    Its a concept of a plane/blimp with wings that flying using gravity, never needs fuel, unlimited range. Took me 5 seconds to figure out what wrong with this concept.

    Er, conservation of energy. FAILED.

    The cycle of charging and discharging the compressed air tanks violates conservation of energy. There is no such thing as a free ride.

    Exactly! No maybe if it was solar powered it could work?

    Or have a surface that somehow changes between being white and black to regulate internal temperature with sunlight and hence create a sort of hot-air effect?

    There's plenty of surface area to utilise for solar panels, and that would make recharging the compressed air supply in flight feasible, although previous solar powered aircraft have used electric engines, and managed to stay aloft at night with energy stored in batteries, so that might be a better option.
