While just a concept, a sky hotel that never has to land and gives visitors a unique vacation is a neat idea.
Idea being the key word as physics and aerodynamics might prevent such a ginormous aircraft from ever taking flight.
In the video, the aircraft, which is shown taking off from an airport, contains an entire hotel for up to 5,000 people. It features a rotating dining platform with 360° views of the sky. The sky hotel also includes an entertainment section with pools, shopping malls, bars, arcades, theaters, cinemas and much more.
The 20 electric engines of the aircraft are powered by a nuclear reactor that is unlimited, allowing it to never run out of energy, so it could stay in the air for years. It would get supplies and transport passengers via other aircraft docking with the sky hotel and unloading cargo and visitors.
The hotel also includes an entire hospital to help in case of a medical emergency or problems with air turbulence or air sickness.
Again, this is likely never to be a real thing, but it is fun to imagine what could be given the advance in technologies.
