Why would friction always be higher? In principle, this is just like an electric RC plane. You use the surrounding air for propulsion while keeping your own mass constant.

Any sort of energy harvesting and reuse is going to involve some sort of losses along the way. Plus not all surfaces of the craft will be energy harvesting so those parts are just straight air friction.

  The energy for the propulsion is coming from solar power.
