeability, i'm pessimistic about how much energy it can catch, but it is possible that it can catch enough to be a practical source of energy for, for example, a carrier bolt thrower (uses a coil to pull the thrower with the nonferromagnetic projectile from the back to the middle of the device, not like a coil gun or rail gun) indeed, the tesla coil impulse generator, perhaps it can even be turned into a recoilless impulse blast if the impulse can be made coherent like a laser, and literally just punch things like it was a bullet, except at lightspeed!
