Although the displacement distance above or below the equator is small - of the order of 10 to 50 km - work on hybrid solar sails, which use both light pressure and thrust from a conventional electric propulsion system, is underway and aims to improve the displacement distance.

Just to put things in perspective: at GEO altitudes, a 50 km displacement corresponds to a truly insignificant 0.07 degrees in elevation.

They'd need to get about 10 degrees of elevation shift for this idea to have any practical utility.

I seriously doubt they're anywhere close to that.

Are you kidding? They are going to be able to cram many times as many satellites up there if this thing works like it’s supposed to.
