pretty cool, kind of like the idea these sattelites would harness sun for propulsion too :) not sure if it would be more efficient than powering their own propulsion with the already captured energy (i know nothing about this obv) i wonder a bit too, totally unrelated to the software engineering here. how would one get the power back to earth? :'? dont say photon rays :D but really how ?
