Commutator noise from a dc motor will be seen as a (dependent) AC source by its supply battery. Does this small excitation of battery plates contribute to desulphination in a lead-acid battery? (i.e., is the commutator noise good for the battery?)

Can we measure the position of the LAGEOS satellites with enough resolution, such that after correcting for the influences of all the known major masses in our Solar System, they could be used as mass/gravity sensors? (i.e., by looking for deviations)
