The LightSail 2 doesn't run on solar panels but instead solar sailing – an entirely different concept. It's kind of like a sailboat, but instead of using wind to make it move, it's powered by photon particles from the sun that bounce off of a sail made from a large reflective surface. The photon particles give it a "tiny push no stronger than the weight of a paperclip," Nye told CNN.
