Did you know that many buldings in chicago were built with zepplin landings on the roofs... After the hindenburg they were repurposed but many are still there. Imagine a 15 min commut in a crowded city to the airport at the top of a skyscraper.
Beautiful. But the view would be better if the seating was in the lower half and not the top, and that would probably make it easier to get passengers on and off, too.
How does wind power work on an aircraft? You're expending energy to move relative to the air. If you then extract energy from the motion of air relative to the aircraft, that will slow you down. On the other hand, you have a very large top surface which seems like it could be a solar collector, if you can keep the weight down (e.g. dye/film type solar collectors).
Lastly, this will be slower than an aircraft. How much cheaper would it be for a passenger?
@MarcusMaximus: Actually a lighter-than-air craft will not have zero or negative weight. Negative weight is impossible without anti-gravity. The overall craft will have a density that is lower than air at the altitude that it flies. That is achieved by keeping the weight as low as possible (e.g. materials with high strength relative to their weight) and keeping the volume as high as possible (e.g. by having a huge compartment filled with very low density helium). Even plain old air has a positive weight. Helium also has weight, it's just lower than air so it has net lift.
In any case, I am talking about the weight of the solar cells themselves, not the total weight of the vehicle.
