Expanding upon established research in the physics of particles in a magnetic field, Dr. Peck describes how a spacecraft can be made to accelerate in a direction perpendicular to a magnetic field, as do all electrostatically charged objects to some degree.
Evidence of Lorentz forces in action appears, for example, in new images from NASA's Cassini spacecraft: the rings of Jupiter and Saturn contain dust particles whose orbits are governed by these forces. Dr. Peck proposes to exploit this natural behavior on a larger scale, allowing spacecraft to be propelled by the same principle.
Here is how a spacecraft taking advantage of Lorentz-actuated forces would work. Spacecraft naturally acquire a charge as they travel through a planetary body's surrounding plasma, but the charge is typically not very high.
Thus, to achieve a useful force, it must boost its charge by emitting charged particles (such as ions or electrons) via a high-energy beam. As a suitably "charged" Lorentz-enabled spacecraft orbits a planet, the planetary magnetic field naturally deflects the spacecraft's path toward a direction perpendicular to the magnetic field lines, which also affects the spacecraft's velocity.
It does this in much the same way as electromagnetic forces steer the electron beam in the old cathode-ray TV sets to paint the picture on a TV screen. The effect is greater near the north and south poles where the magnetic field is denser. Since planetary magnetic fields rotate with the planet, that perpendicular acceleration can lie in a direction that adds energy to the spacecraft's orbit.
The results are remarkable: without propellant, a spacecraft can achieve new earth orbits, cancel out atmospheric drag, and establish new stable satellite formations. This means of propulsion can allow freight and passengers to be transported throughout the solar system, using planetary magnetic fields as stepping stones from planet to planet.

Now there is a start... ESG theory describes it all. The quest a true space drive.
But of course useless without a propellant-less inertial drive.
