But I would answer your question with another - Why not tap the energy and use it recharging a battery? Batteries are well-characterized, very safe and stable; and they are off-the-shelf technology. They will probably beat a flywheel pound-for-pound in storage capacity, once flywheel shielding is taken into account. They suffer leakage current losses, but those are much less than the Q losses for a flywheel. And they will not introduce torque stresses onto the vehicle frame on every turn (flywheels will, even if mounted with opposing spins so that the vehicle as a whole is not spun). -- Richard Stead Center for Seismic Studies Arlington, VA stead@seismo.css.gov
