Many thanks for the link .However, while the paper is convincing in term of theoretical orbital mechanics, I can't find any treatment of using solar sail attitude alone to manage torque and acceleration issues, for as the authors state, it "does not address practicality issues such as the

You don’t need a countervailing force, you just need to displace yourself sunward until the forces balance… (though how far depends on areal mass density, and displacing too far sunward will require greater area to shade the Earth if I recall right). But even if the propellant requirement is
