With a propeller based system lift is provided by the differential in pressure above and below the rotating blades. The denser the air or the faster the blades travel through air the more more lift is generated. In thinner air there is very little lift generated so to counter this the blades have to move much faster to generate the same lift as in denser air. This is a downside of using propellers in thin air but other forms of propulsion would probably use to much energy to be recharged or replaced daily
